AREA FORECAST DISCUSSION National Weather Service Charleston WV 236 PM EDT Thu Jul 29 2021

SYNOPSIS. Cold front arrives late this afternoon/evening, with severe thunderstorms possible. High pressure returns Saturday. Active weather returns for late in the weekend.

NEAR TERM /THROUGH FRIDAY/. As of 141 PM Thursday .

Abundant cloudiness accompanied by isolated thunderstorms associated with a decaying MCS crossing the area this afternoon. Isolated thunderstorms are evident on radar with this feature, but are expected to decrease in intensity as they enter to our area. A cold front will follow, crossing this evening and spreading additional showers and storms. Some storms could become severe.

The front moves into an favorable environment with MLCAPE values of 1500-2000 J/kg and deep layer shear of 40-45 knots. These ingredients will be enough to support super-cellular storm structures, and/or at least a broken line of convection racing south across the region through the late evening.

There is a slight risk for severe weather across the entire CWA, with the exception of our Va counties. The main concern with these storms will be damaging winds and the possibility of a tornado mainly across the north given high helicities there. Freezing level about 15,000 feet, will help to mitigate the occurrence of large hail per melting processes.

It still uncertain the convective mode along the cold front. Abundant cloudiness before and during sunset could limit the strength of storms. Otherwise, one or two supercells can develop, and/or a fast moving convective line to affect the area early tonight. Showers or storms will move quickly east with the cold front exiting the eastern mountains around 12Z Friday morning.

Lingering light showers will be possible behind the cold front Thursday morning. If skies manage to clear toward dawn, patchy fog will develop mainly along river valleys and areas that received rain and clear skies.

Very muggy conditions expected for the rest of tonight with temperatures and dewpoints staying in the upper 60s overnight. Friday promises near normal temperatures, generally in the mid 80s lowlands ranging into the mid 60s highest elevations.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/. As of 230 PM Thursday .

Showers aligned with the cold front will be departing our southern zones at the start of the period as the boundary aims for the Carolinas. High pressure will then hoist dry weather back into the area on Saturday with temperatures dipping below normal as cooler air filters in along northwest flow.

Precipitation chances ramp back up for the later half of the weekend in response to a series of shortwaves and eventual cold front progged to arrive late Sunday night into Monday. Greatest concentration in POPs appears to be across the southern half of the forecast area.

LONG TERM /MONDAY THROUGH THURSDAY/. As of 230 PM Thursday .

Longwave troughing to the east and dominating ridging to the west of the country will maintain a generally quiet weather pattern in the Central Appalachians heading into the work week. Surface high pressure reestablishes itself over the area on Monday, maintaining mostly dry conditions (particularly in the lower elevations) through midweek. Moisture sneaking up the mountains starting Tuesday afternoon may help spark diurnally driven showers and storms each day through the remainder of the period, perhaps sneaking into the Kanawha Valley after Thursday. Temperatures will gradually recover back toward their climatological normal for this time of year as the week progresses.

AVIATION /19Z THURSDAY THROUGH TUESDAY/. As of 141 PM Thursday .

Widespread VFR conditions will begin to deteriorate as a cold front moves over the area early tonight. Showers and thunderstorms are likely to develop along the front this evening. Periods of IFR/MVFR will be common along any convective element that crosses the area. Some storms could become severe with damaging winds being the main threat. Uncertainty is large whether any storm would affect directly any terminal. Therefore, coded wind gusts up to 28 knots, timing storms around 23-01Z affecting HTS, CRW and PKB, but severe storms could produce 60 knots winds.

These storms may contain brief periods of very heavy rainfall and associated IFR conditions. The front exits south and east of the Appalachians during the overnight hours.

Depending on the expected rainfall, skies clearing and near calm flow, areas of dense fog could develop for IFR/LIFR conditions overnight into early Friday morning.

Southwesterly winds gusting up to 17 knots will be common ahead of the front, turning northerly around 4KTs behind the cold front tonight. Gusty and erratic winds near convection.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z FRIDAY . FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing of afternoon/evening thunderstorms could vary by an hour or two. Fog coverage, intensity, and timing tonight could vary from the TAFS.
