..NO THUNDERSTORM AREAS FORECAST  
 
   
..SUMMARY  
 
THUNDERSTORMS ARE NOT EXPECTED ON THURSDAY.  
   
..SYNOPSIS  
 
IN THE WAKE OF A STRONG SHORTWAVE TROUGH MOVING INTO THE CANADIAN  
MARITIMES, A MID/UPPER CYCLONE IS FORECAST TO PROGRESS FROM THE  
ONTARIO/QUEBEC BORDER VICINITY EASTWARD THROUGH QUEBEC ON THURSDAY.  
STRONG MID-LEVEL FLOW THROUGHOUT THE BASE OF THIS CYCLONE IS  
EXPECTED TO EXTEND FROM THE NORTHERN/CENTRAL PLAINS THROUGH THE  
NORTHEAST. EVEN WITH THESE STRONG DYNAMICS, EXTENSIVE SURFACE  
RIDGING IS EXPECTED FROM THE NORTHERN PLAINS INTO MUCH OF THE  
EASTERN CONUS, PROMOTING DRY AND STABLE CONDITIONS. CONSEQUENTLY, NO  
THUNDERSTORMS ARE ANTICIPATED.  
 
FARTHER WEST, A LOW-AMPLITUDE SHORTWAVE TROUGH IS EXPECTED TO  
PROGRESS ACROSS THE GREAT BASIN INTO THE FOUR CORNERS REGION WHILE  
ENHANCED MID-LEVEL WESTERLY FLOW ASSOCIATED WITH IT SPREADS FROM  
SOUTHERN CA ACROSS THE SOUTHWEST. SOME MODIFIED MOISTURE RETURN IS  
ANTICIPATED ACROSS SOUTH TX LATE THURSDAY NIGHT/EARLY FRIDAY  
MORNING, BUT THIS WILL REMAIN WELL DOWNSTREAM OF THE SHORTWAVE  
TROUGH. AS SUCH, THE LACK OF MOISTURE/BUOYANCY AHEAD OF THIS  
SHORTWAVE WILL PRECLUDE THUNDERSTORM DEVELOPMENT.
