Northeast Severe Threat, Thursday, Frost This Weekend?

Written by on May 22, 2013 in United States of America with 0 Comments

Quick post with some thoughts on the next couple of days as well as a look into next week.

Severe threat Wednesday will be focused over the Tennessee, Ohio Valley extending up into the eastern Great Lakes, interior Northeast, i.e western, central PA, western NY etc. By Thursday that severe threat shifts to the Big Cities from DC up through Philly, NYC but looks to stay slightly west of Boston, perhaps eyeing Albany.

The heat is on too with low to mid-80s ahead of Thursday’s front from DC to NYC but look out during the PM hours for that front sliding in from the west, those storms may well get frisky. Damaging winds, hail and flooding rains are the biggest threat with these I think.

Once that front pushes through and heads out into the Atlantic, a cool NW flow will bring down temperatures and humidity this weekend, making for cool nights and very comfortable days.

Interestingly, the Canadian high which drops down may support some unusual chill with a frost over the interior Northeast. This looks possible Saturday, Sunday night’s.

As for next week, it starts off cool over the Northeast but look out, heat will build over the Southwest and with a system pushing into the West Coast, that building heat shifts into the Plains states. May see upper 90s and 100s show up mid next week over Oklahoma, Kansas into Nebraska. Eventually that heat shifts through the Ohio Valley into the Northeast.

Severe weather is likely to erupt again next week over the Plains!

We may see the first 90s for Philly, maybe NYC late next weekend into the weekend!
