AREA FORECAST DISCUSSION National Weather Service Wakefield VA 741 PM EDT Tue May 11 2021

SYNOPSIS. A weak front drops across the region tonight. High pressure builds north of the region through midweek . as low pressure tracks across the southeast states. High pressure builds over the area Thursday.

NEAR TERM /THROUGH WEDNESDAY/. As of 740 PM EDT Tuesday .

Weak cold front continues to make southward progress this evening. Radar has been rather quiet for our area so far but CAM guidance continues to show the potential for light showers along and ahead of the frontal boundary. Clouds are increasing across the north early this evening.

Increasing clouds trend continues tonight, as weak front drops across the local area. HRRR time-lagged/ARW is showing about the worst case scenario of some isolated to widely sct showers dropping (mainly) across the northern neck and eastern shore through the course of this evening. Cannot rule out a quick sprinkle most anywhere over the area this evening, so will throw in a slight chc PoP for most zones north of the NC/VA border by midnight. Temps look to drop off quickly initially, but stabilize with increasing cloud cover late and overnight. Lows in the low to mid 40s NW . mid 40s to near 50 central VA/MD eastern shore and upper 40s to low 50s Hampton Roads/NE NC and VA eastern shore.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. As of 225 PM EDT Tuesday .

Cool (modifying) Canadian high pressure builds across the region from the Ohio Valley on Wed, as several weak shortwaves track along the slow moving frontal boundary along and south of our southern CWA. Mostly cloudy/overcast to start the day, with some light overrunning rainfall over the US-58 corridor along and south of the VA/NC border. Overrunning light rain overspreads the southern one-third of the area tomorrow morning, as slow clearing ensues across the north. There will be a gradual trend toward clearing for central and southern tier of counties from midday into the afternoon. Cool again w/ NNE winds and highs from the l-m60s N to the u50s- l60s S.

High pressure continues to build into the area Wed night-Thu, and will result in a clearing sky and cool/dry wx. Meanwhile, weak low pressure will move along the stalled front across the Gulf coast region. Early morning lows Thu morning in the l-m40s u40s- around 50F right along the coast. Mainly sunny Thu w/ highs from the m60s to around 70F. Lows Thu night/Friday in the l-m 40s inland, upper 40s to low 50s along the coast.

LONG TERM /FRIDAY THROUGH TUESDAY/. As of 200 PM EDT Tuesday .

Aforementioned low pressure crossing the deep south toward the SE coast will bring some lingering clouds, especially central and south to begin the day on Friday, and ECMWF does paint in some low QPF . but with the remainder of guidance and NBM nearly dry will keep PoP in silent range for now. Sfc high then builds over the region late Fri through this weekend, eventually sliding offshore into early next weekend. This should translate to slowly moderating temperatures throughout the medium range forecast period. Friday's highs start out in the upper 60s to lower 70s and by the time we reach the weekend, highs will be in the mid to upper 70s. Early morning low temperatures start out in the upper 40s to lower 50s over the weekend, and then lower to mid 50s as we turn to early next week.

Looking ahead, strengthening Bermuda high looks to portend a continuation of the warming trend into the middle of next week, with more typical diurnally-driven convection by the middle of next week.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. As of 740 PM EDT Tuesday .

Weak cold front is still progged to drop south this evening and tonight with at least some potential for light showers along and ahead of the front. Clouds are increasing across the northern terminals and these clouds will filter southward with time tonight into Wednesday. Left VCSH at SBY tonight where confidence in seeing some showers is highest. Winds are generally from the south or west ahead of the front but will quickly swing around to the north behind the boundary. Will show northerly winds increasing to ~10 kt with gusts 15-20 kt for a period overnight. Clouds hang on across the south for at least the first half of the daylight hours across the southern terminals with more clearing expected for the northern half of the area.

Outlook: Expecting mostly VFR conditions Wednesday into the late week period. Northerly flow continues through Thursday before high pressure builds near the region.

MARINE. As of 230 PM EDT Tuesday .

Front is well south of the area this afternoon with weak surface high pressure right off the coast. Calm marine conditions currently with a light onshore flow. Waves in the bay around a foot and seas 2- 3 ft.

A weak boundary moves across the area late tonight and strong high pressure builds in from the NW. Winds become northerly and increase to 15-25 kts with gusts around 30 kts over the Bay, rivers, southern coastal waters, and Currituck Sound. SCA's go into effect late tonight for these areas and run through Wednesday morning. Winds in the middle and northern coastal waters are expected to remain below SCA criteria. There may be a narrow window of 2-3 hours early Wednesday morning where wind gusts approach 25 kts, but can more than likely be handled with a Marine Wx Statement rather than a SCA. Waves in the bay and seas will increase to 2-4 ft overnight, with some 5 ft seas possible over the southern coastal waters.

Winds diminish to 5-15 kts by Wednesday afternoon along with waves subsiding to 1-2 ft and seas 2-3 ft as the pressure gradient relaxes. High pressure and sub-SCA conditions expected from Wednesday afternoon through the remainder of the week and the weekend.
