Two Places to Enjoy Fresh Summer Snow: Greenland and the Pacific Northwest

Some of us really miss snow in July and it is such a pain to travel to Greenland to experience it.

But don't worry, because of an usually cool weather pattern, you can enjoy snow within a day's car drive, without going to Greenland.

Don't believe me?    Here are National Weather Service precipitation type forecasts from their GFS model.  Blue is snow, rain is green.  First, the forecast for next Sunday morning at 5 AM.   Amply snow in Greenland, but also over the higher elevations in the Northwest.


Six hours later, snow in Idaho!


The origin of this wacky summer weather?   An amazing triple low over western North America and the eastern Pacific, as illustrated by the upper level chart at 11 PM Saturday.   The trifecta of cool.


The long range models have been having a very hard time forecasting the persistent cold trough (low pressure) over the Northwest.  Here is the 4 week forecast centered on July 10th (the date of the above figure).    Yellow or red are above normal heights or pressures.  Didn't have a clue.

The long-term forecasts have consistently missed this persistent western U.S. troughing  (low pressure) and cold.  So I would not put away your sweaters and be prepared for snow at higher elevations in the mountains.

You don't have to go to Greenland to experience snow this week.  Just head to the North Cascades.
