Conditions are expected to remain breezy, mild and primarily dry through the overnight hours and early tomorrow morning. After seeing our second straight day of 70° temperatures, we'll dive back into the mid 50s area-wide; we'll fall to 56° in Evansville during the predawn hours tomorrow. While we'll kick off our Wednesday under scattered cloud cover, gradually decreasing clouds and a strong southwesterly wind (gusting near 30 mph) will help drive temperatures to their highest point in over four and a half months - it's expected to be 73° in the River City Wednesday, our warmest temperature since November 10th.
The mild, windy conditions are expected to linger for our Thursday ahead, though a core of low pressure tracking northeastward from the south-central Mississippi Valley will produce scattered shower and thunderstorm activity throughout that day. In fact, the Storm Prediction Center of America has placed the entirety of the Tri-State under a "1" or a "2" on the Threat Index for that evening. The current model data suggests that a well-defined line of storms will reach the Tri-State shortly after dinnertime that night and progress northeastward across the Ohio Valley before exiting east of the region just before midnight.
The anticipated timeline for Thursday Severe Weather Event will begin at 7PM and conclude at 12AM Friday. During that five our stretch, storms impacting the Tri-State may produce damaging straight-line winds in excess of 60 mph, quarter-sized hail and periods of tight rotation that may result in brief tornadoes. After the last of the potentially Severe Storms exit the Tri-State, conditions will calm and set us up for a more pleasant, albeit cooler, Friday ahead. Expect a high that day near 63° under mostly sunny skies as we wrap up the work week.
