SYNOPSIS
A clipper system will cross the area through Wednesday. High pressure will build over the region Thursday through Friday night. A strong frontal system will likely impact the region on Sunday.
NEAR TERM /THROUGH TONIGHT/
A potent upper shortwave is very evident over the Midwest, and a surface low is evident in the same region. These features will quickly make their way eastward throughout the day today and will be the focal point for unsettled weather tonight into Wednesday morning. As of mid morning, high clouds were quickly expanding northwest of US-29.
For today though, it will be remaining dry for the majority of the day east of the mountains. But, temperatures will be noticeably cooler only reaching the mid to upper 40s (30s in the mountains).
By this afternoon, the two features will be on our doorstep, and start to bring forth some moisture into our western zones.
This will be all snow for the higher elevations, or at least mostly. A few spots could see a rain mix for the first several hours, but generally this should be an all snow event along the Allegheny Front.
As we move into the evening, precipitation overspreads the entire region, especially by tonight. Again, this will generally be an elevation based wintry event, so the Blue Ridge can also expect to see some snow mix in, or perhaps even a period of all snow at the highest points along Skyline Drive and the Blue Ridge Parkway. This will especially be true after midnight as colder air continues to work its way east with the reinforcing cold front. Wouldn't be shocked to see someone pick up an inch or two from this system up there, and we could even see some isolated higher amounts. Its all dependent on just how much moisture can get squeezed out of this system.
Meanwhile, the upslope snow machine really cranks up along/west of the Allegheny front. Froude number looks to remain below 1, so thinking this will have a hard time leaking over east of the Allegheny front once we turn over to a purely upslope event.
The typical harder hit areas can expect 3 to 5 inches of snowfall, and perhaps even some isolated amounts up to 7 inches.
Thinking the bulk of the energy passes a little more south, thus keeping the highest totals south of western MD and more into our WV zones. Winter Weather Advisories will suffice for now, but will have to keep a close eye on the high-res guidance today to look for any potential upward trends.
This will be a quick hitting system however, and quickly move out of the area Wednesday morning. However, it may not do so without giving us a bit of a show west of I-95. With enough cold air in place, some snowflakes may mix in with rain towards the end of the event. Not expecting any accumulation as this occurs, but if you are up early enough, you might catch a glimpse of some snow. In a worst case scenario, colder air arrives a bit quicker and we do manage to get a light dusting, but just think that will be hard to do given pre-existing warm ground temperatures.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
As the system shifts offshore, upslope precipitation will become less intense, but could persist at times into Thursday morning. Further east, blustery and colder than normal weather prevails. Highs both Wednesday and Thursday will be below normal, with temperatures only reaching the mid 40s (upper 20s to mid 30s in the mountains).
Given the blustery winds into Wednesday night, wind chills in the mountains could get down to zero. Elsewhere, lows Wednesday night in the low to mid 20s with lighter winds.
LONG TERM /FRIDAY THROUGH MONDAY/
On Friday, upper-level ridging will be in place over the East Coast as a trough digs into the west/central CONUS. Surface high pressure to our south advances offshore with southerly flow behind it advecting moisture and above normal temperatures into the region. Dry conditions are expected through Friday and most of Saturday.
The focus of the extended will be the deep trough approaching from the west on Sunday. Guidance is currently in good agreement with the timing of the trough, placing our area under the influence of the jet ahead of the trough around Sunday afternoon and evening as it takes on more of a negative tilt. Some ensemble members also introduce some modest CAPE around this time, though the more favorable shear might be later in the evening/overnight. Probs for 24hr 1" rainfall have also been trending upward. This far out, there is significant uncertainty, but we will continue to monitor for the potential severe/heavy rain threat.
After the system exits, high pressure is expected to build in behind it on Monday, with some possible upslope precipitation along the Alleghenies.
Temperatures are forecast to be well above normal to start the weekend, approaching over 10 degrees above average by Sunday. As the cold front associated with the system moves through, temperatures drop sharply behind it on Monday.
AVIATION /12Z TUESDAY THROUGH SATURDAY/
VFR conditions are expected today, but we will again deal with SCT/BKN stratocu (FL035-050) in W/NW flow today.
Reduced CIGs/VSBYs are likely especially west of US-15 tonight into Wednesday morning as a clipper low brings a round of showers, which may even mix with snow (especially at MRB, where a period of all snow is also possible after about 03z tonight.
For BWI and MTN, a bit more uncertainty, as the majority of precip may drop to the south.
VFR conditions are expected Thursday with light westerly winds expected.
VFR conditions are expected Friday and Saturday with high pressure influencing the area. Winds will be fairly light and out of the S/SW Friday and shift more out of the SE on Saturday. As a system approaches from the west, winds may begin to pick up Saturday evening.
MARINE
Winds should remain less than 15 kts through tonight out of the W/NW. A clipper system will swing through later today into Wednesday with 25-30 kt gusts likely in its wake out of the W/NW Wednesday.
Winds begin to taper a bit Wednesday night, especially over narrower waterways, but 20-25 kt gusts likely persist over the wider waters until at least daybreak on Thursday.
Thursday brings lighter westerly winds over the waters, with no marine hazards expected at this time.
Generally southerly flow is expected Friday and Saturday, moreso southwesterly Friday and shifting out of the SE Saturday. Winds may approach SCA criteria Friday night, and SCAs will likely be needed Saturday night as winds pick up with low pressure approaching from the west.
TIDES/COASTAL FLOODING
Northwesterly flow is expected to weaken this afternoon, resulting in increasing anomalies. Some sensitive sites may approach action stage. Anomalies likely decrease Wednesday as winds increase out of the NW. Flow becomes southerly Thursday and persists through most of the weekend, increasing tidal anomalies and likely bringing sensitive locations to action by the end of the week.
