Good chance of heavy downpours today

|

Unsettled

 

Another sultry summer day with an increasing chance of heavy downpours today from afternoon thunderstorms.

“A slowly moving frontal system will bring scattered to numerous showers and thunderstorms to the region today and tonight,” the National Weather Service says. “A threat for flash flooding exists with any training thunder storm activity during this time.”

You can track the storms by checking out the radar.

A cold front will approach the area Wednesday into Thursday, bringing more unsettled weather. The front will then move east of the area for the weekend, ushering in high pressure and drier conditions. But until then, we will have to deal with more showers and thunderstorms!

The NWS likes to use that word “training.” What they’re saying is that some of these cells containing thunderstorms are slow moving weather systems. As they hover around an area, the thunderstorms can drop as much as 2 inches an hour. Several of these soaking downpours happened in Connecticut on Tuesday. One cell, centered around the Oxford-Southbury-Newtown area, soaked the area between 3 and 4 p.m. The powerful cell led to a severe thunderstorm warning.

The National Weather Service has a nice page describing the types of thunderstorms and how they form. You can find it here.
