The low-level flow also turns SW, which should contribute to some modest WAA by Thurs afternoon. Due to this, have issued a freeze watch for the same areas as tonight for Wed night for widespread temps 32 F and below.Įxpect a moderating trend in temperatures to set in by Thursday as high pressure shifts offshore and low-level thicknesses begin rising ahead of a building upper-level ridge. The clear skies are a contributing factor that could suggest even lower lows. Current forecast has lows reaching the mid 20s across most of inland VA, with upper 20s-low 30s closer to the coast (upper 30s right at the water). High pressure moves overhead by late Wednesday night, with winds dying down much more than tonight. Similar to today, would not be surprised to see widely scattered aftn cumulus downwind of the higher terrain. Taking all of this into account, expect an elevated risk of fire spread for Wednesday (a fire wx section will be forthcoming below soon). This leads to RHs tanking to the 15-25% (20-30% closer to the coast) range. Temps also rise a couple degrees compared to today, with highs topping out well into the 50 for most under a sunny sky. With the very dry antecedent airmass and downslope flow, dew points further plummet and could be in the single digits W of Richmond (teens elsewhere) Wed afternoon. Breezy conditions (15-25 mph, with gusts up to 35 mph) will continue across the VA and MD Eastern Shore. NW winds continue but should gradually diminish into the evening, especially for areas south and west of Richmond. High pressure will also shift eastward towards the OH River Valley by Wed afternoon. The low off of New England gradually starts pulling away (to the E) and filling in/weakening by Wednesday. SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/. The only exception is coastal Currituck OBX where the maritime influence should keep overnight temps in the upper 30s. Another freeze warning remains in effect for SE VA and NE NC - where the growing season has started - from midnight tonight until 9 am Wednesday morning. Lows will still bottom out in the upper 20s (mid 20s possible across the far NW) to low 30s. Therefore, most areas are not expected to fully decouple. The pressure gradient slackens some tonight but winds should remain elevated into Wed morning. Don't expect temps to rise much more, so highs are only expected to be a degree or two higher (upper 40s NW to lower 50s SE). Obs indicate temps are generally in the upper 40s, with some mid 40s across the VA and MD Eastern Shore and low 50s across inland NE NC. With NW flow and deep mixing, very dry air (dew points well into the teens) continues to funnel into the area. Visible satellite imagery indicates (at most) scattered CU across most inland areas where afternoon mixing has been the strongest. Wind advisory continues for the Eastern Shore through midnight. With a tight pressure gradient between the low and high, breezy-windy conditions continue across the entire FA with 20- 30 mph NW winds and gusts 40-50 mph, highest over the Eastern Shore. Given all this, the area remains in a pronounced NW-NNW flow regime. Aloft, deep upper-level trough remains over the eastern CONUS with a strong upper low just S of Long Island (almost co-located with the sfc low). To the west, a large area of high pressure (~1032 mb) is situated over the MS River Valley. Īfternoon wx analysis shows nearly stationary 988 mb sfc low pressure just off the coast of Cape Cod. NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Another cold front approaches and crosses the region late Friday into Saturday morning. Cold high pressure slowly builds back toward the region from Wednesday through Wednesday night. Breezy to windy conditions are expected through tonight. Strong low pressure remains off of New England today. Rain, mainly in the morning.Īrea Discussion for - Wakefield, VA (on/off) Help NOTE: mouseover dotted underlined text for definitionĪREA FORECAST DISCUSSION National Weather Service Wakefield VA 419 PM EDT Tue Mar 14 2023 Sat.NW winds 15 to 20 kt, diminishing to 10 to 15 kt in the afternoon, then becoming W in the evening, becoming nw 15 to 20 kt after midnight.
