Synopsis
High pressure will build across the area today allowing mostly
sunny skies but cool temperatures. A very weak upper trof will
move across the region tonight bringing some clouds and maybe a
few flurries in the mountains. High pressure moves off to the
east Friday allowing a warmer southwest flow to develop that
will continue into Saturday. Another weak cold front crosses
the region late Saturday bringing widely scattered rain showers.

A cold upper trof settles over the region Sunday with possibly
some scattered rain or snow showers and colder temperatures.

More high pressure builds in for the start of next week.

Near term until 6 pm this evening
Update: currently clear skies across all areas except in the
mountains where clouds linger. Previous forecast looks good.

Previous discussion:
a downsloping northwest flow accompanied by building high
pressure will allow mostly sunny skies today. Some clouds may
linger in the mountains though through mid morning. Temps will
be much cooler with highs ranging from the upper 20s in the
mountains to the upper 30s to lower 40s over southern and
coastal areas. Used a blend of model mav met for MAX temps.

Short term 6 pm this evening through 6 pm Friday
Tonight a weak upper short wave with very limited moisture will
move through the fast zonal flow aloft and through the region.

Nothing more than some clouds expected with this short wave. A
few flurries are possible in the mountains.

Friday a return southwest flow will develop as the surface ridge
of high pressure moves off the coast. This will mean a return to
warmer temps with highs mostly in the 40s.

Long term Friday night through Wednesday
Large scale troughing will remain in the area in some form
through late next week over the eastern conus. A short wave
will affect the region Saturday driving a weak cold front
through the northeast. This northern stream system moves ne
towards labrador allowing for more zonal wsw flow to move in
behind it.

In the dailies... A warming trend will peak on Saturday with
readings about 4-8 degrees above normal, yielding widespread
40s north and 50s south of the foothills. The cold front will
drive temperatures back a few degrees below normal values for
Sunday and Monday (normal being around 45 degrees for both
portland and concord). Chilly nights are expected for both
Sunday and Monday nights with lows ranging from the teens north
to 20s south. These temperatures will impact p-type for the
weekend... But generally we are expecting rain showers
transitioning to a rain snow mix and then just snow for the
higher terrain. Any QPF that falls will be light and
concentrated across the mountains and foothills.

By Tuesday a series of waves will approach with precipitation
chances increasing for the mid week period. Northern new
england should see another warming trend as warmer air moves in
from the southwest. Consensus shows a cold front likely moving
through by next Thursday continuing the yo-yoing temperature
trend. As for p-type, the warm air in place suggests mainly
rain. There may be some snow showers on the backside of the
system, but at this time it is too far out to assign much
significance.

Aviation 12z Thursday through Monday
Short term...VFR conditions through Friday.

Long term... Periods of MVFR may affect hie and leb primarily
for the weekend in -shra sn. Residual showers may impact hie
early Monday.VFR expected at all other terminals during this
time frame.

Marine
Short term... The northwest winds will continue to diminish today
and become more west. Seas over the outer waters remain high and
will be slow to subside below 5 ft so a SCA for seas over the
outer waters will continue today through Fri morning.

Long term... Wind gusts increase once again to strong SCA levels
late Friday into Saturday with 5-8 ft seas. After a brief break
Saturday night, winds seas approach SCA criteria once again
late Sunday.

Gyx watches warnings advisories
Me... None.

Nh... None.

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.
