000 FXUS61 KRLX 260311 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 1011 PM EST Sat Feb 25 2017 .SYNOPSIS... Turning colder for the rest of this weekend. Warmer with upper level disturbances and rain showers next week. && .NEAR TERM /THROUGH SUNDAY/... As of 1010 PM Saturday... Forecast in good shape this evening. No changes needed attm. As of 645 PM Saturday... Inserted scattered flurries across the northern half of the CWA for this evening...transitioning to snow showers in the northern mountains where an inch may accumulate overnight in the higher elevations. Timed the exodus of stratocu based on WAA timing in the low levels. This allows southern areas to see clearing tonight with the remainder of the area clearing out rapidly Sunday morning from southwest to northeast. Winds will very gradually diminish in the lowlands tonight but still remaining quite gusty in the mountains...with some highest ridges likely gusting above 40 kts at times. As of 115 PM Saturday... Cold front will continue to move east and out of the area late this afternoon. Rain showers will exit as well. Much colder air is on tap for tonight and tomorrow with temperatures dipping into the 20s over much of the area...with some teens in the colder valleys of the northern mountains. H500 trof will swing through tonight. This will keep the chance for snow showers or flurries with brisk WNW winds in the forecast for upslope areas of our eastern mountains overnight tonight. High pressure quickly builds over the area tomorrow bringing plenty of sunshine, but much cooler temperatures. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... As of 235 PM Saturday... High confidence in the first half of the short term forecast with cool and dry high pressure centered over the region. Clouds will be on the increase on Monday as a warm front lifts northward through West Virginia. During the day Monday we should remain mostly dry. Model guidance is spitting out some light QPF for Monday, however low levels are quite dry and QPF may be a bit overdone. Current thinking is that we may see a few sprinkles and VIRGA during the day and for now I decided to just go with slight chance to low chance PoP in the forecast. With the cloud cover, we will see low temps much warmer Monday night as most areas should remain in the low 40s. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... As of 240 PM Saturday... Not much changes from the previous forecast. Very warm conditions once again for the area as we head into the middle of the week under deep southwesterly flow. However, flow amplifies with deep upper trough starting to dig over the Central U.S. late Wednesday and progressing east through the remainder of the period. Guidance shows intense low pressure tracking across the Great Lakes and driving a strong cold front across the area Thursday. This will continue our roller coaster weather as temperatures turn much colder for the end of the work week with possibly some snow on tap for next Friday. && .AVIATION /03Z SUNDAY THROUGH THURSDAY/... As of 650 PM Saturday... CAA stratocu will continue to overspread the area this evening. Thinking northern TAF sites will see MVFR cigs at times with southern sites staying low end VFR. There will also be flurries flying this evening over the northern sites with vsby dips into MVFR possible for CKB/EKN tonight. The stratocu will erode from southwest to northeast Sunday morning with a mainly sunny sky by midday. Westerly Winds will gradually diminish for CRW/HTS tonight...but remain gusty for northern sites and BKW. Expect winds to diminish here on Sunday as high pressure builds into the region. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY... FORECAST CONFIDENCE: Medium to high. ALTERNATE SCENARIOS: EKN/CKB could briefly dip into IFR vsby should any robust snow showers affect those sites tonight.
