Time: 850 AM Tue June 21, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- SLIGHTLY COOLER, PARTLY CLOUDY AND DRY TODAY - Today is the first day of Summer, however, a cold front that moved through the region late last night has ushered in a cooler airmass as high temperatures drop into the upper 70's to low 80's on the plains with low to mid 70's along the foothills this afternoon. - Winds will be breezy from the S/SE throughout the day today with gusts up to 30mph this afternoon. Winds will calm into the evening with mild and dry conditions expected into this evening. - Overnight lows will drop into the mid 50's to around 60Â°F on the plains with low 50's along the foothills with continued dry conditions through daybreak Wednesday. STORM RAINFALL POTENTIAL AND DURATION: No precipitation is expected today or this evening. A LOOK AHEAD: Wednesday will be mild and dry for the most part with a very slight chance for scattered afternoon/early evening rain showers/isolated thunderstorms, however, most areas will likely remain on the dry side. A slight better chance for rain showers/isolated thunderstorms Thursday afternoon and early evening with minimal rain chances once again. A stronger disturbance moves into the region Friday which will bring a good chance for rain showers/thunderstorms with a decent chance for moderate to brief heavy rainfall at this time.

Time: 859 AM Sun June 19, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- WARM AND BREEZY WITH A CHANCE FOR SCATTERED AFTERNOON/EARLY EVE RAIN SHOWERS/THUNDERSTORMS - Mid to upper-level monsoonal moisture continues to move into the region today leading to another chance for moderate to brief heavy rainfall this afternoon and early evening. Currently temperatures already in the mid to upper 70's and will increase into the mid 80's to around 90Â°F this afternoon. Breezy winds out of the SSW will remain throughout the day with gusts between 25-35mph at times. - Scattered rain showers/thunderstorms likely this afternoon, best chance will be between 1-9pm with 1-3 rounds of rain showers and isolated thunderstorms expected into the early evening. Storm motions will be fairly brisk from the SSW to NNE between 15-25mph, helping limit point rainfall amounts, however, training of thunderstorms today could lead to an increase chance for longer lasting moderate to briefly heavy rainfall. Storm today will also produce gusty winds along with hail up to 1" in diameter resulting in a very low chance for storms to become severe this afternoon. - By sunset, rain shower activity and breezy conditions decrease as skies gradually clearing through the overnight and into Monday morning. Overnight lows will drop into the upper 50's to low 60's on the plains with low to mid 50's along the foothills. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.2" 10-30 minutes. Moderate to briefly strong thunderstorms will have the potential to produce rainfall rates of 0.2-0.5" in 10-30 minutes. WORST CASE SCENARIO: A stronger thunderstorm or training of thunderstorm cells may result in up to 1.0" of rainfall in 45-60 minutes. A LOOK AHEAD: Conditions dry out Monday as high-pressure starts to build back over the region. This will lead to similar high temperatures in the upper 80's to low 90's across the District along with continued breezy conditions throughout the day. A cold front moves through Tuesday, effectively dropping high temperatures into the 80's with a slight chance for a few rain showers/isolated thunderstorms, mainly along the Palmer Divide at this time. A better chance for rain showers for the District Wednesday, however the threat for heavy rainfall remains minimal at best.

Time: 152 PM Sat June 18, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- SHOWERS AND THUNDERSTORMS TO IMPACT THE DISTRICT INTO THE EVENING/HEAVY RAINFALL THREAT LOWERING - Temperatures have reached the upper 80's to lower 90's over the plains as of 1:45 PM with abundant moisture in the mid and upper levels being imported from the south. At the surface, moisture levels have backed off with dew points currently ranging from the upper 30's to mid 40's. Due to the decrease in surface moisture from this morning the threat for heavy rainfall is lower but not completely eliminated. Storms are just now beginning to develop over southern and western areas of the District over Douglas and Jefferson Counties. - Fast individual storm motions from SSW to NNE at around 25mph will keep the storms that develop today moving along at a rapid pace reducing point rainfall amounts from a single storm. Most storms will produce light to briefly moderate rain and gusty winds. A stronger thunderstorm cannot be ruled out but chances have decreased. Training of thunderstorm cells may create an opportunity for longer durations of moderate to briefly heavy rainfall. - 1-3 rounds of showers and thunderstorms are expected into the evening. Best chances for thunderstorms will be through 9 or 10pm. Beyond 10pm any shower activity will be light in nature with minimal accumulation. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.2" 10-30 minutes. Moderate to briefly strong thunderstorms will have the potential to produce rainfall rates of 0.2-0.5" in 10-30 minutes. WORST CASE SCENARIO: Training of thunderstorm cells may result in up to 1.0" of rainfall in 45-75 minutes. A LOOK AHEAD: Another active day on Sunday with monsoon moisture impacting the District leading to scattered afternoon and evening thunderstorms. Storm motions will be relatively fast leading to the potential for brief bouts of moderate/heavy rainfall. Temperatures will continue to retreat with highs in the 80's to around 90 over the plains. Conditions dry out on Monday but temperatures remain in the 80s to around 90 for afternoon highs.

