AREA FORECAST DISCUSSION National Weather Service Wilmington OH 532 AM EST Sun Dec 16 2018 .SYNOPSIS... Low pressure will track across eastern Kentucky into the mid Atlantic tonight into Sunday. A dry cold front will cross the region on Monday. High pressure will then build in through mid week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Broad mid level low over the Eastern Tennessee Valley this morning to translate east to a position off the Mid Atlantic coast by evening. Moisture wrapping around this low was resulting in continued clouds and some lingering rain. Elongated surface/925 mb lows over the Upper Ohio Valley, were resulting in continued lower level convergence and forcing over ILN/s eastern counties. This forcing will shift east with pcpn tapering off early. Can not rule out a few lingering showers even in the west early due to cyclonic flow and weak lift. Saturated near surface layer early today. Due to mixing in the boundary layer expect more in the way of low stratus than dense fog this morning. Flow becomes westerly and briefly anticyclonic this afternoon with clouds thinning out giving way to sunshine. Mild temperatures to continue with todays highs ranging from the upper 40s northwest to the lower 50s southeast. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... Northwest flow aloft with weak/subtle ridge dropping southeast through the area this evening. Shortwave to stay well to our northeast across the Great Lakes with weak sfc reflected trof to move through the area early Monday. Expect mainly clear conditions overnight with lows from the upper 20s northwest to the mid 30s southeast. Moisture and forcing to stay well north of the area Monday so expect dry conditions with only an increase in high level clouds. Expect mostly sunny conditions Monday with highs from the upper 30s northwest to the mid 40s southeast. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... Period begins with surface high pressure developing under a confluent northwest flow aloft. The anticyclonic circulation around the high will result in subsidence and dry weather conditions from Monday night through Wednesday. A transition to moist and unsettled weather is indicated starting on Thursday when surface low pressure is forecast to form ahead of a sharp upper trough. As the surface low travels up the Appalachians, an extensive plume of deep moisture will be advected on a strong southerly flow in advance of the low. While the low deepens below 1000mb on its path to Southeast Canada, expect showers and gusty winds Thursday through Friday. Residual precip will probably change to snow Friday night and Saturday as colder air filters in on a northerly flow behind the system. Temperatures staying near to above normal will be close to 40 on Tuesday, before climbing to around 50 by Thursday. Readings will retreat to the low and mid 40s Friday, then down to about 40 on Saturday. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... Low clouds circulating around a broad area of low pressure will slowly improve this morning as the low moves off to the east today. A few lingering rain showers or areas of drizzle will be possible early - especially across the northern TAF sites. Abundant low level moisture and a mixed boundary layer will lead to IFR to LIFR cigs through most of the morning, These ceilings will lift to MVFR prior to scattering out this aftn. Some MVFR vsby restrictions due to fog will improve early this morning. VFR conditions are expected this afternoon as drier air works in from the west. VFR conditions will continue though the night into Monday. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
