Long Term
(Friday through Tuesday night) Issued at 329pm CDT Wednesday April 17 2024

The above mentioned upper trough will continue east across the Great Lakes Friday and Saturday. The upper low aloft will still be fairly flat/zonal with possibly weak ridging in place. That'll still promote slightly more moderating temps. Could see an isolated location or 2 reach 90 degrees on Friday. That'll be within the realm of record highs for the local area.

As we go through the weekend, models show a shortwave on the backside of the northern trough moving through the region. This is what'll be needed to drive a cold front through the CWA (County Warning Area) on Sunday. Ample moisture in place with lift from the front will be a good setup for increasing showers and thunderstorms. Latest forecast depicts this with rain chances increasing to near 80% and rainfall totals around an inch. This cold front won't be particularly strong, so only looking at a day of below normal temps with moderating conditions quickly returning as well as above normal temps Tuesday onward.

Issued at 329pm CDT Wednesday April 17 2024

A surface high pressure centered east of the local coastal waters will remain generally in that position through the rest of this week and starting this weekend. That'll keep onshore flow in place, but weaker pressure gradient should limit wind speeds and sea/wave heights. Current global model runs indicate that a cold front will move through the coast waters Sunday afternoon. Cold air advection won't be particularly strong with this boundary and thus likely only looking at about 12 to 18 hours of Exercise Caution conditions.
