000 FXUS61 KRLX 131751 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 151 PM EDT Sat Apr 13 2024 .SYNOPSIS... Flooding becomes increasingly confined to the Ohio and backwaters today. Breezy/dry today with dry weather continuing through Sunday morning. A weak cold front Sunday night. && .NEAR TERM /THROUGH SUNDAY/... As of 1225 PM Saturday... High pressure in control across the area, with dry air in place. This has allowed for a quick warm up in temperatures across the area today. Tonight, expect rather mild conditions, with slightly warmer temperatures on ridge tops where higher winds will exist, but winds should increase area wide towards morning. On Sunday, there could be a brief shower or just some sprinkles early in the day as a warm front pushes east, along with increasing gusty winds as the day progresses and pressure gradient tightens across the area. Otherwise, later Sunday, a weak cold front will push south towards the CWA late in the period, ending up in northern SE Ohio zones towards the end or after the end of the near term period. Showers and storms are possible as it does so, but overall, looks to be rather isolated in nature for the near term period. There is a marginal risk for severe across northern zones, and greatest threat area looks to be mostly confined to SE Ohio zones where better instability/more favorable timing will exist. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... As of 220 AM Saturday... Dry weather can be expected Sunday morning. Above normal temperatures Sunday afternoon will aid in developing showers and thunderstorms later Sunday in advance of a weak cold front. This front will push into the region Sunday night, before stalling over southern portions of the area and becoming moisture starved on Monday. Even so, there is a small chance of showers and thunderstorms along and south of the front over southern West Virginia, Kentucky, and southwest Virginia. North of the front, slightly cooler temperatures can be expect across southeast Ohio and northern West Virginia on Monday as compared to Sunday. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 145 PM Saturday... A stalled front returns northward as a warm front on Tuesday, providing for a chance of showers and thunderstorms. This is not an exceptionally moist warm front for spring, with PW values of around an inch actually supported by saturation near and above h7. Very narrow elevated CAPE and modest shear can support showers and even thunderstorms, but precipitation will be light, and even any thunderstorm should not be particularly strong no heavy. Tuesday night will find the area in the warm sector of a low pressure system crossing the midwest. While an initial band of showers and thunderstorms may arrive toward dawn, showers and thunderstorms are more likely Wednesday afternoon and evening, as the low crosses the Great Lakes and drags its cold front into the area. Better moisture and instability is depicted ahead of the cold front Wednesday afternoon, with PW values of around 1.25 inches and 500-1000 J/kg CAPE. With favored late day or evening timing, strong heavy thunderstorms are a possibility Wednesday. The weather should dry out Wednesday night on loss of heating and the passage of the cold front, but timing of precipitation the balance of the week will depend upon the timing of another cold front, and possible wave. The front will initially have little moisture to work with as it comes on the heels of its predecessor, but if a wave forms along it, it may be able to garner more moisture. The frontal timing appears vary from late Thursday through Friday with the wave then riding right up along it, but the wave could then carry the chance for rain into the start of next weekend. The warm front takes temperatures well above normal Tuesday through Wednesday, before the successive cold fronts then take temperatures back toward normal during the latter portion of the upcoming week. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/...
