Area forecast discussion, Oct 20, 1:43 PM EDT, 1 hour 4 minutes before
Area Forecast Discussion National Weather Service Charleston WV 143 PM EDT Thu Oct 20 2016 .SYNOPSIS... Cold front moves from west to east this evening into tonight with showers and storms. Precipitation lingers Friday, possibly Saturday. Moisture starved cold front Sunday Night. && .NEAR TERM /THROUGH FRIDAY/... As of 130 PM Thursday... Surface boundary beginning to move again after being stalled across Central Ohio for most of the morning. This is due to a surface low making its way into Central Kentucky early this afternoon. West of this front, have dense cloud cover and fairly widespread rain. East of the front, a cumulus deck has been developing along with scattered showers and thunderstorms. Thus, the main feature to track through the tonight is the boundary as it slides east. This afternoon, with most of the CWA ahead of the front, we will see showers and thunderstorms moving through. Used a blend of near term, hi-res guidance to formulate POPs...with an area of likely POPs crossing CWA through this evening. Clouds have limited instability some, but combined with decent shear we should still have enough instability to drive some stronger cells capable of gusty winds. Still not real excited about these reaching severe limits, but cannot rule out and isolated bowing segment with damaging winds threat. Tonight, as the front continues east, we will se more widespread precipitation and clouds quickly lowering. Have large area of 100 POPs just behind the front, lingering into the early morning hours. In general, looking at a 1-2" rainfall event providing some relief to the parched ground. Expect a slow recovery on Friday, with low stratus and light rain/drizzle/fog lingering through much of the morning. This will limit diurnal heating, so have fairly flat temps -- and even non-diurnal at higher elevations of the northern mountains as 850mb temps continue to fall through the day. Afternoon highs will be significantly cooler than today, with most locations staying in the 50s. && .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/... As of 245 AM Thursday... For Friday night into Saturday, lingering low level moisture and a northwest wind flow may continue to squeeze out some light rain or drizzle...more likely in the mountains. Any remaining precipitation should end late Saturday as cold air advection shuts off. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... As of 245 AM Thursday... Models show a moisture starved reinforcing front moving through late Sunday or early Monday. Considerable differences between the models with this feature. Will keep some slight chance pops. High pressure then builds in and remains into mid week. Another cold front approaches later in the week. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... As of 140 PM Thursday... Messy TAF period ahead as a cold front moves through the forecast area. Ahead of the cold front, have a VFR cumulus deck forming with some showers and thunderstorms expected. Did include some MVFR tempos in thunderstorms, using HRRR for timing. Could even get brief IFR. As the cold front passes tonight, more widespread rain is expected as well as a low stratus deck moving in. This leads to IFR to LIFR conditions once the front passes...lingering well into Friday morning. Winds are generally southwesterly this afternoon outside of any thunderstorms, and will shift to northwesterly behind the front. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z FRIDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: IFR possible in thunderstorms into tonight. Timing of frontal passage and drop into IFR rain/stratus may very...as well as timing of recovery Friday.
