AREA FORECAST DISCUSSION National Weather Service Wakefield VA 403 PM EST Fri Jan 22 2021

SYNOPSIS. Another dry frontal passage tonight will usher in cold Canadian high pressure from the northwest over the upcoming weekend. Low pressure tracks across the area early next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 355 PM EST Friday .

Afternoon surface analysis shows low pressure moving SE out of SE Quebec and into the Northeast. Meanwhile, high pressure is centered over the Mid West. Temperatures are mainly in the low to mid 50s (mid to upper 50s in NE NC). Cirrus clouds are beginning to thin out over the region and will continue to do so into the evening with a mostly clear night expected apart from perhaps a few lingering cirrus over the Eastern Shore.

Winds are W around 15 mph with gusts up to 20-25 mph. Breezy conditions will begin to subside through the rest of the afternoon except for locations near the coast which may continue to see wind gusts until around sunset. A dry cold front is still expected to cross the region tonight as cold high pressure slowly builds toward the region. CAA will help keep winds around 5 MPH overnight which will help keep radiational cooling from being optimal. Therefore, have lows generally in the low to mid 20s over most of the region with upper 20s to near 30F near the coast and along the Eastern Shore where winds will be a little stronger.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY NIGHT/. As of 400 PM EST Friday .

The high continues to build ESE on Saturday before becoming centered over the area Saturday night. The high will then move offshore during the day on Sunday. Sunny but breezy along the immediate coast and along the Eastern Shore on Saturday. With continued CAA from the NW, highs will only top out in the upper 30s-mid 40s (lowest NE/highest SW). With the high overhead Saturday night, winds will fully decouple (except for perhaps along the immediate Atlantic coast) Saturday night. With clear skies and dry air in place, temps will quickly fall after sunset, bottoming out in the upper teens to low 20s for most of the area with a few mid 20s SE.

Weak southerly return flow sets up by late Sunday. In addition, our next system starts to organize over the Plains. High temps will remain seasonably cool in the low to mid 40s (upper 30s to low 40s along the Eastern Shore). Mid/high clouds will increase across the area through the day with continued dry wx. With cloud cover over the region Sunday night, lows only drop to the low to mid 30s for most locations (upper 20s to low 30s over the Eastern Shore).

PoPs begin to increase from SW to NE late Sunday night into Monday with the highest PoPs (80-90% across the FA) Monday afternoon into the early evening. Temps are expected to remain above freezing during the duration of the precip and therefore a cold rain is expected as opposed to any winter weather. The only exception could be the far NW piedmont (Louisa/Fluvanna) where temps could hover around freezing at the onset Sunday night/early Monday morning before warming into the mid 30s by late Monday morning. In this small area, a brief coating of freezing rain cannot be ruled out. Temps warm into the upper 30s NW to the upper 40s SE for VA/MD and into the upper 40s to low 50s in NE NC by Monday afternoon. The low moves NE of the area Monday night with PoPs tapering off quickly by Tuesday morning. Total QPF of around 0.75" SW to 0.25-0.30" NE expected. Lows Monday night ranging from the low 30s NW (33-34F) to the mid 40s SE.

LONG TERM /TUESDAY THROUGH FRIDAY/. As of 300 PM EST Friday .

One area of sfc low pressure, that will bring widespread rain on Monday, will be tracking out to sea early Tuesday morning with a slight chance for a few showers near the coast. Another sfc low pressure will track north of the area Tuesday with a warm front extending southeast of the center and a cold front southwest. The warm front will likely lift north across our area Tuesday morning as the sfc low tracks to our north. High temperatures will range from north to south across the area as the warm front stalls across central/northern VA and the Eastern Shore. High temperatures may be in the low 60s along and south of the VA/NC border, mid to upper 50s along the I-64 corridor, and upper 40s to low 50s north of I-64 and the Eastern Shore. Cold front move across the area with high pressure building in from the north on Tuesday night. This strong area of high pressure will over our area through the end of the week, keeping the cold air locked in place. Low temperatures Wednesday and Thursday morning will be 25-30F for most of our area, and 30-35F for Hampton Roads. Dry weather expected for Wednesday with high temperatures in the 40s.

