AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1152 AM EST Tue Jan 19 2021

SYNOPSIS. High pressure builds across the southeast states this afternoon, as low pressure moves through eastern Canada and northern New England. A dry cold front crosses the area late tonight into Wednesday morning. Low pressure tracks across the deep south Thursday and Friday. Canadian high pressure builds in from the northwest over the weekend.

NEAR TERM /THROUGH TONIGHT/. As of 1130 AM EST Tuesday .

Latest analysis indicates ~1031mb sfc high pressure centered across northern FL/southern GA, with a sfc trough along the Appalachians. Aloft, the flow is westerly, out ahead of a subtle trough moving through the upper midwest. After a cold start earlier this morning, temperatures have warmed into the upper 40s to lower 50s across most of the region under mostly sunny skies. With fairly deep mixing this aftn, a SW wind will be breezy with gusts to 20-25 mph across the area, along with fairly mild temperatures for late January: highs ranging from the mid to upper 50s over southern VA and NE NC to the upper 40s to lower 50s on the eastern shore.

A quick moving upper trough will swing through the local area tonight, which will drag a cold front through the forecast area overnight. Due to the dry airmass, and little to no moisture return today, not expecting any precip with this frontal passage, though it will be felt through gusty winds, and colder temperatures behind it. Lows tonight will range from the upper 20s across the NW, with most of the area dropping to 30-35F (upper 30s far SE).

SHORT TERM /WEDNESDAY THROUGH THURSDAY/. As of 310 AM EST Tuesday .

Strong cold air advection, and colder temps aloft tomorrow will keep temps in the low to mid 40s across much of the area, with NE NC reaching the upper 40s to around 50, despite mostly sunny skies. Then below freezing temps expected tomorrow night, as winds likely decouple with high pressure briefly pushing into the area. Have lows generally in the mid to upper 20s inland, and the low to mid 30s along the coast.

Highs Thurs 45-50 with more cloud coverage in the aftn across the south.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 620 AM EST Tuesday .

Models continue to show a series of weak shortwaves moving east across the deep south Thurs night and Fri. Both the ECMWF/CMC keep any rain chcs south of the AKQ fa, while the GFS is the outlier but has backed off a bit on the nrn extension of any pcpn (about up to the Albemarle Sound). Even the NAM keeps any pcpn well south of the local area at 84 hrs (00Z Fri). This all gets kicked south and east Fri as the next trof/cold front cross the area. Thus, will maintain the a dry forecast. Lows Thurs night 30-35 north, 35-40 south. Pt to mstly sunny Fri with highs 45-50 north, lwr 50s south.

Canadian high pressure builds in from the nw over the weekend. This will send temps blo normal with highs both Sat/Sun upr 30s-mid 40s. Lows in the 20s to arnd 30 se.

Still relatively low forecast confidence for the Monday/Monday night system, with models still having issues resolving upper low over central Ontario . as well as a strong southern stream system lifting out of the Texarkana region. GFS remains more amplified, and shows a rather significant rain event for the mid-Atlantic, potentially starting off as a wintry mix across the nwrn zones. The ECMWF and CMC, are a bit slower but eventually depict a similar mix (far NW) to rain scenario. Relatively low confidence day 7 forecast, will try a model blend this far out with the trend for a psbl wintry mix Mon morn changing to rain. Lows Sun night upr 20s-lwr 30s. Highs Mon in the 40s.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. As of 630 AM EST Tuesday .

VFR conditions across area terminals will continue through the 12z TAF period. High level cirrus clouds will slowly overspread the area this afternoon, especially across southern VA and NE NC. Then tonight, some lower level (~5000 ft) ceilings are possible as moisture increases ahead of a cold front. Breezy this afternoon, with gusts to 15-20kt across area terminals, diminishing late this aftn.

VFR conditions prevail through tonight. A cold front will cross the area late tonight/early Wed morning with little more than some passing mid clouds.

Outlook: Looking ahead, a persistent pattern keeps VFR conditions across the region through Thursday. Low pressure passes south of the region Thursday night and Friday. High pressure builds in from the NW over the weekend.

MARINE. As of 310 AM EST Tuesday .

High pressure will continue over the area today, though as the pressure gradient increases due to an approaching cold front, winds will increase briefly this afternoon to 15-20 kts over the Chesapeake Bay, and 20-25 kts over the coastal waters. While a few gusts to SCA levels are possible, the threat remains marginal, and no advisory is expected for this time period.

The bigger threat for small craft conditions will come early tomorrow morning as winds increase rapidly behind a dry cold front. Have issued SCAs for all marine zones, with strong winds lasting through the day and into tomorrow evening. On the Chesapeake Bay and adjacent rivers winds of 20-25 kts with gusts to around 30 kt are expected with seas building to 3-5 ft. Across the coastal waters, winds will increase to 25-30 kts, with some gusts to 35 kts or so possible across the outer portions of the zone for a few hours late tomorrow morning. Will refrain from Gale Warnings at this time due to the small time scale and marginal conditions. Otherwise, seas will build to 4-6 across the coastal waters.

Winds and seas come down rapidly tomorrow night, but soon build again on Thursday, with small craft conditions again possible.

EQUIPMENT. As of 630 AM EST Tuesday .

NWS Wakefield (KAKQ) radar transmitter is malfunctioning and will periodically be offline until later this afternoon (01/19/2021). The Newport/Morehead City radar (KMHX) is also offline due to a scheduled generator upgrade. Users are encouraged to access adjacent radars from Blacksburg (KFCX), Raleigh (KRAX), Sterling (KLWX), and Dover AFB (KDOX) through the outage period.

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.
