Forecasters are now saying the cool down with rain they once predicted for Wednesday will not be as strong as initially thought.
According to the National Weather Service (NWS) in Boulder, Denver will be 89 degrees under cloudy skies on Wednesday. Winds could gust up to 21 mph with a low of 59 degrees. There’s a 30% chance for afternoon storms, which jumps up to 50% after sunset.
The Colorado Department of Public Health and Environment (CDPHE) has issued an Ozone Action Day Alert for metro Denver due to hot, stagnant weather allowing ozone concentrations to build from smoke. Denver will be smoky on Wednesday until rain knocks out the smoke. CDPHE lists Wednesday as an unhealthy air day for sensitive groups.
Wednesday’s storms will be most active in the high county where there’s a possibility of heavy rainfall, bringing a threat of flash floods to burn scar areas.
The NWS predicts Denver to cool more on Thursday, with a high of 82 degrees. The day will be mostly sunny, and the nighttime low will dip to 60 degrees. A possibility of morning showers will turn into a 40% chance of thunderstorms in the afternoon.
Friday could be the wettest day of the week. Denver has a 50% chance of showers and thunderstorms after noon on a mostly sunny day with a high of 83 degrees. The threat will last into the evening, with temperatures dropping to 57 degrees.
Highs are expected to climb back into the 90s later in the weekend or early next week.
