Synopsis
A warm front will lift across the region today, followed by a
cold front tonight into Saturday. Another cold front will begin
to cross the region later Sunday night.

Near term through tonight
840 am update... Band of showers has set up further south than
previously anticipated, stretching from coastal hancock county
westward into northern nh vt. This band will slowly lift
northward this morning, leaving much of northern maine dry for
another few hours. Have made adjustments to pops, qpf, and sky
cover to match the latest radar and satellite trends. No other
changes were needed at this time.

Previous discussion...

the big story today will be a warm front separating the cool
and dry air mass that had been in place over the last two days
from a very warm and moist air mass that will push into the
forecast area briefly tonight. This boundary features deep
tropical moisture originating from the remnants of tropical
storm cindy. At this time, the south edge of the warm front
features a nearly continuous line of thunderstorm activity from
iowa to upstate new york. These storms will ride northeastward
into the forecast area later this morning well north of the warm
frontal boundary and will tend to weaken as they cross the
state into a more stable environment. These initial showers are
not likely to produce any thunder. Later in the afternoon as the
warm frontal boundary creeps northward... Elevated instability
in the forecast area will increase. Surface-based instability is
not particularly likely today with the possible exception of
southwest piscataquis county. Any surface-based convection in
that location late this afternoon could be worrisome given the
helicity and low lcls. In general, cloud cover and a developing
frontal inversion low clouds ahead of the warm front will
inhibit development of storms. However, storms will develop to
the southwest of the forecast area and advect along the warm
frontal boundary into the area later this afternoon and through
the night. The bulk of the activity will be north of a line from
dover-foxcroft to houlton and slowly lift northward during the
evening. The problem is that pwats will approach 2 inches with a
deep warm cloud layer and a decent llj. With this moisture and
efficient rainfall processes, training cells could put down a
lot of rain and heighten urban and small stream flooding
concerns this evening. The warm front looks like it will be
somewhat stationary in northern zones through the night until
low pressure drifts across the area late tonight and brings a
cold front southward. Further south along the coast, heavy rains
are not much of a worry, but fog will thicken tonight. Lows
tonight will be in the mid 60s with dew points also in the mid
60s.

Short term Saturday through Sunday night
A cold front will exit downeast areas early Saturday with an
upper level disturbance crossing the region during the
afternoon. A chance of showers will occur across the region
Saturday along with a mostly cloudy morning and mostly partly
cloudy afternoon. Showers are possible early Saturday night
across northern areas. Otherwise, partly cloudy skies are
expected Saturday night. A trof crosses the region Sunday with
partly sunny skies along with a chance of showers. Low pressure
crossing northern maine Sunday night will draw a cold front
toward northern portions of the forecast area late. Showers are
possible across the region Sunday night, with the better
chances across northern areas. Otherwise, expect mostly cloudy
skies north with partly mostly cloudy skies across the
remainder of the forecast area. Temperatures will be at
slightly above normal levels Saturday, with near normal level
temperatures Sunday.

Long term Monday through Thursday
Unsettled conditions are expected across the region Monday
through Thursday. The cold front will stall across the region
Monday with a chance of showers and thunderstorms. A series of
disturbances will lift across the region Tuesday into Wednesday
in advance of an upper level trof which will then cross the
region later Wednesday into Thursday. The disturbances and
upper trof will produce occasional showers Tuesday into Thursday
along with generally partly cloudy skies. Temperatures will be
at near normal levels Monday through Thursday.

Aviation 13z Friday through Tuesday
Near term:VFR conditions this morning will deteriorate this
afternoon... Becoming ifr due to CIGS north of hul and along the
coast towards bhb. The low CIGS will reach bgr in the evening.

Embedded thunderstorms to fl350 along a warm front will be a
significant threat later this afternoon and evening. The worst
may be towards gnr and mlt later this afternoon and spread
northward and eastward in the evening. The thunderstorm coverage
will probably be fairly widespread by early this evening along
the south edge of the warm front. These storms will support
hail, but strong winds are less likely due to the stable layer
and low CIGS near the surface.

Short term: MVFR ifr conditions are expected across the region
early Saturday. Generally expectVFR conditions later Saturday
into Sunday. Variable conditions, generally ranging fromVFR to
ifr, are expected across the region Sunday night into early
Monday. Variable conditions are then expected with thunderstorms
Monday afternoon. Generally expectVFR conditions Monday night
into Tuesday, though occasional MVFR conditions will remain
possible.

Marine
Near term: although downward adjustments were made to guidance
due to very stable near-surface conditions, a tight pressure
gradient may yield a few gusts near 25 kts tonight and some seas
reaching over 5 ft. This will be just for the outer waters and
will leave the SCA in place. Fog will develop this morning and
thicken later today into tonight.

Short term: small craft advisory level seas are possible
Saturday. Conditions are then expected to be below small craft
advisory levels Saturday night into Sunday night. Visibilities
will be reduced in showers and fog Saturday into early Saturday
night. Showers are then possible again later Sunday into Sunday
night.

Hydrology
There is potential for very heavy downpours later this afternoon
and tonight along a slow moving warm frontal boundary. The
highest risk at this time will be mostly north of a line from
dover-foxcroft towards houlton. Urban and small stream flooding
are the risks as several inches of rain could fall within a very
short duration.

Car watches warnings advisories
Me... None.

Marine... Small craft advisory from 5 pm this afternoon to 8 am edt
Saturday for anz050-051.

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.
