Time: 940 AM Thu September 15, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS - An upper-level disturbance, rich with moisture from the remnants of tropical cyclone Kay, is propagating across the intermountain west supporting a favorable environment for scattered showers and thunderstorms across the District. - High temperatures today will reach the upper 70s to low 80s, with surface dew points in the upper 40s to low 50s. Moderate rainfall is expected, with a chance for stronger storms to produce small hail, wind gusts up to 60mph, and briefly heavy rainfall. - As showers and thunderstorms taper off into the evening, skies will gradually clear through the overnight with cool and mild conditions expected into Friday. Overnight lows will drop into the mid 50's on the plains with upper 30's to low 40's across the foothills. STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers/isolated thunderstorms will produce a trace to 0.2"-0.4" in 10-30 minutes. A moderate to strong thunderstorms can produce 0.4-0.8" in 10-30 minutes. WORST CASE SCENARIO: A strong thunderstorm or training of thunderstorm cells has the potential to produce up to 0.8"-1.0" in 10-30 minutes. A LOOK AHEAD: Tomorrow will be a bit warmer with a slight chance for afternoon to evening showers and thunderstorms. Highs will reach the upper 70s to low 80s. The warming trend continues Saturday with high temperatures reaching the mid 80s under clear skies. High pressure ridging will build across the Great Plains next week, transporting warm, dry air into the state. As a result, Sunday and Monday will be sunny and uneventful with highs reaching the upper 80s to low 90s.

Time: 823 AM Wed September 14, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- COOLER TODAY WITH A GOOD CHANCE FOR SHOWERS/THUNDERSTORMS THIS AFTERNOON AND EVENING - High-pressure begins to break down today, combined with left over moisture from a tropical disturbance from the Pacific will bring a good chance for rain showers/thunderstorms this afternoon and evening. High temperatures today will reach a more seasonable upper 70's to low 80's this afternoon. - A few very weak isolated showers currently along the higher terrain, will continue to increase as the morning progresses with thunderstorm development likely along the Continental Divide by midday. These storm will move SW to NE between 10-15mph through the District, with the best chance for storms between 2-8pm with shower activity tapering off between 8-10pm. These storm motions should help limit point rainfall amounts. However with excess available moisture from the tropical disturbance, a LOW chance for Message issuance today as some storms have the potential for brief heavy rainfall, with the largest threat being a quick 0.5" in 10-30 minutes if stronger storms are able to develop. - As showers taper off into the evening, skies will gradually clear through the overnight with cool and mild conditions expected into Thursday. Overnight lows will drop into the mid to upper 50's on the plains with upper 40's to low 50's along the foothills. STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers/isolated thunderstorms will produce a trace to 0.2" in 10-30minutes. A moderate to strong thunderstorms can produce 0.2-0.5" in 10-30 minutes. WORST CASE SCENARIO: A slower moving thunderstorm or training of thunderstorm cells has the potential to produce up to 1.5" in 45-75 minutes. A LOOK AHEAD: This active weather pattern remains in place tomorrow with another good chance for afternoon and evening rain showers/thunderstorms, with a slight chance for overnight showers into Friday. Temperatures will be slightly cooler tomorrow with highs nearly 80 degrees in the afternoon. Warmer Friday as high temperatures reach the low 80's with a slight chance for another round of afternoon rain showers/isolated thunderstorms.

Time: 817 AM Tue September 13, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HOT, HAZY, BREEZY AND GENERALLY DRY - High-pressure will hold today leading to another day with above average temperatures as we once again flirt with 90 degrees this afternoon. Hazy conditions will increase today, especially for northern Colorado as wildfire smoke continues to increase from the west moves into the region today. Winds will likely pick up through the day as well with gust up to 25mph from the SSE this afternoon. - Clouds will be on the increase this afternoon as remnants from a tropical storm start to move into the region from the SW. This will bring a very slight chance for a few scattered rain showers/isolated thunderstorms. However, with very dry conditions at the surface, with dew points currently in the upper 20's, most if not all precipitation will struggle to reach the surface today. The best chance for any shower activity will be from 2-9pm, favoring the higher terrain along the foothills and Palmer Divide at this time. - Mild and dry conditions are expected through the overnight as temperatures drop into the mid 50's to low 60's on the plains with to low to mid 50's along the foothills. STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers/isolated thunderstorms will produce a trace to 0.1" in 10-30 minutes. A moderate rain shower/isolated thunderstorm could produce 0.1-0.3" in 10-30 minutes. WORST CASE SCENARIO: A moderate to strong rain shower/thunderstorm is able to develop and will have the potential to produce 0.3-0.8" in 45-60 minutes. A LOOK AHEAD: An uptick in moisture both at the surface an upper-levels tomorrow will bring a better chance for widespread rain showers/isolated thunderstorms, with the best chance for storm activity tomorrow afternoon and evening. A slight chance rain showers stick around through the overnight and into Thursday. Tomorrow's high temperatures will drop into a more seasonable low 80's. Slightly cooler Thursday with highs in the upper 70's to low 80's with another chance for afternoon/eve rain showers/isolated thunderstorms with a slight chance for overnight rain showers into Friday. Friday starts to warm back into the low 80's with a slight chance for a few afternoon rain showers/isolated thunderstorms, with skies clearing into the evening.

