More storms and high heat are coming Friday

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) – Temperatures hit 90° in Rockford for the first time this year, which is just over two weeks later than average.

Thunderstorms helped cool temperatures off, but we’ll stay very warm and stuffy through the evening and tonight. As a result, we won’t get much relief from the heat overnight.

It’s been a while since temperatures have been this hot, so here are some safety tips to keep in mind in this heat:

  1. Drink plenty of water; as tempting as alcoholic beverages may be in this heat, alcohol acts to dehydrate the body.
  2. Take frequent breaks to avoid over-exposure to the heat.
  3. Avoid outdoor activities during peak heating of the day (between 1 and 5 PM).
  4. Do not leave children or pets in vehicles.
  5. If feeling dizzy or nauseous, head indoors and cool yourself down.

As rain-cooled air pushes out from this first round of storms, forecast models develop a secondary line of thunderstorms across Wisconsin overnight.  This line of storms looks to dive into northern Illinois by early tomorrow morning, making Friday morning’s commute to work potentially wet. These storms may be strong again, with a slight chance for severe weather. Strong winds, hail, and heavy rainfall may be possible.

Tomorrow looks to be dry for most of the day, but of course more thunderstorms are possible tomorrow afternoon.  Not a washout by any stretch, but something to be mindful of if your evening plans take you to City Market. Storms will be isolated, so most locations may end up staying dry. There is a slight chance for strong to severe storms again, since the weather is so hot and humid.

Don’t look for the heat to go anywhere yet. Hot and humid weather will last through at least the weekend. Highs will be in the low 90’s both days, with Sunday approaching the middle 90’s. With dewpoints in the 70’s, we’ll see the heat index in the upper 90’s to near 100 degrees both days. Cooler weather is possible again next week, but the humidity is not likely to drop however.
