Fxus61 klwx 221448 afdlwx area forecast discussion national weather service baltimore md washington dc 948 am est Fri feb 22 2019 Synopsis A front will stall over the southeastern CONUS through tonight as high pressure builds to the north toward new england. Low pressure developing over the middle mississippi river valley will strengthen as it moves northeastward across the great lakes into canada this weekend. High pressure will build from the northern great plains toward the great lakes and eventually into the northeast through the first half of next week. Low pressure developing over the tennessee valley could approach the region during the middle of next week. Near term through tonight The dew point gradient is the best way to discern a subtle boundary moving southward through central virginia and southern maryland this morning. The main surface front temperature gradient is draped across south carolina. Both of these boundaries will sink southward and stall through this afternoon. Plenty of high and mid-level clouds will remain overhead today shortwave energy passes through in the westerly flow aloft and the area remains in the right entrance of the jet. A northerly flow will allow for dry conditions across most areas and it will be seasonably chilly with highs in the upper 40s to lower 50s for most locations. There may be enough overrunning for some light rain, especially south of interstate 64 in central virginia. Short term Saturday through Sunday night Surface high pressure will be building to the north over upstate new york and into new england tonight (~1035 mb). This is an ideal spot to lock in some cold air near the surface, but the antecedent airmass isn't abundantly cold. Temperatures are expected to fall to around freezing for elevations above 1500 feet tonight, and across northern maryland, the eastern west virginia panhandle and northwestern virginia. Precipitation likely holds off until after daybreak Saturday, except perhaps across west-central virginia, which should allow temperatures to rise some. Still, freezing rain seems likely at least across the ridgetops along and west of the blue ridge and into western maryland, possibly the eastern west virginia panhandle Saturday morning through about midday. This is as precipitation develops in strengthening overrunning ahead of a deepening surface low over the midwest. Continued warm advection should push temperatures above freezing Saturday afternoon, though some hi-res guidance like the 00z nam nest wants to hold onto freezing temperatures over the ridges until Saturday evening. Lower elevations should see all rain (except perhaps over northern maryland near the pennsylvania border). The latest guidance has trended southward a bit with the heaviest precipitation amounts Saturday night, likely in part due to high pressure to the north nosing some drier low-level air into the region. Strong warm air advection may overcome this some, but the best upper jet forcing is displaced to our northwest closer to the parent surface low (likely to track over lake michigan Saturday night). This could help keep rainfall amounts near or a little under one inch, but even that could result in minor flooding given saturated ground and recent snowmelt, particularly over eastern west virginia this weekend. There may be a few heavier showers along the approaching cold front early Sunday morning. I could see the warm front never truly making it fully through the area given the high to the north and the parent low being so far west, but Sunday is still expected to be very mild since appreciable cold air advection lags well behind the surface front, and downsloping westerly flow compressional warming should push highs well into the 60s. Winds will likely be very gusty Sunday with a strong pressure gradient behind the front, possibly reaching or exceeding advisory criteria (greater than 45 mph).

Long term Monday through Thursday The weather pattern will be largely dominated by a broad trough aloft across eastern north america and strong canadian high pressure at the surface. As a result, temperatures will stay cooler than normal and it will be much drier than it has been lately. On Monday, a tight pressure gradient will still exist over the region associated with a deep cyclone over atlantic canada, but the winds will not be as strong like on Sunday, but still windy nonetheless. Overall, fair weather is expected much of next week but on the chilly side. Aviation 15z Friday through Tuesday MainlyVFR today. MVFR INVOF cho should lift late this morning. Cigs expected to lower to ifr by late Saturday as a warm front slowly approaches from the south, with rain overspreading the area Saturday afternoon. Some freezing rain is possible near mrb Saturday morning, if precipitation moves in quickly enough while temperatures are still near or below freezing. Winds will generally be N to NE AOB 10 kts. Vfr likely returns by Sunday afternoon with gusty W winds 35+ kts. Still windy on Monday with gusts likely in the 25-35 kt range. Winds diminish further on Tue but still breezy with gusts in the 15-25 kt range. Marine High pressure will continue to build from the north and winds should remain below SCA criteria for most of the time through Saturday night. Rain is expected to overspread the waters Saturday into Saturday night as the aforementioned boundary returns north as a warm front. Whether or not the warm front makes it through the waters before a cold front approaches from the west by Sunday morning remains to be seen, but there is moderately high confidence in gale force winds later Sunday into Sunday night in westerly flow behind the front. Marginal gales will still be possible on mon. Otherwise, strong sca conditions mon-mon evening. SCA conditions possible again on tue and wed. Hydrology Given recent snowmelt and saturated ground, three quarters of an inch to around an inch of rain may be enough to result in minor flooding issues this weekend, particularly over eastern west virginia. The overall trend has been for slightly less rain, but not so much less to completely avoid a flood threat. Despite the slightly lower QPF totals in the 00z model suite, mmefs still indicates >50% chance of minor flood at several river forecast points later this weekend.
