No significant changes.

.KEY MESSAGES...

- Dry and milder Friday, then scattered showers developing
  Friday night.

- Dry this weekend, other than brief scattered showers early Sat 
  morning. Seasonable weekend with highs in the middle 50s to the 
  lower 60s. 

- Summer-like warmth arrives early next week. Highs well into
  the 60s to the lower 70s Mon and potentially 80+ Tue. Duration
  of warmth is uncertain, with backdoor cold front lurking
  nearby midweek. Other than a few brief showers possible at
  times...dry weather dominates.

&&

.DISCUSSION...
KEY MESSAGE 1...Dry and milder Friday, then scattered showers 
developing Friday night.

High pres lingers just off the SNE coast tonight before moving 
further offshore Fri. One more chilly night tonight, although not as 
cold as last night with lows in the 30s. Then we expect a notable 
temp recovery Fri, especially away from the south coast as SW flow 
brings warmer low level temps. Soundings do show a rather shallow 
boundary layer to about 950 mb where temps increase to 12-14C. With 
mostly sunny skies, this will support highs into the upper 60s in 
the interior, but SW flow will keep temps in the 50s near the south 
coast. SW winds will gust to 20-25 mph at times, up to 30 mph on 
Cape Cod. 

Then Fri night decent mid level shortwave passes to the north with a 
modest low level jet developing ahead of an advancing cold front. 
Modest forcing confined with PWATs briefly increasing to around 1" 
ahead of the front will lead to scattered showers moving across the 
region during the late evening and overnight. The front is expected 
to move offshore late Fri night with drying by Sat morning. 

KEY MESSAGE 2...Dry this weekend, other than brief scattered showers 
early Sat morning. Seasonable weekend with highs in the middle 50s 
to the lower 60s. 

A low amplitude northern stream short wave and attending cold front 
move through the region early Sat, 06z to 12z west to east. Rainfall 
amounts will be very light and short-lived (1-3 hrs) in a given 
location. Moisture/PWAT plume is centered over Cape and Islands 12z 
Sat, with rapid drying thereafter as PWATs plunge to 40% of normal 
and surface dew pts fall into the 20s during the afternoon. Hence, 
scattered showers over Cape Cod and Islands at 12z Sat, exit rapidly 
offshore with dry weather overspreading the region after sunrise 
from NW to SE. Modest post frontal CAA with 850 mb temps cooling off 
to -2C to +2C by 18z Sat. Model soundings support mixing beyond 850 
mb, yielding NW winds 15-25 mph. Thus, a cool NW breeze but abundant 
sunshine and deep blyr mixing will help offset with max temps in the 
upper 50s high terrain, to the lower 60s in the coastal plain, 
including Boston- Providence corridor. Given the deep blyr mixing, 
we will lower the surface dew pts given fire weather concerns. 1035 
mb high builds overhead Sat night, yielding ideal radiational 
cooling. Thus, we will adjust mins to reflect the cooler MOS 
guidance here. Other than a chilly Sunday morning, very pleasant 
weather continues Sunday afternoon with rising heights over SNE. 
Surface ridge overhead will promote chilly afternoon seabreezes for 
the coastal plain. However, seasonable temps away from the coast, 
with highs 55-60, but only upper 40s to lower 50s along/near the 
shore. 

KEY MESSAGE 3...Summer-like warmth arrives early next week. Highs 
well into the 60s to the lower 70s Mon and potentially 80+ Tue. 
Duration of warmth is uncertain, with backdoor cold front lurking 
nearby midweek. Other than a few brief showers possible at 
times...dry weather dominates.

High amplitude east coast ridge will provide multiple warm days next 
week. Some uncertainty on duration of warmth, with potential 
backdoor cold front sometime mid to late next week. All ensemble 
systems offer low to moderate probs of 80+ Tue/Wed/Thu next week. 
However, at this time range, low predictability regarding timing 
and amplitude of short wave energy riding over the top of the East 
Coast Ridge and resulting backdoor cold fronts. This large spread in 
timing and amplitude is evident when evaluating individual ensemble 
members, along with AI models and the UKMET. Thus, the overall theme 
remains warm to very warm, along with mainly dry weather next week. 
There could be a brief interruption to the summer-warmth sometime 
around midweek, especially eastern MA given potential for a backdoor 
cold front, but confidence remains low on details. As for precip 
chance, a warm front will cross the region Sun night with the 
potential for a brief round of scattered showers. A few brief 
showers also possible mid week. Otherwise, dry weather
dominates.
