AREA FORECAST DISCUSSION National Weather Service Charleston WV 631 PM EST Thu Feb 20 2020

SYNOPSIS. Low pressure heads east off SE US Coast tonight. Strong high pressure dominates Friday through the weekend, which starts cold and then moderates. Low pressure Monday and again midweek.

NEAR TERM /THROUGH FRIDAY/. As of 1230 PM Thursday .

Light snow ongoing across the extreme southeastern edge of the forecast area. Blended recent hires guidance into POPs, tightening up the gradient on the NW side of the storm heading off the Southeast Coast. This blend kept likely POPs close to where the previous forecast had them, but cut them back much faster heading north and west. Still have max snow accumulations of 1-2 inches along the ridges in SE VA and extreme S WV.

Any lingering snow will quickly come to an end this evening as the low pressure system continues moving east over the Atlantic Ocean. Clouds will follow suit, with the sky clearing out overnight. With dry low levels, expect a decent radiational cooling night. Used a blend of the ECMWF and consensus MOS for lows, with is on the lower side of the guidance envelope for lows. Friday will be another cool day, with highs generally in the 30s.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/. As of 225 PM Thursday .

Sunny Weekend On Tap .

Sprawling high pressure over the southeast states will make for a spectacular weekend given the abundance of cloud filled days over the past several weeks. I continue to undercut NBM considerably in the valleys and hollows for overnight lows given ideal radiational cooling expected. The cold mornings will give way to seasonable afternoons, making for large diurnal spreads in this very dry airmass.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 230 PM Thursday .

Our stretch of nice weather will come to an end next week with at least two systems slated to impact the region. The first may briefly start as a mix or wet snow early Monday morning before transitioning to rain as low pressure tracks near or west of the area. CAA will follow the departure of this system Tuesday with lingering light rain changing to some wet snow in the mountains.

A more impressive system is forecast for mid to late week as a highly amplified upper trof pivots into the OH Valley. Depending on how the dynamics unfold, this may be more of wintry system for us, especially in the mountains.

AVIATION /00Z THURSDAY THROUGH TUESDAY/. As of 630 PM Thursday .

VFR conditions are expected to persist through the period. Cloud ceilings should raise throughout the period and clear out by Friday morning for most sites, with some of the more eastern sites clearing out later in the period around Friday afternoon to evening. There is a possibility that BKW and EKN may see some MVFR ceilings in the next few hours, but the ceilings should start to lift back up by Friday morning.

Winds will be north-northwesterly at around 5-10KTs throughout most of the period. HTS and CRW may possibly see gusts up to around 15KTs within the first few hours of the period.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z SATURDAY . FORECAST CONFIDENCE: High.

ALTERNATE SCENARIOS: Possible MVFR ceilings at BKW and EKN at the beginning of the period.

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.
