Hi everyone – Danielle Noyes here with your Tuesday Insights from the 1DegreeOutside Weather Network. As we dive into mid-July, the dominant weather story is the building heat and humidity, and while not every day features storms, a few “weather-aware” days are ahead.
Wednesday brings the week’s hottest stretch with highs in the 90s across interior New England. Feels-like temperatures will reach 95–100°F for the Merrimack Valley, Southern NH, Central Maine, the Champlain Valley and beyond. Though coastal locations will run a bit cooler thanks to a southwest breeze, even the Cape and Islands will feel tropical with high dew points.
Despite the heat and stickiness, most of Wednesday will be dry. That’s thanks to a mid-level atmospheric “cap” – a warm layer aloft that prevents rising air from triggering storms. It’s like a lid on a shaken soda bottle: pressure’s there, but the lid holds it in. So while we can’t rule out a very isolated pop-up, expect limited storm action on Wednesday.
By Thursday, the cap breaks down as a dip in the upper atmosphere slides east. The result? Scattered thunderstorms, some of which could be strong with localized flooding possible. Timing will matter – we may see one round of downpours in the morning, followed by a second round later in the afternoon if sunshine fuels instability.
As always, use our app’s radar (past + future mode) to track storm timing in your neighborhood. Don’t focus on exact placement, but know that Thursday is a day to be weather aware.
Friday features another hot day in southern New England with highs near 90 again, but cooler, drier air will begin to filter in for far northern and western areas. Humidity will drop behind the front, making for a more comfortable second half of the day.
Saturday looks like a gem, with highs 80–85°, sunshine, and dew points dropping into the 50s – even upper 40s in some inland areas! It’s the pick of the weekend. But by Sunday, humidity climbs again as a warm front lifts back north, bringing the potential for showers and storms to return.
A cluster of thunderstorms over the Florida peninsula is still being monitored by the National Hurricane Center, with a 40% chance of tropical development as it slides westward into the Gulf of Mexico later this week. While it may or may not become a named system, it will bring heavy rain to central Florida and the Gulf Coast states Thursday into Friday.
With recent flash flooding in Connecticut and Western Massachusetts, any slow-moving storms this week bear watching, especially on Thursday. The heat and humidity remain persistent – so stay hydrated, and don’t forget you can track all of it with our free 1DegreeOutside Weather App.
