Area Forecast Discussion National Weather Service Gray ME 909 PM EST Mon Jan 27 2020

SYNOPSIS. Fair weather under high pressure is expected through mid to late week. The next decent chance for precipitation is this weekend when an area of low pressure coming up the U.S. East Coast passes near our region.

NEAR TERM /TONIGHT/. 9PM UPDATE . Clouds hanging around are keeping temperatures from falling much. Most areas are actually still above freezing at this hour. Will update the forecast based on the latest obs, though previous forecast seems to handle the temperatures relatively well. 530PM UPDATE . Have updated the forecast primarily to adjust precipitation chances as much of the light snow or sprinkles have tapered off. No other significant changes were needed.

ORIGINAL DISCUSSION . Some light showers have broken out across the coastal plain this afternoon as the upper level low continues to spin over New Brunswick. Water vapor imagery shows a continued NWly flow with several bursts of moisture expected to keep the clouds in at least the mountains through the overnight hours. Have increased PoP for the next few hours, but expect only a trace of rainfall as the sprinkles move through.

While mountain clouds and upslope flurries persist overnight expect the coastal plain to remain just cloudy. Those clouds will help keep temps up and low are expected to remain in the 20s across the region.

SHORT TERM /TUESDAY AND TUESDAY NIGHT/. Tuesday will remain with the northwesterly flow as the upper level low slowly moves eastwards. There may be some clearing in especially the eastern portion of the forecast area and high temperature have been raised to the 40s in this area to account for the sun. Elsewhere the low clouds continue but as the source of moisture dries up the flurries will gradually dissipate.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Overview: Surface high pressure will be dominant over New England through much of the long term period, allowing for generally quiet weather and near to above average temperatures. There is a chance for some precipitation over the second half of the weekend as low pressure develops off the U.S. east coast.

Impacts: Minimal. Low confidence of any impacts from the system late in the weekend.

Details: The rest of the work week looks to be dominated by broad surface high pressure over the northeast U.S. with any significant disturbances passing to our north and south under a split flow regime. This will keep the sensible weather to a minimum here while temperatures remain near to above average. Stayed close to the multi- model consensus for temperatures through the entire period with the exception of Thursday night as some radiational cooling can be expected with high pressure nearly overhead.

The pattern begins to change on Friday as a mid-upper level ridge builds over the western U.S. and a shortwave moves out of Manitoba and western Ontario into the Great Lakes by Saturday morning. At the same time, a system will move out of the northern Gulf Coast and make its way to the southeast U.S. coast over the same period. The southern system continues moving northeast and then intensifies well offshore, which would keep the bulk of any precipitation well away from our region. However, there are timing differences between the deterministic models, probably dependent on the amount of interaction between the two systems. It should also be noted that the global model ensembles have a wide range of possible storm tracks, ranging from well to our east to straight through New England. In summary, keeping chance PoPs through much of the latter half of the weekend until we begin to get a clearer picture of this system this week.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. Short Term . Upslope flow will continue to result in snow showers through the mountains and even a few sprinkles through to the coast over the next few hours. MVFR ceilings will continue overnight in the mountains while elsewhere the upper level low over New Brunswick will keep conditions cloudy but still VFR. Expect gradual clearing late in the day tomorrow.

Long Term . VFR conditions generally expected through the long term period as high pressure dominates along with light winds. May begin to see some MVFR conditions late Saturday, especially at PWM, RKD, and AUG.

MARINE. Short Term . Have ended the SCA as winds and seas have continued to subside. upper level low over the Maritimes will keep light northwesterly flow and cloud cover in place across the ocean zones through tomorrow evening.

Long Term . No major concerns through the rest of the week. SCA conditions are likely for the outer waters Wednesday night, primarily due to gusty winds to just above 25 kt. The current forecast suggests that SCA conditions are likely on Sunday and into early next week, but if that system ultimately tracks closer to the coast, gales would certainly be possible.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
