AREA FORECAST DISCUSSION National Weather Service Wakefield VA 822 PM EDT Mon Apr 29 2024

SYNOPSIS
High pressure will shift farther off the southeast coast and out to sea on Tuesday, as a weak cold front approaches from the northwest. The front will cross the area late Tuesday night through Wednesday with scattered showers and storms possible Wednesday into Wednesday evening. Dry conditions are expected Thursday and Friday, with rain chances returning this weekend, as another cold front moves into the area.

NEAR TERM /UNTIL 8 AM TUESDAY MORNING/
As of 815 PM EDT Monday...

The latest WX analysis indicates a strong upper level ridge in place from the SE US to the eastern Great Lakes, with >1020mb sfc high pressure centered off the SE US coast. The sky is mainly clear other than a few high clouds, and temperatures remain warm, with readings as of 8 PM mostly ranging through the 70s (locally a few places ares still in the lower 80s N of RIC with 60s along the Atlantic coast of the eastern shore). Highs today were mostly in the mid to upper 80s, falling short of any record highs (see climate section). For the overnight period, it will remain dry and mostly clear with a light SW low level flow. Lows will mostly be from 60-65F, with upper 50s possible along the Atlantic coast of the eastern shore.

SHORT TERM /8 AM TUESDAY MORNING THROUGH THURSDAY/
As of 400 PM EDT Monday...

The sfc high will shift farther off the SE coast and out to sea Tuesday through Wed. Still very warm on Tue, with a mostly sunny sky becoming partly sunny, as a weak cold front starts to approach from the WNW. Highs will mainly be in the lower to mid 80s. That front will then gradually push into and across the region Tue evening through Wed evening. There may be isolated showers or a tstm Tue evening into Wed morning. But then, the best chance for showers/tstms (30-54%) will be from late Wed morning into Wed evening, as the boundary slowly sinks SE through the area. Lows Tue night in the lower to mid 60s, with highs on Wed in the mid 70s to lower 80s. The highest PoPs will be across srn/SE counties where around ~0.25" of rain will be possible. The rain will end Wed night with dry weather expected for late Wed night through Thu, as the front pushes SSE of the area and upper ridge of high pressure builds into/over the region. Lows will range through the 50s Wed night, with highs on Thu ranging from the upper 60s to mid 70s near the Bay/coast, to the upper 70s to lower 80s inland/Piedmont.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
As of 415 PM EDT Monday...

High pressure ridge aloft will maintain dry weather Thu night through Fri. At the sfc, high pressure will be centered over New England or just offshore, resulting in onshore flow everywhere.
This will keep temps cooler along the coast and warmer inland.
Highs on Fri in the lower to mid 80s inland/Piedmont, and in the mid 70s near the Bay/coast (coolest along the Atlc beaches of the Eastern Shore). There may be an isolated shower or tstm Fri evening/night over WNW counties, as a cold front starts to approach from the WNW.

A cold front will gradually push into and across the region Sat into Mon, providing decent chances for showers/tstms. Due to plenty of cloud cover expected, highs will range through the 70s into the lower 80s.

AVIATION /00Z TUESDAY THROUGH SATURDAY/
As of 800 PM EDT Monday...

VFR conditions will prevail at the TAF sites through the 00Z/30 TAF period. SSW winds will avg 5-10 kt overnight, with SW winds 10-15 kt, gusting to 20-25 kt for most of the day Tue.
Increasing high clouds Tue, but remaining VFR.

Outlook: Mainly VFR conditions are expected at all terminals into Tue night, with a slight chance of a shower/tstm at RIC Tue evening. Higher chances (30-50%) of showers or tstms will be possible Wed into Wed evening, with brief flight restrictions likely in any tstms. Dry Thu-Fri. A chance for showers/tstms late Fri night through Sat with the next front.

MARINE
As of 300 PM EDT Monday...

Generally benign, sub-SCA conditions, are expected through the forecast period though some gusts to around 20 kt are possible at times.

High pressure remains centered off of the Carolinas with an area of low pressure west of the Great Lakes. This is placing the region under a persistent southwest flow around 10 to 15 knots. Seas persist around 2 to 3 feet (up to 4 feet offshore), and waves in the bay are running around 1 foot (up to 2 feet at the mouth). Southwesterly flow continues overnight and decreases with the loss of mixing. For Tue southwest winds should increase a little after daybreak with mixing resulting to 10 to 15 kt with a few higher gusts possible over the Bay and near shore waters closer to land.

A cold front approaches the waters from the north and northwest late Tuesday night pushing south past Ocean City and the Potomac River in the morning reaching the lower Bay and NC waters later in the afternoon. S to SW winds will increase slightly ahead of the front (~15 knots over the bay and ~15 to 20 knots over the coastal waters) Tuesday afternoon into Tuesday evening. Seas increase some due to the stronger S winds, with seas approaching 4 to 5 feet out 20 nm, especially north of Cape Charles Light. Winds shift to the N and NE behind the front Wednesday morning and remain around 10 to 15 kt. Generally onshore flow from the NE then E is expected from late Wednesday into Friday. Have increased the NE winds a little with this forecast updated based on the models, but winds remain below SCA criteria around 15 kt with some gusts to near 20 kt possible at times. Another front potentially approaches the waters later this weekend.

CLIMATE
As of 800 PM EDT Monday...

No record highs were set today 4/29. SBY has a chance on Tuesday, while records at the other sites are very unlikely.

Record highs for Tuesday April 30th:

* RIC: 93/1974 * ORF: 93/1988 * SBY: 86/2017 * ECG: 90/1974
