Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 909 PM EST Mon Jan 27 2020

SYNOPSIS. A couple of weak disturbances will cross the region in northwest flow through Wednesday morning. High pressure will build over the northern Great Lakes during the middle of the week as a cold front drops south from New England and low pressure passes well to the south near Georgia. A larger area of low pressure may approach from the Southeast U.S. Friday night into Saturday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. The main forecast updates tonight revolve around cloud cover in the moist northwest flow, with nearly-solid overcast extending into Canada and back to the northern Plains. A shortwave trough/vorticity axis is pivoting across the area this evening. After that passes, it's possible there's enough subsidence to allow some clearing with south/eastward extent (with more of a downslope influence as well). However, am not convinced we return to totally clear skies any time soon, especially given RAP RH cross sections. Will be taking a look to see if low temperatures need to be adjusted upward any as a result, not to mention there could be a slight surface wind remaining through the night.

Other than a brief sprinkle, and precipitation should be limited along/west of the Allegheny Front in the upslope regime. Moisture depth is shallow, so accumulations should be minor. It also may mean there could be a bit of freezing drizzle/mist, but do not foresee widespread travel impacts at this time.

SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/. In general, high pressure will be building toward the area through the middle of the week. Embedded in northwest flow ahead of the high, however, will be another weak disturbance Tuesday. Drier air squashes any threat for precipitation east of the mountains (with minimal chances along the Allegheny Front).

Due to the continued northwesterly winds, temperatures should trend closer to, if not slightly below normal Tuesday through Wednesday night thanks to a dry backdoor cold front.

LONG TERM /THURSDAY THROUGH MONDAY/. High pressure should keep conditions cool and mainly dry Thursday through Friday, though a disturbance passing to the south could bring some light precipitation to the Allegheny highlands/I-81 corridor Thursday.

A low pressure system over the Southeast U.S. could impact the region Friday night through Saturday night. Confidence remains low at this time as to the scale of impact. The later model guidance suggests some wintry precipitation moving into the region Friday night and Saturday morning, then a secondary low pressure system from the west bringing a chance for a mix of rain and snow showers Saturday afternoon into Saturday night. The exact track of either or both of the low pressure systems remain highly uncertain.

The possibilities of a wintry impact range from a weak system suppressed far to our south with little to no precipitation across the region, to a major coastal low tracking either along the coast or out to sea. For now, we have low end chances for precipitation advertised throughout the weekend. We will monitor trends in the guidance throughout the week and gradually focus in on a solution as we move closer to the event.

For Sunday through Monday, it appears no matter what the track and outcome of the low pressure systems are, a milder and drier pattern appear to be in store with high pressure becoming established farther to the east in the U.S.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. VFR ceilings FL040-080 will likely continue through much of the night and could occur at times through Tuesday in a moist northwest flow regime. There is a low chance (probably less than 20%) of brief MVFR conditions late tonight into Tuesday morning, mainly at MRB. It does seem like wind gusts should be diminishing for the night now, but will pick up again and gust to 15-20+ knots mid-morning (14-15Z) Tuesday.

VFR conditions are expected for Tuesday night through Friday night with NW flow becoming NE by late Thursday, generally at or below 10 knots.

MARINE. Northwesterly winds continue across the waters. There has been a a surge this evening with numerous (but generally brief) gusts up to 20-25 knots. It does appear the narrower waterways are beginning to stabilize nocturnally, confirming the brevity of the event. Will have to keep an eye on the wider waters for potential adjustments to the advisory, but will otherwise let the conditions described below prevail.

A weak disturbance will cross tonight, and with air temperatures cooling that component of mixing will not be as much of a factor. Therefore, anticipate more widespread/frequent gusts in excess of 20 knots from late this evening through Tuesday morning. The more sheltered waters of the middle and upper tidal Potomac River, Baltimore Harbor and the northern tip of the Chesapeake Bay may not have gusts quite as high or frequent due to narrower trajectories over water, so have opted to leave them out of the advisory for now. Winds may see a brief uptick over all marine zones right after daybreak Tuesday before the wind field diminishes Tuesday afternoon.

A second weak disturbance will cross tomorrow evening. Although the attendant wind field will be weaker, more of a northerly channeling component to the low-level flow could result in gusts in excess of 20 knots over the wider waters of the Chesapeake Bay.

Sub-SCA conditions are expected Wednesday through Friday night.

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.
