Synopsis for the tidal potomac and md portion of the chesapeake bay.. High pressure will move offshore of the carolinas through tonight. A pair of low pressure systems will split the mid-atlantic to the north and south Friday, with a cold front in between crossing the region from west to east by evening. High pressure will follow for the weekend, before a stronger area of low pressure develops over the mid-mississippi valley and tracks northeastward toward the eastern great lakes early next week. Small craft advisories may need to be extended into Saturday, and may be needed again Monday night through Tuesday.

Area Forecast Discussion . Corrected National Weather Service Baltimore MD/Washington DC 400 AM EST Fri Dec 6 2019

SYNOPSIS. High pressure will move offshore from the Carolinas today. A cold front will cross the area this evening. High pressure will follow for the weekend, before a stronger area of low pressure develops over the Mid-Mississippi Valley and tracks northeastward toward the eastern Great Lakes early next week.

NEAR TERM /THROUGH TONIGHT/. High pressure is situated along the southeastern coast this morning, and areas of low pressure are over Michigan and the Arklatex, connected by a cold front. An area of mountain wave cirrus developed last evening and has slowly been eroding, although any clear skies will be replaced by mid/high clouds advancing ahead of the next system.

Moisture ahead of the southern low will intersect the Appalachians by this afternoon, but westerly (downsloping) flow at 850 mb and above will likely mean precipitation will be focused along the Appalachian crest. Warm advection will result in temperatures in the upper 40s to mid 50s, and even on the ridgetops, temperatures should be well above freezing with most of the precipitation being rain. As the cold front sinks southeastward across the area late this afternoon and evening, a few very light showers could be found along it. Used sprinkle wording east of the mountains since the chance of measurable precipitation looks very low in the lowlands.

As cold air advances behind the front, precipitation could end as a little snow on the Allegheny Front. There also could be freezing drizzle as inversion heights crash, but it would be a very brief window and thus didn't put it in the forecast. Skies will clear late tonight with lows in the upper 20s to mid 30s.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. A large/strong area of high pressure originating from Canada will quickly build east Saturday and be overhead by Saturday evening. Cold advection will result in highs in the 40s. Favorable radiational cooling on Saturday night will lead to widespread low to mid 20s, except lower 30s in the cities and by the Bay. The high will move offshore Sunday. Return flow will be offset by increasing clouds and poor mixing, with highs remaining below 50 for most.

A shortwave trough will be approaching from the nation's midsection Sunday night with low pressure developing over the mid Mississippi Valley. Moisture will stream into the area ahead of this system, and there could be additional focus of moisture along an inverted trough along the coast. Chances for rain will increase during the second half of the night. Low temperatures will be above freezing for most areas. However, some of the mountainous areas could be near freezing as the precipitation arrives, so a few pockets of wintry mix are within the realm of possibility if warm advection isn't fast/strong enough.

LONG TERM /MONDAY THROUGH THURSDAY/. High pressure will be centered over the western Atlantic on Monday. Low pressure will be moving NE from the Midwest into the Great Lakes Monday into Monday night as ir deepens. Southerly flow will advect warm and moist air into our region. This will increase the chance for showers over area for Monday.

The cold front associated to this low pressure will be approaching our region Monday night and will move across on Tuesday. Chance of showers will continue during this time and into Tuesday night. Cold air advection and residual moisture behind the front could allow for snow showers over parts of or CWA Tuesday night. Trough axis aloft will move across on Wednesday while surface high pressure starts building east and remains in control through the end of the week.

AVIATION /09Z FRIDAY THROUGH TUESDAY/. Mainly mid/high level clouds today with southwest flow ahead of an approaching cold front. There could be lower ceilings (around 5kft) and a few light showers or sprinkles as the front passes late this afternoon/early evening, but no visibility issues are expected. Winds will shift out of the northwest behind the front and could be briefly gusty to 20-25 kt.

No significant weather Saturday and Sunday with high pressure. Next weather system approaches Sunday night with lowering ceilings (possibly sub-VFR) and a chance of rain.

Chance of precipitation Monday through Tuesday night could bring sub- VFR conditions over the terminals as low pressure and cold front impact our area. Conditions should improve Wednesday when high pressure builds into our region.

MARINE. High pressure will move offshore today with southwest flow increasing. Have not changed the start times of the small craft advisories, which will be in effect for all waters by noon. Worth noting mixing may be poor and gusts sporadic. There could be a brief lull in winds early this evening with decoupling, but then a cold front will pass, winds will shift to the northwest and become gusty. Thus extended the advisory for all waters until 2 AM. Then winds will start diminishing from north to south through Saturday morning as high pressure builds.

Light winds expected Saturday afternoon through Sunday as high pressure builds across the area. Southerly flow may increase a bit Sunday night as the high departs, but looks to be sub- advisory at this time.

Sub-SCA conditions expected Monday into Monday night over the waters. SCA may be needed on Tuesday through Wednesday behind a cold front that will move across our area.

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.
