EVANSVILLE, IN (WFIE) - Most of the Tri-State saw around a third of an inch all the way up to an inch of rain in early thunderstorms on Thursday. More rain is likely overnight Thursday into Friday morning. Skies were clearing over southern Illinois on Thursday afternoon, and the additional heating will give a boost to storm development later Thursday night. Widespread severe storms are not expected, but a few may produce hail and wind in addition to locally heavy rainfall. The next round of storms will move in around 2am across the Tristate:
We’ll catch a break in the rain on Friday, but it will only be temporary. Skies will be partly to mostly cloudy during the day with highs near 70. The atmosphere will remain moist and a cold front will be stalled out near the Ohio River, so there will be a mechanism to kick off more storms when the front wiggles back to the north:
Showers and storms are likely early Saturday and again in the afternoon. Notice Louisville on Saturday...odds are good for a wet Kentucky Derby again. In 144 Kentucky Derbies, it has rained at some point during the day 47% of the time. In the last 20 years, track conditions were muddy or sloppy 6 times.
Overall severe weather risk will remain low to non-existant. A few storms may drop some brief heavy rain during the period.
Rainfall forecasts have been a bit overdone, but a soggy start to May would accurately describe the first 4 days of the month. Sunshine and mid 70′s return on Sunday.
