.DISCUSSION...
KEY MESSAGE 1...Mild and breezy conditions Friday ahead of an
approaching frontal system. Periods of rain develop Friday night as
the front pushes through but we`re not expecting a washout at this
time.

Fairly strong frontal wave dives SE from Ontario later Friday
bringing a period of breezy and rainy conditions. Breezy weather
will be driven by a robust south westerly low level jet that
will strengthen to 45-55 knots by the evening. Otherwise, mostly
sunny conditions should prevail at least during the morning
hours Friday. Expect thickening mid and high level clouds Friday
afternoon as well as an increasing southwest breeze. Wind
speeds increase around 10-15 mph and gusts in the 25 to 35 mph
range, with the higher end of that range more confined to Cape
Cod and the Islands which typically gusts pretty well with SW
flow (tempered by the cooler water temps). Should be a fairly
mild day with highs in the lower 50s in most areas and perhaps
as high as the upper 50s in the CT and Merrimack river valleys.
Cooler with max temps in the upper 40s over the south coast,
Cape and Islands due to persistent SW flow over the waters.

Increasing chance for POPs Friday evening and overnight as a broken
band of rain and showers moves from NW to SE. This will also lead to
decreasing SW wind gusts as the column stabilizes. As it does so, it
will act on a modest PWAT plume increasing to around 0.75-0.8
inches, which is really not that impressive. Kept PoPs at high
Likely to lower Categorical, although this doesn`t look to be a
significant precip-maker, with ensemble QPF probs still indicating
low (< 30%) probs of rainfall totals greater than 0.50". The NBM has
about a 50-50 chance of seeing greater than 0.20 inches of rain.
Given stable thermodynamics and only modest PWATs to work with, the
rainfall probs seem reasonable. May have to watch for a slowing
frontal zone though, as the orientation of the front becomes nearly
parallel to the 500 mb height contours, which could result in
lingering showers into early Saturday morning.


KEY MESSAGE 2...Breezy and unsettled through early next week.
Another round of showers Sunday night into Monday. Cooler, but still
near normal, temperatures expected Monday through mid-week.

We will still be dealing with a pesky front late Sunday into Monday
as it gets hung up by a low pressure moving over the Great Lakes.
This low pressure is anticipated to move just south of New England
late Sunday night into Monday, finally dragging this front away from
our region.

While there is a chance for some rainfall Sunday afternoon, we`re
thinking the majority of precipitation will be Sunday night. It`s
then a race between the precipitation leaving and colder air trying
to overspread southern New England. At this time, there does appear
to be a brief window where light snow is possible late Sunday night
into Monday morning. That said, this would be mainly for areas along
and north of Route 2 in MA, but could also impact the east slopes of
the Berkshires and Worcester Hills. Given the brief duration of any
snow, little to no snow accumulation is expected.

High pressure over the central Appalachians Tuesday then takes over
our weather for a brief time, before moving offshore from the Mid
Atlantic coast Wednesday.

Still not certain about the impacts from another cold front some
time late Wednesday into Wednesday night. This front looks to be
moisture-starved, so thinking mainly clouds. The next chance for
rainfall could be Thursday as a warm front tries to pass us by.

Above normal temperatures Sunday trend to below normal Monday and
Tuesday. Looking like near normal temperatures should return for
Wednesday and Thursday.
