AREA FORECAST DISCUSSION National Weather Service Wakefield VA 342 AM EST Mon Jan 18 2021

SYNOPSIS. A dry surface trough will cross the area early this morning into this afternoon. One area of high pressure slides from the Gulf Coast States to the southeast coast today through Tuesday. A second area of high pressure will build in from the west during Wednesday. Low pressure will track well south of the local area Thursday afternoon into Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 340 AM EST Monday .

Early this morning, a weak sfc trough was pushing into extrm wrn portions of the area in advance of an upper level trough over the mtns. Mainly just SCT-BKN mid level clouds were sliding across the region. Temps ranged through the 30s into the lower 40s.

That sfc trough and upper level trough will cross the area this morning into this aftn, resulting in more SCT-BKN mid level clouds. So, generally partly sunny for most of the CWA today with high temps still climbing into the upper 40s to lower 50s, due to a west wind 10-20 mph, with gusts up to 25 mph.

SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/. As of 340 AM EST Monday .

Clear or mostly clear and cold tonight, as sfc high pressure slides across the Gulf coast states toward the SE coast. Lows will range from the mid 20s to the mid 30s. That sfc high will remain near the SE coast Tue aftn into Tue night, as another weak/dry sfc trough moves across the area. Partly to mostly sunny on Tue with highs in the upper 40s to lower 50s (could be some mid 50s as SW winds will be 10-15 mph).

Another sfc high pressure area will then start to build in from the west late Tue night into Wed morning, with the high then building into and over the region Wed aftn into Wed night. Lows Tue night in the upper 20s to mid 30s. Highs on Wed will range through the 40s to near 50. Lows Wed night in the mid 20s to lower 30s.

LONG TERM /THURSDAY THROUGH SUNDAY/. As of 300 AM EST Monday .

End of the week now looking to remain dry across the local area. 00z/18 models now nudges the front and any light lingering precipitation south across the Carolinas on Thu. A series of weak shortwaves then push across the deep south Thu-Fri. The 00z GFS does try to bring some light overrunning pcpn across the VA- NC border south into the Carolinas Thu night, but the ECMWF/CMC are both drier across the local area, confining any rainfall well south of the area. Given the continued trend toward a drier solution, have maintained a dry forecast through the upcoming work week. Canadian high pres then builds in from the nw for next weekend, eventually pushing offshore early next week. The high dominates thru Sun with the next system approaching from the west Sun night into Monday.

Highs Thu/Fri mid 40s-lwr 50s. Lows Thu night in the 30s. Lows Fri night mid 20s-lwr 30s. Colder next weekend with highs in the upr 30s-lwr 40s with increasing clouds Sun.

AVIATION /08Z MONDAY THROUGH FRIDAY/. As of 135 AM EST Monday .

VFR conditions will prevail at the TAF sites today into Tue morning. SCT-BKN mid/high level clouds are expected to move across the region through this aftn. WSW winds will increase to 10 to 15 kt with gusts to around 20 kt this aftn. Clear or mostly clear sky this evening into Tue morning with just SCT high clouds.

OUTLOOK . A persistent pattern keeps VFR conditions through Wed night. Low pressure passes south of the region Thu aftn into Fri.

MARINE. As of 300 AM EST Monday .

Latest Obs reflect W-SW winds across the waters this morning. Winds will increase to ~15 kt in the Bay and ~15-20 kt offshore later this morning, as gradient tightens slightly ahead of an approaching upper trough and attendant weak surface reflection/front. That weak front crosses the waters this afternoon, with winds increasing to 15-20 kt. Short-lived SCA headlines (6-9 hrs) have been issued for the Bay, Sound, and lower James River in response to expected weak cold air advection later today into tonight. A few gusts to ~25 kt possible over the coastal waters, but given brief duration and with significant seas remaining in the 2-4 ft range, will hold off w/any headlines over the open ocean zones for now.

Winds diminish tonight with high pressure building south of the waters, with conditions then forecast to remain below SCA thresholds from Monday evening through midweek, when another front is expected to cross the region with increased winds. Waves generally in the 1-3 ft range with seas forecast to remain 2-4 ft through the upcoming week.

EQUIPMENT. As of 135 AM EST Monday .

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.
