Tracking heat and humidity, spot storms tonight

TONIGHT: Partly cloudy with a spot storm possible. Lows in the upper 80s.

TOMORROW: Morning showers and storms possible north of Highway 24. Highs in the mid-upper 90s. Heat index between 104-108.

EXTENDED: Showers and storms are expected to redevelop just to our north tonight into Thursday morning along the edge of high pressure, and a few of these may once again clip areas north of I-70. Any storms that develop around sunset could produce brief heavy rain and isolated gusty winds. Thursday is another dangerously hot day as our Weather Alert Day continues for heat indices reaching between 105-110. Showers and storms will be possible Thursday night into Friday as a stubborn front finally begins to slide southeast, cooling temperatures into the lower 90s by Friday afternoon. Behind the front on Saturday, showers exit early, leaving us with temperatures hovering near or just under 90 degrees with lower humidity. Next week looks hot again to start off, but we could see a pattern change by late week that will bring northwesterly upper flow. That will allow temperatures to drop to near normal with lower humidity.
