Morning storms delay Heat Advisory

Remaining Ad Time Ad - 00:00

MADISON (WKOW) — A batch of showers and thunderstorms that produced heavy rain with rainfall rates up to 2″ this morning has finally pushed out of southern Wisconsin, and we should see some clearing by afternoon.

Expect increasing sunshine with very hot and humid conditions! Highs will hit the upper 80s with heat indexes between 95 and 105°. Storms will be possible again at night, especially north.

The Heat Advisory is now in effect starting at 10 a.m. on Friday and lasts through 11 p.m. For Crawford and Grant Counties, the Excessive Heat Warning is in effect now until 7 p.m. on Saturday.

Friday is the hottest day in the forecast with temps in the mid-90s and heat index values around 103°-114°.

Saturday will be the transition day out of the heat as a sweeping cold front moves in. Showers and storms will develop ahead of the front especially in the afternoon and evening. Temps in the low 90s and heat index values around 93°-103°. Those who see rain will be cooler.

Much more comfortable conditions are in store for Sunday and most of next week. You can get the full 27 Storm Track forecast here.

Longtime exposure to this level of heat is particularly dangerous for the elderly, very young children and pets.

There are a few important things to keep in mind when we experience excessive summer heat.

  1. Look before you lock! It is NEVER safe to leave children or animals locked in a turned-off car. Temperatures heat up much faster in the sun and can be extremely dangerous.
  2. Stay hydrated! Limit strenuous activity outside, find shade, wear sunscreen and take many breaks.
  3. Check on your elderly neighbors and those without air conditioning.

Stay up to date with the latest weather forecast, especially if you have outdoor plans this week.