All eyes will turn to the possibly of a winter storm on Thursday. As previously mentioned, cold air will be in place Wednesday night/Thursday with a strong sfc high pressure (~1040 mb) is centered near the Hudson Bay and extending south into Mid-Atlantic and Carolinas. A deep trough will be positioned along the West Coast next week. A short wave will move onshore across southern California Tuesday and track across the U.S. Wednesday. As the shortwave approaches the East Coast, it will likely dive southeast across our area Thursday as a ridge build to our west, west of the Appalachian Mountains. At the same time, a sfc low will develop across the Gulf Coast states and track east towards the Atlantic Ocean. The sfc low pressure is expected to strengthen as it interacts with the deepening shortwave and warmer waters of the Gulf Stream off the Carolina coast. There is uncertainty in how close will the sfc low pressure will be to our area. The GFS has the sfc low the closest to the area, near Cape Hatteras. This solutions bring impactful amounts of snow to the I-95 corridor and MD Eastern Shore and mostly rain to Hampton Roads, with a mix in between across eastern VA and NC. While the ECMWF has the low pressure well off the coast, as only light snow across the area as the shortwave moves over the area.

After the storm moves off the East Coast, dry conditions will return with cold air remaining in place due to the strong high pressure mentioned earlier.

AVIATION /21Z FRIDAY THROUGH WEDNESDAY/. As of 1250 PM EST Friday .

VFR conditions prevail through the 18z TAF period. SCT cirrus have developed over the region but are expected to slowly dissipate from SW to NE later this afternoon into this evening. SKC conditions expected to prevail tonight apart from a few cirrus over SBY. W winds 10-15 kt with gusts 20-25 kt will continue into the late afternoon over all terminals before subsiding to around 10 kt around/shortly after sunset. Winds become NW then NNW tonight and decrease to ~5-8 kt. Gusty NW winds 10-15 kt sustained with gusts to 25 kt will be possible along the coast late Saturday morning into the afternoon. Gusty winds Saturday are most likely at SBY.

Outlook: High pressure will continue to build into and over the region Saturday night into Sunday. Low pressure will bring rain to the region early next week, with sub-VFR conditions likely for a decent portion of the Monday-Monday night timeframe.

MARINE. As of 345 PM EST Friday .

Afternoon analysis shows low pressure pulling well away from the Northeast as high pressure builds into the local area from the west. Winds have been tricky today with westerly flow at the surface and aloft leading to breezy conditions and warm temperatures for land areas with some spill-over into the rivers and southern Ches Bay this morning and today. Winds are averaging westerly at 5-15 kt with gusts 15-20 kt. Waves are 1-2 ft with seas 1-3 ft.

A cold front across the Ohio Valley is poised to move through the region this evening as high pressure builds into the region. Cold advection and pressure rises on the order of 5mb/6hr will lead to increasing NW winds tonight. Winds build to 15-25 kt with gusts to 30 kt over most of the local waters with 20-30 kt and gusts to 35 for the northern coastal waters. SCA headlines are in effect for all waters from tonight into Saturday. Opted to include the upper James, York, and Rappahannock Rivers in SCA headlines starting at 4am and lasting into the afternoon hours. Upgraded the Gale Watch to a Gale Warning for the northern-most coastal zone from early Saturday morning through the afternoon. Cold advection and the pressure gradient will slacken into Saturday night but SCA headlines will likely need some temporal extensions into the daylight hours of Sunday for the Bay and coastal waters in subsequent forecasts.

Low pressure moves over the region Monday night into Tuesday with the potential for additional marine headlines. Another area of low pressure could affect the region late in the week with the potential for more substantial marine impacts.
