SYNOPSIS. Low pressure will slowly move away from the area through tonight, heading northeast toward the Canadian Maritimes by Sunday. High pressure will return for the early and middle portions of next week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Low pressure presently lifting across the Great Lakes with secondary center over New Jersey, with the entire system heading northeastward slowly but surely. Lingering upper level energy as the upper trough swings in combined with low level moisture has resulted in spotty showers, and even a report of small hail. These should dwindle through early this evening, with dry conditions expected for the bulk of the region through the bulk of tonight. Exception will be the upslope region along the Allegany Front, where colder air and upslope flow will result in snow showers. However, accumulations should be minor, with totals of only an inch or two at most. Lows tonight in the 20s to lower 30s overall. If winds go calm overnight, will need to monitor for patchy fog.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/. Overall, short term will feature relativly weak west to northwest surface flow, promoting dry conditions east of the mountains and lingering upslope snow showers along and west of the Allegany Front. However, the flow will be weak and the moisture minimal, so accumulations should stay sub-advisory through the short term. A weak low pressure will pass south of the area late Sunday night and Monday, but any precip and most clouds should stay south of the area. Cold advection will result in slightly cooler readings for the next several days, but still generally a bit above normal for late January, with highs in the 40s and lows in the 20s and 30s.

LONG TERM /TUESDAY THROUGH FRIDAY/. Overall model guidance is in somewhat of agreement concerning the long term. Aloft, a quasi-zonal pattern is expected to set up over the Mid-Atlantic during the early part of next week. Back to our west, a split flow develops in the jet stream, with a zonal northern jet, and a trough developing over the Texas Panhandle in the southern stream. The resultant is multiple strings of weak vorticity being ejected eastward. While guidance has been consistent with generally quiet weather through much of next week, have kept PoPs non-zero each day given the high variability of the upper level pattern. With a lack of cold air continuing throughout next week, expect temperatures to remain near seasonable.

AVIATION /20Z SATURDAY THROUGH THURSDAY/. Slowly improving conditions through the rest of today with a drying westerly to northwesterly flow developing, though not particularly strong. CIGS gradually lifting to VFR, though spotty rain showers may bring brief restrictions should the intersect a terminal. Dry tonight through Monday night with VFR, though will need to monitor for patchy fog tonight given the relatively weak flow and ample soil moisture.

Quiet weather is expected to continue through the middle of next week as weak high pressure remains in control of the region. Mainly VFR conditions are expected through Wednesday along with a west/northwesterly wind. Wind gusts up to 25 kts are possible on Tuesday.

MARINE. Flow behind departing low pressure remains fairly weak and do not expect SCA gusts through the next day or two. Flow may increase by Monday night into Tuesday as another weak system crosses the region and then intensifies a bit off the coast, so SCA conditions will be possible by then. Winds will relax thereafter with continued quiet weather.

TIDES/COASTAL FLOODING. Tidal departures remain high, 1-2 feet, but are starting to decline now that winds have turned westerly. The next high tide this afternoon/evening should reach action stage in spots, but is not expected to reach flood stage at any gage, so no advisories are planned. Water levels should decline through tonight with the continued west to northwest flow.

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