.DISCUSSION...
.DISCUSSION...

KEY MESSAGE 1... Breezy, warm, and dry day with elevated fire 
weather potential this afternoon.  

Cold start this morning for many of us as a few additional hours of 
radiational cooling took place with less cloud cover than high-res 
guidance initially advertised. Coldest spots this morning are 
interior valleys with lows in the lower 30s. Quick warm up this 
morning as 850mb temps soar from 0C to +6C by this afternoon. Given 
the expected well mixed boundary layer up to 800mb with full sun, 
expecting high temperatures in the upper 60s to low 70s in the CT 
and Merrimack River Valleys. Coolest temps will be found along the 
immediate south coast will be coolest in the low to mid 60s. Good 
mixing also leads to a gusty day; with a 25-35kt 850mb jet overhead, 
expecting to mix down gusts of 25 to 35 mph. This, combined with the 
drier air (RH values down to 25-30 percent) has led us to issue a 
Special Weather Statement for elevated fire weather potential 
covering all of southern New England with the exception of Cape Cod 
and the islands. 

KEY MESSAGE 2... Warmer on Tuesday with a chance for showers and 
thunderstorms across far northwestern Massachusetts. 

Cold front slowly advances toward our CWA through the day on 
Tuesday. At the same time, high pressure continues to build over the 
Atlantic. The result will be a gusty SW winds and even warmer 
temperatures away from the marine modified airmass towards the south 
coast. 925T on the order of +17C/+18C should allow highs to reach 
near 80 in the lower elevations northwest of I-95. The gusty 
southwest winds will hold highs in the 60s near the south coast, 
Cape and Islands. It is possible that Nantucket does not even break 
60 degrees! Bufkit soundings support southwest wind gusts of 25 to 
35 mph with a few gusts of 40-45 mph possible towards the upper Cape.

Mainly dry weather prevails Tue as most of the synoptic scale 
forcing will remain well to our west in the vicinity of the cold 
front. Still see at least a low risk for a thunderstorm or two 
across western Massachusetts with CAPE values increasing to around 
1000 J/kg Tuesday afternoon.  

KEY MESSAGE 3...Unsettled for the midweek timeframe with multiple 
chances for showers and embedded thunderstorms. 

A slow moving cold front approaches the region from the west on Wed. 
Still some timing differences...But we do expect a band of showers 
to overspread the region from west to east as the day wears along. 
This may take until mid-late afternoon to reach the I-95 
corridor...but again the timing still needs to be worked out. There 
might be an embedded t-storm or two as well...But instability does 
not look to be high enough for any severe weather. 

This cold front slowly sags south of our region Wed night into Thu 
bringing cooler temps. In terms of the potential for a secondary 
area of low pressure, the trend amongst guidance has been for a 
solution further to the south of the CWA and thus more of a glancing 
blow.  The exact track of this low will have a significant impact on 
temperatures during the day Thu depending on if we see rain or end 
up mainly dry.

KEY MESSAGE 4...Turning sharply cooler late in the week and into the 
weekend. 

The long range ensembles are in good agreement in an upper trough 
with below normal height fields re-establishing itself Fri into the 
weekend. Modest westerly flow this time of year coupled with the 
strong May sun angle should keep high temps near or just slightly 
below normal though. Highs should still mainly be in the 60s. The 
night/s will be potentially cool though with lows in the 40s and 
potentially some 30s along with a frost risk if we have enough 
clearing.

As for precipitation chances...some shortwave energy with the 
associated upper trough/cold pool aloft may bring the potential for 
a few showers at times. However...not expecting a washout with 
plenty of dry weather expected as well over this time.&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent. 
High - greater than 60 percent.

06z TAF Update...

VFR conditions continue through the next day. SW winds increase
later this morning and especially in the afternoon with gusts 
on the order of 25 to 35 knots with perhaps a few gusts near 40 
knots towards the typically prone locations near KFMH. The gusts
gradually diminish this evening...but still expect sustained 
S-SW winds of 5 to 15 knots overnight with a few gusts up to 20 
knots persisting.

KBOS Terminal...High confidence in TAF. 

KBDL Terminal...High confidence in TAF.

conditions, the Small Craft Advisory has been extended into 
Tuesday for the outer waters and expanded into the inner waters
this afternoon. There is also a chance for near-gale force winds
across Buzzard's Bay as well as Nantucket Sound this afternoon.
Additional SCAs will likely be needed Tuesday.
