   SATELLITE AND UPPER AIR ANALYSIS INDICATES STRONG BLOCKING PATTERN
   ACROSS THE U.S.  THIS IS DOMINATED BY MID/UPPER LEVEL LOW OVER THE
   ERN GREAT LAKES WITH ITS ASSOCIATED CIRCULATION COVERING THE
   CENTRAL AND ERN PARTS OF THE U.S.  ALSO...HI AMPLITUDE RIDGE
   EXTENDS FROM CA NEWD INTO THE WRN DAKOTAS LEAVING MODERATE FLOW
   OVER THE NWRN U.S.  SURFACE RIDGING OVER SWRN ONTARIO NOW EXTENDS
   SWD ACROSS THE UPPER MS VALLEY INTO THE CENTRAL PLAINS.  THIS HAS
   LEFT A QUASISTATIONARY BOUNDARY FROM ERN NC WSWWD ACROSS SRN MS
   INTO THE S PLAINS OF TX AND ALONG THE FRONT RANGE OF THE SRN AND
   CENTRAL ROCKIES INTO ERN MT.
   
   ...CENTRAL AND ERN MT INTO THE FRONT RANGE OF CO...
   
   SURFACE/LOW LEVEL MOISTURE HAS BEEN PUSHED UP AGAINST THE ROCKIES
   THIS MORNING AS THE SURFACE RIDGE HAS EXTENDED SWD INTO THE PLAINS.
   
   WATER VAPOR SATELLITE IMAGERY SHOWS CYCLONIC CIRCULATION ASSOCIATED
   WITH GREAT LAKES LOW COMBINED WITH MODERATE MID LEVEL FLOW OVER THE
   NWRN U.S. HAS DELINEATED A DEFORMATION ZONE OVER ERN MT SWD THROUGH
   ERN WY.  00Z VERSION OF NSSL MM5 SHOWED THIS AREA TO BE THE BEST
   FOR DEVELOPMENT OF CONVECTION...AND THE MORNING 40KM ETA ALSO
   INDICATED THIS AS A SECONDARY LOW DEVELOPS OVER S CENTRAL MT
   UNDERNEATH UPPER LEVEL JET EXIT REGION.  REMAINING AIR MASS ACROSS
   THIS AREA IS MOIST WITH SURFACE DEW POINTS IN THE LOW/MID 50S...AND
   WITH DAYTIME HEATING IS POTENTIALLY UNSTABLE WITH SBCAPE FORECAST
   TO BE AROUND 1500 J/KG.  EXPECT THUNDERSTORMS TO REDEVELOP THIS
   AFTERNOON WITH DAYTIME HEATING AS LOW DEVELOPS ENHANCING UVVS. 
   ISOLATED SEVERE THUNDERSTORMS COULD PRODUCE DAMAGING WINDS AND HAIL
   INTO EARLY TONIGHT.  AREA EXTENDS SWD INTO PARTS OF CO WHERE THERE
   IS STILL SOME UPSLOPE FLOW ENHANCING CONVERGENCE ACROSS THE FRONT
   RANGE.
   
   ...ERN NC AND SC...
   
   MODELS INDICATE THAT FRONTAL BOUNDARY ACROSS AREA HAS LIMITED THE
   ERN AREAS TO ANY SEVERE WEATHER THREAT THIS AFTERNOON AND THIS
   EVENING.  LOW LEVEL FLOW IS WLY ACROSS THE AREA AS WEAK MID/UPPER
   LEVEL SHORTWAVE TROUGH/ASSOCIATED VORTICITY MAX MOVES EWD ACROSS
   NRN AL/NRN GA...JUST AHEAD OF COMPARATIVELY STRONGER FEATURE MOVING
   SWD/SEWD OVER THE LOWER MO VALLEY.  SCATTERED THUNDERSTORMS ARE
   EXPECTED IN MOIST AIR MASS WITH DEW POINTS IN THE MID 60S AND WHERE
   MODELS SHOW SBCAPE TO APPROACH 2000 J/KG LATER TODAY.  SOME WET
   MICROBURST POTENTIAL EXISTS WITH THE STORMS AS WELL AS SOME HAIL.
