According to data from the National Weather Service (NWS) in Boulder, the temperature in Denver will reach 89 degrees on a cloudy day on Wednesday. The maximum wind speed is 21 miles per hour and the minimum temperature is 59 degrees. The probability of a storm in the afternoon is 30% and rises to 50% after sunset.
The Colorado Department of Public Health and Environment (CDPHE) has issued an Ozone Action Day alert to the Denver Metro because of the hot, stagnant weather that caused the ozone concentration in the smog to rise. On Wednesday, Denver will smoke until the rain dissipates. CDPHE lists Wednesday as an unhealthy air day for sensitive groups.
Wednesday’s storm will be most active in Gao County where heavy rainfall is likely to occur, threatening flash floods in burn scar areas.
NWS predicts that the temperature in Denver will be higher on Thursday, with a maximum temperature of 82 degrees. Most of the day is sunny, and the low temperature at night will drop to 60 degrees. The possibility of showers in the morning turns into a 40% possibility of thunderstorms in the afternoon.
Friday may be the wettest day of the week. Denver has a 50% chance of showers and thunderstorms after noon. The weather is clear and the maximum temperature is 83 degrees. The threat will continue into the evening when the temperature drops to 57 degrees.
The highs are expected to rise back to the 1990s later in the weekend or early next week.
