Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1001 AM EST Mon Jan 20 2020

SYNOPSIS. A large area of high pressure will move from the northern Plains during the first half of the week, centered overhead by Wednesday. The high will move offshore during the second half of the week, then low pressure will approach from the central United States for Saturday.

NEAR TERM /THROUGH TONIGHT/. Arctic surface high pressure 1044 mb over the northern plains will continue to expand east and dominate the weather across the eastern US through Thursday. Except for the far western upslope areas . conditions today will features breezy conditions and cold temperatures under sunny skies. Temperatures will average below seasonal normals today with mid 30s DC and lower 30s Baltimore areas.Wind chill readings this morning continue in the teens to lower 20s east of the Blue Ridge . with even single digit wind chills at times this morning at higher elevations west of the Blue Ridge. Northwest winds will continue gusty through this afternoon ranging from 20 to 30 mph. Upslope flurries will continue through around noontime but should taper off as moisture levels decrease through the afternoon there.

Tonight as the surface high build east, excellent radiational cooling will exist under clear skies although northwest winds will continue overnight helping to promote some mixing. Lack of snow cover other than along the western slopes will help keep temperatures from tanking too far..but a few single digits could occur in some of the sheltered valley locations across western areas.

Previous Short/Long term discussions follow .

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/. Upper troughing will gradually lose its influence Tuesday and Wednesday, allowing the surface high to spread eastward. Ridging aloft will be overhead by Wednesday. Dry conditions are expected, and other than a batch or two of passing cirrus, skies should be mainly clear as well. Daytime highs will moderate a bit each day, with 40s becoming common again by Wednesday. Winds will become less of a factor as well. Lows will respond more slowly given favorable radiational cooling conditions continuing. Teens and 20s are expected both Tuesday and Wednesday nights.

LONG TERM /THURSDAY THROUGH SUNDAY/. High pressure will be in control on Thursday while mid to upper level trough deepens over the central CONUS, resulting in a mid- level cut-off low by Friday. At the surface, low pressure system will develop, but it is uncertain on location as deterministic and ensemble means develop it either over the Midwest or over the Tennessee Valley. This is followed by an ENE track that will increase the chances of precipitation over our region Friday night. The low pressure will then either move over us from the SW or will transfer its energy from the Great Lakes into a coastal low on Saturday. Either solution brings precipitation in form or rain or snow (mainly over higher elevations) between Friday night and Saturday night as the low deepens offshore. The low will move away from us Saturday night into Sunday with some lingering precipitation. Sunday night into Monday guidance suggests a shortwave trough could bring us some additional precipitation.

AVIATION /15Z MONDAY THROUGH FRIDAY/. VFR conditions expected through Friday. Gusty northwest winds will continue through mid afternoon, with peak gusts in the 20-25 kt range, then by late afternoon wind gust will diminish. Northwest winds tonight under clear skies.

MARINE. Small Craft Advisory conditions continue on all waters through noon. Gusty northwest winds continuing this afternoon. Blowout tides (-1 ft MLLW or lower) this morning for the northern Potomac and the upper reaches of the Chesapeake Bay. Wind gusts over the Upper Tidal Potomac are marginal for SCA conditions, but the middle/lower Potomac continue to quite gusty.

As the strong Arctic high pressure continues to build into the region, a tight pressure gradient across the Bay will result in continued gusty northerly winds tonight, with the advisory continuing for the wider waters south of Pooles Island, including the lower tidal Potomac. The high will be overhead by Wednesday, with light winds prevailing through Wednesday night.

Sub-SCA conditions expected Thursday into late Friday with high pressure in control.

LWX WATCHES/WARNINGS/ADVISORIES. DC . None. MD . None. VA . None. WV . None. MARINE . Small Craft Advisory until 10 AM EST Tuesday for ANZ531>534- 537-539>543. Small Craft Advisory until 6 PM EST this evening for ANZ530- 538. Small Craft Advisory until noon EST today for ANZ535-536.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
