&& .NEAR TERM /THROUGH SUNDAY/... As of 100 PM Saturday... The next area of rain currently moving into the area. Thankfully most places have warmed above freezing...thus the freezing rain advisory has been cancelled. This final impulse will move out tonight with the old frontal boundary riding its coat tails out of here. In its wake drier and colder air will be trying its hardest to advect south into the area late tonight. This should allow the low stratus to scatter out across portions of southeast OH and northern WV which could result in dense fog or freezing fog forming along with some black ice as surface temps fall into the 20s. Will pass along concern to evening shift for perhaps an SPS to address this. Elsewhere...a period of drizzle will be realized after the system departs with low stratus and fog hanging tough into the morning hours. This will gradually break up as the day progresses on Sunday with some sunshine being realized across the north. This will be temporary as mid and high clouds build in from the west ahead of the next isentropic lift system. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... As of 200 PM Saturday... The front that has been waffling around the area will lift northward as a warm front Sunday night and Monday. Some models indicating that freezing rain is a possibility Monday morning. Will have to monitor this situation closely. An approaching weak cold front will then bring chances of showers Tuesday, with the front pushing through Tuesday night. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 200 PM Saturday... Cooler air will move in behind a cold front on Wednesday. Models then have considerable differences for the end of the week and into the weekend, although agreeing on unseasonably warm weather. Therefore, forecast confidence in precipitation is low during this period. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/...

00Z Sunday thru 00Z Monday... As of 640 PM Saturday... Band of rain with weak front will drop south overnight, exiting the southern most areas by Sunday morning. However, very light north winds and lingering low level moisture with even some drizzle will keep IFR or LIFR until drier air works in from the north beginning after 06Z. Thus, PKB and CKB will improve to MVFR 09Z-12Z, while remainder of TAFS continue IFR or LIFR. After 12Z drier air will continue to work slowly south, further improving conditions from north to south. Expect VFR at PKB CKB and EKN, MVFR at HTS and CRW, but continue IFR at BKW by 16Z. Thereafter, not too much change with MVFR holding central sections including HTS and CRW, but reaching BKW during the afternoon, while IFR holds far south. Winds will remain north to northeast for the most part 3-7 KTS. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY... FORECAST CONFIDENCE: LOw to Medium. ALTERNATE SCENARIOS: Timing improving conditions thru the period may vary several hours. Dense fog may additionally form later tonight in the north if clouds break earlier.
