MORNING UPDATE HAS BEEN SENT REMOVING MORNING FOG. ONE LONE
THUNDERSTORM MOVED QUICKLY ACROSS WASHINGTON AND WESTMORELAND COUNTIES
THIS MORNING, BUT THAT HAS NOW HAS MOVED INTO THE MOUNTAIN COUNTIES TO
OUR EAST AS IT WEAKENS. EXPECT MORE ACTIVITY TO FIRE THIS AFTERNOON AS
DEWPOINTS CLIMB INTO THE UPPER 60S AND SUNSHINE WILL HELP DESTABILIZE
THE ATMOSPHERE. TRIGGER TEMPERATURE CALCULATED AT 26C/79F TODAY.

MAIN CLUSTER OF CONVECTION CURRENTLY MOVING THROUGH JANESVILLE-BELOIT
WISCONSIN WITH ANOTHER AREA NEAR DES MOINES IOWA.  EXTRAPOLATION WOULD
PUT THAT AREA IN OUR NECK OF THE WOODS LATE THIS EVENING.  ACARS DATA

280/40KTS OVER OHIO. AS SUCH, I EXPECT PULSE-TYPE STORMS TO DEVELOP
OVER THE AREA THIS AFTERNOON AND MOVE PRETTY MUCH DUE EAST.

AFTERNOON PACKAGE CONCERNS WILL BE ON CONVECTION FOR MONDAY EVENING AS
IMPRESSIVE HELICITY/FRONTOGENIC FORCING/AND SOUPY DEWPOINTS WILL BE
