We saw one broken line of storms & then a highly-broken line of showers & t’storms in the evening-lastnight, but all wind/hail reports were either northeast of southwest of the Tri-State.
Today & tomorrow, any severe weather will stay southwest & south of our area & we will stay on the cold, raw north side of the front & storm system.
This cool weather will carry us through the weekend, but be replaced by summer-like weather mid- to late-next week.
This cool period usually occurs in two periods of spring: When the Flowering Dogwoods bloom & when the Black Locusts bloom. Such cool periods follow stretches of warmth that prompt these tree species into peak blossom. So, usually the chills are noted for being extra colorful!
Blackberry Winter occurs when the blackberries are at peak blossom & we usually see our last 40s/50 of the spring before the summer heat sets in for good.

Periods of rain with isolated t’storm or two will occur today & into tonight with the heaviest rainfall overall for the Tri-State will likely occur between 3 a.m. & 11 a.m. Local flash flooding & considerable ponding on roadways & in fields is likely during that period. Embedded t’storms will occur in this mass of heavy rain. In additions, winds will be gusty from the northeast, driving that rain. Gusts of up to 35 mph are possible.
There may be a 1-2 hour slight lull Saturday afternoon with just misty, nasty cold, wind-driven drizzle, followed by rain through mid-afternoon & into tomorrow night with strong northeast winds turning to the north with 35 mph gusts.
Any lingering showers will exit Sunday morning, followed by a clearing trend, but it will still be a rather cool, windy day with north winds gusting to 35 mph.
Taking the rain we have already received today & adding what we are expected to get the rest of today, tonight, tomorrow to Sunday morning, 1-3″ is likely area-wide.
The lowest totals will generally occur in the north with 1″, while the 2-3″ totals will tend to occur south of the Ohio River. Looks like a 1.50-2″ rainfall possible for the Evansville area.
Temperatures look chilly with 50s to lower 60s today, 40s & 50s tonight & 50-55 tomorrow, followed by 40s tomorrow night, 50s & 60s Sunday & 37-44 Sunday night!
Dry, breezy to windy & very warm weather will arrive next week, which will allow fields to dry out quickly for farm work to resume. Boy is the corn going to grow with the warmth ahead next week!
Potential of some severe weather may return by either next Friday or next weekend.
A significant spring storm that may dump impressive snowfall amounts in the Rockies to High Plains will likely bring multiple rounds of severe weather with flooding rainfall to the Plains from Minnesota to Texas. The system may be blocked by large upper ridge in the eastern U.S. with our warmth, so it may be a daily severe weather event/outbreak scenario Wednesday-Friday for the Plains with training severe t’storms.
We may see some severe weather by next weekend as the large upper trough migrates eastward & northeastward. However, highs may reach 85-90 by next Friday/Saturday.
