000 FXUS61 KILN 172337 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 737 PM EDT Sat Mar 17 2018 .SYNOPSIS... High pressure will begin to build into the region tonight. It will provide dry weather Sunday and Sunday night, before another area of low pressure brings precipitation to the region Monday into Wednesday. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Very light precipitation north of I-70 will diminish as it sags east southeast this evening. Convection across Kentucky looks like it will pass just south of the forecast area. Clearing across northern Ohio and Indiana will progress south through the night. Adjusted temperatures to keep them a bit higher while clouds remain, but forecast lows still look reasonable. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... High pressure will provide sunny skies for Sunday. Abundant solar insolation will actually allow temperature to push a few degrees above normal, topping out in the lower to mid 50s. The region will remain dry Sunday night, as the high pressure center moves to the east and the next low pressure system begins to develop in the plains. A few high clouds should start to affect the region. Lows will be warmer ranging from the lower 30s in the north to the upper 30s south. && .LONG TERM /MONDAY THROUGH SATURDAY/... An upper level disturbance will approach the area at the start of the long term period. Precipitation will start out in the form of rain, however as colder air begins to work into the region Monday night precipitation will begin to changeover to snow. There is the potential for an axis of some accumulating snow Monday night. There are still some model differences with this however and therefore have decided to leave out of the HWO at this time. While precipitation may decrease some during the day on Tuesday another upper level disturbance and surface low approach the region from the south and therefore additional precipitation is expected Tuesday night into Wednesday. Went cooler than the blends on Wednesday with northerly flow. Due to this expect additional potential for accumulating snow Tuesday night into Wednesday. Dry conditions will then move into the region Wednesday night into Friday. Another system moves into the region for the weekend. Went lower than the blends again for temperatures across the north on Saturday due to cool easterly flow with precipitation and cloud cover. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... MVFR ceilings from KCVG/KLUK to KILN will lift to VFR early in the TAF period. Cloud deck across the entire region will clear from north to south overnight. Skies will be clear through the rest of the period. Northeast winds will diminish overnight. As high pressure builds in winds will become light and variable. These may come around to southwest late in the period. OUTLOOK...MVFR ceilings and visibilities are possible from Monday night through Wednesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None.
