675 FXUS61 KRLX 031530 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1130 AM EDT Fri May 3 2024 .SYNOPSIS... An approaching cold front brings showers and storms this afternoon into the weekend. Active weather continues into next week with daily chances for showers and storms. && .NEAR TERM /THROUGH SATURDAY/... As of 1123 AM Friday... Satellite and radar imagery show clouds and showers moving slowly east northeast across the Mid OH valley and portions of WV late this afternoon. Expect this activity to increase in intensity and coverage this afternoon and evening. Previous forecast remains on track. As of 640 AM Friday... Freshened up PoPs to account for isolated showers that are encroaching upon the western fringe of the CWA earlier than anticipated. No other changes have been made at this time. As of 220 AM Friday... Moisture starts to increase this morning as high pressure fades to the east and a cold front approaches from the west. Warm air, transported into the area by southwesterly ahead of the front, should allow temperatures to rise into the 70s to 80s during the day. Showers will begin spreading across the area this afternoon, with scattered thunderstorms also likely to sprout up as moderate instability develops within the warm and moist environment. The frontal boundary then loiters to the west while a shortwave lifts across the region and sustains shower and storm activity within the CWA overnight. Precipitable water is expected to rise throughout the day, with values ranging from 1 to 1.75 inches this afternoon into tonight. This signals potential for some heavier downpours which could create localized problems mainly for poor drainage areas; however, widespread flooding is not anticipated given the fairly dry conditions leading up to today. Tonight`s temperatures are expected to be mild, with lows in the 50s to 60s. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
-- Changed Discussion --
As of 1128 AM Friday... More of the same type of weather is expected Sunday with a stalled front nearby bringing scattered showers and thunderstorms. Weak flow aloft and weak shear of only 15-25 kts should mitigate the risk of severe weather. Localized flooding remains possible, especially in areas that previously saw heavier downpours over the previous few days. Expect high temperatures in the lower 80s across the lowlands and the 70s in the mountains. The air will feel slightly humid across the lowlands with dew point temperatures ranging from 60-65 degrees.

&& .LONG TERM /MONDAY THROUGH THURSDAY/...
-- Changed Discussion --
As of 1129 AM Friday... The unsettled pattern will continue into the new work week with chances of scattered showers and thunderstorms on Monday and Tuesday. Some models are showing the potential for severe weather Wednesday with 35+ kts of 0-6 km bulk shear and 1,000-2,000 J/kg of MLCAPE in spots. Confidence is low at this time, but this will be something to monitor over the coming days. Our region will be positioned in the warm sector with dew points 65-70 degrees and PWATs around 1.5 inches, so localized flooding might also be a concern Wednesday. In addition, we will also have to watch for the potential of gusty non-thunderstorm winds with low pressure strengthening over the Great Lakes. Our region will remain in the warm sector Thursday, and it still looks very warm and humid with chances of showers and thunderstorms. Next Friday remains uncertain, but some models are showing a warm front sinking south of the region with slightly cooler weather returning.

As of 640 AM Friday... Early morning fog will dissipate early in the TAF period, then showers and thunderstorms that are currently approaching from the west are expected to spread across the area as a front nears during the day. Activity should then be sustained into tonight due to a passing disturbance. VFR ceilings are expected to gradually descend to low-end VFR as the day progresses and then further degrade to MVFR/IFR overnight. Periodic restrictions to visibility will also be possible within any heavier showers or storms later today and tonight. 5-10kt southwest winds are expected much of the day, followed by light and variable winds for tonight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Onset time of precipitation may vary from the forecast.
