Near term - through 9pm this evening -
...Other than some high cirrus clouds, skies are sunny this morning, and will remain so through today. Temperatures started out at 57 this morning with a dew point at 43. Strong northwest flow has taken control of the region, ushering in much colder temperatures. 850mb temperatures will be down to 6C to 8C with 800mb dew points dropping as low as -20C, with sunny skies should manage the 70s nonetheless. Low pressure in northern Quebec along with high pressure entering the Great Lakes region will funnel strong winds through New England, with 500mb winds reaching 50kts from the west and 200mb jet stream winds up to 100kts. At this surface, expect northwest winds gusting up to 20mph at times through this afternoon.

Short term - Tonight through Saturday night -
...Clear skies Tonight. 850mb temperatures at 6C, and lows dropping into the mid to upper 40's, with lifted indices around +10 (very stable air). Winds will continue to come strong out of the northwest. Windchill factors may drop to around 40 to 45 for a time tonight.

Low pressure currently entering central Quebec will move east and south, possibly grazing the region with associated cold front on Saturday. There is some potential for isolated thunderstorms on Saturday. An anomalous cold pool at 500mb with mid level lapse rates of 5 to 6 C/km will center to our northwest. This will promote some destabilization of the atmosphere encouraging showers and thunderstorm development, along with possibly some small hail. This is still questionable however, with a lack of moisture at all levels. Included partly cloudy skies with no mention of precipitation in the forecast, however this could change.

High temperatures will reach the mid to upper 70s on Saturday out ahead of the low, with lows up to the upper 40's.

Long term - Sunday through Thursday 7/5 -
...Shower/thunderstorm threat lingers into Sunday, before trough moves east out of New England. High temperatures will fall back to the upper 60's for Sunday on the backside of the storm, with lows in the mid 40's.

Skies clear up again with large high pressure north of the region for Monday and Tuesday. Temperatures will be on a slow rising trend, reaching the mid to upper 70's again by Tuesday.

On Wednesday (Independence Day), a warm front slides through, with warm advection showers and possibly thunderstorms through Thursday. 850mb temperatures will be back up to 15C to 18C. High will reach the mid 70's on Wednesday, and then back into the 80s by the end of next week.
