Time: 913 AM Tue July 13, 2021 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- THUNDERSTORM ACTIVITY RETURNS TO THE DISTRICT - Hazy conditions continue to impact visibility today with temperatures warming into the upper 80's to lower 90's over the plains and upper 70's to 80's in the Front Range foothills. Mid and upper level moisture is on the increase and will lead to a return of thunderstorm activity over the District. - Surface moisture is only modest at best and will result in the storms that develop today generally producing light rain and gusty winds over the plains. The foothills stand a better chance for a stronger storm to produce brief moderate rain. An isolated sprinkle cannot be ruled this morning with thunderstorms developing over the higher terrain by around noon. By early afternoon chances for thunderstorms will spread out onto the plains. Isolated to widely scattered thunderstorm coverage is expected through the afternoon and may linger until around 10pm this evening. - Upper level steering winds responsible for importing the smoke but will also steer storms is from NW to SE at around 20mph. Individual thunderstorms will be relatively fast moving with training of thunderstorm cells or a briefly anchored thunderstorm possibly producing an extended period of moderate rain. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.1" of rain. Moderate and briefly strong thunderstorms will have the potential to produce 0.1-0.4" of rain in 10-30 minutes. WORST CASE SCENARIO: Training of thunderstorm cells or a briefly anchored strong thunderstorm may result in 0.3-0.8" of rain in 15-45 minutes. A LOOK AHEAD: A cold front will move through on Wednesday and lower temperatures into the 80's for highs over the plains. The front will increase surface moisture and result in stronger thunderstorms capable of producing heavy rainfall that may lead to excessive runoff. Scattered to numerous storms are expected with chances extending well into the evening Wednesday. Stronger storms may also become severe with large hail and gusty winds being the primary threats.

Time: 812 AM Mon July 12, 2021 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- CONTINUED HAZY WITH GENERALLY DRY CONDITIONS - Smoke from multiple wildfires to the NW of Colorado will continue to impact visibility today over the District with hazy skies. Temperatures will warm into the lower 90's over the plains with 70's and 80's in the Front Range foothills. - Most areas will squeeze out another dry day today with any afternoon thunderstorm activity expected to remain over the higher mountains to the W of the District but a stray storm or two cannot be completely ruled out, mainly over the far W and S areas. If a storm were to develop, best chances would be between 3-8pm with minimal rainfall and gusty winds being the most likely outcome. - After 8 or 9pm dry completely dry conditions are expected for the remainder of the evening and overnight. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak high-based thunderstorms will produce a trace to 0.1" of rain. A very isolated moderate storm may result in up to 0.2" in 10-30 minutes. A LOOK AHEAD: Temperatures back off a degree or two on Tuesday, mainly due to increased cloud cover earlier in the day. There will be an increase in mid and upper level moisture as well and will result in additional thunderstorm activity. Widely scattered afternoon thunderstorms are expected with most storms producing light to briefly moderate rain and gusty winds. Thunderstorm chances look to peak on Wednesday as a cold front moves through with some storms possibly producing brief heavy rainfall.

Time: 809 AM Sun July 11, 2021 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- SUNNY AND DRY BUT HAZY... - Conditions will be completely dry over the District today with virtually cloud free skies but there will be plenty of haze due to smoke from multiple wildfires to the NW of Colorado. The haze will impact visibility and likely result in some extra color at sunset if anything positive can be said for smoke in the sky. - No precipitation is expected within the District and over the entire state for that matter! One of the few days this summer when the entire state is likely storm free. - Temperatures will be warming back into the upper 80's to lower 90's for highs over the plains with 70's and 80's in the Front Range foothills. STORM RAINFALL POTENTIAL AND DURATION: No precipitation today or tonight. A LOOK AHEAD: On Monday isolated afternoon thunderstorms return to the District with temperatures warming into the mid and upper 90's for highs. Storms that develop Monday will generally produce minimal rainfall and gusty winds. A little cooler Tuesday mainly due to increased cloud cover earlier in the day. An uptick in moisture is expected and will lead to more numerous afternoon and evening thunderstorms. Some storms may become strong to severe and have the potential to produce brief heavy rain.

