Spring Weather: Severe thunderstorms, and the SPC

/by

Each year, as the atmospheric pattern begins to undergo a transition and wavelengths begin to change, the threat for strong to severe thunderstorms becomes a focus of the meteorological community in New Jersey, New York and Connecticut. Spring, in fact, marks the beginning of “Severe Weather” season in our area — which generally has been known to begin on May 1st. There have obviously been severe thunderstorms before May 1st, but in general the most consistent potential for organized severe storms begins in May and ends in August or September.

Interestingly enough, severe thunderstorms feature some terminology and atmospheric interactions which can be very confusing not only to interpret as meteorologists, but to understand on the public level. Knowing the basics of how organized thunderstorm events develop, and how forecasters attempt to predict and quantify their potential, will help to make things a little less confusing when severe weather season comes around this year.

Showers, thunderstorms likely through Thursday

/by

These days, Spring’s impacts are fleeting at best. This week won’t be much different, as Spring will make a one day appearance on Thursday and  disappear for several more days thereafter. Nevertheless, the impacts over the next 24 to 48 hours will be noteworthy when it comes to our sensible weather. A warm front approaching the area will be first signaled this afternoon by steady showers, which will continue on and off through the evening. Temperatures will rise into the 40’s as winds turn southerly from the late afternoon into the overnight period.

A low pressure system developing from the Ohio Valley into the Northern Mid Atlantic will aid in the continuation of the aforementioned southerly flow on Thursday. The approaching warm front will continue the chance of showers, with clouds and fog likely in the morning hours. Temperatures, however, will rebound into the 50’s during the day. The warm front will also be home to a tremendous thermal gradient, which will shift northward through New Jersey toward New York City on Thursday.
