Wild Western Ridge, Eastern Trough & Tropical System Next Week!

While temps are currently taking a run at 100° this afternoon from Boston down to DC, this short lived heat spurt will be done by the time the cold front sweeps through later tomorrow afternoon What’s impressing me with this mini heat wave is the rapid rise and eventual fall of these temperatures. Remember it was only 67° degrees two afternoons ago at Dulles Airport in Washington, yesterday the DC area hit 98° and could well top 100° today, by Saturday it’s back in the 80s and by Tuesday if not as early as Monday, highs won’t get out of the 70s. Often, to get near or above 100°, the heat usually takes time to build.

So, while highs return to the 90s up and down the I-95 tomorrow, the cold front slamming this very hot, juicy air mass will trigger some powerful thunderstorms and these will likely cross the cities between 2-5pm tomorrow afternoon, be aware of strong, perhaps locally damaging wind gusts, dangerous lightning, flooding rains and small hail as these storms race through the Big Cities. This will end this hot spell.

For days now, the ECMWF has pointed to a pretty wild western ridge developing as a trough dives into the Lakes and Northeast this weekend and next week. Highs in the very areas nearing or surpassing the 100s today may bounce right back to where they were just two days ago, the 70s, maybe even 60s, certainly for New England but even New York may struggle to get out of the 60s during Tuesday and Wednesday afternoons.

While a substantial push of chilly Canadian arctic air flows into the Northeast and Mid-Atlantic next week, the Great Basin and Rockies are gonna roast yet again with more 100s for Denver with Salt Lake likely to join the century club as well as many western cities. We may see one or two days near 110 from West Texas all the way to Nebraska.

The core of heat right now looks to be focused from the Four Corners to Montana where we may see Glasgow and Miles City see multiple days into the 102-105 range.

ECMWF Shows Tropical Feature Impacting Northeast Gulf Coast Next Week

While the models show a wild pattern next week, it also has a tropical storm developing over the Gulf, taking either a storm or hurricane into the Florida Panhandle mid next week where it re-enters the Atlantic and rides up the East Coast.

This will be something I look at in greater detail tomorrow and through the weekend.

Sorry this is short.. off to bed, back up at 11.50 tonight!
