Hold on! Don't get stressed out yet. I know we've gone from extreme cool and wet to extreme heat and humidity.  But normalcy is on the way.   Out to our west is an approaching cold front.  All the best energy (rain producing cold air aloft) is to the south and north.  We will just see a bunch of clouds go by and cool air move in. 

On the temperature map (and dew point map further down) shows, the last bastion of heat and humidity (high dew point = lots of water) is now squeezed up the east coast ahead of the front.  Almost the entire nation is cooling and drying out right now.  It's very refreshing. 

Just to recap:  Yesterdays High was 95  while the low was 71.  We normally experience 83 as a high and  67 as a low this time of year. After the front passes, that is what you'll enjoy for a number of days. 

The front will pass about 10am to 12pm on Friday with just a chance of rain here and there.  It won't be a day long soaker like many of our storms have been. 

Then beyond that, the front stays to our southeast with ripples of storminess moving up it.  It is hard to nail down exactly when and how much rain we'll get from the ripples (if the front moves a bit further south than expected, then we'll only see clouds pass now and then).  Again, it shouldn't be prolonged periods of rain. 

We'll try to nail down the shower timing tomorrow morning.  Keep cool for a day more.
