   ...NO THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   The risk for thunderstorms appears negligible across the U.S Tuesday   
   through Tuesday night.   
      
   ...Discussion...   
   While a blocking high to the north of the Aleutians may undergo at   
   least some short-lived suppression, models indicate that a   
   downstream high may become a bit more prominent across the southern   
   mid- to subtropical latitudes of the eastern Pacific during this   
   period.  As this occurs, a belt of strong anticyclonic flow is   
   likely to be maintained across much of the eastern mid-latitude   
   Pacific through the northern U.S. intermountain region and Rockies.   
      
   One of a number of short wave perturbations progressing through this   
   jet is forecast to emerge and contribute to amplifying mid-level   
   troughing as it digs across the northern Great Plains through Upper   
   Midwest, accompanied by a rapidly migrating surface cyclone into the   
   upper Great Lakes by late Tuesday night.  It appears that this will   
   be trailed by a gradually consolidating and increasingly significant   
   surface cold intrusion.   
      
   A notable preceding surface front may remain a focus for   
   thunderstorm development near and south-southeast of the Florida   
   Straits Tuesday into Tuesday night.  The trailing flank of this   
   front is forecast to weaken across the southwestern Gulf Basin, and   
   some Gulf boundary-layer modification may commence to the north.   
   However, this is likely to remain rather modest, and an initial   
   low-level offshore flow across the Gulf Coast, veering to an   
   increasing westerly component by Tuesday night, will tend to inhibit   
   inland moistening.
