AREA FORECAST DISCUSSION National Weather Service Wakefield VA 246 PM EST Sun Dec 15 2019
SYNOPSIS. A slow moving front will become nearly stationary across the area overnight into Monday. A low pressure system crossing the mid Atlantic region Tuesday will drag a cold front across the area late Tuesday into early Wednesday.
NEAR TERM /THROUGH TONIGHT/. As of 230 PM EST Sunday..
This afternoon high pressure is off the SE coast. Meanwhile, a cold front is slowly drifting towards our area from the NW and is expected to become nearly stationary across our area overnight. The rest of the day will remain dry however clouds will be on the increase tonight. Temps in the mid to upper 50s this afternoon will drop to the low to mid 30s north overnight, with mid 30s to near 40 south. Some patchy fog is expected early Monday morning, especially over southside and inland portions of NE NC.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. As of 230 PM EST Sunday .
A tricky forecast for Monday as the position of the nearly stationary front will have implications for both precip and temperatures. Precip moves in north of the front Monday morning. While most of this precip will be rain, there is a chance for some mixed precip across far northern portions of the VA piedmont and also over the MD eastern shore. QPF amounts will be light and surface temps of 33-35 degrees in these areas will likely result in little to no accumulation. High temps will be highly variable, with low to mid 40s north of wherever the front positions itself, and upper 50s to lower 60s south of the front.
Monday night the front will make a slow progression to the north as a warm front. A low pressure system will track from the TN valley to the Mid-Atlantic early Tuesday. Temperatures will remain steady or climb slightly Monday night into early Tuesday. Low temps Tuesday morning range from the lower 40s north to mid 50s south. Rain chances increase Tuesday morning ahead of a cold front that will cross the western portions of the CWA Tuesday afternoon and exit eastern portions of the area by late Tuesday into early Wednesday. Rainfall amounts on Tuesday generally in the 0.3 to 0.75 inch range. High temps will be mild as the region sits in the warm sector for much of the day. Expect upper 50s north to mid and upper 60s south.
Conditions improve quickly after the frontal passage as high pressure builds into the region overnight Tuesday into Wednesday morning. Modest CAA and clearing skies should drop temps to the lower 20s NW to around 30 SE by Wednesday morning.
LONG TERM /WEDNESDAY THROUGH SATURDAY/. As of 230 PM EST Sunday .
High pressure remains in control Wednesday through Friday. This will result in dry weather and slightly below normal temps during this period. Low temps Thursday and Friday in the 20s, near 30 at the coast, and high temps in the 40s. Overnight model runs had a coastal developing over the SE and riding up the Atlantic coast next weekend. 12Z runs of the GFS and ECMWF today have a low developing over the eastern gulf and then slowly drifting off the SE coast over the weekend, while the CMC still tracks the low up the Atlantic coast. With the high uncertainty this far out, just went with low chance pops for next weekend.
AVIATION /20Z SUNDAY THROUGH FRIDAY/. As of 115 PM EST Sunday .
VFR conditions are expected through the majority of the 18z TAF period. RIC and SBY have a chance at briefly reaching MVFR conditions after 15z Monday due to cloud bases around 2500 feet. W winds 10-15 kt with gusts to 20 kt will weaken and become light and variable at around 3 kt overnight. Higher clouds will increase by Monday morning and continue through the TAF period.
OUTLOOK . SBY has the potential to see light showers and MVFR conditions Monday night but otherwise VFR conditions expected with overcast skies. Tuesday has the potential for degraded flight conditions due to low clouds and rain across all airports ahead of a cold front which passes through the region Tuesday evening. High pressure builds Wednesday with VFR conditions returning.
MARINE. As of 235 PM EST Sunday .
Latest weather analysis reveals strong (~970mb) sfc low pressure over Atlantic Canada this afternoon. To the west, ~1020mb sfc high pressure continues to build across the region from the Ohio/Tenn River Valleys. Resultant pressure gradient has allowed for marginal SCA winds over the Chesapeake Bay and central/northern coastal waters, though winds are diminishing with gradient slackening as high builds farther east over the region. Waves generally ~2ft, seas 3-4 ft (4-5ft far N). Will keep SCA going over northern coastal waters through 7pm, with seas to slowly subside late this aftn.
High pressure slides off the Southeast coast tonight with a backdoor cold front dropping across the waters from the N. Much of the 12z/15 model suite seem to be in fair to good agreement with respect to handling of winds as the front settles south over the area Monday, w/low pressure sliding along the boundary toward the local area from the mid-south into Monday night through Tuesday. Typical minor timing differences remain during this period, but in general, ENE wind of 5-10kt is expected N of the boundary, with 10-15kt SSW wind to the S of the boundary. Seas should be 2-3ft while the boundary is over the area, with 1-2ft waves in the Bay.
By late morning Tuesday into Tue aftn, SW wind could briefly increase to 15-20kt for the lower Bay, Currituck Sound and ocean zones, which would allow for 3-4ft seas and 2-3ft waves in the lower Bay and result in some SCA winds Tue aftn. However, predominate SCA conditions not anticipated until the cold front drops across the waters Tuesday evening, with modest cold air advection occurring Tuesday night with a NNW wind increasing to 20-25kt. A second, stronger surge of CAA comes with secondary cold front (and another round of CAA) Wednesday night, w/W-NW winds increasing to ~25-30 kt. Overall, SCAs are likely for Tuesday night through early Thursday, with perhaps a lull during the day Wednesday before secondary surge of cold air arrives Wed night. High pressure returns Thursday into Friday, with improving boating conditions.

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. |
