The Storm prediction Center has placed the entire Tri-State under a "1" and a "2" on the Threat Index for Friday afternoon and early evening. Scattered rainfall will continue to gradually shift eastward from Northern Missouri and Southwestern Illinois late this evening and overnight. By daybreak, scattered showers will have already settled in over the Tri-State. Model data continues to suggest that scattered rain showers will linger across the Ohio Valley though the morning and early afternoon. Intensification isn't expected to occur until the leading edge of the advancing cold front reaches the Tri-State; that should occur between 12PM and 1PM early Friday afternoon.
As the cold front interacts with our mild and muggy air at the surface, it will produce a defined line of showers and thunderstorms, some of which may pack quite the punch. The latest projections indicate that this line should reach our westernmost communities before 1PM. The line of storms, capable of producing winds in excess of 50 mph and hail, will reach Evansville and Morganfield just before 3PM. From there the storms will continue on the eastward migration across the Tri-State pushing in over Madisonville, Owensboro and Tell City by 4PM. The last of the potentially strong to Severe storms will exit east of the region by 7PM. (All times are subject to change) That's great news for those of you who plan on attending a high school football game tomorrow evening; while there may still be a delay to kickoff in spots, the night shouldn't be a complete loss.
As the rainfall exits the Tri-State, so too will its corresponding cold front; that means that things are about to take a very fall-like turn along the Ohio! After seeing temperatures reach the mid to low 80s earlier on this afternoon and morning lows Friday near 70°, afternoon highs on Saturday will struggle to reach the mid 60s in spots. In fact, Saturday's anticipated high of 64° will mark our coolest day in over three weeks! Better yet, the combination of clear skies and a breezy northwesterly winds early Sunday will help drive the mercury to its lowest point in four and a half months! Evansville will dip all the way to 43° early Sunday morning - our coolest temperature since the morning of May 30th!
