Weather: Big heat and humidity come back (9/4/2018)

Heat Advisory September 5 2018

Tuesday night, it stays relatively comfortable with lows in the upper 50s & low to mid 60s. Wednesday, heat & humidity come roaring back. Expect mostly sunny skies and highs well into the 80s & 90s. Whether you make it to the 90s or not, humidity will make it feel like you did. A heat advisory is in effect for the Champlain Valley, St. Lawrence Valley & Upper Valley. The heat index there will be around 95-100°.

Wednesday night, a cold front arrives and brings showers and thunderstorms with it. We’ll have to pay close attention to storms entering the North Country before midnight. The severe threat is low but some of the strongest cores may put down damaging wind, heavy rain, and frequent lightning. Storms will weaken after midnight but continue through the morning drive. Temperatures to start the day will be around 70°, that’s still muggy. Showers and storms will continue to move south through the early to mid-afternoon, some of them in central/southern VT & NH may be strong. Meanwhile, temperatures will max out in the upper 70s & low 80s during the late morning or early afternoon. By the time we’re eating dinner, temperatures will have fallen into the 60s & low 70s. It’ll feel like a totally different season!

Friday, Saturday, and Sunday will feel amazing by comparison. Highs will struggle to get to 70° under mostly sunny skies each day. Overnight lows will be crisp and chilly! Most will fall into the upper 40s & low 50s, but I wouldn’t be shocked if parts of the NEK and Adirondacks go back into the 30s Friday night & Saturday night. 

The leftover moisture from now Tropical Storm Gordon will get here by early next week. This may end up being a beneficial slug of rain. Exact details are still being worked out but signs point to a cloudy, cool and wet start to our next work week. Stay tuned.

Have a great week!
