Time: 830 AM Tue June 20, 2023 Forecaster: Brad Simmons ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- DRY WITH DECREASING CLOUDS AND SLIGHTLY ABOVE NORMAL TEMPERATURES/SUMMER OFFICIALLY BEGINS TOMORROW! Many areas in and around the District reached or exceeded 90 degrees for the first time this year yesterday but the official reporting station for Denver (DIA) only reached a high of 87 degrees, keeping the first official 90 degree day for Denver somewhere in the future. Temperatures will be a little cooler today, mainly due to periods of cloud cover this morning but skies will become mostly sunny this afternoon and temperatures will still warm into the mid 80s to around 90 over the plains. Normal high for the date is 85 degrees. Even though there will be periods of cloud cover, mainly this morning, conditions will be dry today in and around the District with any thunderstorm activity confined to the far NE corner of the state. Winds will be breezy at times gusting up to 20mph or more this afternoon. STORM RAINFALL POTENTIAL AND DURATION: No precipitation expected today and tonight. A LOOK AHEAD: The summer solstice will occur on Wednesday and will be the longest day of the year and the start of the summer season. Thunderstorms will return to the forecast in the late afternoon or evening with widely scattered storms expected. The storms that develop late Wednesday afternoon and evening will have the potential to become strong to severe producing brief heavy rainfall, hail and gusty winds. Afternoon highs Wednesday will be in the mid to upper 80’s over the plains. Cooler Thursday and with plenty of moisture to work with thunderstorms are likely Thursday afternoon and evening. Stronger storms will be very capable of producing heavy rainfall and possibly hail. Conditions dry out on Friday and continue on the drier side over the upcoming weekend.