Time: 203 PM Fri July 9, 2021 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- MOISTURE NORTH OF THE DISTRICT MAY COME INTO PLAY LATER THIS AFTERNOON... - Easterly surface winds have increased surface moisture, in particular N of the District with dew points well into the 50's over Weld and Larimer Counties. As the afternoon progresses stronger storms are expected to develop over northern Colorado and may produce a rain cooled gust front that moves south into the District supplying a trigger for storms as well as importing additional moisture. - If all the ingredients come together just right a strong storms with brief heavy rainfall cannot be ruled out later this afternoon or evening resulting in a LOW Message potential. The most likely outcome is higher based weak to moderate thunderstorms producing light to briefly moderate rain with enhanced moisture remaining north. - Upper level steering winds are from NW to SE at 20-25mph keeping rainfall brief. An outflow boundary or gust front may allow for a storm to anchor briefly and produce prolonged periods of rainfall. Best chances for thunderstorm activity is through about sunset. STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.2" in 10-30 minutes. Moderate to strong thunderstorms will have the potential to produce 0.2-0.6" in 10-30 minutes. WORST CASE SCENARIO: A slower moving strong thunderstorm may result in up to 1.3" in 45-60 minutes. A LOOK AHEAD: A reprieve from the heat this weekend as cooler temperatures ascend on us from the north. A very slight chance for rain showers/isolated thunderstorms Saturday afternoon with heavy rainfall not anticipated at this time. Saturday and Sunday will be cooler with temperatures in the low to mid 80's. Dry conditions are likely both Sunday and Monday with storm chances picking up into Tuesday.

Time: 822 AM Fri July 9, 2021 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- ANOTHER HOT DAY WITH SCATTERED HIGH-BASED AFTERNOON RAIN SHOWERS/ISOLATED THUNDERSTORMS - Another hot day with record breaking heat as we approach triple digits once again. The record high temperature today at DIA is 98 degrees set in 1989. We should be at or above that just after midday. - Similar to yesterday, a slight chance for high-based afternoon rain showers/isolated thunderstorms. With high temps and low-level surface moisture mixing out this afternoon the largest threat today will be gusty winds and the occasional lightning strike as most precipitation will struggle to reach the surface. Best chance for storms today will be from 2-8pm with a few lingering sprinkles to light rain after 8pm. - A cold front moves in overnight bringing breezy to gusty north winds through the evening and into Saturday morning. Overnight lows will drop into the low to mid 60's with a chance for patchy fog into Saturday morning. STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will produce a trace to 0.1" in 10-30 minutes. A weak to moderate thunderstorm will produce 0.1-0.3" in 10-30 minutes. WORST CASE SCENARIO: A slower moving moderate thunderstorm or training of weak to moderate thunderstorm cells have the potential to produce 0.3-0.6" in 45-60 minutes. A LOOK AHEAD: A reprieve from the heat this weekend as cooler temperatures ascend on us from the north. A very slight chance for rain showers/isolated thunderstorms Saturday afternoon with no heavy rainfall threat expected. Saturday and Sunday will be cooler with temperatures in the low to mid 80's.

Time: 846 AM Thu July 8, 2021 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HOT TODAY WITH A SLIGHT CHANCE FOR HIGH-BASED AFTERNOON RAIN SHOWERS/ISOLATED THUNDERSTORMS - A small heat wave is in store for the District over the next couple of days as temperatures are expected to reach triple digits in some areas this afternoon. - A slight chance for high-based afternoon rain showers/isolated thunderstorms, although with nearly 100 degree high temperatures and quickly dropping dew points this afternoon, any rainfall today will struggle to reach the surface resulting in gusty winds to be the largest threat for today. A few isolated thunderstorms cannot be completely ruled out today as well, with the potential for some rain and possibly a few lightning strikes. Best chance for storms today will be from 2-8pm with skies gradually clearing through the overnight and into Friday. - Overnight will be mild with lows in the mid to upper 60's along the plains with upper 50's to low 60's along the foothills. STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers and weak thunderstorms will produce a trace-0.1" in 10-30 minutes. A moderate rain shower/thunderstorm will produce 0.1-0.3" in 10-30 minutes. WORST CASE SCENARIO: A stationary thunderstorm, or training of thunderstorm cells has the potential to produce 0.3-0.6" in 45-75 minutes. A LOOK AHEAD: Another hot day tomorrow with storm chances picking up slightly in the afternoon and early evening. A weak cold front moves in overnight and into Saturday which will lower high temperatures into the 80's. A very slight chance for rain showers and thunderstorms on Saturday, mainly focusing on the foothills and Palmer Divide.
