The Dog Days of Summer?

By Greg Tatro @yourmetgreg July 30, 2014 1:03 pm CDT

If you have been living in the eastern half of the country, you've been enjoying one of the nicest endings to July in quite some time.  Normally many of us would have our air conditioners on full blast and heading out the swimming pool often.  The past couple of weeks a semi-permanent pattern has evolved where a low pressure system is sitting just north of the Great Lakes.  This has kept the Gulf of Mexico closed so the humidity levels have been in the comfortable range.  It has also kept a northwesterly wind flow and this has brought in the cooler air from Canada.  Don't expect much of a change for the rest of this week, and early indications are this could be the prominent feature for August. 

Upper Level Winds

The map is the wind pattern around 30,000 feet above at 7am Wednseday morning.  Observe the large low above the Great Lakes and the wind speeds coming out of the northwest.  This is one of the main reasons it has been comfortable for much of the eastern US.
