342 FXUS61 KRLX 251646 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1246 PM EDT Wed Jun 25 2025 .SYNOPSIS... The heat wave continues through the end of the week for much of the area, but eases up slightly as the chance for mainly afternoon and evening showers and thunderstorms increases. && .NEAR TERM /THROUGH FRIDAY/... As of 1207 PM Wednesday... Key Points: * Extreme Heat Warnings and Heat Advisories continue across the lowlands and southern and lower mountainous terrain for heat index values in the 100s this afternoon. * Heat Advisories are in effect across the lowlands for heat index values in the 100s Thursday afternoon. * Heat Advisories are in effect across the lowlands for heat index values in the 100s Friday afternoon. High pressure at the surface and aloft will continue to provide hot and humid weather conditions through the end of the week. Another warm and muggy night is on tap for tonight, providing little relief from the persistent heat. Heat advisories and warnings continue in effect for most of the area as heat index values meander around 103 this afternoon. Extreme Heat Warnings and Heat Advisories have been extended into Thursday evening for most parts of NE Kentucky, SE Ohio and much of the lowlands of West Virginia, as similar conditions are expected. Similar hot and humid conditions are anticipated on Friday, so another Heat Advisory has been issued for all of the lowlands until 8 PM Friday evening. With abundant low level moisture (PWATs around 2 inches), afternoon heat and a lack of deep layered shear or any other upper level support, isolated diurnal convection can be expected every afternoon and evening through Friday. Water loading soundings are indicative of strong downburst possible. WPC keeps a marginal risk for excessive rainfall at least for some portions of our area every day through Friday. Very warm and muggy nights will continue, with precipitation activity promoting chances for overnight fog development wherever they occur. Expect an increase in convective coverage each day as a frontal boundary approaches from the north. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/... As of 1207 PM Wednesday... Weather charts suggest the front will never make it south into our area. Instead, the frontal boundary lifts north over the weekend as the upper level high drifts east of the Appalachians by Friday night. This will allow for southern stream shortwave to lift north and provide some forcing under a moist and unstable environment. Therefore, the area will remain unsettled with additional afternoon showers and thunderstorms possible over the weekend. Very warm and muggy nights will continue, with precipitation activity promoting chances for overnight fog development wherever they occur. Temperatures will moderate some, due to cloudiness and afternoon cooling shower. && .LONG TERM /MONDAY THROUGH TUESDAY/... As of 1207 PM Wednesday... Better chances for showers and storms arrive Tuesday with a cold front. Dry weather returns by mid next week. Temperatures will moderate some behind the cold front by mid week. Central guidance keeps highs around 90 and lows around 70 across the lowlands into early next week, before both tail off toward normal heading into the middle of next week. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... As of 1235 PM Wednesday... Radar imagery shows afternoon convection firing up across portions of SE OH and northern WV at the time of writing. Expect this convection to expand in coverage through this evening as they move slowly east. Brief periods of IFR/LIFR visibility will be possible along the heavier showers or storms. Otherwise, VFR conditions will prevail under weak flow through at least midnight. Areas of IFR dense valley fog will be possible mainly over areas that receive rainfall this afternoon and evening. Any dense fog will quickly dissipate by 12Z Thursday morning. Surface flow will be calm to light and variable, beneath light, mainly northwest flow aloft. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z THURSDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Timing and impacts from thunderstorms may vary from forecast. Timing and extent of valley fog late tonight may vary, including the possibility of earlier, denser fog where thunderstorms occur this afternoon or this evening.
