Isolated storms today, rough surf in the Northeast this week

When it gets cooler and more unsettled, remember this beautiful stretch of weather! It’s another beauty so far today, and temperatures will continue to climb quite a bit in the Northeast states – well into the 90’s with an increasing southwest flow.

Prolonged heat wave set to begin on Friday

After several weeks of temperatures averaging largely below normal, the hemispheric weather pattern underwent a dramatic shift in early June. Since that time, much of the United States has observed temperatures above normal, with the lone exception being the Northeast states. That will change significantly beginning Friday, as a heat wave begins across a huge area of the Ohio Valley and Northeast – yes, including the urban corridor from Philadelphia to New York City and Boston.

The heat is expected to continue for quite a while. While a heat wave technically was observed in parts of New Jersey a few weeks ago, it will pale in comparison to the temperatures which are approaching starting this weekend – which may very well be the hottest of the year. The heat is expected to persist until the end of next week as a huge ridge builds across the Eastern and Central United States.

A heat wave is coming.

Granted, it hasn’t been easy pinning down the details of this pattern. But forecast model guidance has largely pointed most meteorologists in the right direction when it comes to this upcoming bout of heat. A combination of tropical forcing signals and the wave pattern in the North Pacific Ocean helped tip the hand of the hemispheric evolution, one that signified the development of an anomalous ridge along the East Coast.
