Tuesday’s Insights: There’s A Lot of Meteorology To Cover Today!

From the epic overnight rain in Vermont to the likelihood of more storms ahead, continued humidity, and a tropical system that may develop as it nears the Eastern Seaboard, there’s a lot of meteorology to cover in today’s 1°Outside Insights!  Matt Noyes explains the thought process behind the forecast, and includes a look at our 14-day dewpoint prediction, as well.

Rainfall and Current Conditions

The rain has been epic across parts of the Northeast Kingdom of Vermont, with radar estimates and actual reports showing over 8 inches of rain just north of Saint Johnsbury. This resulted in multiple road and state highway washouts. Grafton County, New Hampshire, was also hit hard. While many of us didn’t see that much rain, those areas directly under the center of atmospheric energy coupled with mountainous terrain experienced significant downpours.

Weather Overview

As we move forward, we have another storm center approaching. A warm front will bring a surge of humidity and warmth over the next couple of days. Today, there is a chance for severe storms across Northern New England, with isolated severe storms possibly producing damaging winds. The dew point is cranked up, making torrential rain a bigger concern as we head into Wednesday.

Dew Point and Humidity

The high humidity and dew points will stick with us up to the upcoming weekend, impacting events like the Pan-Mass Challenge. Expect some variations and bigger swings in humidity as we move into next week.

Forecast Details

  • Today: Chance for isolated severe storms in Northern New England.
  • Wednesday: Showers in the morning will become more numerous by midday. Greatest concern is Wednesday afternoon into the evening, with potential for localized flash flooding and perhaps a few rotating storms.
  • Thursday: A cold front comes through but stalls over us, leading to widely scattered storms in Southern New England.
  • Friday: The front returns with moisture and humidity, leading to a chance of isolated showers and thunderstorms, especially in the afternoon.
  • Saturday: A shower in the morning, followed by a break, then more showers and thunderstorms in the afternoon are likely.  Plenty of warmth and humidity.

Tropics Update

There’s a 60% chance of development from the National Hurricane Center. The current disturbance is battling Saharan dust, which is dry air. As it moves away from the dust, it enters more favorable conditions for tropical development. By the weekend, we’ll need to keep an eye on its potential impact on the Eastern Seaboard. Here in New England, the setup suggests a lower likelihood of direct impact due to strong westerlies aloft by Monday, but the Bahamas to Florida to the Carolinas want to watch this one closely.