Time: 932 AM Sat June 18, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- THUNDERSTORM ACTIVITY INCREASES/BRIEF MODERATE TO HEAVY RAINFALL LIKELY - Flow aloft from the S/SW will import subtropical "monsoon" moisture in the mid and upper levels of the atmosphere into the District today resulting in an increase in thunderstorm activity. Temperatures will be held down due to more cloud cover today with highs topping out in the upper 80's to mid 90's over the plains with 70's and 80's in the Front Range foothills. Surface winds will be breezy at times from the S/SE gusting to 20mph or more. - Showers and thunderstorms will be on the increase between 11am and 1pm with best chances for thunderstorm activity through about 10pm then additional rain showers continue possible into the early overnight period. Fast storm motions from SSW to NNE at 25-30mph will help to reduce point rainfall amounts from a single storm, keeping the heavier rains brief in duration. Training of thunderstorm cells over a single point may result in extended periods of moderate to heavy rainfall that may lead to excessive runoff. Stronger thunderstorms may also contain gusty winds, and hail. - Multiple rounds of showers and thunderstorm are likely from early afternoon into the evening. Thunderstorm coverage over the plains is expected to be widely scattered with more numerous storms over the foothills. After 9 or 10pm the threat for thunderstorms diminish with any additional rainfall being on the light side. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.3" 10-30 minutes. Moderate to strong thunderstorms will have the potential to produce rainfall rates of 0.3-0.8" in 10-30 minutes. WORST CASE SCENARIO: Training of thunderstorm cells may result in up to 1.6" of rainfall in 45-75 minutes. A LOOK AHEAD: Another active day on Sunday with monsoon moisture impacting the District leading to scattered afternoon and evening thunderstorms. Storm motions will continue to be fast leading to brief bouts of heavy rainfall. Temperatures will continue to retreat with highs in the 80's to around 90 over the plains. Conditions dry out on Monday but temperatures remain in the 80s to around 90 for afternoon highs.

Time: 947 AM Fri June 17, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HOT/HAZY WITH AFTERNOON/EVENING THUNDERSTORM ACTIVITY FAVORING THE FOOTHILLS - The warming trend will reach a peak today with afternoon high temperatures topping out in the mid 90's to around 100 degrees over the plains. Foothills will be cooler in the 80's. Hazy conditions will continue as southerly upper level winds import more smoke from wildfires over AZ/NM. The southerly upper level winds are also importing moisture in the mid and upper levels but the majority of the moisture will remain over the mountainous areas of the state today, but will lead to better storm chances over the District this weekend increasing the heavy rainfall threat. - Shower and thunderstorm activity will develop W of the District over the mountains and higher foothills as early as noon. Outflow from initial thunderstorm activity over the foothills pushing eastward will be the most likely culprit for storm development over the plains. By 1-2pm isolated thunderstorms become possible over the plains with chances going through sunset. Storm coverage will be isolated lower elevations favoring areas along and W of I-25 and scattered over the foothills, favoring Boulder County. With ample surface moisture the storms that develop today, although far and few between over lower elevations will be capable of producing brief heavy rainfall. - Upper level steering winds from S to N at 20-25mph will be responsible for keeping most of the storm activity over the higher terrain as there will be little eastward progression. The relatively fast storm motions will help to reduce point rainfall amounts from a single storm cell, but training of thunderstorm cells would produce extended periods of moderate to heavy rainfall that may lead to excessive runoff resulting in a LOW Message potential today over the majority of the District. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.3" of rainfall. Moderate to strong thunderstorms will have the potential to produce rainfall rates of 0.3-0.9" in 10-30 minutes. WORST CASE SCENARIO: Training of strong thunderstorm cells may result in up to 1.6" of rain in 45-60 minutes. A LOOK AHEAD: Thunderstorm activity will be increasing over the weekend as temperatures begin to lower into early next week. Ample moisture at the surface and aloft will result in thunderstorms that develop over the coming days having the potential to produce brief heavy rainfall. Temperatures on Saturday remain above seasonal averages in the low and mid 90's over the plains and continue to cool Sunday with readings in the upper 80's to lower 90's.

