000 FXUS61 KAKQ 032030 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 330 PM EST Wed Mar 3 2021 .SYNOPSIS... Low pressure continues to track out to sea off the SE coast. A dry cold front moves through Thursday morning with high pressure returning to end the week. Another area of low pressure tracks well to the south of the local area this weekend. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... As of 255 PM EST Wednesday... This afternoon, high pressure is centered off the Va coastline, while low pressure continues to move out to sea off the SE coast. Locally, clouds associated with that system have moved offshore allowing for clear skies across the FA this afternoon which will continue through the night. Winds are light out of the WSW generally <5 MPH for most and 5-10 MPH over the Eastern Shore. Winds will remain light and variable tonight before gradually shifting to the WNW/NW late tonight as a cold front begins to drop south into the northern portion of the FA. Temperatures as of 2:30 PM ranged from the low to mid 50s over the Eastern Shore and the upper 50s to around 60F over the rest of the FA. Clear skies and calm winds will allow temps to drop into the low to mid 30s tonight. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... As of 255 PM EST Wednesday... A dry cold front pushes south through the FA Thurs morning shifting winds to NNW/N around 10 MPH inland and 10-15 MPH along the coast and over the Eastern Shore by late morning into the afternoon. Gusts to 20 MPH inland and 25-30 MPH along the coast and over the Eastern Shore will be possible. Mostly sunny to partly cloudy skies Thurs with the greatest cloud cover over the Eastern Shore. Any remaining cloud cover dissipates Thurs night as high pressure builds in from the NW. Highs Thurs in the upper 50s to around 60F SW, low to mid 50s in the Northern Neck, and around 50F in the Eastern Shore. Colder Thurs night with lows in the mid to upper 20s for most and upper 20s to around 30F along the coast. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... As of 330 PM EST Wednesday... Mainly dry weather for Friday night through early next week. Another upper shortwave is progged to track from the Deep South to off the SE CONUS coast from Friday night through Saturday. A strong long wave trough over eastern Canada will keep this system and its moisture suppressed well to our south (from srn SC to FL). This will also keep temps below seasonal averages through the weekend (w/ continued low-level NNW flow). Highs Sat/Sun will generally be in the mid 40s to low 50s. Lows in the mid 20s to low 30s. Our dry stretch will continue through the Long Term period with milder temperatures returning. The long wave trough will move off the East Coast by Monday. Ridging aloft will build over the regions as sfc high pressure becomes centered over the Mid- Atlantic/Carolinas. High temperatures will warm each day from the 50s on Monday to upper 60s by Wednesday. Monday morning will likely be the coldest morning as a result of a sfc high pressure being centered over the area. Lows will be in the mid 20s to around 30. Low temperatures will warm each morning and be in the 30s and 40s by Tuesday and Wednesday. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... As of 1235 PM EST Wednesday...
