630 AM Update...
Cloud shield hanging in over northern and central zones will
continue to slowly errode through mid morning as a stalled
frontal boundary across southern Canada begins to lift north and
this trend will continue into early afternoon. Have updated
temp/td/sky grids based on current sat pics and surface obs. No
major changes planned for current forecast.

Prev Disc...
Stalled frontal boundary over southern Quebec will lift north as
a warm front today. Expect low and mid level clouds across
northwest zones to gradually clear this morning. Aside from a
few flurries in far northern zones before daybreak....should see
a dry day with highs from the mid 30s to mid 40s north and mid
to upper 40s south.


Quiet weather will continue tonight with just variable high
clouds across the region. Low temperatures will range through
the 20s north and mid 20s to near 30 south.

Cold front will approach from the west on Saturday bringing
increasing clouds and a chance of afternoon showers. Warm
southwesterly flow ahead of the front will push high
temperatures well above normal with highs in the the lower to
mid 40s north and upper 40s to mid 50s south.


Troughing across the eastern CONUS will persist through next
week. Fast moving weather-makers will affect the CWA every
18-24 hrs or so bringing showers at times. Looking at
teleconnections, warm weather will also be in store for the
near future. All that said, there are no significant weather
events noted in the next 8 days. The deterministic models and
long term spaghetti plots are in poor agreement, however the
GEFS and Euro ensemble means are in good overall agreement.

Short wave troughs and associated ripples will move through
Sunday. Near zonal flow develops across Northern New England as
the low over northeastern Canada retrogrades. Showers will
mainly be confined to the mountains and the Midcoast as a couple
weak associated fronts traverse the region. More mixed
rain/snow showers are expected Tuesday into Wednesday- again
mainly across the north- as the next short wave dips down from

A more significant longwave system may affect the region late
next week.


Short Term...VFR today through tonight. VFR saturday with areas
of MVFR ceilings saturday afternoon.

Long Term...Periods of MVFR may affect HIE and LEB primarily on
Sunday in -SHRA/SN. Residual showers may impact HIE early
Monday. VFR expected at all other terminals during this time


Short Term...Increasing southwest flow will increase to 15 to 25
kts with highers gusts late today and lasting through much of
Saturday. Have dropped SCAs for seas and have re-issued for
winds and waves late today into Saturday.

Long Term...After a brief break Saturday night, winds/seas
approach SCA criteria once again late Sunday.


MARINE...Small Craft Advisory from 5 PM this afternoon to 5 PM EST
     Saturday for ANZ150>154.
