It's a hot one out there. Afternoon highs reached into the low 90s across the Tri-State today, marking our hottest day in more than a week - worse yet, all of our humidity made those low 90s feel more like 100° at times today. All of that heat and humidity will also fuel some scattered shower and thunderstorm activity for the areas west and north of Evansville this evening. While the Storm Prediction Center has placed the northwestern quarter of the Tri-State under a "1" on the Threat Index our actually threat of Severe Weather will remain quite minimal this evening and overnight. That however, isn't expected to be the case come Friday.
Thursday's greatest threat for potentially Severe storms remains well to our northwest, primarily due to the presence of a slow moving cold front. This same cold front generated multiple Severe Thunderstorms and Tornadoes across portions of Iowa yesterday and will continue on its southeastward swing across the Midwest, reaching the Tri-State Friday. As I mentioned above, we already have our fair share of heat and humidity, so the thunderstorm fuel is present - all we need is a match and that will come in the form of Friday's passing cold front. Ahead of the storms' arrival, the Storm Prediction Center has placed the entirety of the Tri-State under a "1" on the Threat Index; the primary threat from tomorrow's storms will be damaging straight-line winds in excess of 60 mph.
Following some initial rainfall north and west of Evansville, the latest model data suggests that the first of what will develop into our potentially strong to Severe storms should form between 12PM and 1PM Friday. We'll continue to see showers and storms fire up ahead of the advancing cold front though the rest of the afternoon and into the evening; the threat for Severe Weather will likely linger though 8PM or 9PM. While our Severe Weather threat may subside late tomorrow, our rain chances will not; showers and thunderstorms may continue to roll across the region into the predawn hours Saturday. Unfortunately, it also looks like sporadic showers and storms may continue to affect the Ohio Valley though our Saturday and Sunday as well.
