Memorial Day on ice? Canadian cold snap will bring frost to the Northeast and send temperatures plunging into the 20s... but thankfully it's not here to stay 

  • Major cities on the East Coast like Boston, New York, Philadelphia and Washington are likely to escape the coldest blast - with lows in the 50s
  • Coldest air will come Friday as temperatures drop into the 40s in major cities and the 20s and 30s in some inland parts of Pennsylvania, New York and New England
  • Temperatures will rebound for Memorial Day with highs in the 70s and lows in the 60s across the Northeast 

The unofficial start to summer will be marred in parts of the Northeast thanks to some unseasonably cold weather predicted for the upcoming Memorial Day weekend. 

Frosty conditions are expected to descend into the states from Canada on Friday night, with temperatures dropping into the 20s in parts of Pennsylvania, New York, Vermont, New Hampshire and Maine. 

The good news in that Friday is likely to be the coldest day. Temperatures will rebound by Memorial Day into the 60s and 70s across the region. 

The chill spells could ruin not just Memorial Day weekend barbecues but also gardens freshly planted for spring.

The more populated coastal cities of Washington, DC; Baltimore; New York and Boston should escape the surprise frost bite, with temperatures only expected to reach lows in the 40s.  

And temperatures are expected to warm across the region as the weekend progresses. 

The frost is coming unusually late in the year for the Northeast, and experts say that this is likely to be the last freeze until fall for the region from Pennsylvania southward.   

'If it clears out during the last weekend of May, there could be another frost across the interior of New York to northern New England,' Long-range forecaster Paul Pastelok said on Accuweather

'However, that frost threat does not look to be as widespread as this Saturday morning.'

Showers and storms are expected in Texas, Louisiana, the Plains and the inter-Mountain region on Friday

While the Northeast may face cooler-than-usual weather, it will at least escape much of the storms and showers expected in other parts of the country.

On Friday, the chance of scattered showers and thunderstorms are forecast in Louisiana, Texas, the central plains and inter-mountain west, with the possibility of flooding in the southern Plains.

The Pacific Northwest could also receive some showers on Saturday.

On Sunday, the weather will warm up across the nation, with the chance of rain in the western Great Lakes region to the Mississippi Valley and west into the Plains.

But showers and storms could finish out the holiday weekend on Monday in the Northeast, as a warm front moves into the Midwest and Northweast.
