AREA FORECAST DISCUSSION National Weather Service Wakefield VA 354 PM EDT Tue Oct 19 2021

SYNOPSIS. High pressure builds across the area through Thursday. A cold front crosses the region late Friday. Weak high pressure builds back in from the north for the weekend.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. As of 350 PM EDT Tuesday .

A trough is located over Atlantic Canada with a ridge over the Mississippi Valley. At the surface, high pressure is centered across the Southeast conus. Sunny this afternoon with temperatures ranging from the upper 60s to lower 70s with a WSW breeze. Clear this evening with some passing cirrus overnight. Temperatures drop quickly through the 60s into the 50s this evening, with overnight lows mostly in the 40s, with lower to mid 50s near the coast.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/. As of 350 PM EDT Tuesday .

Dry conditions and warming temperatures are expected Wednesday into Thursday as high pressure builds south of the area Wednesday then off the Southeast Coast Thursday as low pressure moves from the central/northern plains to the Great Lakes. A WSW wind will be 10 mph or less Wednesday, then become more breezy ahead of a cold front Thursday. Highs Wednesday primarily range from the mid to upper 70s, with lows Wednesday night 45-50F inland and lower/mid 50s toward the coast, then highs Thursday are forecast to be mainly in the upper 70s to lower 80s.

By Thursday night, this cold front is expected to be pushing along and east of the Appalachians toward the local area, but the front weakens considerably with the flow aloft from the WSW. Mainly dry Thursday night with increasing mid and high clouds. However, there is a slight chance for mainly light showers later Thursday night. Mild for later October with SW flow ahead of the front and lows ranging from the upper 50s to lower 60s, with mid 60s for coastal SE VA/NE NC. The cold front settles across southern VA and NE NC By Friday. Deep moisture is limited, with only 30-40% PoPs across the SE half of the area, and 20% or less farther N/NW. The 19/12z ECMWF is on the wetter-side of the guidance, but has trended with less QPF than the 00z run. Models depict some CAPE across far SE VA/NE NC, but have opted not to include thunder at this time given rather weak lapse rates. Mostly cloudy with forecast highs ranging from the lower 70s NW to the upper 70s SE.

LONG TERM /FRIDAY THROUGH TUESDAY/. As of 350 PM EDT Tuesday .

The cold front mentioned in the short term period will push south of the area as an upper trough is forecast to swing through the region later Friday into Saturday morning. In general, the 19/12z guidance has trended faster with the frontal passage with drier conditions later Friday night into Saturday morning. Chance PoPs (30-40%) are forecast toward the coast Friday evening, tapering to 20% over the Piedmont then tapering down later Friday night into Saturday morning. Sharpening of the trough aloft through the NE /mid-Atlantic states Sunday- Monday expected to lead to cooler/dry wx (esp late Saturday- Sunday). Models hinting at a possible quick moving system potentially leading to increased clouds and pcpn chances Monday (The 19/12z ECMWF is most aggressive with this). Again, leaded towards the blended guidance with that second system early next week.

Highs will be mainly in the mid 60s to lower 70s Saturday, and mainly in the 60s Sunday-Monday, then 60s to near 70F Tuesday. Lows mainly in the 50s Friday night, then 40s and 50s Saturday night-Monday night.

AVIATION /20Z TUESDAY THROUGH SUNDAY/. As of 145 PM EDT Tuesday .

High pressure is centered over the southern Appalachians as of 18z. This area of high pressure will slide eastward across the Southeast during the next 24 hours. This will result in dry and VFR conditions across the area through tonight and Wednesday. Sunny this afternoon with a WNW wind of 5-10kt, which will occasionally gust to 15-20kt through 21z, mainly at SBY. Clear tonight aside from some passing high clouds after 06z, with a light WSW wind. Sunny Wednesday with a W or WSW wind of 5-10kt.

High pressure will continue to prevail Thursday with dry and VFR conditions continuing. A SW wind will increase to 10-15kt with gusts to ~20kt ahead of an approaching cold front Thursday afternoon. This cold front will bring a chance of showers Friday into Friday night. Mainly dry Saturday and Sunday behind the cold front, with only a slight chance of showers toward the coast Saturday morning.

MARINE. As of 320 PM EDT Tuesday .

Current wx analysis depicts a broad area of high pressure centered over the Southeast and an area of low pressure off the Canadian Maritimes. High pressure has edged enough north that the pressure gradient between the low to the NE and high to the SW has weakened/lifted north of the local waters this afternoon. Winds have begun to shift from NW to W 5-15 kt this afternoon and will gradually become WSW through this evening and into early tonight. Winds may briefly increase to 15-17 kt over the Ches Bay and coastal waters this evening into early tonight, but expect winds to become W and diminish to 10-15 kt by late tonight. Waves and seas are 1-2 ft and 2-4 ft respectively (2-3 ft seas across the northern coastal waters and 3-4 ft seas across the southern coastal waters). Expect seas to subside to 2-3 ft this evening. Waves and seas will remain 1- 2 ft and 2-3 ft respectively through early Thurs afternoon.

High pressure will continue to build NE into the area, while remaining centered over the Southeast, Wed before moving off the Southeast coast Thurs. Meanwhile, an area of low pressure will track from the Great Lakes into SE Canada/far northern portions of the Northeast Thurs into Thurs night with a trailing cold front dropping SE over the local waters Fri/Fri night. S/SW winds ramp up Thurs afternoon through Thurs night ahead of the approaching cold front with a period of SCA conditions possible. However, uncertainty remains regarding how early the SCA-level winds will begin (Thurs afternoon or Thurs evening) and given that the event is >48 hrs away, will hold off on headlines for this update cycle. There will also be the potential for SCA conditions for the northern coastal waters Thurs night due to 5 ft seas.
