  afternoon into Fri along with summerlike humidity as well.

- Mainly dry and seasonable weather follows for the weekend.
  Temps may trend above normal early next week.

.DISCUSSION...

KEY MESSAGE 1...Mostly quiet through Wednesday night. 

Surface high pressure continues to influence southern New England's 
weather as it builds in from the Ohio valley this afternoon. Even 
so, a lingering mid level trough/cold pool aloft is leading to a 
smattering of diurnal cumulus and hit-and-miss showers over 
western/central areas. With sunset these showers will 
dissipate and cloudcover quickly recede. Tonight expect clear skies 
with light winds and patchy fog in the interior where dewpoint 
depressions may be near 0. Wednesday is dry and sunny with mid level 
ridging building in. As this happens, the low/mid level flow backs 
to the SW 850mb temps bump up from ~11C to 12-13C pushing high 
temperatures a few degrees warmer on Wednesday, into the upper 
70s/low 80s with cooler temps along the coast. 

KEY MESSAGE 2...A round or two of scattered showers & thunderstorms 
possible Thu afternoon into Fri along with summerlike humidity as well.

The model guidance is in fairly good agreement in an approaching 
shortwave trough/cold front late in the work week. Out ahead of this 
disturbance...S-SW flow will result in the return of low level 
moisture and summerlike humidity. While specific timing remains 
uncertain...the potential exists for a round or two of scattered 
showers and thunderstorms sometime Thu afternoon/night into Fri. The 
CSU machine learning probabilities also indicate a low risk for 
severe weather/heavy rainfall. That is basically climatology for an 
approaching shortwave this time of year. But the question remains 
does the forcing/instability lineup favorably for that potential to 
be realized along with various mesoscale processes. It is just too 
early to determine that at this time. Nonetheless...certainly 
something to watch over the next day or two.

KEY MESSAGE 3...Mainly dry and seasonable weather follows for the 
weekend. Temps may trend above normal early next week. 

High pressure builds in behind the departing shortwave/cold front 
for the upcoming weekend. The result will be mainly dry and 
seasonable weather Sat into Sun. Ensembles indicating upper level 
flow may become more westerly early next week allowing for temps to 
trend above normal.
