Synopsis
Low pressure will shift northeast across the canadian maritimes,
and provide a gusty northwest flow today. High pressure builds
south of the region briefly on Sunday, with a cold front moving
through Sunday night and early Monday. A brief shot of cold air
moves in Tuesday, with a moderating trend on Wednesday, as high
pressure settles over new england. The highs shifts slowly
offshore for the end of the week and provides a warming trend
with continued fair weather.

Near term until 6 pm this evening
Update... Made some change to temps dewpoint sky cover based on
latest observational trends. Also took a look at the latest wind
guidance this morning. We will see areas that were cloud covered
start to mix out into some higher gusts... But overall based on
mixing to around 40kt... I expect sub-advisory level gusts to
continue into the afternoon.

Previously...

low pressure moves off to the northeast and through the canadian
maritimes today. One more lobe of vorticity swinging around the
parent mid tropospheric low is swinging through early this
morning providing a southward moving band of rain and snow
showers. This should depart early on, likely prior to 12z. Will
leave winter storm warning up for a few more hours in the
western me mountains where upslope snow is still occurring.

Otherwise, the main theme today will be clearing and windy, with
gusts occasionally reaching 40 mph. With no real cold air mass
in the wake of this low pressure system, downsloping winds and
increasing sunshine should allow the coastal plain and portions
of southern nh to warm well into the 40s today.

Short term 6 pm this evening through 6 pm Sunday
Winds diminish this evening as a ridge of high pressure
gradually builds in. Fair weather is expected tonight with
little in the way of clouds. A cold front will gradually push
southward through the forecast area during the afternoon hours
Sunday. No precipitation is expected with this front except for
a few rain and snow showers near the canadian border. Westerly
flow ahead of the front will allow temperatures to warm
considerably, with highs well into the 50s, except 40s in the
mountains. Low probability of a couple of 60 degree readings in
southeastern nh.

Long term Sunday night through Friday
While 500 mb pattern across noam and environs continues to
trend toward +pna, it does become less stable in the latter part
of the forecast, and blocking over the WRN atlantic is
forecast to hold trough back far enough to our west to keep
things dry and mild by the end of the week the week as well.

Unfortunately, it will get cold before it gets warm as polar
vortex dives SE toward labrador Sun night into Tuesday. The
trough associated with the closed will swing across northern
new england Sunday night and Monday ans will help push a cold
front through the area. Dynamics are weak as trough show only
little amplification, and air mass is on the dry side, so do not
expect much with front as it comes through. Maybe a few shsn is
the mtns Sunday night, and outside chance of shsn or shra
toward coast late Sunday into Monday morning, but nothing which
much impact at this point. Monday will be cooler than Sunday
with highs around 30 in the mtns to 40-45 in the south, but the
coldest air will have to wait until secondary trough swings
through late Monday night, which also should come through dry,
and the coldest air will move in for Tue into Tue night, with
850 mb temps dropping to around -15c. So, highs Tuesday will be
limited to the the mid to upper 20s in the north to the mid to
upper 30s in the south.

After that it looks dry with a general warming trend as high
pressure shifts across the area Wednesday, and then settles
offshore thu-sat at least , which will bring temps above normal
for that period, with possible widespread 50s fri-sat.

Aviation 15z Saturday through Wednesday
Short term... MVFR conditions to improve toVFR this morning and
continue through Sunday. In the mountains, MVFR conditions
linger through the morning in upslope snow showers, but improve
this afternoon. Westerly winds at the sfc gust 25-35 kt today.

Diminishing winds andVFR conditions are expected tonight.VFR
conditions expected Sunday.

Long term... There is a small chc for a brief period of MVFR in
shsnra Sunday night. Otherwise, look forVFR Monday thru wed.

Marine
Short term... Gale warnings for westerly 35-40kt gusts today.

Winds and seas diminish tonight and Sunday.

Long term... Winds seas should stay blo SCA levels Monday thru
wed.

Tides coastal flooding
High astronomical tides continue today. However, developing
strong offshore flow should allow for surge values to decrease
to minimal values around the time of the early afternoon high
tide (145 pm in portland). Little if any issues are expected.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Gale warning until 8 pm edt 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.
