000 FXUS61 KRLX 262002 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 402 PM EDT MON SEP 26 2016 .SYNOPSIS... A cold front is crossing the area providing showers and thunderstorms. A large upper level low drops into the area Wednesday and Wednesday night, and then swirls about the area Thursday through Friday. && .NEAR TERM /THROUGH TUESDAY/... As of 400 PM Monday... A cold front is currently moving through the area though most thunderstorms have already occurred in the pre-frontal band which is nearing our eastern cwa boundary. Expect a gradual decrease in shower activity tonight as front pushes through with an associated temperature and dew point drop. Clearing skies, light winds, and residual moisture should make conditions ripe for a night of dense fog which should last into the late morning. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 310 PM Monday... Some seasonable Fall weather is finally on tap for the region. A Broad upper low/trough will dig south across the region and remain nearly stationary overhead. We will be mostly clear Tuesday night and will have a cool start to the day on lows drop into the 40s just about everywhere. The cool weather will remain through the end of the week as H500 anomaly of 2 to 3 standard deviations below normal expected with upper low. As the upper low pushes in we can also expect an increase in shower activity with cooling temps aloft and continued height falls on Thursday. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 320 PM Monday... Operational and ensemble guidance is in pretty good agreement with large upper level low remaining overhead well into the weekend. With the cool temperatures aloft...any daytime heating we receive will quickly yield showers and possible isolated thunderstorms. The good news is that this should bring some much needed rainfall to the region and amounts will remain light enough so we are not expecting any hydro issues. The upper low meanders northward Sunday into Monday with ridging moving in behind it. This will bring warm air back into the region with upper 70s to near 80 degrees for the start of the next work week. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... As of 400 PM Monday... Cold front moving through bringing isolated MVFR/IFR conditions otherwise VFR. Winds lull tonight setting up a favorable environment for LIFR fog, so will be trending forecast that way. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing and extent of stratus and fog behind the front tonight may vary.
