.DISCUSSION...
KEY MESSAGE 1...Mainly dry weather continues through most of
Sunday, with an increasing risk for showers Sunday night. Near
normal temperatures through Sunday night.

Dry weather continues through most of Sunday as high pressure
moves across our region tonight, then farther east over the
North Atlantic Sunday night. Light winds tonight will mean
decent radiational cooling conditions, much will depend on how
quickly winds diminish.

Much less wind Sunday will lead to near normal high
temperatures. For the immediate coastal areas, will have to
contend with seabreezes. Thus, the high temperature for the day
could be rather late in the day along the coast, and not really
last all that long prior to sunset.

An approaching warm front and a modest midlevel shortwave may
combine to trigger some showers late Sunday into Sunday night.
There is not a tremendous amount of moisture for this system to
work with, so not expecting more than a few hundredths of
rainfall. The greatest risk remains north of the Mass Pike, and
especially towards the northern MA border into northern New
England. This is just due to proximity to the passing mid level
shortwave. Any showers are expected to quickly diminish/depart
or region late Sunday night.

KEY MESSAGE 2...Unseasonably warm, June-like conditions are
expected next week with highs mainly in the 70s to lower 80s,
though confidence is tempered by uncertainty in a potential
backdoor cold front. Otherwise, mainly dry with only isolated
showers and a period of gusty southwest winds Monday.

As advertised, summer-like weather is on the horizon as a strong
subtropical ridge builds across the Gulf. This will support
southwest flow, advecting higher moisture and temperatures into
southern New England through the upcoming week. Temperatures are
expected to be more indicative of early to mid- June rather
than early to mid-April.

That said, there are potential forecast challenges that could
lead to notable busts in temperatures, primarily related to a
possible backdoor cold front. There remains considerable
uncertainty regarding its timing and placement, which is not
uncommon at this lead time. Confidence should improve as
higher-resolution guidance resolves this feature. Ensemble
guidance highlights the uncertainty, with spreads between the
minimum and maximum temperatures on the order of 20-25 degrees.
This reflects the sensitivity of the backdoor cold front. For
now, expect highs generally well in the 70s through the week,
with a few days potentially reaching the lower 80s. The warmest
temperatures will likely occur across western portions of
southern New England, while the eastern areas have the greatest
potential to be impacts by the cooler marine air. Overnight lows
will remain mild, generally in the mid-50s to lower 60s.

In terms of sensible weather, no significant synoptic systems
are on the horizon for the coming week. However, with elevated
PWATs, even weak forcing may be enough to generate a few
isolated showers or a rumble of thunder at times. No widespread
or washout rainfall is anticipated.

On Monday, offshore high pressure and low pressure passing
through eastern Canada will tighten the pressure gradient,
increasing southwest flow. Expect increasing clouds and
moisture. A robust low-level jet will be present, with gusts of
20-30 knots possible depending on the mixing depth of the
boundary layer. Despite limited rainfall, elevated fire weather
concerns may develop Monday afternoon due to gusty winds and dry
antecedent conditions. Minimum RH values range from 45-60
percent inland and 70+ percent along the coast. May need to
coordinate with state partners on a possible Special Weather
Statement.
