Cold With Snow Surrounding Mexico City While Shorts Break Out In New York City Next Week?

Written by on March 5, 2016 in United States of America, Winter 2015/16 with 0 Comments

There’s been a lot of focus on the rain and snow piling into California, heat extending from Plains to East Coast and of course the high potential of a major severe weather outbreak through next week but little has been mentioned about the chill set to drop over Mexico.

The cause of likely 70s reaching all the way to southern New England next week but, in part down to a cold upper low that will descend out of the Bering Sea and eventually cross over northern and central Mexico Tuesday-Wednesday.

As this system digs, so the ridge gets pumped north, northeast with temps widely 15-25F above normal from Front Range to East Coast. That upper trough will drop temperatures big time over a part of the world that would expect to see heat build into the 90s, even low 100s by now. Sure it starts of very warm this week and even as Pacific modified polar air sweeps into northwest Mexico, it stays toasty east of the Sierra Madre Oriental range along the coastal plain.

GFS 500mb height anomalies show this wild, upside down pattern evolve as next week progresses.

GFS prints out over a foot of snow in the Sierra Madre Occidental with potential for a coating to a couple of inches in the mountains surrounding Mexico City.

Just look at the 2m metre anomaly contrast at 00z Wednesday between west, central Mexico and east Texas!

The model has 20s in the Sierra Madre Occidental (Northwest) at the same time it’s in the 90s east of the Sierra Madre Oriental (Northeast).

Some spots within the snow covered Sierra Nevada Occidental could push, even exceed 0F while at the same time remains in the mild 70s along the Bay of Campeche coast.

Looks like a good bet that while it’s snowing in the mountains of northwest Mexico, it could well be in the 70s from DC to Boston Wednesday afternoon.
