604 am est Thu jan 18 2018

High pressure will build across the region today and Friday.

Low pressure will track north of the region Saturday.

Near term through tonight
6am update... Added patchy freezing fog for portions of southern
penobscot county as well as much of hancock and washington
counties early this morning. A sharp and shallow inversion has
formed and will take a few hours for surface heating to
eliminate it.

Previous discussion...

the ridging will build from the southwest today with a good
deal of sunshine in southern zones. North of the katahdin
region, there's enough h925-h850 moisture for some CU sc fields.

Without much cold air advection behind the departing low, highs
will reach the mid to upper 20s for most of the area. The coast
will see some readings in the lower 30s. A weakening cold front
will approach from quebec later today. No measurable
precipitation is expected, but a few flurries cannot be ruled
out. The cold front will end up in saddle point structure in
northern zones tonight between ridging in the SE us and quebec.

The front will gradually creep southward later tonight as a weak
h500 trough arrives from the great lakes region. There's won't
be any markedly colder air behind the front. The primary impact
of the frontal crossing tonight will be clouds that prevent deep
radiational inversions forming with light winds.

Short term Friday through Saturday night
High pressure will cross the region Friday, with a developing
warm front to the west. Expect mostly cloudy skies across
northern areas Friday, with partly cloudy skies downeast. Low
pressure will track north of maine Friday night through
Saturday. The low will bring light snow to northern portions of
the forecast area Friday night through early Saturday with light
snow accumulations expected. Across downeast areas, clouds will
increase Friday night through early Saturday then decrease
later Saturday. Temperatures will be at near normal, to slightly
above normal, levels Friday. Above normal level temperatures are
expected Saturday.

Long term Sunday through Wednesday
A cold front will cross the region early Sunday, with high
pressure building across the region late. Snow showers could
accompany the cold front across mostly the north and mountains
early Sunday. Otherwise, generally expect partly cloudy skies
across the region Sunday. High pressure exits across the
maritimes Monday while low pressure crossing the great lakes
draws a cold occluded front toward new england. Cloud cover
will increase Monday, with increasing snow chances Monday night.

However, uncertainty still exists regarding how rapidly
precipitation is able to expand against retreating high
pressure. The primary great lakes low will track northwest of
the region Tuesday drawing a cold occluded front across the
region. Uncertainty also exists regarding the timing of the
cold occluded front Tuesday into Tuesday night along with
whether a secondary low develops along the front. Expect snow
across the region early Tuesday. Warmer air being drawn north
should then allow the snow to transition to a wintry mix, from
south to north, across much of the forecast area Tuesday
afternoon through early Tuesday night. Precipitation could
possibly transition to all rain across downeast areas later
Tuesday, particularly closer to the coast. If a secondary low
were to develop along the front and limit the northern extent of
warm air, precipitation across northern areas could remain
mostly snow. Exact precipitation types amounts Tuesday remain
uncertain at this time. The initial cold occluded front will
exit across the maritimes Wednesday, with a secondary cold front
crossing the region later Wednesday. Expect a chance of snow
showers Wednesday, with the better chances across the north and
mountains. Otherwise, generally expect mostly cloudy skies
across the north and mountains with partly cloudy skies
downeast. Temperatures will be at above normal levels Sunday
then again Tuesday Wednesday. Near normal level temperatures
are expected Monday.

Aviation 11z Thursday through Monday
Near term:VFR conditions are expected outside of some MVFR
cigs that will affect terminals from pqi northward.

Short term: generally expectVFR conditions across the region
Friday. MVFR ifr, with occasional lifr, conditions are expected
across northern areas later Friday night through early
Saturday, with occasional MVFR conditions possible downeast.

Occasional MVFR conditions are possible across the north and
mountains Saturday night into Sunday, with generallyVFR
conditions downeast.VFR conditions are expected across the
region Monday, with MVFR ifr conditions developing Monday night.

Near term: no significant weather is expected. Northerly winds
will increase this evening with some gusts up to 20 kts.

Short term: conditions are expected to be below small craft
advisory levels Friday through early Friday night. Small craft
advisory conditions will develop later Friday night then persist
through Saturday night. Wind gusts could approach gale levels

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
