We finally get a break from the relentless pattern of storms and flash flooding! The final round of convection dissipated over the Evansville Tri-state region early this morning. Areal Flood Warnings remain in place for a few areas due to water remaining over numerous roads. The upper level ridge centered across the Deep South is in the process of shifting north resulting in a very hot and steamy afternoon across our area. Afternoon heat indices at 1 PM have already reached the upper 90s to low 100s.

A 594-597dm ridge will build into the Quad State region Monday into Tuesday and then become more centered just east of our area in the Ohio Valley Wednesday into Thursday. This will result in our first extended heatwave of the season (Paducah has only had 2 days reach 90 to this point in the season). Daily highs reach the low to mid 90s, coupled with dewpoints in the mid to upper 70s, which will produce heat index readings peaking from 105 to 110 in many places each day. Went ahead and issued an Extreme Heat Warning with this package given the duration aspect (4 straight days with 105+ heat index). There will also be limited relief at night with lows only falling into the mid 70s.

As the ridge center shifts just east of us there is some hint at convection trying to work north into part of west KY as early as Wednesday afternoon. Can't rule this out, but it appears a bit more likely for isolated convection on Thursday. The ridge begins to break down Friday into the weekend, which may allow a more typical summer-time airmass to reside across our area over the 4th of July holiday weekend. Plenty of instability and moisture in place to support at least isolated to widely scattered convection each day, although there doesn't appear to be much in the way of upper level support (shortwave energy) until at least Sunday or early the following week. Just appears like what you'd typically have in July with highs in the low 90s along with high humidity producing heat index readings in the low 100s which provides fuel for some afternoon/early evening convection.

SCT-BKN cu field will gradually erode by late afternoon. Initially have some MVFR bases but those should rise to VFR levels by mid afternoon. Southwest winds around 8-10 kts this afternoon will become light overnight. Will likely see SCT cu develop again by late morning Monday.
