Synopsis for the tidal potomac and md portion of the chesapeake bay.. High pressure over ohio will build across pennsylvania and northern maryland tonight, then shift offshore of new jersey on Sunday. Low pressure will develop over the central united states and lift into the great lakes Sunday into Monday. A warm front developing east of this area of low pressure over the carolinas is expected to lift northward across the mid-atlantic on Monday. The aforementioned low will drag its trailing cold front through the region Tuesday into Wednesday. Small craft advisories may be needed Sunday night into Monday, then become increasingly likely Monday night through Wednesday.

Area Forecast Discussion . CORRECTED National Weather Service Baltimore MD/Washington DC 1051 AM EST Sat Dec 7 2019

SYNOPSIS. High pressure will build across the region through the weekend. A strong area of low pressure will then develop over the Mid- Mississippi Valley and track northeastward toward the eastern Great Lakes early next week, with warm and wet weather enveloping the region. Cold Canadian high pressure will follow that system later in the week.

NEAR TERM /THROUGH TONIGHT/. Surface analysis this morning shows high pressure centered near the Michigan/Ohio/Indiana intersection, moving east in the general direction of Pennsylvania. There is a pretty solid layer of cirrus dropping across much of the area from Pennsylvania in the left exit region of an upper jet streak diving out of the eastern Great Lakes, but it's very, very thin. So despite broken clouds being reported in surface observations, have opted to stick with sunny/mostly sunny in the forecast, especially considering this patch of high/thin clouds will quickly depart to the south and east of the area by or shortly after midday.

The high temperature forecast remains largely on track, with just a few minor tweaks made based on latest observations. This results in highs in the 40s (30s for higher terrain).

This forecast update sided with or even slightly undercut the lower end of temperature guidance for lows tonight due to anticipated ideal radiational cooling conditions as a narrow surface ridge settles between I-81 and I-95 overnight.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. High pressure will be moving offshore on on Sunday which will cause winds to become southerly. This will allow for warm and moist air advection while temperatures will climb into the mid to upper 40s over most of our area.

Clouds will be increasing late on Sunday as a weak wave of low pressure over the Carolinas moves north into Sunday night. This will increase the chance of showers over our area, especially late Sunday night. This wave of low pressure will continue to move north into our are on Monday while another low pressure system pushes NE from the ArkLaTex region into the Great Lakes as it deepens. Aloft, a digging trough will be pushing into the central CONUS and then east into Monday.

Deep moisture ahead of this system and its associated cold front, along with lift from a low and upper level jet will combine to bring rain over our area Monday into Monday night. PWAT values are between half and 1.25 inches during this period.

LONG TERM /TUESDAY THROUGH FRIDAY/. Cold front will likely be just west of the region early Tuesday, but will be heading eastward through the day and night, crossing our region by late Tuesday night. There may be some dry time before the front arrives, and southerly flow may elevate temperatures into the 60s, so there is a window of some relatively good weather possible. Timing this far out remains highly uncertain.

The front appears to be of an anafront nature, which means that most precipitation will end up falling behind the boundary in the cooler air, and some of the rain may linger into early Wednesday. That having been said, the hints of a change to snow on the back side are rather meager, so have kept any mention of snow well northwest of the I-95 corridor on Tuesday night and Wednesday.

Canadian high pressure will then build across the region for the remainder of the week, resulting in chilly but dry weather. Temperatures will be below normal, but not exceptionally so. Just a reminder that it is meteorological winter.

AVIATION /15Z SATURDAY THROUGH WEDNESDAY/. BKN250 being reported in METARs this morning as high/very thin cirrus streaks overhead in association with an upper jet streak diving out of the eastern Great Lakes. That's about all to talk about TAF-wise today, with VFR conditions and light/non- impactful N/NW winds of 5-10 kts expected through the afternoon.

Calm winds are likely at the surface tonight for most terminals, with very little if any cloud cover. Some high/mid level clouds begin to encroach on the terminals Sunday, but any precipitation should hold off until very late Sunday night at the earliest. Rain showers and subsequent restrictions become much more likely Monday into Monday night as a warm front over the Carolinas crosses the region from south to north. This warm from will be associated with low pressure developing over the Midwest, which will subsequently move across the Great Lakes through Monday night. Its trailing cold front will force a prolonging of rain chances/possible restrictions through Monday night. LLWS is possible as well as winds increase out of the SW at a few thousand feet Sunday night into Monday (30+ kts at 2 kft AGL).

Sub-VFR conditions will be likely at times Tuesday into Tuesday night as the cold front crosses the region with continued periods of rain showers likely. VFR conditions should return behind the system by Wednesday afternoon. Winds may gust 20+ knots at times through Tuesday into Wednesday, starting out more southerly Tuesday but ending up northwesterly by Wednesday behind the front.

MARINE. The Small Craft Advisory has been cancelled as winds have largely diminished. Although there's enough of a northeasterly gradient to result in a few isolated/sporadic gusts of 18-20 kts through about midday, overall the lack of frequent and more widespread gusts resulted in the decision to drop the headline.

Light to calm winds are expected this afternoon through tonight as surface high pressure ridges overhead. The high will move offshore Sunday as a warm front develops over the Carolinas well in advance of low pressure developing over the Midwest. The gradient will gradually tighten between these systems Sunday night into Monday, and may approach Small Craft Advisory levels. BUFKIT soundings show about 18-22 kts at the top of the mixed-layer in S/SE flow Sunday afternoon, about 3000 feet above the surface. The anticipated increasing cloud cover may preclude optimal mixing for these gusts to reach the surface, though channeling could accelerate the flow slightly, compensating for this. Given the lower confidence/likelihood, no headline has been issued at this time.

More widespread gusts are possible Monday and especially Monday night into Tuesday, but a strong low-level temperature inversion casts uncertainty in the magnitude of gusts reaching the surface.

Small Craft Advisories look possible Tuesday as southerly flow continues to increase ahead of an approaching cold front. They are likely by Wednesday as northwest winds pick up behind the front.
