.KEY MESSAGES...

- Scattered showers tonight, the dry and seasonable this
  weekend. 

- Summer-like warmth much of next week. Monday will be the our 
  transition day to milder weather, with highs well into the 60s
  to the lower 70s. Then potentially 80+ Tue through Fri. 
  However, the arrival and departure of the warmth is uncertain,
  especially in eastern MA with a backdoor cold front lurking 
  nearby. Other than a few brief showers possible at times...dry
  weather dominates.

.DISCUSSION...
KEY MESSAGE 1...Scattered showers tonight, the dry and seasonable 
this weekend.

Northern stream shortwave crosses northern New Eng tonight with
the attendant cold front moving through SNE after midnight. A 
narrow band of PWATs briefly spike to around 1" ahead of the 
front. Modest forcing for ascent combined with this increase in 
moisture will lead to a few showers developing and moving across
the region. However, given the column doesn't fully saturate 
areal coverage will be limited and not all locations will see 
measurable rainfall. 

The front moves off the coast late tonight followed by rapid 
drying Sat as PWATs crash. Expect full sunshine and seasonable 
temps with highs upper 50s to lower 60s, but it will be blustery
in the cold advection pattern with NW gusts to 25-30 mph at 
times. High pres builds over New Eng Sat night so it will be a 
cold night with light winds and clear skies resulting in lows in
the 30s, except upper 20s in the normally colder locations. 
Another dry day Sun as the high slowly moves offshore. Sunshine 
will give way to increasing mid-high clouds in the afternoon in 
the developing warm advection pattern, but any showers ahead of 
the warm front will should hold off until Sun night. Near 
seasonable temps Sun with highs mid-upper 50s.

KEY MESSAGE 2...Summer-like warmth much of next week. Monday 
will be the transition day to milder weather, with highs well 
into the 60s to the lower 70s. Then potentially 80+ Tue through 
Fri. However, the arrival and departure of the warmth is 
uncertain, especially in eastern MA with a backdoor cold front 
lurking nearby. Other than a few brief showers possible at 
times...dry weather dominates.

Main story next week is the subtropical ridge building up the east 
coast, advecting an impressive warm sector airmass into SNE with 
summer-like warmth, potential with highs 80+ multiple days next 
week. The caveat, is that there is a large spread among the model 
guidance, including AI models on the arrival and departure of the 
warm weather. Ensembles, including AI guidance offer probs of 80+ 
temps Tue through Fri, with eastern MA lowest given potential of a 
backdoor front. Given the uncertainty and time range we followed the 
national blend of models (NBM) for highs next week. The warming 
airmass with dew pts eventually climbing into the 60s in the warm 
sector, there will be a low risk of convectively driven isolated 
showers from time to time, as short wave energy traverse north of 
the region. However, most days will feature dry weather.
