Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 932 AM EST Tue Jan 21 2020

SYNOPSIS. High Pressure will continue to move eastward from the Mississippi Valley, resulting in dry weather through Wednesday. The high will shift offshore during the second half of the week. Low pressure will approach from the central United States on Saturday.

NEAR TERM /THROUGH TONIGHT/. Strong high pressure located over the mid Mississippi Valley will continue to move eastward through Wednesday, delivering dry weather to the region. Aloft, a positively tilted trough extends across the area to a developing closed low over the Tennessee Valley. There's enough moisture in the trough to result in some spotty flurries west of the Allegheny Front through noon, but with a low Froude number, not expecting much, if anything, to spill into our CWA. Current satellite supports this, as clouds are beginning to thin west of the Allegheny Front. Made minor adjustments to temperatures to reflect current obs. Otherwise, previous forecast remains on track.

PREVIOUS DISCUSSION .

The closed low will dip into the southeastern states through tonight while the surface high will build toward the Ohio Valley. Some mid and high clouds may skirt by this evening, but otherwise skies will be clear. With 925mb temperatures similar to what they were Monday, expect similar high temperatures ranging through the 30s. There will be a bit less wind, though. Dew points will remain in the low to mid teens through tonight, so would expect that to be the bottom threshold for low temperatures, with the most favorable radiational cooling conditions likely in the valleys west of the Blue Ridge. Urbanized areas will be closer to the mid 20s.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Heights will rise on Wednesday as a ridge axis builds in from the west, and the surface high will move overhead. Both of these features will progress eastward Thursday. Daytime highs will moderate as a result, with upper 30s-mid 40s Wednesday and 40s to near 50 Thursday. Wednesday night will likely still be chilly with a continuation of clear skies and light winds. Mid/high clouds will be increasing Thursday and Thursday night ahead of a trough in the nation's midsection. Combined with rising dew points, Thursday night lows will be a bit warmer in the mid 20s to lower 30s.

LONG TERM /FRIDAY THROUGH MONDAY/. High pressure will be moving to our north on Friday while a mid to upper level trough deepens over the central CONUS, resulting in a mid-level cut-off low. At the surface, low pressure system will develop over the Midwest followed by an ENE track and approaching our region. This will increase the chances of precipitation over our region Friday night as the low pressure moves across the Ohio Valley. This will then develop into a coastal low Saturday into Saturday night. Rain or snow are possible as this system moves across our area between Friday night and Saturday night, with the best chance of any wintry weather west of the Blue Ridge. The low will deepen offshore Saturday night into Sunday, with possible rain and/or snow showers lingering into Sunday. Upslope snow is possible into Monday and remaining dry into Tuesday.

AVIATION /14Z TUESDAY THROUGH SATURDAY/. VFR conditions will continue through Thursday night as high pressure moves across the area. Northwest to north winds will be around 10 kt or less through tonight, then light and variable through Thursday night.

VFR conditions expected Friday with high pressure in control. Sub- VFR conditions could begin Friday night with a low pressure impacting our region and remaining into Saturday night. This system could bring rain and/or snow showers over the terminals (any chance of snow is higher at MRB at this time). A few rain or snow showers could remain into Sunday as winds increase.

MARINE. There are some gusts of 20-25 kt early this morning on waters open to the NNW fetch . generally on waters south of the Bay bridge, though there are a few sporadic reports elsewhere. Should see these winds weaken by midday as the pressure pattern relaxes a bit. However, there may be enough wind in the column to combine with northerly channeling to keep some higher gusts on the wider waters south of Drum Point through tonight, so a Small Craft Advisory will remain in effect for these locations. By Wednesday morning, winds will become lighter as high pressure moves overhead, with such conditions continuing through Thursday night.

Sub-SCA conditions are expected on Friday with high pressure in control. SCA conditions possible Friday night into Sunday with low pressure moving across our area and intensifying offshore.

LWX WATCHES/WARNINGS/ADVISORIES. DC . None. MD . None. VA . None. WV . None. MARINE . Small Craft Advisory until 1 PM EST this afternoon for ANZ532- 533-541. Small Craft Advisory until 1 AM EST Wednesday for ANZ534-537- 543.
