Select One:

1.  Thanks Obama

2.  Global Warming

3.  Hot air from Republican Convention

When I have a Head Advisory, it's usually in effect as soon as I crawl out of bed. 

Come to think of it, that could be noon.

I've been looking forward to the thunderstorms, but they never end up happening!

We need rain ... everything is so dry!  But I don't want major storms though.  Just have to wait and see and watch Max's reports.  I actually came on here this morning to check on the storm.  We will get something though because I am going out to water the gardens. Storms always happen after I water LOL

Wanted to see if you were paying attention

Always glad to pay attention to you and your posts. (Once my daily fog clears.)

Tornado warnings northwest of Scranton

Why is it that summer storms are the worst ?  Is it the heat?

Dog hiding in the bathroom.  There must be a storm coming.

Getting kind of dark and windy out there.

Yes - sort of.    It's actually related to the amount of energy that's stored in the humid air that we have this time of year.  It takes a tremendous amount of heating to turn liquid water into water vapor (latent heat of vaporization).   Then, when we get the right atmospheric conditions,  the moist surface air gets lifted (convection) and that water vapor turns into big, puffy cumulus clouds. (You'll often notice that it looks really "nice" out earlier in the day of big thunderstorms. )  If there is no inversion in the atmosphere, those clouds just keep growing, letting all of that energy go at once.   

The concept is "Convective Available Potential Energy" -  you'll sometimes here forecasters talk of high CAPE values.   It's measured in Joules/Kilogram of air.   Today there are values in excess of 3,000 J/Kg in the area.    That's in the range of severe storms, which we are seeing.

Short answer is, yes, heat contributes to instability

GAH! Just got the emergency alert on my phone. So much for that little nap on the couch.

Thanks Max !  I wish the storm would cool us off a bit though !  Really dark here now and thundering.

Haven't heard a crack of thunder that loud in a LONG time...

Oh it is!    Allentown airport cooled off by 15 degrees in 1 hour just now.   Morristown and Newark both went down by 10 degrees.    Think about all of that water pouring down from clouds 20,000 or 30,000 feet high.  It entrains a lot of cold air from aloft that will very quickly cool down the surface.   I was showing 82 on the car thermometer vs. 95 when I left Liberty Corner 30 minutes ago.
