AREA FORECAST DISCUSSION National Weather Service Wakefield VA 944 PM EDT Thu Apr 25 2024

SYNOPSIS
Strong high pressure will anchor itself over the Northeast through Friday, before shifting offshore this weekend. A significant warm up begins Sunday and last through the middle of next week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
As of 810 PM EDT Thursday...

Forecast is in good shape with minor adjustments to temps and dew points to match observations. Increased overnight lows a degree or two based on more cloud cover. Lows range from the mid 40s SW to the upper 30s for the MD Eastern Shore where cloud cover will be thinnest.

Previous Discussion: Strong 1031mb high pressure is centered over Lake Ontario this afternoon. Meanwhile, what remains of the cold front that passed through the area yesterday and last night is now well off the Southeast coast. What we are left with is decent onshore winds across the mid-Atlantic this afternoon, which has caused considerable cloud cover from roughly the I-64 corridor on north and east to the coast. In addition, temps are much lower today than they were yesterday, generally in the 50s near the coast to nr 70 over south-central VA. For the most part, am expecting this onshore flow to persist tonight although it will be weakening. Clouds will be stubborn to break up overnight and am expecting low clouds to persist into Friday morning. The only exception may be the lower MD Eastern Shore where clouds should begin to break prior to sunrise. It will be a chilly night with lows in the low/mid 40s inland, with mid to upper 40s at the coast. Inland portions of the lower Maryland Eastern Shore should see clearing overnight and with decoupling winds, could see lows in the mid to upper 30s Friday morning. This could result in patchy frost in typically cooler, more sheltered areas, but don't think it will be widespread enough for a Frost Advisory.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
As of 325 PM EDT Thursday...

High pressure will settle over New England on Friday, keeping a weaker onshore flow regime in place. This portends another cool day Friday, with highs similar to those of today (50s at the coast, low to mid 60s inland). Look for a mostly sunny sky near the coast and a partly to mostly cloudy sky across the Piedmont. It will be a little bit milder Friday night as the airmass modifies, with lows staying in the mid 40s inland.

LONG TERM /SATURDAY THROUGH THURSDAY/
As of 325 PM EDT Thursday...

A high amplitude upper ridge axis will be in place over the eastern seaboard to begin the day on Saturday, with surface high pressure settling in just off the New England/northeast coast.
Meanwhile, a low pressure center will weaken as it drifts north across the upper midwest, sending a warm front across the Ohio River Valley and into the northern Mid-Atlantic Saturday morning. It may extend just far enough south to give us a slight chance of a rain shower, particularly across the northwest section of the CWA Elsewhere, expect a partly to mostly cloudy sky and slightly higher temperatures. Highs in the upper 60s to around 70 degrees inland, and in the low to mid 60s along the coast.

As high pressure builds offshore and settles in the western Atlantic late in the weekend through early next week, expect temperatures to quickly trend back up above normal through the period; highs jump into the 70s along the coast to low 80s inland on Sunday, with highs in the mid to upr 80s for most locations away from the immediate coast on Monday through Wednesday, before the upper ridge finally starts breaking down by the middle of next week. The next front approaches from the west Mon/Tue next week. Our next chance for showers and isolated storms will be possible with the frontal passage itself by Tuesday and Wednesday.

AVIATION /02Z FRIDAY THROUGH TUESDAY/
As of 810 PM EDT Thursday...

Onshore flow continues to bring low stratus to the SE terminals (ORF/PHI/ECG). Mix of MVFR and IFR at these sites to start the evening. Flight categories are likely bounce around for a few hours before settling into IFR at ECG and ORF. Will show prevailing MVFR CIGs at PHF. MVFR CIGs eventually spread toward RIC by late evening. Expect CIGs to improve toward sunrise with VFR prevailing at all sites by late morning. NE winds generally 5-10 kt tonight with some gusts 15-20 kt after mid morning Friday.

Outlook: Dry/VFR conditions are expected at all terminals through the weekend.

MARINE
As of 940 PM EDT Thursday...

Key Messages:

- SCAs remain in effect for the lower bay, lower James, Currituck Sound, and all coastal water zones (extended the headline through 1 am Fri for the lower James).

- A prolonged period of elevated seas/waves due to onshore flow is expected into Friday night.

Large high pressure situated over the NE CONUS is building in over the local area this afternoon as last night's cold front pushes south and away from the area. There is enough of a pressure gradient between these features to allow for gusty onshore winds today.
Latest obs show NE winds of 10-15kt in the upper bay and upper rivers with 15-20kt elsewhere. Buoy obs show seas of 5-7 ft across the coastal waters. Winds will gradually diminish to 10-15kt in the bay/rivers and ~15kt over the coastal waters through the evening and overnight as the pressure gradient slackens. These conditions are expected to continue through the day Friday, then diminishing further Friday night. Continuous onshore flow means that seas will be slow to comes down under 5ft. Therefore, SCAs for the coastal waters (and mouth of the bay) likely continue into late Friday evening.

Regarding the rest of the forecast period, high pressure will build into the area this weekend before being suppressed to the south later in the week. Onshore flow persists through Sat as the high will be centered to the N. As the high pushes offshore and then south, the winds become southerly Sun, then SW Mon-Wed, at 10-15kt.

TIDES/COASTAL FLOODING
As of 845 PM EDT Thursday...

-Added a Coastal Flood statement for the middle peninsula and northern Neck to cover the upcoming high tide cycle. Water levels may potentially reach minor flood thresholds (or at least should be withing a few tenths) at Lewisetta, Windmill Pt, West Point, and Tappahannock.

A prolonged period of NE flow is expected to last into the weekend. Mainly nuisance flooding is possible across the lower bay, James River, VA Atlantic- facing beaches, eastern Currituck County, and Dorchester County with tonight's high tide. As such, Coastal Flood Statements are in effect for these locations. Locally minor flooding is possible along the S/W portion of the James River during this evening's high tide due to a favorable fetch of swell given NE winds. Smithfield will likely reach minor flood stage (potentially high-end minor) with Sewell's Point also showing the potential for reaching minor flood stage. As such, a Coastal Flood Advisory has been issued for these areas.
