Written by on July 31, 2014 in United States of America with 0 Comments

Yet another significant record breaking cool morning this July for the Eastern and Southern United States. This is the 3rd big trough, 2nd major record breaker with temps and dew points dropping into the low 50s as the way to central Mississippi, Alabama and Georgia.

Though cool once again this morning, I want to focus on yesterday morning’s lows.

The 59 degree low at Montgomery, AL not only breaks a 125 year record but also ties the all-time July record low. Atlanta’s 59 also broke a record dating back to 1936. While Downtown DC fell to 60, the west suburbs fell into the 40s. Dulles hit a record low of 48 breaking a 1981 record while BWI hit 55.

There have been 3 record lows set this month alone at Dulles Airport which has not occurred in the 1990s or 2000s during a single July.

Morgantown in the north Georgia mountains hit 45 while Mount Mitchell, NC fell to 41 but the price goes to Roam Mountain and Mount LaConte, TN where they plunged to a very impressive 39 and 34 respectively.

With the trough axis centred over the TN Valley and Bermuda high off the EC, we have a flooding rain threat this weekend as a deep tropical flow will ride northward up the coast out of the Caribbean.

Here’s how the next 16 days is looking in the means… GFS shifts trough axis into the west but the question is, how much ridging appears further east as a result?
