.WHAT HAS CHANGED...
No significant changes with this forecast update.
&&
.KEY MESSAGES...
- Significant heat and humidity continues for the rest of this
afternoon and evening. Scattered showers and thunderstorms
possible through the evening. A storm or two may produce
strong to damaging wind gusts.
- Cooler temperatures are forecast for the first half of the
week. Temperatures have the potential to be much cooler as a
soaking rain is becoming more likely in the late Sunday
through Tuesday time frame.
&&
.DISCUSSION...
KEY MESSAGE 1...Significant heat and humidity continues for the
rest of this afternoon and evening. Scattered showers and
thunderstorms possible through the evening. A storm or two may
produce strong to damaging wind gusts.
Hot and humid conditions ongoing across southern New England,
with temperatures and heat indices alike well into the mid-to-
upper 90s. Heat Advisory in effect for northern CT, majority of
MA, and RI until 8 PM EDT this evening.
Elsewhere, convection is continuing across upstate NY and
central/south VT. This activity is trying to "split the gap"
between southern MA/northern CT/RI and northeastern MA. The
northeastern MA solution is winning at the moment, with a
cluster of storms crossing over into parts of Essex County as of
2:45 PM EDT.
High-resolution guidance has been rather ugly in trying to
picture how the rest of this afternoon and evening unfolds.
Overall, ultimately think that this splits up into two different
"events" (such that they are): this afternoon between now and
5-6 PM, and another between 8-11 PM. Firework shows this evening
could be dicey at times, particularly for eastern MA. Showers
and storms move offshore by 2 AM EDT at the latest.
Cold front due before sunrise Sunday morning, where a wind shift
from the NNE will kick in, veering to the ENE throughout the
day. Highs much more reasonable in the low-to-mid 80s.
KEY MESSAGE 2...Cooler temperatures are forecast for the first
half of the week. Temperatures have the potential to be much
cooler as a soaking rain is becoming more likely in the late
Sunday through Tuesday time frame.
High confidence remains that temps will cool down and return to
more seasonable summer readings thru next week. For starters
850 mb temps are forecast to cool to between +12 to +15C. That
will be enough to get temps back into the 80s on its own.
Dewpoints are also forecast to cool down as well, which will
make things feel more comfortable than it has been.
Temps may also be much cooler if we can get substantial cloud
cover and rain into the forecast area. Overnight guidance has
doubled the number of ensemble members with more than 1 inch of
QPF. Now nearly all of the ECMWF ensemble members are in that
camp around BDL, with roughly half of members greater than 1
inch as you move northeast to BOS. However the GEFS has also
moved on board with roughly half of all members at or above 1
inch QPF across southern New England. Deterministic model
guidance is forecasting mid level warm advection to produce an
area of frontogenesis, giving this a little more synoptic
support for rainfall than the more typical scattered summertime
convective pattern to rainfall. NBM PoP looks pretty good at
this range, with categorical across the southwestern forecast
area and likely farther northeast, given the timing uncertainty.
Rain could begin as early as late Sun night and continue thru
Tue. Right now 6 hr FFG across much of the forecast area is at
least 3 inches, so I am not anticipating flooding unless we see
guidance really start to ramp up QPF numbers.
