AREA FORECAST DISCUSSION National Weather Service Charleston WV 745 PM EDT Wed Aug 5 2020

SYNOPSIS. High pressure sails north of the area this afternoon through Friday, while a series of disturbances move up the Appalachians. A warm weekend is expected with minimal precipitation chances.

NEAR TERM /THROUGH THURSDAY/. As of 745 PM Wednesday .

Freshened up POPs and sky conditions to remain on track with current trends.

As of 233 PM Wednesday .

Surface high pressure will prevail with mostly fair weather conditions through the period. Some showers or storms could develop along the eastern mountains this afternoon and evening, but they should be weak. Decrease rainfall activity tonight. River valley fog is expected to develop once again overnight tonight mainly at EKN, CRW and BKW during the predawn hours. Any fog will dissipate by 730 am.

Shower activity could increase Thursday afternoon with an upper level shortwave passage. The bulk of the convection should occur along the higher elevations, spreading west into central WV.

Central guidance reflects near normal temperatures on balance.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/. As of 205 PM Wednesday .

Upper level troughing lingers over the area Thursday night into Friday before shifting east out of the region late Friday afternoon. Will largely be a race between surface heating and the best vorticity advection exiting east through early afternoon with regards to any potential shower and thunderstorm formation late morning into the early afternoon. Based on current guidance, not expecting much activity on our side of the mountains, but should the trough exit a bit slower could see a little activity near our eastern fringes with some updraft organization possible in the presence of stronger mid-level flow.

LONG TERM /SATURDAY THROUGH WEDNESDAY/. As of 205 PM Wednesday .

Broad ridging over the southern US amplifies for the weekend with building heights and a return to above normal temperatures with highs across much of the Lowlands in the upper 80s to to near 90 for the weekend. Subsidence will keep Saturday mainly dry aside from a slight chance of afternoon showers in the mountains with increasing chances for Sunday afternoon as ridging begins to break down in advance of the next approaching wave. Monday looks to be the warmest day of the week with a marginal uptick in southwesterly flow in response to the aforementioned wave moves through the Upper Great Lakes. As the disturbance exits northeast across the Canadian Maritimes Tuesday, we'll fall under in the influence of a slow moving cold front dropping in from the north presenting a better focus for showers and storms for Tuesday and Wednesday. Given weak flow, 90th percentile precipitable water values (1.5+ inches), and ample instability, the main threat with this activity will be slow moving thunderstorms producing locally heavy rain.

Changes over central guidance focused mainly on diurnal timing of convection.

AVIATION /00Z THURSDAY THROUGH MONDAY/. As of 745 PM Wednesday .

The period starts off with blanket VFR conditions across the region beneath surface high pressure. River valley fog encroaches on the usual vulnerable terminals during the predawn hours Thursday, resulting in IFR or worse visibilities before quickly eroding after sunrise. Showers and storms will prosper along the higher terrain Thursday afternoon in a similar fashion to what was observed today. Opted for VCTS for BKW during the afternoon in the event a storm develops in close quarters to the aerodrome.

Winds will remain light and variable through the TAF period.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z FRIDAY . FORECAST CONFIDENCE: Medium to high.

ALTERNATE SCENARIOS: Timing and intensity of fog may vary from the forecast early Thursday morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