Time: 928 AM Thu June 16, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HOT WITH SMOKE/HAZE ON THE INCREASE AND POSSIBLY AN ISOLATED EVENING THUNDERSTORM - Temperatures will continue to warm today over the District with afternoon highs topping out in the 90's over the plains with 80's in the Front Range foothills under sunny to mostly sunny skies through much of the day. Surface winds will become breezy at times varying from SW to SE at 5-15mph and gusts to 20mph or more. - SW flow aloft will begin to import smoke from wildfires over AZ/NM northward into Colorado as the day progresses with haze on the increase and air quality deteriorating. Hazy conditions are expected to persist over the coming days. Moisture will be increasing at the surface and aloft as the day wears on and an isolated evening thunderstorm or two may develop over southern and eastern areas of the District if all the ingredients come together just right. The most likely outcome is that the District squeaks out one more dry day before thunderstorms become more active over NE Colorado tomorrow and over the weekend. - The chances are relatively low but if thunderstorms were to develop today they would favor the plains over the foothills, initiating sometime between 5-7pm. Storms would then quickly lift to the NE with chances ending before midnight. The one fly in the ointment is that although the chances for storms to develop are quite low, if a storm does manage to develop it would likely become strong with the potential for brief moderate/heavy rainfall and gusty winds resulting in a low Message potential for eastern areas of the District. STORM RAINFALL POTENTIAL AND DURATION: Weak to moderate thunderstorms if able to develop will have the potential to produce a trace to 0.2" or rain in 10-30 minutes. WORST CASE SCENARIO: Moisture levels increase sufficiently at the surface to support strong thunderstorms with the potential to produce heavy rainfall rates of 0.3-0.9" in 10-30 minutes. A LOOK AHEAD: Temperatures will tack on a few more degrees on Friday with readings in the 90's to near 100 degrees over the plains. There will be a little relief from the heat for some as thunderstorm activity is expected to increase with isolated to widely scattered afternoon thunderstorms, more numerous over the foothills. Stronger storms will have the potential to produce gusty winds and moderate to briefly heavy rain. Chances for thunderstorms increases further over the weekend with stronger storms capable of producing heavy rainfall that may lead to excessive runoff. The first Message 1's of the season will be likely over the coming days!

Time: 859 AM Wed June 15, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- DRY AND WARM WITH ABUNDANT SUNSHINE - Conditions will be dry over the entire state of Colorado today with abundant sunshine making for sunny to mostly sunny skies. Upper level winds will be from the W keeping the smoke from wildfires over AZ/NM to the south but upper level winds will be turning more southerly over the coming days with smoke/haze on the increase tomorrow. - Highs this afternoon will peak in the mid to upper 80's over the plains with 70's in the Front Range foothills. Winds will be variable in the 5-15mph range with occasional higher gusts. - Overnight conditions remain dry with lows into Thursday morning in the 50's over the plains with 40's in the foothills. STORM RAINFALL POTENTIAL AND DURATION: No precipitation today and tonight. A LOOK AHEAD: Upper level winds turn more S/SW over the next couple days, initially this will import smoke from wildfires over AZ/NM making for smoky/hazy conditions but at time progresses this southerly flow will begin to import moisture. The moisture increase will also result in much better chances for thunderstorm activity on Friday and more so on Saturday and Sunday. Although the storm coverage is expected to be isolated to widely scattered over the plains some storms may be capable of producing moderate to heavy rainfall. Thunderstorm coverage will be higher over the foothills with better chances for meaningful rain. MONITOR NATIONAL WEATHER SERVICE FOR SEVERE WEATHER STATEMENTS.

Time: 925 AM Tue June 14, 2022 Forecaster: Laura Smith ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- WARM, DRY, AND SUNNY FOLLOWING LAST NIGHT'S COLD FRONT - An upper level trough propagating into the intermountain west has displaced the heat dome east. The accompanying cold frontal passage swept across the District last night, bringing welcomed relief from triple-digit temperatures. - Dry conditions are expected to persist today. The cool airmass will restrict high temperatures to the mid 80's, and morning clouds are expected to dissipate as surface dew points drop into the mid 20's by the afternoon. - Tonight, overnight lows will fall into the low 50 with dry conditions continuing through tomorrow morning. STORM RAINFALL POTENTIAL AND DURATION: No rainfall is expected across the District today. A LOOK AHEAD: Another dome of high pressure will begin building over the Desert Southwest on Wednesday as temperatures across the Front Range Urban Corridor reach the mid to upper 80's with dry conditions.
