000 FXUS61 KRLX 161059 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 659 AM EDT Sat Mar 16 2024 .SYNOPSIS... High pressure takes control today. Weak cold front brings showers mainly across the northern portions of the area tonight. Much colder air moves in Monday with stronger front. && .NEAR TERM /THROUGH TONIGHT/... As of 417 AM Saturday... Added patchy dense fog along river valleys at both sides of the OH River as evident in satellite imagery during the overnight hours. Rest of forecast remains on track. As of 232 AM Saturday... Surface high pressure provides dry and tranquil weather conditions with above normal temperatures through tonight. A cold front approaches from the northwest tonight, increasing clouds and chances for precipitation mainly across the northern portions of the Mid-Ohio valley and WV tonight. Models show westerly H850 winds increasing 45 to 50 knots along the front. This will create strong gusty winds along the front and the higher elevations. However, confidence runs low whether wind gusts could reach advisory criteria over the higher ridges as only one model shows that outcome. Therefore, hold off on any wind headline issuance for now. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... As of 230 AM Saturday... Mostly zonal flow aloft with a broad upper low over Canada for Sunday. Dry conditions will commence late morning as showers lift off to the north behind a cold front. Westerly winds could be breezy at times; gusty across the mountains with gusts between 30 and 40 mph. An upper-level trough will swing through on Monday as the low over Canada moves off to the northeast. Breezy and gusty winds continue with a strong pressure gradient. 540MB line will also sink down as strong CAA takes place, and it will be noticeable with high temperatures in the 30s and 40s. At this time gusts look to remain below advisory criteria, but will have to monitor trends as there is a slight chance that gusts may increase depending on how this trough will track. There remains a slight chance for snow showers during the day Monday with this strong system. Accumulations do not look likely, except for along the ridges above 3,500 feet, as temperatures won`t be quite cold enough for accumulations. Up to an inch is possible across the higher elevations of the northern mountains. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 250 AM Saturday... Wind chills look to be in the teens and single digits across the higher elevations Tuesday morning with strong northwest flow continuing on the back side of the exiting trough. A clipper-type system will move through late Tuesday night into early Wednesday morning with another quick round of mountain snow possible. Temperatures will start to moderate Wednesday as flow tries to return to a more neutral pattern. Winds will gradually shift to a southeasterly direction on Thursday and Friday which lead to a warming trend throughout the week. A southern stream system looks to impact the weekend with rain returning Friday and Saturday. && .AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
