AREA FORECAST DISCUSSION National Weather Service Wakefield VA 304 PM EST Tue Feb 20 2024

SYNOPSIS
High pressure will promote dry and seasonable conditions through Wednesday night. A trough of low pressure moves across the Mid-Atlantic region late Thursday into Friday bringing a chance of showers. Seasonably cool and dry this coming weekend, before a warming trend commences early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
As of 245 PM EST Tuesday...

1034mb high pressure is centered from southern QB into New England this afternoon, and extends to the SW into the Mid- Atlantic. Meanwhile, weak low pressure lingers well off the Southeast coast. Sunny for most of the region this afternoon, with only a few high clouds across NE NC. Temperatures range from the mid/upper 40s along the coast with onshore flow, to the lower 50s inland. Clear and chilly once again with high pressure and a dry airmass in place. Forecast lows range from the mid to upper 20s away from the coast, to the lower to mid 30s along the coastlines of SE VA and NE NC where light onshore flow will persist.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
As of 245 PM EST Tuesday...

High pressure shifts toward Atlantic Canada Tuesday Wednesday, with a surface ridge axis lagging to the SW into the Mid- Atlantic. Sunny Wednesday as high pressure continues to prevail, with only a few clouds possible along the coast with onshore flow. Temperatures remain near to slightly below seasonal averages, and range from the mid/upper 40s along the coast with onshore flow, to the lower to locally mid 50s inland.

High pressure settles in vicinity of the coast Wednesday night and then moves offshore Thursday as a transitory upper ridge builds across the East Coast, with a trough moving into the Ohio Valley by Thursday afternoon. Partly cloudy to mostly clear Wednesday night and not as chilly with lows in the upper 20s to mid 30s. Increasing clouds and milder Thursday with highs in the lower 50s over the Eastern Shore (upper 40s immediate Atlantic coast), and in the mid 50s to near 60F elsewhere.

The upper trough and a cold front track across the area Thursday night into Friday, bringing a chc of showers later Thursday night into Friday morning. QPF is minimal, and generally 0.1-0.25". The airmass behind the front is Pacific in origin. Therefore, it could even be milder behind the front Friday with highs in the upper 50s to mid 60s. Cloudy in the morning, and then becoming partly sunny in the afternoon.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
As of 245 PM EST Tuesday...

A northern stream trough and secondary cold front drop across the region Saturday, with high pressure building across the area Sunday. A few sprinkles or light showers are possible Saturday, but PoPs remain < 15% at this time as moisture is limited.
Otherwise, variably cloudy Saturday with temperatures returning to near seasonal averages. Dry and mostly sunny Sunday with temperatures remaining near seasonal averages. By early to middle of next week, there is model consensus for the trough to quickly dampen and move offshore as an anomalous upper ridge builds in from the W. As a result, a potentially substantial warming trend commences early next week. Mainly dry early in the week, with a chc of showers by midweek as a cold front approaches from the W.

AVIATION /20Z TUESDAY THROUGH SUNDAY/
As of 1250 PM EST Tuesday...

1034mb high pressure is centered over New England as of 18z, and extends to the SW into the Mid-Atlantic. Meanwhile, low pressure lingers off the Southeast coast. VFR conditions prevail. Sunny for most sites, with only some cirrus at ECG.
The wind is E to NE 8-12kt, and locally 10-15kt at ORF and ECG.
VFR conditions continue to prevail tonight into Wednesday as high pressure dominates. The only exception would be if some bands of marine SC develop Wednesday, and this would mainly be at ORF and ECG. The wind will light out of the NE tonight, and locally 8-12kt at ORF/ECG, and then will mainly be NE 5-10kt Wednesday, and locally 10-15kt at ORF/ECG.

Dry and VFR conditions continue Wednesday night and Thursday. A chance of rain along with degraded flight conditions returns Thursday night into Friday as an upper level trough tracks across the region. VFR and dry conditions return late Friday through Sunday.

MARINE
As of 300 PM EST Tuesday...

Key Messages:

- Northeast winds remain elevated into Wednesday. Small craft advisories remain in effect for the southern waters through tonight.

- Seas build to 5-9 ft starting Wednesday and remain elevated into the weekend. Small craft advisories have been issued/extended for all of the coastal waters through Friday night.

Onshore NE flow continues over the waters this afternoon with low pressure well offshore of the Carolinas and high pressure over coastal New England. Winds were 15-25 kt from Cape Charles south to Duck NC and ~15 kt in the lower bay and mouth of the bay. Seas are 4- 6 ft S and 3-5 ft N (these values are higher than most numerical wave guidance). Small craft advisories are in effect for the coastal waters S of Parramore Island and for the lower and mouth of the bay through at least tonight. Elsewhere, winds were sub-SCA and generally 10-15 kt.

NE winds continue into Wednesday, but gradually subside into Wednesday night and turn to the N. High pressure moves over the area and shifts offshore later Thursday morning. This will turn the flow southerly for Thursday. S-SSE winds could become quite gusty Thu night with 15-20 kt possible in the bay and coastal waters. At the same time, NWPS and NBM wave heights and swell data continue to show increasing easterly swell Wed night and lasting into later Friday/early Saturday (dominant period increases to 11-12 sec). This will increase wave heights on the coastal waters to 6-9 ft with waves at the mouth of the bay nearing 4-6 ft (highest Thu morning).
Thus, have extended the SCA for the srn coastal waters through Fri aftn (for now) and have raised new SCAs further N, which go through early Sat.

Low pressure tracks across the waters Friday, with a cold front dropping through Friday night into Saturday. This will bring a surge of colder air and models are in somewhat better agreement regarding the timing of the strongest winds. The current forecast has NW winds increasing to 15-25 kt for most of Saturday with gusts 25-30 kt possible (highest northern half of the waters though SCAs are certainly possible everywhere).
