.WHAT HAS CHANGED...

There is a marginal risk for a strong to severe thunderstorm
this evening, mainly across western MA and CT.

&&

.KEY MESSAGES...


- Scattered showers and thunderstorms this evening with a strong to 
severe storm possible over western MA

- Unsettled weather continues into Wednesday and Wednesday Night

- Milder and unsettled pattern later this week brings showers from 
time to time along with warmer temperatures for inland locations. 


&&

.DISCUSSION...
KEY MESSAGE 1...Scattered showers and thunderstorms this evening 
with a strong to severe storm possible over western MA

Short-wave energy embedded within larger scale zonal flow aloft
will help trigger showers and thunderstorms this evening over 
western MA/CT. The latest Convective Outlook from The Storm 
Prediction Center places western MA and CT in a marginal risk 
for severe storm with a general thunderstorm risk elsewhere in
southern New England.

The overall strength of synoptic forcing for ascent in the 
atmosphere will be on the weak side tonight. Furthermore, 
instability will be limited to the tune of 250-500 J/Kg of 
MLCAPE. While sufficient for thunderstorm development, these 
numbers do not present an alarming scenario for severe weather. 
Deep layer shear will be strong with 40-50 knots of shear in 
the 0-6 km layer. Thus, we have the ingredients needed for a
period of convection. 

If we consult the latest suite of hi- resolution model 
guidance, we find that 00-06Z (8PM-2AM), will be the best 
opportunity for thunderstorms across southern New England. Hi- 
res guidance keeps the most robust activity mainly along and 
north of the I-90 corridor. CSU ML probabilities give a 5-10% 
chance of severe thunderstorm wind gusts or large hail for 
western MA. Further east, lightning and periods of heavy 
rainfall would be the most likely hazards. Expect thunderstorm activity
to wane after midnight as instability diminishes. 

KEY MESSAGE 2...Unsettled weather continues into Wednesday and 
Wednesday Night

A wind shift to the west/southwest early Wednesday will support 
another mild afternoon in southern New England with many 
locations reaching the upper 60s to low 70s. The presence of a 
frontal wave moving over The Northeast will continue to keep 
things unsettled with intermittent periods of showers expected 
during the day Wednesday. A lull in shower activity is expected
Wednesday afternoon, but a cold front sagging south will 
support an additional round of showers Wednesday night into 
Thursday, mainly along and south of the I-90 corridor. Latest
model guidance resolves the most shower activity over the south
coast of MA and RI. Chillier temperatures settle in Wednesday 
night with lows temperatures falling to the 30s by Thursday 
morning.

KEY MESSAGE 3...Milder and unsettled pattern later this week brings 
showers from time to time along with warmer temperatures for inland 
locations. 

Beyond Wednesday we're in for a big cooldown as 1040mb high pressure 
moves into Nova Scotia and surface winds veer to the northeast 
pushing a cold front the rest of the way through the region. This, 
combined with stubborn low clouds will keep high temperatures very 
cold compared to Wednesday, in the upper 30s and low 40s. This will 
be a 30 degree difference in high temperatures for some locations! 
The roller coaster continues on Friday as the front lifts back to 
the north bringing warmer temps in the 60s and even some 70s by the 
weekend. That being said, it remains a very chaotic and dynamic 
pattern with SNE sandwiched between a subtropical ridge and east 
coast trough so confidence in the temperature forecast is low to 
moderate. Same with exact timing and placement of any rainfall 
associated with these frontal passages and passing shortwaves. A 
generally unsettled pattern with scattered rain showers looks to 
hold on through the early part of the weekend before a more 
appreciable front and mid level trough move through around 
Sunday/Sunday night.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Low - less than 30 percent. 
Moderate - 30 to 60 percent. 
High - greater than 60 percent.

18Z TAF Update...Moderate confidence

Through 00Z...High confidence in flight categories. Low confidence 
in timing and location of rain showers.

Low clouds associated with a backdoor cold front will support 
IFR/LIFR ceilings at BOS/BED for the rest of the afternoon. South 
and west of the cold front, VFR conditions prevail with steady 
southwest winds. Intermittent periods of showers expected mainly 
north of ORH and BED, but a few showers will be possible elsewhere.

Tonight...Moderate Confidence

Steadier RA moves in from west to east after 00Z with -TSRA possible 
through 06Z. Areas of IFR/LIFR ceiling near BOS/BED retreat east 
after 06Z with improvements to MVFR between 06-12Z. VFR 
conditions prevail elsewhere.

Tomorrow...Moderate confidence in flight categories, low 
confidence in timing/location of SHRA.

MVFR ceilings early with some passing -SHRA. Expect improvements to 
VFR by mid-morning (14-16Z). MVFR ceilings redevelop over the south 
coast, Cape, and Islands with another round of SHRA mainly after 18Z.

KBOS Terminal...Moderate confidence in TAF. Bulk of afternoon shower 
activity is north of I-90, but intermittent periods of -SHRA at BOS 
likely through this evening. -TSRA possible between 00-04Z but low 
confidence in whether or not storms occur over the terminal.

KBDL Terminal...Moderate confidence in TAF but low confidence in 
timing of any isolated t-storm risk. 

Outlook /Wednesday Night through Sunday/...

Wednesday Night: MVFR/IFR conditions possible. Breezy. SHRA
likely.

Thursday through Thursday Night: MVFR/IFR conditions possible.
Breezy. Chance SHRA.

Friday: Mainly VFR, with local IFR possible. Breezy. 

Friday Night through Saturday: Breezy. Slight chance RA.
