Strong Heat Wave Moving In

We had a nice summer day with sunshine and temperatures hitting the mid 80's this afternoon, but that's nothing compared to what we're going to be seeing as we head into the weekend.  Excessive Heat Warnings have been issued for much of the Stateline, starting Friday at 11am and going through Saturday until 7pm, with some hot weather lingering into Sunday as well.


As for this evening, a quick passing shower will be possible for Carroll and Whiteside counties, but otherwise we stay dry for the evening with mostly cloudy skies and temperatures in the low 80's.  We cool to the mid 70's overnight, with isolated storm chances increasing as we get closer to 7am Friday morning, when a warm front moves into our area.

After 10am the front moves out, and then we stay dry heading through Friday afternoon with partly cloudy skies and temperatures hitting the mid 90's.

The setup for this next heat wave includes an upper-level trough to the west, which will build instability at the surface and allow for a low pressure system to develop in that area.

That low will then track northeast along the jet, continuously pulling hot, humid air into our area during that time, for both Friday and Saturday.  This will bring temperatures into the mid 90's for both days, but Heat Indices will be in the mid 100's for both days. Very hot!! 

The Dew Point Temperatures are really what will be making it feel much hotter outside.  Dew Points are expected to be in the upper 70's for both Friday and Saturday.  The high heat and humidity will allow for a couple pop-up thunderstorms for Friday and Saturday afternoon, but mostly we stay dry.

Definitely stay safe if heading outside Friday or Saturday.  Have water by you at all times, and have easy access to shade or other cool areas as your body can become de-hydrated and over-heated quickly in these conditions.
