Meteorologist Madeline Evans’ First Warning Forecast

We are tracking some showers and storms popping up this afternoon with some heavy downpours and lightning possible but we are not expecting any of this to go severe. A few pop up showers and storms will linger for some in the evening then clear out overnight. Temperatures this afternoon are in the upper 80s and low 90s with heat index values breaking into the triple digits. We will cool off into the upper 70s overnight.

Tomorrow some of us will start off the first day of school with some patchy fog. By the afternoon highs will reach the upper 80s and low 90s again, above normal for this time of year. Expect partly cloudy skies with another chance for an afternoon “pop up” shower/storm. We should see a bit more sunshine in the mix for Wednesday and Thursday with an even slimmer rain chance. Highs will stay in the upper 80s through Friday.

We will be tracking a cold front set to move in this weekend. That front will likely drop our temperatures into the low to mid 80s which is near normal but will also bring in more clouds and an increased chance for showers and storms.

Today: Partly Cloudy, Isolated Showers/Storms (20%). Highs in the upper 80s. Winds: SW/E 5-10

Tonight: Partly Cloudy, Isolated Showers/Storms (20%). Lows in the mid 70s. Winds: S 5-10

Tomorrow: Partly Cloudy, Isolated Showers/Storms (20%). Highs in the upper 80s. Winds: S/E 5-10
