SYNOPSIS
 
 
DRY CONDITIONS TODAY BEFORE CHANCES OF PRECIPITATION RETURN

CONDITIONS, A WARMING TREND IN TEMPERATURES, AND ABUNDANT

NEAR TERM /THROUGH TONIGHT/
 
 
MID AND UPPER LEVEL CLOUDS WILL INCREASE TODAY WITH WEAK  
ISENTROPIC LIFT AHEAD OF LOW PRESSURE APPROACHING FROM THE  
MIDWEST. LOCAL AND UPSTREAM 12Z SOUNDINGS SHOW A DRY LAYER  
EXTENDING UP TO NEAR 700MB (CURRENT RADAR RETURNS TO THE WEST  
ALL THE WAY TO INDIANA WOULD JUST BE VIRGA) SO NO PRECIPITATION  
IS EXPECTED DURING THE DAY.  
 
A SHORTWAVE WILL INCREASE RAIN CHANCES TONIGHT BUT PRECIPITATION  
WILL BE LIGHT AND LARGELY PITTSBURGH AND TO THE SOUTH AS A  
FRONT DROPS DOWN OUT OF THE NORTH.

PRESSURE PASSES SOUTH OF THE FORECAST AREA. PRECIPITATION  
SHOULD MAINLY BE PITTSBURGH AND TO THE SOUTH.  
 
TEMPERATURES WILL BE COOLER ON MONDAY WITH THE BOUNDARY SOUTH OF

LONG TERM /TUESDAY THROUGH SATURDAY/
 
 
DRY CONDITIONS, A WARMING TREND IN TEMPERATURES, AND ABUNDANT  
SUNSHINE CAN BE EXPECTED THROUGH MUCH OF WEEK WITH HIGH PRESSURE  
THE DOMINANT FEATURE. THE TIMING OF THE NEXT LOW PRESSURE SYSTEM  
CONTINUES TO BE A BIT UNCERTAIN BUT ENSEMBLES INDICATE POSSIBLE  
RAIN CHANCES LATER ON FRIDAY.  
 

 
   
AVIATION /14Z SUNDAY THROUGH THURSDAY/
