.DISCUSSION...
KEY MESSAGE...Prolonged spell of dry weather is expected through 
the workweek, to go along with a warming trend to temperatures. 

Southern New England remains entrenched in a cool cyclonic flow 
pattern, leading to mostly sunny to partly cloudy skies, modest 
northwest breezes and near to slightly cooler than seasonable 
temperatures with chilly nighttime temperatures. Expect more of the 
same through Monday night, although with a bit less breeziness 
Monday. Still enough of a NW gradient tonight to offer lows around 
the freezing mark (close to daytime dewpoints), but light/calm winds 
Monday night could point to Monday night being rather cold with 
forecast lows in the mid 20s outlying valleys to lower to mid 30s. 

For Tuesday and really into most of the workweek, strong high 
pressure at surface and rising 500 mb heights aloft govern Southern 
New England, with modest westerly winds. Expect clear skies and a 
lengthy stretch of dry weather ahead, one with strong diurnal 
temperature ranges - increasingly mild days but cool nights. 
Temperatures could trend quite a bit above normal as we move into 
Thursday and Friday, as 925 mb temps rise to around +10 to +12C, and 
it wouldn't shock if we see temps reach into the mid to perhaps even 
upper 60s. Our next best chance for precipitation may not 
materialize until the weekend as the ridge tries to break down, 
but even that is far from set in stone.
