An upper level disturbance will cross the area today. High
pressure builds into the area tonight and Friday. Low pressure
will pass south of the region Saturday. High pressure will build
back toward the area early next week.
Near term /through tonight/
Sfc low located south of CAPE cod is spreading pcpn into coastal
zones as of 07z. Lgt pcpn is also falling to the north in assoc with
departing wk s/wv and expect this wl come to an end in another
couple of hrs as frcg departs. What may rmn is freezing drizzle as
moisture evacuates dendrite layer and hv added to grids for ern
aroostook thru daybreak as sfc temps rmns nearly steady in the upr
Areas of fog wl occur acrs entire CWA thru 12z bfr north winds
increase in response to departing low well south of nova scotia,
bcmg patchy into mid-mrng bfr dissipating completely.
H5 trof dropping thru quebec at this time wl bring an increase in
showers drg the aftn acrs the north, tho it wl take until around
noon for moisture to return in snow growth lyr thus drizzle and/or
freezing drizzle wl be possible acrs NRN somerset initially.
Not expecting much in the way of pcpn tda with isold-sctd pops
sufficing thru the end of the near term. Highs tda wl be slightly
abv yda as airmass rmns stagnant. Mins tonight wl be cooler and
closer to seasonal norms.
Short term /Thursday through Friday/
Ridging both surface and aloft will gradually build across the
region from the west during the day Thursday. The ridging holds
thu night into fri, with low pressure to track east across the
oh valley. An isolated snow shower is possible Thu across the
crown of maine, mainly in the morning into the early afternoon,
but otherwise a dry day. The sky will be partly sunny across far
northern areas and mostly sunny to the south of the katahdin
region. Highs will range from the mid 30s in the far north in
the saint john valley to the low 40s in the greater bangor
region. Mainly clear Thu night with a sunny start to the day
fri. High clouds will increase from the west in the afternoon in
advance of low pressure moving across the oh valley. The
combination of a clear sky and light/calm wind will likely allow
some of the normally colder northwest valleys to drop to zero
to 10 above Thu night. Otherwise, mostly teens in the north and
20s toward the coast. Highs Friday will be just a few degrees
below average for the end of the march, with highs in the m/u
30s north to low 40s downeast.
Long term /Friday night through Tuesday/
Low pressure in the oh valley early Fri eve moves east and is
expected to be off the nj coast by 12z sat. The models and model
ensembles from the gfs, ecmwf, and canadian are in better
agreement this morning that the low passes south of nova scotia
with QPF amounts averaging around 0.50" along the downeast|
coast, and dropping off rapidly to the north. Most of the
precipitation looks to be in the form of snow, although it may
mix with some sleet or rain at times Saturday afternoon
along/near the coast. At this time it loos like an advisory
level event for the downeast zones, and perhaps as far north as
the central highlands, with an inch or less, and perhaps no snow
in the saint john valley. Did lower the highs some across the
downeast zones Saturday and went below guidance as it will
likely be snowing most of the day. As the low pulls away sat
night into Sun and upper trough crosses the area with isolated
to scattered rain and snow showers. High pressure builds back
into the area early next week with dry weather and seasonable
temperatures for early april on Mon and tue.
Aviation /07z Wednesday through Sunday/
Near term: ifr restrictions at all terminals thru 13z-15z before
slowly improving to MVFR as northerly winds kick in. Confidence
too low to include precip at this time though cannot rule out
isold ifr vsbys thru the course of the day as an upper level
trough swings through.
Short term: pockets of MVFR ceilings may persist into early
afternoon Thu at the northern terminals. Otherwise,VFR expected
through Fri eve. Conditions will likely lower to MVFR and
eventually lifr/ifr in snow/mixed precipitation later Fri night
and Sat at kbgr and kbhb. Conditions may lower to MVFR at the
northern terminals during the day sat. Predominately MVFR at the
terminals during the day Sunday.
Near term: winds and seas will be below SCA levels today but
increase this evening with wind gusts approaching 25kts with
marginal seas right around 5ft. Small craft advisory in effect
starting at 00z tonight.
Short term: a small craft advisory has been issued through 00z
fri. The next potential SCA will be later Fri night into Sat as
low pres passes south of the waters.
3.0" of snow was observed at caribou yesterday. This broke the
daily snowfall record for 3/28 of 2.1" set in 2005.
Today will be the 119th consecutive day with a foot or more of
snow on the ground at caribou. The record of 120 consecutive
days was set during the winter of 1968-1969.

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.
