AREA FORECAST DISCUSSION National Weather Service Wakefield VA 338 PM EST Sat Dec 14 2019

SYNOPSIS. High pressure rebuilds over the local area tonight through Sunday before the next system impacts the region late Monday and Tuesday.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. As of 245 PM EST Saturday .

Latest weather analysis reveals ~992mb sfc low pressure over the northern Mid-Atlantic. Associated coastal trough/boundary remains in place along the Mid-Atlantic/Southeast coast early this afternoon. Regional radar mosaic showing showers have pushed offshore this aftn, along with another spoke of upper level shortwave energy. Once last wave noted pushing across the Carolinas this afternoon will push offshore tonight, with clearing sky trend to continue through tonight. W winds will increase late this afternoon, with winds gusting to as high as 25 mph at times over Hampton Roads and eastern shore. Temperatures at 19z average from the low 50s NW to around 60/lower 60s across the SE. Low temperatures late tonight/early Sunday will generally range from the mid to upper 30s with lower 40s at the coast.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/. As of 245 PM EST Saturday .

Weak high pressure builds across the southeastern United States on Sunday, with downslope flow aloft allowing for mostly sunny and dry conditions w/high temperatures in the 50s. Surface high pressure traverses the local area Sunday night, then moves well offshore on Monday. Meanwhile, a cold front will approach the region from the west during the day on Monday with chances for rain increasing over N/NW portions of the local area from late afternoon Monday into early Tuesday morning. Monday will generally feature warmer temperatures ahead of the approaching front, although increasing clouds and likely low stratus/fog Monday morning will prohibit max temps from reaching their full potential. Expect highs to range from the upper 40s to low 50s NW to the low to mid 60s across the SE. Non-diurnal temperature curve will likely result in rising/steadying temperatures Monday night from the lower 40s N to the low/mid 50s across the SE.

Front pushes across the region Tuesday through Tuesday evening. Categorical/likely Pops across the piedmont push east to the coastal plain by aftn, gradually tapering off from west to east late Tuesday afternoon and Tuesday evening. Drying out Tuesday night. Pending exact timing, temperatures will be a challenge across the north ahead of the front. For now will keep highs in the mid to upper 50s . with highs well into the 60s central and south on Tuesday.

LONG TERM /TUESDAY THROUGH SATURDAY/. As of 400 PM EST Saturday .

Cold front will be moving offshore Tuesday night with drying conditions and falling temperatures behind the front. Wednesday morning low temperatures will drop to the upper 20s west of I-95 and upper 30s along the coast. An upper level low pressure will track southeast out of Canada and across the Northeast US Wednesday. This will bring a reinforcing shot of colder air into the region. High temperatures Wednesday will range from near 40 across central VA and MD Eastern Shore to mid 40s across Hampton Roads and northeast NC. Low temperatures Thursday morning will be in the low 20s (upper 20s at the VA/NC beaches).

A cold high pressure system will settle across the region Thursday with high temperatures ranging from mid 30s north to mid 40 south. Friday will remain dry as well with slightly warmer temperatures as the sfc high pressure over the area begins to weaken, with high temperatures in the mid to upper 40s and low temperatures in the mid-upper 20s.

AVIATION /21Z SATURDAY THROUGH THURSDAY/. As of 200 PM EST Saturday .

CIGs have improved to MVFR along the coast/IFR inland this afternoon. A gradual return to VFR conditions is expected later this afternoon and evening, with VFR conditions late tonight/overnight and through Sunday. Winds have become W-NW across the region and will become gusty through early evening before relaxing overnight.

OUTLOOK . VFR conditions expected to persist Sunday night into early next week. The next chance of rain and degraded flight conditions comes on Tuesday. Visibilities then improve early on Wednesday through late week.

MARINE. As of 245 PM EST Saturday .

Frontal boundary is right along the coast early this afternoon. Winds are S/SW 15-20 kts with gusts up to 25 kts for the bay and the coastal waters, and 10-15 kts for the rivers. Waves in the bay are 2- 3 ft, and around 4 ft in the mouth of the bay. Seas are 5-8 ft in the coastal waters. As the front pushes offshore this evening, modest pressure rises behind the front will result in winds becoming a bit stronger this evening. Expect 15-25 kts with occasional gusts around 30 kts. Winds will remain gusty into Sunday as a weak surface trough swings through the area during the overnight hours. By late tonight waves in the bay will build to 3-4 ft with 5 ft at the mouth of the bay, and seas will continue 5-8 ft in the coastal waters. SCA for the lower James is in effect until 12Z Sunday. Currituck sound, the bay, and lower coastal waters until 18Z Sunday. Middle and northern coastal waters SCA was extended until 00Z Monday for lingering elevated seas.

Winds will gradually subside on Sunday as high pressure centered over the SE builds into the region. By Sunday evening S/SW winds in the bay will be 5-10 kts and 10-15 kts over the coastal waters. Expect waves in the bay to gradually subside to 1-2 ft and seas 2-4 ft. Next chance for SCA winds/seas will be on Tuesday ahead of a cold front that will cross the area waters late Tuesday into early Wednesday.

TIDES/COASTAL FLOODING. Anomalies rose to 1.4-1.5 right before today's high tide cycle at Bishops Head and Cambridge, so a coastal flood statement was issued this afternoon for the bayside of the lower Maryland eastern shore as locations there will get right around minor flood stage at this afternoons high tide. The next high tide cycle early Sunday will be lower, and anomalies are expected to level off or drop slightly, so additional coastal flooding is not expected overnight.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
