DISCUSSION
Issued at 140 AM EDT Mon Jun 15 2026
Storms have moved out of the region but lingering showers mainly in the northern half of the region will continue late tonight dissipating by early morning. Currently the cold front appears to be near the Virginia/Kentucky border stretching through the Cumberland Plateau. This front will move through the region by morning and stall well to the south today and tomorrow. In the upper levels, the broad trough over the Central and Eastern U.S. will deepen today. Today and Tuesday will be dry and much cooler with highs mainly in the lower 80s.
By Wednesday, temperatures start to rebound with nearly zonal flow aloft and southerly flow at the surface. Very low rain chances start to creep back into the region on Wednesday but remain around 15% or less.
Rain chances are high Thursday into Friday. A system will move through the Great Lakes region on Thursday bringing a shortwave through the Ohio Valley and a slow moving cold front into the Ohio Valley. At the same time, a Gulf low near LA/TX will move through the Southeast. There is some timing discrepancies in the models but between the cold front and this Gulf Low rain chances are high from Thursday through Friday afternoon. The Gulf system is expected to move out and the cold front finally move through the region around Friday evening. Saturday looks dry and slightly cooler with troughing and high pressure.
AVIATION
(06Z TAFS) Issued at 140 AM EDT Mon Jun 15 2026
Guidance and satellite disagree on extent of MVFR CIGs currently. Went halfway between the two with TEMPOs at KTYS and KTRI for the most likely timeframe. Otherwise, dry weather with light winds expected through the TAF with primarily predominant VFR conditions expected.
