Pacific Northwest enjoys sunny 80s, 90s, Northeast suffers gloomy 50s, 60s, late week Nor’easter?

While the Southwest sweats in 105-110F and 80s and 90s extending all the way up to the interior Pacific Northwest with records likely to fall, it’s very different on the other side of the continent with an unusually cool trough with plenty of thick cloud trapped beneath covering the Northeast.

Check out the contrast between Northwest and Northeast both at 2 metres above the ground and up at 850mb (5,000ft) this afternoon. 20 above vs 20 below.

It’s more like April rather than June across throughout the Northeast this afternoon.

Boston could threaten record low maximums/minimums over the next 24 hours.

Further south and it’s somewhat warmer for DC and surrounding area TODAY but coolest conditions shall be felt tomorrow with a struggle to get much above 70.

Nor’easters are coastal lows which impact the Northeast US. Their typically strongest during the winter months and become less deep and less impactful during the summer months when there’s less contrast in air and sea temperature.

Coastal Nor’easters can affect the Northeast from DC to Maine during any month of the year and the models are all over a potentially deep low running up and close to the New England coast late this week bringing coastal gales and several inches of rain.

When folks within this region turn minds to heat, humidity and thunderstorms, Thursday-Friday could be unusually cool, wet and windy and feeling more autumnal than June-like.

Note the NAM early Friday has an unusually deep 985mb low near the north shore of Cape Cod. If correct, this would be a real howler for the Cape and surrounding coastline with power outages likely.

Certainly a weather chart you’d not expect in early June but more November.
