Synopsis
A warm front will approach from the southwest tonight and will
lift into southern new england on Friday. A cold front will push
south through the region Friday night followed by high pressure
on Saturday and Saturday night. High pressure will shift east on
Sunday. Low pressure will slowly approach from the west Sunday
night and will pass out to sea south of the region by Monday
night. Another area of low pressure will approach from the west
on Tuesday and will slowly work its way into new england on
Wednesday.

Near term /through tonight/
High pressure will shift east tonight as a broad area of weak
over-running pushes in from the west. After a mostly clear
evening expect clouds to be on the increase from west to east.

Expect the majority of the night to be dry but a stray snow
showers may edge into western zones by morning. Lows will range
from the single numbers north to the lower to mid teens south.

Short term /Friday through Friday night/
Weak over-running will result in occasional light snow or snow
showers Friday morning which will transition to rain in southern
zones during the late morning and afternoon. Snow showers in the
north may mix with a little sleet or rain in the afternoon. 12
hr QPF on the light side with just a tenth or two acccumulating
through Friday evening... So at the most only looking for an inch
or two of snow accumualtion... Mainly in the moutains. High
temperatures will range through the 30s to near 40 in the south.

Showers or mixed precip will continue Friday night as a cold
front slowly drops south through the region. Expect rain showers
and mixed precip to change over to sleet or light snow as temps
drop behing the front. Could see some additional light
accumulation in the mountains and foothills with little if any
accumulations in the south. Lows by Saturday morning will range
from the mid 20s north to the mid 30s south.

Long term /Saturday through Thursday/
Active period expected over the weekend and into next week.

A band of light mix of rain and snow will settle southward on
Saturday as high pressure builds south from canada. This
moisture will reach about as far south as southern new england
before returning northward in conjunction as a warm front on
Sunday. With a dry polar high pressure system wedged in our
area, ptype will most likely be snow over central and northern
areas with some rain in the south.

A few areas of sleet and freezing rain may come into play Sunday
night as warm air moves in aloft and boundary layer temperatures
fall to near or below 32 degrees. Low pressure will be moving
over the great lakes during this period with a secondary area of
low pressure developing in the gulf of maine by Monday.

Yet another, slightly more vigorous short wave will allow for
low pressure to move up the coastline during the midweek period.

The euro is the most progressive with this system while the
canadian and GFS hang it back further to the south.

Aviation /18z Thursday through Tuesday/
Short term...VFR tonight. MVFR/ifr ceilings/vsby Friday and
Friday night.

Long term... A brief period of ifr conditions possible on
Saturday over southern new hampshire. More widespread ifr with
possible lifr conditions over all areas Sunday night through
Tuesday.

Marine
Short term... Continuing sca's through midnight. New set of
sca's will likely be needed for Friday as southerly flow picks
up.

Long term... Winds and seas will likely reach SCA thresholds
early next week as low pressure passes south of maine and new
hampshire. Gusty northwesterly winds will lead to SCA conditions
Wednesday with a few gusts possibly into gale force.

Gyx watches/warnings/advisories
Me... None.

Nh... None.

Marine... Small craft advisory until midnight edt tonight for anz150>152-
154.

It is not checked for accuracy either by anyone at L-36.com 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.
