AREA FORECAST DISCUSSION National Weather Service Wakefield VA 426 PM EDT Fri Sep 18 2020

SYNOPSIS. Strong high pressure will build into the region from the north northeast Saturday through Sunday. This high will stay over the region through much of next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 300 PM EDT Friday .

A few light showers/sprinkles continue across SE VA and NE NC due to onshore flow and weak low level convergence between the offshore low and the Canadian high building in from the west. Expect these showers/sprinkles, along with mostly cloudy skies, to continue tonight close to the coast due to continued low level moisture and weak low level instability due to the 850mb cold advection over the warm ocean/bay water. Otherwise, across the interior expect some partial clearing overnight. Lows generally falling into the upper 40s NW to lower 60s close to the coast where the clouds and onshore flow will keep temps warmer.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/. As of 300 PM EDT Friday .

A very quiet weekend expected across the area as strong high pressure dominates the eastern part of the country. Still cannot rule out a sprinkle or light shower on Saturday close to the coast. In fact, the high res models and even the ECMWF suggest this. Will maintain 20 Pop Saturday SE VA and NE NC. Otherwise, will likely see some stratocumulus development both Saturday and Sunday across the interior due to steep low level lapse rates, but overall there should be plenty of sunshine during the day. Very autumn-like this weekend with with highs only in the 60s due to 850mb temps as low as +5C. Lows generally in the 40s west of I-95 and 50s east of I-95. Breezy to windy as well, especially close to the coast. Gusts up to 25 mph inland and 30-35 mph close to the coast.

LONG TERM /MONDAY THROUGH FRIDAY/. As of 300 PM EDT Friday .

Quiet and seasonable weather will continue through next week as broad high pressure remains over the eastern half of the country. In fact, both the GFS and ECMWF show the entire week dry next week. Heights slowly start to build by Tuesday/Wednesday in response to Teddy moving into the Canadian Maritimes and a strong system moving into the Pacific NW. As such, the below normal temps to start the week will increase to near or perhaps slightly above normal by the end of the week. Will generally follow NBM temperatures through the period. Interesting to note that as the dry/cool Canadian high centers itself overhead Mon/Monday night, the NBM low temperature probabilities show a 15-40% chance of temps dropping below 40F Tue morning across the NW Piedmont. In fact, the NBM suggests a 15-20% chance of temps dropping at or below 37 Tue morning at Louisa. Will not forecast as low as 37, but it certainly seems realistic that we could see some upper 30s Tue morning NW of RIC.

AVIATION /20Z FRIDAY THROUGH WEDNESDAY/. As of 200 PM EDT Friday . Generally MVFR at all sites this afternoon along with gusty N-NE winds as high as 20-25kt. As the offshore low departs, high pressure will build into the area later tonight and persist into the weekend. CIGS should gradually rise to VFR as the afternoon goes on. This high will cause drier air to move into the region this weekend which in turn will allow for the BKN CIGS to scatter out especially inland later tonight into Saturday. Continued VFR and gusty N-NE winds on Saturday, especially close to the coast.

OUTLOOK . Strong high pressure builds into the region Sat-Mon. Mostly VFR conditions are expected, although it will remain breezy to windy near the coast.

MARINE. As of 400 PM EDT Friday .

The remnants of of Sally are now well offshore of the local area, meanwhile a strong area of high pressure will continue to build to the north of the area tonight through the weekend. Latest observations show mainly N to NNE winds at around 20 to 25 knots across most of the waters with gusts in the 30 to 35 knot range. Gale Warnings remain in effect for the southern coastal waters and Currituck Sound as these locations will have the greatest potential to see a sustained period of wind gusts of 35 to 40 knots this evening/tonight and again by Sunday. Wind gusts to 35 knots will be possible across the Lower Chesapeake Bay through this evening, especially at the elevated sensors. Small Craft Advisories remain in effect through the entire weekend for all waters (minus the upper Rivers which will see a period of sub- SCA conditions later Saturday afternoon/night).

With respect to the Gale Warning, conditions likely drop below gale criteria later tonight into Saturday, before increasing Sunday/Sunday night as high pressure builds to near 1038mb across New England. Otherwise, expect the wind to become more northerly today as the remnant low tracks offshore. For areas in the Gale Warning, expect the wind to range from 25-30kt with gusts to 35-40kt through this evening, then again Sunday into Sunday night. Outside the Gale Warning, expect high-end SCA conditions to prevail today through the weekend with a NNE wind ranging from 15-25kt with occasional gusts up to 30kt (35 knots at elevated sites). The Gale Watch will continue for the mouth of the Bay Sunday into Sunday night and has also been expanded to include all coastal zones minus areas north of Chincoteague. Local wind probs show an increasing possibility for Gale gusts during the Sunday/Sunday night timeframe for the coastal waters.

Seas currently range from 6 to 8 feet, and will steadily build to 10-14ft through the weekend. Waves in the Bay will generally be 3-4ft, with 4-6ft+ at the mouth of the Bay. The pressure gradient gradually relaxes early next week and the wind will become NW as high pressure settles across the Appalachians. Meanwhile, Hurricane Teddy tracks nwd well off the coast and this will keep seas elevated during the early to middle portion of next week.

HYDROLOGY. As of 1130 AM EDT Friday .

Area rivers continue to rise, in the Nottoway, Meherrin and Blackwater Basins. Lawrenceville is already at flood and Sebrell, Franklin and Stony Creek will go into flood this evening or early Saturday. Rivers will be slow to subside due to all of the water which needs to move down stream. In addition, a flood warning was issued at Providence Forge on the Chickahominy due to the 2-3" of rain in the headwaters.

TIDES/COASTAL FLOODING. As of 430 PM EDT Friday .

Water levels/tidal departures continue to rise across the lower Bay/lower James (now around +1.5 feet vs. astronomical), while values to the N across the upper Bay are still only around +0.5 feet compared to astronomical tides. Along the Ocean, departures have steadily increased to around +1.0 ft to +1.5 ft. Have gone ahead and upgraded Coastal Flood Watches to Warnings for portions of Hampton Roads, coastal Currituck NC, and Northampton County on the Eastern Shore. Low end warning thresholds are likely met for the previously mentioned locations later tonight and tomorrow, with even higher tidal levels expected by Sunday into Monday. A Coastal Flood Watch remains in effect for coastal portions of the Northern Neck and Middle Peninsula where Moderate Flood thresholds may not be met until later in the weekend. A Coastal Flood Advisory is in effect into Sunday for the MD Eastern Shore along the Bay/Atlantic coasts and Accomac VA due to continued rounds of minor tidal flooding at high tide (Bishops Head MD may approach moderate flood by Sunday). The most significant coastal flood threat for all sites will likely be Sunday into Monday with some sites approaching/surpassing major flood stage (Jamestown, Yorktown, and Kiptopeke).

Swells enhanced by Hurricane Teddy (well offshore), periods of ~17 seconds, and very large waves of 10-12 feet+ will make for very dangerous conditions at the Atlantic Beaches (especially Sunday and Monday). In addition, am concerned about the dune/beach erosion potential, especially for more vulnerable locations, later this weekend into next week. Beach Hazards Statements/High Rip Current Risk will be needed through this weekend into next week. A High Surf Advisory has been hoisted for Virginia Beach/Eastern Currituck as seas are already in the 8 foot range. High Surf Advisories will be needed for the remaining areas by Sunday.

AKQ WATCHES/WARNINGS/ADVISORIES. MD . Coastal Flood Advisory until 10 AM EDT Sunday for MDZ021>025. NC . Coastal Flood Advisory until 2 AM EDT Saturday for NCZ102.
