.DISCUSSION...
High pressure will bring dry and mild conditions into Tuesday with 
gusty winds at times. A fast moving low pressure system will bring a 
period of rain late Tuesday night into Wednesday morning along with 
cool temperatures. Another system and an associated cold front will 
bring more rain for Thursday.

OUTLOOK...Wednesday through Sunday...

A fast moving low pressure area will push across the region 
Wednesday, bringing an area of rain which should briefly taper off 
Wednesday night. A cold front with bring another round of rain 
Thursday into early Thursday night, which could change to light snow 
before ending across the east slopes of the Berkshires and into N 
central Massachusetts. Some light rain or snow may linger across the 
higher inland terrain on Friday, then high pressure will bring 
mainly dry conditions Friday night into Saturday. The chance for 
rain returns as another system moves across late Saturday night into 
Sunday, with a chance for rain and/or snow at times across the high 
terrain.
