AREA FORECAST DISCUSSION National Weather Service Wakefield VA 658 AM EST Sun Jan 26 2020

SYNOPSIS. High pressure builds in today. A weak disturbance tracks across the area on Monday before high pressure builds in again for midweek.

NEAR TERM /THROUGH TONIGHT/. As of 300 AM EST Sunday .

Latest analysis this morning shows a low pressure system over NE and high pressure over the deep south. Locally, a weak surface trough continues to slowly push through the area. This is resulting in stubborn cloud cover that is slow to erode over the VA peninsula over to the eastern shore. Elsewhere, mostly clear skies and near calm winds have allowed temps to drop quickly. Already in the lower 30s west of Richmond, with mid and upper 30s across south central VA and inland NE NC. The cloud cover is holding temps over the peninsula and eastern shore in the lower 40s. Temps out west will hold nearly steady the rest of the morning, while temps over the peninsula and close to the coast will continue to slowly fall as the cloudy cover eventually erodes. Overall low temps this morning will be near 30 west to upper 30s east.

High pressure will move from the deep south over to the SE coast during the day today, with zonal flow aloft. Mostly sunny skies expected for much of the area today, with a bit more cloud cover across the northern third of the area during the afternoon as another weak surface trough passes through. High temps this afternoon in the low to mid 50s.

SHORT TERM /MONDAY THROUGH TUESDAY/. As of 300 AM EST Sunday .

A weak shortwave over the TN valley will cross the area on Monday. A weak disturbance ahead of the shortwave will increase cloud cover and bring a slight chance of rain to mainly southern VA and NE NC. Latest QPF forecasts are still in good agreement that rainfall amounts will be light, on the order of just a few hundredths of an inch. Low temps Monday in the 30s and high temps low to mid 50s.

Rain chances end late Monday as the disturbance exits the area to the east. Drier and slightly cooler weather on Tuesday as high pressure builds in from the Midwest. Low temps upper 20s west to mid 30s SE, and high temps ranging from the mid 40s to around 50.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 320 PM EST Saturday .

A weak shortwave will move through the southern portion of the CWA late Monday night into early Tuesday bringing with it a slight chance of a few scattered rain showers Monday afternoon. High pressure moves in Tuesday and persists through Wednesday evening. Another shortwave moves through on Thursday possibly spinning up a weak coastal low off the SE coast well offshore. Models have come into more agreement that any low pressure forming will be too far offshore to provide any widespread precipitation for the CWA. Have therefore lowered PoPs to <25%. High pressure once again moves into the region Friday and will persist until early Saturday. Next weekend becomes a little more interesting with both the GFS and EURO developing a coastal low off of the Carolina coastline and bringing it up the NE coast Saturday into Sunday. However, we will be lacking any substantially cold air and therefore rain is the most likely precipitation type.

Temperatures will be near seasonal through the period. Lows Tuesday-Thursday nights will range from the mid-upper 20s in the NW to the low-mid 30s in the SE. Lows on Friday and Saturday nights will be slightly warmer with low 30s in the NW and upper 30s to around 40F in the SE. Highs will be in the 40s on Wednesday and will range from the mid-40s in the NW to lower 50s in the SE on Thursday-Saturday.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. As of 625 AM EST Sunday .

Clouds over the VA peninsula and the eastern shore have been slow to erode this morning even as drier air continues to push into the area. Forecast soundings at SBY suggest that SCT to BKN clouds may hang on through the afternoon as another weak surface trough moves through the area. Ceilings earlier in the evening dropped briefly to MVFR at PHF and SBY, however they have been VFR (around 5k ft) for the past several hours. Kept all locations VFR through the TAF period, however ceilings at PHF and SBY could briefly drop to MVFR (around 3k ft) at times this morning. Winds today will be W/SW 5-10 kts, and they are expected to be 5 kts or less overnight into early Monday morning.

A weak shortwave will move through during the day on Monday bringing a slight chance of showers and sub-VFR ceilings mainly for ORF/ECG.

MARINE. As of 650 AM EST Sunday .

Seas have been ~4 ft at buoy 44100 and 44099 for the past few hrs so have dropped SCAs for the coastal waters S of cape Charles light w/ this update (only remaining SCAs are for the coastal waters N of Cape Charles where seas are 4-5 ft).

Low pressure is currently centered well N of the local area across Ontario and the St Lawrence Valley with sfc high pressure over the Gulf coast ridging NE into the Carolinas. W winds 5-10 kt prevail early this morning with waves in the Bay 1-2 ft and seas 3-5 ft on the coastal waters in 10-11 sec period E swell. SCA headlines will remain in effect for the northern zones through 1 pm as seas slowly subside.

Low pressure to our N gradually shifts to the E and moves off to Atlantic Canada Mon/Mon night, forcing a dry cold front through the region Monday night/early Tuesday. Guidance remains in decent agreement showing decent CAA behind the boundary and current forecast is for marginal SCA conditions for the Bay (to 15-20 kts) through late Tuesday morning before the gradient slackens heading into the mid week period. SCAs may be needed for the Bay and it could be close on the coastal waters as well (primarily for seas building back to 4-5 ft).

CLIMATE. Due to a tipping bucket error at SBY ASOS yesterday, precipitation for Sat 1/25 was substituted with data from the RAWS site at Powellville (1.03").

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.
