115 am edt Wed mar 29 2017

Weak low pressure will cross the area this evening. An upper
level disturbance will move across maine Wednesday afternoon and
evening. High pressure builds into the area Thursday into
Thursday night. Low pressure is expected to pass south of the
area Saturday.

Near term /through today/
120 am update...

sfc low to the south of CAPE cod is spreading pcpn into coastal
zones at this hour. Light snow showers hv all but exited ern
zones ATTM and hv updated pops to account for both areas. Expect
rain along the immediate coast, though cannot rule out sleet as
colder air gets pulled in on nrly flow and eventually changing
to snow by mrng. Latest hrrr and rap hv fairly good handle on
pcpn but may be just a tad too far south for the ovrngt and wl
keep an eye on mvmnt for next update. No other chgs needed at
this time.

Previous discussion...

h5 trof across quebec will move southeast toward northern maine
tonight and then across the region during Wednesday. Short wave
energy ejecting around the upper trof will cross the region
this evening while a southern branch short wave passes to south
of the gulf of maine later tonight. Some light precipitation
associated with the northern short wave will cross the region
into early this evening, while another band of light
precipitation skirts the downeast coast a little later tonight.

Precipitation across the north will be in the form of some light
rain/snow showers this evening, possibly mixed with a bit of
sleet, before ending in the form of snow later tonight. There
could be an inch or so of accumulation, especially across the st
john valley. Across downeast, expect mainly rain showers. Skies
will remain cloudy overnight with soundings showing plenty of
moisture below h7. The abundant cloud cover will once again keep
temperatures from falling too much from current afternoon
readings with upper 20s north and lower 30s downeast.

H5 trof crosses the region Wednesday. Soundings still showing
quite a bit of moisture between h8 and h9 level so will still be
looking at quite a bit of cloud cover across the area but
certainly may see a few sunny breaks from time to time. Still
couldn't rule out a brief rain/snow shower as the upper trof
crosses the region. Temperatures on Wednesday should be a good 5
to 10 degrees warmer than today.

Short term /tonight through Friday/
Sct sn shwrs msly ovr NRN ptns of the region will gradually
diminish Wed ngt into Thu as the upper trof slowly moves E of
the region. Winds will be fairly brisk out of the nnw durg these
pds. The airmass behind this system is msly non-arctic, so
temps... Spcly hi temps should recover closer to climo values,
spcly by fri, when msly sunny skies and lgtr winds are xpctd.

Long term /Friday night through Tuesday/
Longer range models tdy are in better agreement in showing some
impact with ovrngt and mrng snfl for msly cntrl and spcly
downeast ptns of the region later Fri ngt into Sat and only a
grazing impact to NRN ptns of the region as low pres from the
mid atlc states moves E to well S of nova scotia. MAX pops were
constructed in this manner wil likely pops ovr SW ptns of the
region to mid chc pops ovr the far N and ne. A little to erly to
speculate about sn amts with this system attm, but a consensus
total QPF with this event would not likely exceed wntr wx adv
thresholds ovr downeast areas, and that's if the event were all
sn with decent liq to sn ratios. Steady sn/rn will taper to sct
rn/sn shwrs Sat aftn and eve, contg as isold to sct ngt/erly
morn sn shwrs and late morn to aftn rn/sn shwrs on Sun as an
upper trof crosses the region. Mon and Tue ATTM looks to be fair
with near seasonal temps.

Aviation /05z 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 to long term: MVFR clgs for NRN taf sites andVFR for
downeast sites xpctd Wed ngt thru Thu morn, thenVFR all sites
thu aftn thru Fri eve. The next chc of MVFR/ifr clgs/vsbys for
our TAF sites will be late Fri ngt into Sat with sn/mixed
precip. Conditions should then improve toVFR ovrngt Sat and
then cont so on sun.

Near term: winds/seas will remain below SCA levels through

Short to long term: the next sig chc of SCA conditions will be
wed ngt and Thu with llvl cold advcn nnw wind pattern. Aftwrds...

winds an seas will be at marginal or below SCA thresholds with
the greatest uncertainty Fri ngt into Sat depending on the track
and intensity of sfc low pres tracking E from the mid atlc
states into the open N atlc well S of nova scotia. Kept close
to ww3 WV guidance for fcst WV hts.

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.
