Area Forecast Discussion . UPDATED National Weather Service Gray ME 913 AM EST Fri Jan 17 2020

SYNOPSIS. Low pressure track northeast of the Canadian Maritimes today and tonight. Northwest continues today with cold air continuing to flow into the area through tonight. The next storm system arrives Saturday night into early Sunday with more accumulating snow likely for much of the area. Cold high pressure builds in for the beginning of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 910 AM Update . Have updated to remove the wind chill advisory and wording from products. Temperatures have increased enough over the north country to do so with wind chills around -10 to-15F for the most part this hour. Otherwise made some minor adjustments for current thermal trends.

625 AM . Added patchy blowing snow through early afternoon to the whole CWA. Reports are the usual roads near open areas are getting snow covered in the wind. I think the wind will surge a bit higher this morning, but should come down gradually after midday. Otherwise, just the usual adjustment based on current obs for the next few hours.

Previously . Strong pressure gradient will persist across the CWA today as sfc low continues to deepen to our east, and strong high pressure /~1050 mb/ slowly creeps in from the west. This will keep the NW winds going today, gusting to 30-35 mph, especially this morning. This combines with continued strong CAA will produce highs from 5-10 above in the mtns, and around 20 in the S, but daytime wind chill will range from -10 to -15 in the N to around zero in the south. Still, should see mainly sunny skies, even in the mtns by this afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. The sfc high, although weakening a bit, will shift in from the west tonight. Lows tonight will depend on how quickly decoupling occurs, as there will likely be some NW boundary layer flow through the evening, so may not see full a full rad cooling with fairly fresh snow cover, but still, the second half of the night should push the entire CWA close to or below zero, with lows in the mtn valleys possibly closing in on -20 F.

Light flow early Sat will shift to the S-SE in the afternoon, and will see clouds thicken and lower from the SW, with snow developing mid-late afternoon across all of NH and possibly wrn ME. The heaviest snow will likely hold off until after sunset. Highs will be in the teens N, to low-mid 20s S, and will likely not change too much during the afternoon.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. *** Widespread snowfall expected Saturday night ***

A progressive pattern looks to set up over North America for the next week. Looking to our west we can see the start of what will become Saturdays storm forming. A broad open leaf is visible on water vapor imagery over Colorado. This will combine with the short wave moving out of the Oakanagan valley of BC with pressure falls currently observed over eastern North Dakota.

By Saturday afternoon expect a robust low pressure system over the Great Lakes starting to spread a cloud shield into western New England. This low pressure will rapidly cross southern Ontario and then northern Maine Saturday night into Sunday as it begins to occlude.

With cold high pressure in place before the arrival of the storm expect a strong coastal front to set up as the storm approaches keeping all of the land areas below freezing with only the NH seacoast at risk for mixing. Snow will move in rapidly Saturday evening. Forecast soundings show strong upward motion through the snow growth region from 00Z-06Z Sunday, and we may see snowfall rates of 1"/hr+ during this time. With the progressive nature of the system the intense snowfall rates won't last long, limiting the accumulation. Overall expect the snow accumulations to remain right around the 6" warning threshold, with the highest confidence of exceeding that from Portland to the Lakes Region of NH and back through the Maine foothills and Augusta. Across southern NH the warming trend aloft may decrease snow ratios, while in far northern NH the CT Valley will likely be shadowed on the front side of the system. With totals hovering right around the Winter Storm Watch threshold have opted to hold off on a Watch for this update in hopes that time will allow for a better idea of the focus of the heaviest snowfall.

By Sunday morning we'll already see the backside of the system moving in. As conditions dry out aloft expect a brief period of Freezing drizzle on Sunday morning before the precipitation is able to completely come to an end. By Sunday afternoon increasing W to NWly flow will bring wind gusts to around 25-30mph across the region as the low continues to intensify and move into the maritimes.

As we move into the start of next week a very cold air mass will move south out of Canada. Arctic front will cross the region on Tuesday with snow squalls possible along the leading edge. sub zero low temperatures will drop right to the coast.

AVIATION /14Z FRIDAY THROUGH TUESDAY/. Short Term . Some lingering MVFR in the mtns and at RKD through sunrise, but should be mainly VFR thru much of Saturday. NW wind gusts in the 25-30 kt range are still possible through today.

Long Term . Snow will move in Saturday afternoon in western NH and quickly cross into ME. Expect conditions to rapidly deteriorate to IFR in snow with IFR possible at times. Conditions will improve as quickly as they dropped with VFR returning to all but the mountains. Upslope snow showers will keep the mountains in MVFR through the end of the weekend. Cold high pressure builds in for the start of next week.

MARINE. Short Term . Gales continue through much of the today as pres gradient holds, but begins to slacken this afternoon. Expect some moderate freezing spray this morning, and the again this evening. Winds gradually diminish tonight, but will likely need SCA overnight, with sub-SCA conds on Saturday.

Long Term . Another storm will cross the waters on Saturday night with rain and snow showers. Cold northwesterly flow will move in behind the system on Sunday with Gales possible. High pressure builds in for the start of next week.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Freezing Spray Advisory until 6 AM EST Saturday for ANZ150>154. Gale Warning until 6 PM EST this evening for ANZ150>154.

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.
