North American Pattern Displays Upside Down Temp Pattern Next 5-10+ Days!

Written by on August 2, 2013 in United States of America with 0 Comments

There is little change in the models from recent days with the continued hot, dry weather pushing north from the Southwest all the way up into Western Canada while on the other side of the continent, a cooling northwest flow is drawing Canadian air into the Midwest and East.

This weekend into next week looks to see the hot air push further north, potentially driving 90s all the way to the Yukon and Northwest Territories where records are sure to fall. It’s all this hot air gets forced into an area it doesn’t belong in that we see arctic air get tapped, pulled south and this will help form and deepen a cold low north and northwest of Hudson Bay. It’s this feature which drops south over central Canada early next week reinforcing the fall-like chill over Minnesota, the Great Lakes and eventually into the East.

The upper pattern across the continent is ‘wavy’ or meridional with hot air pushing north in the West and cool, dry air dropping south in the East. This setup will keep the fronts dropping into the East, keeping things rather wet, especially over the Central Plains down into the Southeast as we see a collision between cool air driving south and hot, humid air trying to lift north over the next 7 days. Here’s the latest ECMWF total rainfall for the next 168 hrs.

Salt Lake To Threaten Record For Most 100s, Dallas To Top 100 Each Of Next 7 Days!

It would appear Salt Lake City yet again hit 100 today and that makes day 19. The record for most 100s is 22 and that looks in jeopardy as the heat doesn’t look to be leaving the Great Basin over the next 5-7 days. Another place getting hotter is Texas like I’ve mentioned of late. Dallas, you look likely to hit 100 each of the next 7 days at least. Got to at least 103 there this afternoon. Houston is going to hold in the upper 90s to around 100 through the next week.

While it’s hot here and over much of the West, we’ll see a series of fronts drive into the Upper Midwest down towards the Mid-Atlantic region and so there’s NO sign of any real heat getting back up into Minneapolis, Chicago, Detroit, Pittsburgh, DC, Philly, NYC and Boston over the next few weeks. We could see departures of 3-6 below normal over the next 10-15 days in these big cities.
