Low pressure will approach from the south tonight and lift north
across the region Sunday. Unsettled weather and humid conditions
will continue into next week.

Near term through Sunday
9 p.M. Update... Forecast is good shape, just made some small
tweaks to the temp grids with this update. Looks like the
widespread low stratus is still about 50 to 75 miles off the
maine coast.

7 p.M. Update... Nice quiet night continues with no significant
sensible weather. Currently watching the first little area of
low stratus moving into extreme downeast coast around eastport.

This trend will continue through the overnight hours as onshore
flow becomes more pronounced as a weak coastal low over maryland
continues to move north. A coastal warm front will reach the
maine coast by morning which will be the focus for the beginning
of shower activity. The coastal fog and stratus will continue to
become more widespread after midnight and begin to push inland
by early Sunday morning.

Strong high pressure will remain over the atlantic well to the
east of new england through the day Sunday. Expect dry
conditions to persist across the region into this evening
however showers well develop across the south later tonight.

Showers are then expected to spread northward across the
remainder of the region on Sunday as low pressure moves to the
west of new england. Also expect the humidity to increase
during the day Sunday as a southerly flow develops. High
temperature Sunday will be near 80 in the north but in the low
70s in the south and coastal sections as cooler maritime air
moves inland.

Short term Sunday night through Tuesday
Bermuda high wl play dominant role in area's wx thru the middle part
of the week. 600dm upr lvl high wl keep tropical moisture streaming
into CWA on SW flow aloft as upr low deepens ovr sern u.S. Pw values
sun night wl increase to over 2.00 inches as h8 LLJ increases to 30-
40kts drg the nighttime hrs. Mins wl be hard-pressed to drop out of
teh 60s given extensive cld cvr and foggy conds at night with contd
srly flow.

By Monday aftn h5 heights begin to rise in downeast areas with pcpn
chcs lessening after about 15z in these zones building to the nw
thru the day. Highest pops present acrs the north and west on nrn
periphery of ridge and in area of elevated instability, thus hv
contd with thunder mention albeit isold chc in the aftn due to
marginal instability given higher heights than prior runs.

Ridging waxes and wanes on Tue with pops diminishing acrs most of
the CWA with the possible exception of the st. John vly where they
wl be closer to any S wvs that might ripple thru in flow aloft.

Expect another area of fog Mon night then diminishing Tue mrng with
temps rising into the 80s for inland areas. Best elevated
instability looks to be just to the north in canada Tue aftn.

Long term Tuesday night through Saturday
Ridge wl begin to weaken by mid-week upr low mvs into the prairie
provinces. Showers expected Wed with thunder possible in the aftn
mainly northwest of the katahdin region. Most likely day for showers
looks to be on thur as h5 low approaches. Expect that FROPA occurs
on Fri with upr low lingering back to the west into the early part
of next weekend.

Aviation 01z Sunday through Thursday
Near term: expectVFR conditions tonight thenVFR MVFR
conditions on Sunday.

Short term: ifr fog expected during the night and early each
morning through the period. Expect restrictions to increase to
vfr in the afternoon at bgr and points north. Tstms in the
afternoon will be a threat across northern terminals through

Near term: for winds: will use a 50 50 blend of the NAM and gfs
to initialize the grids and will reduce model wind speed by 10
percent to adjust to suppression of wind due to cold sea
surface temperature in the low 50s stabilizing the lower
boundary layer. For waves: currently the primary wave system is
long period southeasterly swell 1-2 feet 8 seconds. Expect the
long period swell to be the dominant wave system through
Sunday, however southeasterly wind wave (around 1 foot 4-5
seconds) will develop late tonight and Sunday. Will initialize
waves with nwps however will lower by 1 foot into early Sunday
to adjust for high bias in boundary wave conditions. Will
include areas of fog across the coastal waters tonight as
dewpoints increase. Total water level:
will keep the base tide anomaly along the coast at +0.10 however
there is a high bias at low tide in bangor so will adjust for

Short term: fog will be present across the waters through the
end of the week. Expect long period swell to move in Sun night
into Tue morning. Very stable layer over waters will prevent
much in the way of wind gusts through mid-week.

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.
