SYNOPSIS. High pressure slowly builds to the south through Sunday night, then slides farther offshore on Monday. A storm system approaches from the southwest Monday night then tracks off the Mid Atlantic coast on Tuesday.

NEAR TERM /THROUGH FRIDAY/. Another cold night is on tap for Northern and Downeast Maine. The combination of a mainly clear sky, light winds, and snowpack will allow for good radiational cooling conditions tonight. Lows across the north are expected to range from 15 below to 25 below zero, and 5 below to 10 below zero as far south as the Upper Penobscot Valley, and interior Downeast Maine, including the greater Bangor region. Fortunately, winds are expected to drop off quickly after sunset, so wind chills are not expected to be a significant issue.

Mid level ridging builds into the area on Friday and allows warm advection to commence. This results in milder afternoon temperatures Friday, although still several degrees below normal for this time of year. Friday's highs are expected to range from the upper teens to near 20 north and low to mid teens central and Downeast under a mainly sunny sky.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/. A northern stream shortwave trough passes Friday night, however with the core of the energy associated with this system remaining over Quebec it should remain dry, except for maybe some stray flurries late over the portions of the North Woods. Lows Friday night should be a few degrees above normal.

WNW-W flow aloft Saturday and Saturday night. Some weak shortwaves embedded in this flow could again bring some flurries to the North Woods, but it should mainly remain dry with fair conditions over northern and eastern Maine. Highs on Saturday should be around 5 degrees above normal, with most locations getting at or above the freezing mark. Lows Saturday night should be around 5-10 degrees above normal.

The flow aloft becomes WSW on Sunday in response to a weak shortwave moving from the Great Lakes into the Mid-Atlantic States and a northern stream trough moving into Ontario. With no shortwaves though progged to move through our region, it should be dry. Highs on Sunday will be around 10 degrees above normal - ranging mainly from the upper 30s to lower 40s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. SW flow aloft over the region Sunday night-Monday as the afore mentioned northern stream trough shears out, and its main energy stays well to the NW/N of the region. So it should continue to remain dry as a result.

A 700-500 hPa shortwave passing coupled with weak low level warm advection will bring an increase in cloud cover Monday night and possibly some light snow to far SW zones late.

The models then differ on the details on low pressure systems that should impact Northern and Eastern Maine Tuesday/Tuesday night and again Wednesday night-Thursday. For now the GFS seems to be an outlier with its more northern and western low track for both systems when compared to both GEFS and EPS ensemble members and the operational CMC and ECMWF. The forecast during this time frame is weighed more towards a blend of the GEFS mean and ECMWF which are fairly similar and do not deviate much from the NBM in terms of individual gridded fields.

Based on this blend the following is currently forecast for sensible weather from Tuesday-Thursday. Pops were capped at chance due to a combination of higher than normal model uncertainty and the natural inherent uncertainty in the day 5-7 time frame.

For now it appears that the low levels should be sufficiently warm to support a spotty light rain over most of the area Tuesday, except for a mix of rain/snow over portions of the North Woods and Saint John Valley and the higher elevations around Mt Katahdin. Precipitation becomes transitions to scattered snow showers (rain/snow showers Bangor and immediate coast) from NW to SE Tuesday night as cooler air builds in at the low levels behind the initial departing low.

For now it appears Wednesday should be mainly dry, but an isolated snow shower or flurry cannot be ruled out across the North.

The second low should bring a chance of snow everywhere by late Wednesday night. The snow should continue on Thursday, probably mixing with or changing to rain across the Bangor Region and most of Downeast Maine.

For now it appears that the system for Tuesday should be the weaker of the two systems. At this time there is too much uncertainty to specify what if any impacts the system for Wednesday night/Thursday could have on the region.

Temperatures should be above normal Sunday night-Wednesday. Then near normal on Thursday (depending on exact track of the storm system).

AVIATION /20Z THURSDAY THROUGH TUESDAY/. NEAR TERM: VFR through Friday. Gusty NW winds will subside early this evening and then become light SW tonight. SW winds 5 to 10 kt are expected on Friday.

SHORT TO LONG TERM: Friday night-Monday. VFR, with possible exception of a low chance of MVFR in any stray snow shower late Friday night/Saturday over the North Woods. SW-W winds G15-20KT possible, with the best chance during the afternoon each day.

Monday night-Tuesday. MVFR or lower possibly developing late Monday night/early Tuesday morning and then continuing through the day on Tuesday.

MARINE. NEAR TERM: Winds/seas are expected to generally remain below SCA levels through Friday. A Freezing Spray Advisory has been issued this evening through late tonight. Visibility is expected to be unrestricted through Friday.

SHORT TO LONG TERM: SCA conditions are probable on the coastal ocean waters and possible on the intra-coastal waters Friday night and Saturday morning. Sub-SCA conditions are then predicated on all waters from Saturday afternoon through Tuesday as a light to occasionally moderate pressure gradient settles over the waters.

CAR WATCHES/WARNINGS/ADVISORIES. ME . None. MARINE . Freezing Spray Advisory from 7 PM this evening to 5 AM EST Friday for ANZ050>052.

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.
