AREA FORECAST DISCUSSION National Weather Service Wakefield VA 623 AM EST Thu Feb 27 2020

SYNOPSIS. A strong cold front will track offshore early this morning. Cooler, drier weather will return to the region today into next weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 355 AM EST Thursday .

Current wv imagery depicts a potent trough lifting newd through the Mid-Atlantic and Northeast. Locally, conditions are drying out, with only some lingering showers from the Nrn Neck to the Ern Shore. Overall, this system produced rainfall generally 0.1" or less from the Piedmont into central VA, and up to 0.2-0.3" over the Ern Shore. Additionally, a couple of thin lines of showers earlier in the overnight produced isolated wind gusts to ~40mph. Otherwise, a cooler and drier airmass is spreading in from the W with the surface cold front now offshore. Temperatures early this morning range from the upper 30s/low 40s W, to the low 50s along the coast and a W wind of 10-15 mph gusting to 20-25 mph.

Breezy and much drier today. Forecast highs are in the upper 40s to low 50s despite 850mb temperatures falling to -7 to -8C as mixing will be maximized. Dewpoints likely fall into the low teens to around 20F by aftn (upper single digits possible along the coast. A W wind will average 15-20 mph, with gusts to 25-30 mph inland, and 30-35 mph over the Ern Shore (gusts up to 40 mph for the MD coast).

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/. As of 355 AM EST Thursday .

Surface high pressure settles into the Deep South tonight as low pressure lingers over the Saint Lawrence Valley. This will maintain some mixing and low temperatures are forecast to fall into the mid 20s to low 30s as CAA continues.

The latest data continues to show some weak moisture/lift crossing the mountains Friday evening/Friday night. Given this, a slight chc of rain and/or snow showers has been maintained (mainly 00-06z Saturday). Seasonally cool Friday with highs in the upper 40s to low 50s with increasing clouds. Partly to mostly cloudy Friday night with lows in the mid 20s to low 30s. Dry Saturday as high pressure builds in from the W. There will still be some energetic NW flow with the trough moving offshore, and this could result in SCT to occasionally BKN CU, especially E. Cool with highs in the low 40s NW to upper 40s SE.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. As of 330 PM EST Wednesday .

Sunday and the first half of Monday will be fairly quiet with high pressure centered over the SE on Sunday and shifting off the SE coast on Monday. A more unsettled pattern sets up late Monday through midweek. A trough will dig through the SW US and by Wednesday ejects northeastward towards the OH valley. Out ahead of the trough, a series of disturbances will increase the chances for rain. Monday night through Wednesday morning the chances for rain will be mainly across western and northern portions of the forecast area, with the greatest chance for areawide rainfall occurring the second half of Wednesday ahead of an approaching cold front.

Temperatures will be seasonable on Sunday with high temps upper 40s to lower 50s. Monday through Wednesday will be well above normal with high temps in the 60s on Monday and Tuesday and may very well reach the 70's for most on Wednesday. Low temps will also be mild only dropping into the 40s on Tuesday morning and 50s on Wednesday morning.

AVIATION /11Z THURSDAY THROUGH MONDAY/. As of 625 AM EST Thursday .

A cold front moved through the region overnight resulting in breezy and clearing conditions through the 12z TAF period. The FROPA has resulted in strong W winds of 10-15 kt with gusts to 25 kt this morning. Winds will increase to 15-20kt with gusts to 30kt later this morning through the afternoon. Winds will begin to wane this evening to around 10 kt. Current VFR conditions are expected to continue through the 12z TAF period.

OUTLOOK . A quick moving trough will bring a very minimal chc of light rain or snow showers Friday evening-Friday night, before high pressure and dry conditions return on Saturday and remain through Monday.

MARINE. As of 430 AM EST Thursday .

A strong cold front is positioned just along the Mid-Atlantic coast early this morning. The cold front will continue to move offshore on Thursday. High pressure is building into the area from the southwest, while a low pressure system is deepening over southeastern Quebec. This is given us a strong west wind behind the cold front. Winds are W 12-20 kt with gust 20-25 kt across our coastal waters. West winds will increase during the day on Thursday with sustain winds 20-25 kt and gusts up to 30 kt (Up to 35 kt across Atlantic waters north of Cape Charles). The exception will be for the Atlantic Ocean coastal waters offshore of MD. Winds will be slightly stronger farther north, with winds W 25-30kt and gusts up to 40 kt. Gale Watch has been upgrade to a Gale Warning for the ocean waters north of the VA/MD state line from Thursday afternoon to early Friday morning, while SCAs remain in effect for coastal waters south of the VA/MD state line, Chesapeake Bay, tidal rivers, and Currituck Sound.

A broad area of low pressure will remain across southeastern Canada and the Northeast U.S. into the weekend. Winds will slightly decrease as the low pressure system weakens Friday. Winds are expected to turn SW and be 15-20 kt with gusts of 25 kt, decreasing to 10-15 kt Friday night. A cold front will cross the coastal waters Saturday and winds will increase and turn NW 15-20 kt with gusts up to 25 kt. High pressure will build over the region Sunday with winds decreasing.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
