Heat Gone For Now

The latest heat spell has been broken by a cold front but summer has only just begun. The latest shot of heat and humidity produced three consecutive 90 degree days. Wednesday was the hottest with an airport high of 97 and an Inner Harbor high of 99. Wednesday was the hottest day in Baltimore since August 3 last year.

June is almost over and another 90 degree day is not in the cards for the month. This month has recorded seven 90 degree days. In comparison, six 90 degree days are on the books for June of 2006. The similarities with last year end there. This year, June is running about an inch below average on rain and the area looks a little parched because of the heat and spotty nature of the rains that did fall. June of 2006 was very wet due to a late month deluge and the month went down in the record books with a 4.13″ surplus.

The next big summer benchmark is the July Fourth holiday. Temperatures may get close to 90 by then but the biggest concern is any rain that may affect picnics, parades and fireworks. Below are two charts for the GFS computer model for mid week next week.


This long range computer model indicates that a warm front will be in the area on July fourth with a small rain chance. It appears that July fifth would have a higher rain chance when a cold front moves across the area. A lot can happen in the next week to alter this outlook so stay tuned. Enjoy the cooler temperatures and lower humidity levels while they are here.
