A likely Progressive Derecho will rake areas from Manitoba to Ohio & even as far southeast as the Virginia area later today, through tonight & into tomorrow.
The hardest hit areas look to be northeastern Minnesota, Wisconsin to southern Lower Michigan with swaths of +75 mph gusts possible.
Here, it still looks like it is our northeastern counties that have the best potential of any severe weather. This would tend to be northeast of a Demotte to Logansport to Grissom line (SLIGHT RISK or Level 2 up from northern Jasper to northeast White to Cass to Miami counties & northeastward). There, a few gusts +58 mph cannot be ruled out in the 4:30-7:30 a.m. time frame as line could briefly clip those areas.
The exact track is still in question. It could even just clip Fulton County & that is it, or it could track a hair to the west. We will monitor very closely.
Tail end of derecho should pop some new storms in our area through morning to afternoon with risk of a couple to few severe gusts (SLIGHT RISK [Level 2] area will likely be expanded westward in future Storm Prediction Center outlooks for tomorrow mid-morning to afternoon).
Storms then move south & southwestward as they congeal into a line. Storms should be completely out out the viewing area by 6 p.m.
Friday looks dry & less humid with north to northeast winds & highs near 80 to the lower 80s. Skies look partly cloudy (but more cloudiness towards evening).
As for Saturday we look in-between severe weather from Missouri to western Kentucky with rainfall as far north as the I-70 corridor & broken line(s) of showers & storms from northeastern Iowa to Michigan.
We just look to have sun & clouds with southwest wind, but higher humidity compared to Friday with highs in the low to mid 80s.
We may pick up a few spotty showers & storms after 6:30-7 p.m. in the viewing area Saturday evening as one of those broken lines moves southward into the viewing area from the north.
A few spotty showers & storms are possible Sunday as cold front moves south & cold air aloft or shortwave follows. This will bubble clouds up to produce some rainfall with highs near 80 to the lower 80s. Dew points will be in the upper 50s to mid 60s.
Monday looks good overall with cumulus towers bubbling up & a couple isolated showers with highs upper 70s to lower 80s. Dew points will be in the upper 50s to around 60.
Tuesday & Wednesday should be dry with sun & highs 75-81 with lows 52-57 & dew points in the 40s & 50s daily.
Thursday looks good with sunshine & highs 80-84 with lows in the 50s & dew points in the comfortable 50s.
It may turn warmer with 83-88 Friday, but the humidity will be held in check with dew points 58-62.
