.WHAT HAS CHANGED...
Showers and storms remain possible this afternoon, diminishing into 
tonight. Some have overachieved and indicated severe features, 
which will continue to be monitored.

&&

.KEY MESSAGES...

- Scattered showers and thunderstorms continue this afternoon
  and will be possible again tomorrow afternoon.

- Dry and pleasant weekend in store for the region.

- Rain, possibly heavy at times, Sunday night into Monday
  morning.

&&

.DISCUSSION...
KEY MESSAGE 1...Spotty showers and thunderstorms continue this 
afternoon and will be possible again tomorrow afternoon.

Spotty showers and thunderstorms have popped up this afternoon in SE 
MA and along the south shore as a surface front pushes through the 
region. Interactions with the sea breeze boundary have also
ramped these up, some turning severe. Showers and storms have 
also popped up just NW of MA, moving SE which may end up 
impacting interior MA. Winds have already shifted more NW in 
areas behind the front. These showers and storms will continue 
to pop up through the rest of the afternoon but will diminish 
heading into tonight. A thunderstorm risk exists for tomorrow as
well, though the risk of them turning severe is low and limited
based on the latest CAMs.

Following the front, drier air will be ushered into the region. This 
will bring PWATs closer to an inch, diminishing further following 
Friday's cold front. HREF guidance has values falling to as low as 
around 0.5". The chance for isolated showers and storms returns in 
the afternoon tomorrow, though  Temperatures will remain seasonable 
with highs in the 80s. Lows tonight will dip into the mid 50s, then 
cooler tomorrow night with a greater possibility for radiational 
cooling. Urban areas will remain slightly warmer.

KEY MESSAGE 2...Dry and pleasant weekend in store for the region.

Sprawling continental high pressure builds S from Canada this 
weekend leading to mild and pleasant days and cool nights. 
Airmass will be quite dry with column-average PWATs falling to 
0.4-0.5 inches. This fall-like airmass will be a welcome break 
from our recent stretch of humidity where dew point temperatures
have been in the upper 60s to low 70s for the past several 
weeks. It will be a mild stretch with the early August sun 
bringing temperatures near or slightly below seasonable levels, 
ranging from the upper 70s to lower 80s. Saturday night into 
Sunday morning, clear skies and light winds provide favorable 
conditions for effective radiational cooling. Lows Saturday 
night range from the low to mid 50s for the majority of the CWA 
and near 60 closer to urban centers. Some guidance even suggests
low in the upper 40s across portions of Northern Massachusetts.

High pressure moves offshore early Sunday, allowing for an 
increasing SWrly return flow. The SW winds bring the return of 60s 
dewpoints though temperatures remain comfortable with highs in the 
upper 70s. Clouds will be on the increase as a shortwave and 
associated frontal system approach from the west later Sunday 
afternoon into the evening. Guidance shows a low level jet 
developing and bringing elevated PWATs over the region after dark 
Sunday. More details about this rainfall threat in the next key 
message. 


KEY MESSAGE 3...Rain, possibly heavy at times, Sunday night into 
Monday morning. 

The next opportunity for rainfall comes during the second half of 
Sunday into Monday. However, there remains uncertainty regarding 
rainfall amounts, as the best forcing is associated with the surface 
low and track variability makes it difficult to pin down where the 
greatest rainfall will occur. This is worth monitoring, as global 
guidance is in agreement that PWATs may exceed 2 inches, indicating 
the potential for heavy rainfall. This is also supported by a 
Marginal Risk (level 1 of 4) for excessive rainfall. Global 
ensembles highlight areas north of I-90 as having the greatest 
likelihood for measurable rainfall, with a 40-60 percent probability 
of at least a half inch of rain between Sunday evening and Monday 
evening. That said, if rainfall becomes more convective, localized 
totals could be higher. One positive is that this system appears 
progressive, with the cold front clearing east of New England on 
Monday. Drier air then advects in from the northwest, leading to 
another dry stretch from the latter half of Monday through Tuesday 
and Wednesday as surface high pressure builds back into the region. 
During this time, temperatures are expected to remain seasonable, 
with highs in the lower to middle 80s and tolerable humidity as dew 
points remain in the lower 60s.
