Central PA - Onward Into Summer 2013

Recommended Posts

Now arrives my least favorite part of the year on the east coast...back door season.  Days of low clouds, fog and mist, with the occasional peek of sun mixed in.  I cannot wait for the sun to return in earnest.

There's a bit more clearing than I anticipated.  I wouldn't be surprised to see a few wind reports and sporadic urban/poor drainage flooding spots this evening with the line.

Tornado watch currently for VA and MD up to Mason-Dixon line... makes sense to me based on current severe parameters

I don't envy NWS/SPC on days like today.  You get one spin up tornado and everyone hollers that NWS gave no warning.  Pop a watch, have nothing happen, and everyone decries the NWS.  Lose-lose.

Sun never came out in HBG. Expecting some rain, maybe a little gusty winds, but don't expect much of anything severe.

 

That said, to this Texas kid severe happens baseball-size hailstones are falling and you're scared of trees falling on you. Ha.

70 degrees one day, snowflakes flying the next - in late April. Yay C PA!

I was out in the snow doing a roadside cleanup for Clearwater Conservancy. Not a lot of fun, lol.

 

Got down to 24.2 this am.
