704 FXUS61 KRLX 251638 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1238 PM EDT Tue Jun 25 2024 .SYNOPSIS... Warmer today. Chance for showers and thunderstorms this afternoon and with a cold front Wednesday. Chances of showers and thunderstorms Saturday and Sunday with another cold front. && .NEAR TERM /THROUGH WEDNESDAY/... As of 1235 PM Tuesday... Convection from weakening MCS over the midwest this morning is moving into the area. So far much of this has remained sub severe, and bulk of any severe is still anticipated to remain to our west. Latest SPC outlook for day 1 still has just a few of our SE Ohio counties in a marginal, and this seems reasonable given latest trends. Otherwise, should be a bit of a lull in the activity later this evening and the first part of tonight, however, convection looks to reinvigorate overnight across the north out ahead of a cold front and passing shortwave. This should affect our northern zones late tonight/early Wednesday morning. Severe threat with this activity looks to be rather low at this point, but not a non zero risk, and heavy rain is expected. After the Wednesday morning activity, showers and storms will redevelop again during the afternoon and evening hours out ahead of an approaching mid level shortwave trough and the aforementioned cold front. Some of these storms could be strong to severe, with a damaging wind threat, possibly a small tornado threat also, and much of this activity looks to develop towards the end of the near term, and into the short term period. However, there still remains uncertainty as to any effects morning convection will play in the severity of afternoon storms. && .SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 225 AM Tuesday... A cold front and an upper level trough will bring showers and thunderstorms for Wednesday into Wednesday night. Models still differ on the handling of prefrontal energy and precipitation. This prefrontal convection could be critical to whether enough energy builds for severe weather. MesoNAM soundings showing many soundings with over 2000 effective layer CAPE with some dry air in the mid levels and freezing levels of 13000 to 13500. This indicates a good potential for damaging winds and large hail, if the prefrontal energy allows for sufficient heating. Some models indicate enough remaining moisture for scattered showers and thunderstorms in the mountains on Thursday, while others indicate a drier solution. Will keep some small mountain POPs, with a bit better chances in Virginia. More seasonable temperatures will return for Thursday. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 225 AM Tuesday... With a high pressure system shifting off to the east on Friday, temperatures will again climb back above normal for this time of year. A few mountain showers and thunderstorms are once again possible, although most of the region will remain dry. A southerly wind flow and an approaching cold front will increase the chances of showers and thunderstorms area wide on Saturday. Models have a cold front pushing through Saturday night or Sunday, with continued differences in timing between the models. More seasonable air can once again be expected on Monday behind the cold front. Once again, some models indicate enough remaining moisture for scattered showers and thunderstorms in the mountains on Monday, while others indicate a drier solution. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 630 AM Tuesday... Visible satellite showing river valley fog this morning, though most terminals remain unaffected, except for EKN which is reporting LIFR VIS/CIG. VFR takes back over after any fog dissipates under clear skies by ~12-13Z this morning. High pressure nearby keeps the area dry and mostly clear through the morning until at least early afternoon. There is a chance for some showers and storms this afternoon with a passing disturbance, but this looks to remain confined to southeastern Ohio until tonight into Wednesday morning. Any storms that form across SE Ohio could be strong to severe with damaging winds and small hail. PKB will to be the closest terminal to this activity, but should remain unaffected. Winds will be mostly calm this morning, picking up out of the southwest at a light pace after sunrise. Could be breezy at times mid-morning with mixing. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z WEDNESDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Showers and thunderstorms could be more numerous and cover more locations than advertised this afternoon.