Highs today will only warm into the 40's over the foothills with low and mid 50's over the plains as cloud cover will remain in place all day. - A widespread light rain or mist/drizzle will continue through the morning with conditions slowly drying out this afternoon and evening. The more persistent precipitation will be through early afternoon then coverage of light showers/mist/drizzle is expected to decrease this afternoon and eventually dry out ahead of midnight tonight. Areas of fog will develop after midnight and will persist into Sunday morning. - Total precipitation overnight has generally ranged from 0.25-0.75" with isolated higher and lower amounts. Another 0.10-0.30" of moisture is expected through the day favoring up-slope prone areas in and near the foothills. Overnight lows will dip into the lower 40's over the plains with some 30's for the higher terrain. STORM RAINFALL POTENTIAL AND DURATION: Light rain showers and mist/drizzle will produce rainfall rates of a trace to 0.15" in 30-60 minutes. A LOOK AHEAD: Areas of fog early Sunday morning will give way to sunny/mostly sunny skies allowing temperatures to warm into the 70's to around 80 over the plains.

Time: 904 AM Fri September 9, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- COOL AIR HAS ARRIVED! RAIN SHOWERS AND MIST/DRIZZLE TO FILL IN LATER AFTERNOON AND CONTINUE OVERNIGHT - After record breaking heat over the past few days, cooler air has arrived behind a cold front that moved through overnight. Temperatures today will only warm into the 50's in the Front Range foothills with readings in the 60's to around 70 degrees over the plains. - Conditions will trend dry through much of the day but there will be a slight chance for a rain shower or very isolated weak thunderstorm this afternoon after 2 or 3pm. If a thunderstorm were to develop it would favor the foothills S of I-70 and over the crest of the Palmer Divide over Douglas County. Clouds will increase as the afternoon progresses with light rain showers and areas of mist/drizzle developing towards sunset. Light showers/mist/drizzle will fill in this evening and become widespread overnight as cooler air continues to filter into NE CO. Areas of fog may also develop overnight and persist into Saturday morning. - The majority of the precipitation will be light with prime time for widespread shower activity from roughly 6 or 7pm this evening until midday Saturday. Total moisture will likely range from 0.10-0.30" into Saturday morning with isolated higher and lower amounts possible. Temperatures overnight will dip into the 40's over the plains STORM RAINFALL POTENTIAL AND DURATION: Rain showers and areas of mist/drizzle will produce rainfall rates of a trace to 0.2" in 60 minutes. WORST CASE SCENARIO: An isolated thunderstorm is able to develop with the potential to produce rainfall rates of 0.1-0.3" in 10-30 minutes. A LOOK AHEAD: Cloudy and cool with light rain showers and areas of mist/drizzle through the first half of the day Saturday. Conditions will slowly dry out Saturday afternoon with dry conditions developing ahead of midnight. Temperatures Saturday will be even cooler than today in the 50's to around 60 over the plains with more cloud cover. Drier and warmer for Sunday.

Time: 846 AM Thu September 8, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- RECORD BREAKING HEAT ONCE AGAIN TODAY BUT BIG CHANGES ARE ON THE WAY - One more day of record breaking heat ahead of a cold front that will move through later this evening and overnight. Highs this afternoon will reach the mid 90's to around 100 degrees over the plains. Normal high for Denver today is 83 degrees, record high for Denver today is 94 degrees. The record high should easily be broken by early afternoon. There will continue to be haze/smoke from wildfires over the Pacific NW reducing visibilities and making for colorful sunsets. - Generally dry conditions are expected through the day but there may be a few isolated rain showers and possibly a high-based weak thunderstorm ahead of the front late this afternoon and evening. Better chances for rain showers will be behind the frontal passage overnight into daybreak on Friday but any moisture expected to be minimal. - Winds will be increasing overnight, becoming breezy at times from the N at 10-20mph, gusting to 25-30mph or more briefly. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and high-based weak thunderstorms will produce rainfall amounts of a trace to 0.2" in 10-30 minutes. WORST CASE SCENARIO: A moderate to strong thunderstorm is able to develop this evening with the potential to produce rainfall rates of 0.2-0.5" in 10-30 minutes. A LOOK AHEAD: Official high temperatures for Friday will likely be reached just after midnight tonight as readings through the day will generally be in the 60's to around 70 over the plains with 50's in the Front Range foothills. There will be better chances for afternoon showers and thunderstorms Friday afternoon with scattered rain showers expected to fill in during the evening and continue overnight into early Saturday morning. Friday evening to Saturday morning will be the best chances for wetting rain. Heavy rainfall is not expected as the cooler temperatures will likely favor stratiform rain showers versus convective thunderstorms.

Time: 833 AM Wed September 7, 2022 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HAZY AND DRY WITH RECORD BREAKING HEAT - The heat wave will continue today with temperatures topping out in the mid 90's to around 100 degrees over the plains with 80's in the Front Range foothills. Normal high for Denver today is 83 degrees and the record is 95 degrees. Haze/smoke from wildfires over the Pacific NW will obscure the sun and may keep temperatures down a couple degrees from their potential peak but the record high is expected to be easily broken today at DIA. - Skies will be virtually cloud free but the haze will hinder visibilities. There is no threat for precipitation with completely dry conditions. - Temperatures will continue mild overnight only falling into the 60's over the plains with 50's in the foothills. STORM RAINFALL POTENTIAL AND DURATION: No precipitation expected today or tonight. A LOOK AHEAD: Another day of record heat on Thursday with highs topping out in the upper 90's to lower 100's over the plains. A cold front will move through during the evening and may generate a few isolated rain showers or weak thunderstorms along with breezy winds. Much cooler Friday-Sunday behind the front with highs in the 60's and 70's along with chances for showers and weak thunderstorms. MONITOR NATIONAL WEATHER SERVICE FOR SEVERE WEATHER STATEMENTS.
