General:

***SEVERE THUNDERSTORM WATCH UNTIL 10 PM FOR THE SOUTHERNMOST COUNTIES IN VERMONT AND NEW HAMPSHIRE, AND ADJOINING AREAS OF NEW YORK AND MASSACHUSETTS***

This Afternoon: Increasing clouds. Scattered showers and thunderstorms near and north of Route 4, with a rising chance late to the south, and the slight chance of severe storm there. Highs in the upper 60s to lower 70s near the Québec border, mid to upper 70s elsewhere north, and upper 70s to mid 80s in the south. Winds from the west to northwest at 5 to 10 mph.

Brief:

Yesterday was sure not the day for high impact outdoor activities as a thick blanket of haze took over the region due to wildfires out west. You might want to put that big hike or long bike ride on hold until tomorrow as hazy skies prevail through much of the day today. Although a cold front moves over overhead from Canada later today and helps push any lingering smoke to our south through this evening. Today starts dry but the front provides an increasing chance of showers and storms heading to this evening. Some strong to severe thunderstorms likely over southern Vermont and south of the Adirondacks. Today will be the warmest day through the weekend as we settle into a very fall-like weather pattern with afternoon highs in the 70s with low 80s south. Tomorrow offers a great opportunity for more strenuous activities as the smokey haze will not have an impact accompanied by comfortable mid-summer highs in upper 60s to mid 70s. High pressure sinking south from Canada provides a dry day with lots of sunshine. Thursday starts off dry but low pressure passing to our north and south provides an increasing chance of unsettled weather later in the day and overnight. You might want to catch up on some indoor activities on Friday as highs struggle to bust  out of the 60s accompanied by gloomy and wet conditions as showers prevail throughout much of the day.

Winds:

Winds switch to the west to northwest behind a cold front at 10 to 15 mph. Winds tomorrow will generally be light and from the north around 10 mph.
