Meteorological summer began on June first and since that time we have had very little need for any air conditioning. June was a cool month with an average temperature two degrees below normal. In addition there were only three nights all month when the temperature failed to fall below 60 degrees at the Portland Jetport. So far July has followed this script but there appears to be a bump in the road as warmer and more humid air is expected to arrive here on Tuesday. This should result in more clouds and a few afternoon showers or thunderstorms. It will also cause dew points to shoot up well into the 60s which will make for a muggy night Tuesday night.

Fortunately the humid air will not be here for long. A cold front is going to move through our region Wednesday morning ushering in drier air and by Wednesday night we'll have much more comfortable air in place. There could be a few showers with the frontal passage and then the rest of the week is looking dry right now.
