1225 am edt Thu aug 24 2017

Synopsis
An upper trough over the northeast, and a series of weak
surface troughs, will provide cool weather to the region through
Friday. High pressure will build slowly east from the midwest
this weekend through early next week.

Near term until 6 am this morning
1225 am update... Only minor changes to the forecast for this
time. Stratus is affecting the northernmost mountains along the
canadian border. Otherwise skies are clear and patchy fog should
form shortly in valleys and low lying areas.

945 pm update... No changes to the going forecast. Aside from a
few periods of bkn clouds in northern nh, mostly clear skies and
light winds will prevail.

650 pm update... Little change to the going forecast. Skies will
be mostly clear this evening with diminishing winds.

Previously...

at 18z... A cold front extended from new brunswick southward
through downeast maine. A series of weak surface troughs were
upstream across the great lakes. Drier air was pouring into the
forecast area in the post frontal westerly flow with dew points
now in the 50s across the area. For tonight... A mostly clear
night with patchy late night valley stratus and fog. Lows in the
50s... With mid and upper 40s across the mountain valleys.

Short term 6 am this morning through 6 pm Friday
On Thursday... Cool cyclonic flow and a passing surface trough
will result in partly sunny skies. Areas near the international
border may see some buildups and isolated sprinkles... Otherwise
a dry day with highs mainly in the 70s.

Partly cloudy Thursday night as the weak surface trough crosses
the area with some patchy late night valley stratus and fog
developing. Lows in the lower and mid 50s... With mid and upper
40s across the mountain valleys.

Long term Friday night through Wednesday
An upper level trough will cross the region Friday afternoon.

This will steepen lapse rates across the region and produce
plenty of CU mainly in the elevated terrain of northern maine
and new hampshire. There could be a couple brief sprinkles or
showers with this system, however any precipitation would be
limited, widely scattered and light.

Another trough of low pressure will approach the region for
Saturday, however the feature will mainly be to our west during
the day. So all in all, more sunshine is expected for the
first half of the weekend. It will be noticeably cooler than
during the work week with highs only in the mid 60s to lower
70s once again. There will be a light northerly breeze which may
keep effects from the sea breeze off the shoreline.

The second upper level trough will cross the weekend Sunday.

This will bring more CU to the region due to steep lapse rates,
however it will remain precipitation free.

Very little change to the forecast conditions through early next
week. The surface ridge will remain overhead and slowly modify
with a slight increase in temperatures and dew point values as
we head through next week.

Aviation 06z Thursday through Monday
Short term through Thursday night ...VFR... With LCL ifr psb in
valley stratus and fog btw 09-12z Thu and again 09-12z fri.

Long term... MainlyVFR conditions with light winds through the
period. However, some of the deeper, inland valleys will have
patchy late night fog during the period, especially in the
connecticut river valley. Radiational cooling conditions
expected and fog will likely form despite limited moisture and
lowered dew point values.

Marine
Short term through Thursday night ... Small craft conditions are
not expected tonight through Thursday.

Long term... Seas and winds will remain below SCA thresholds as a
large area of canadian high pressure builds slowly over the
waters with time.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Near term... Hanes

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
