   ...SYNOPSIS...
   UPPER LOW VCNTY SWRN ORE SHOWS NO SIGN OF MOVING TODAY OR TONIGHT
   WITH SEVERAL SHORTWAVE TROUGHS EXPECTED TO ROTATE THROUGH THE GREAT
   BASIN AND ROCKY MTS.  SUBTROPICAL FLOW WILL REMAIN SUPPRESSED
   ACROSS NRN MX INTO SRN TX.  AT THE SURFACE...COLD FRONT WILL MOVE
   EWD THROUGH NEW ENGLAND TODAY...WHILE TAIL END OF THE FRONT REMAINS
   QUASISTATIONARY FROM THE LOWER OH VLY NWWD INTO THE CNTRL ROCKIES. 
   THE FRONT WILL BE THE FOCUS OF PERIODIC TSTM EPISODES.
   
   ...CNTRL HIGH PLAINS INTO THE MID MS VLY...
   OVERNIGHT MCS CONTINUES TO WANE AS LLJ VEERS AND WEAKENS THIS
   MORNING ACROSS KS.  OUTFLOW BOUNDARY EMANATING FROM THE LARGE TSTM
   CLUSTER HAS REINFORCED THE FRONT SITUATED ACROSS NRN KS.  AS CLOUD
   CANOPY ERODES THIS MORNING AND LOW LEVEL FLOW TURNS UPSLOPE...
   HEATING SHOULD ALLOW THE FRONT/OUTFLOW BOUNDARY TO RETURN NWD INTO
   SRN NEB/NRN KS BY MID AFTERNOON.  NEAR 60F DEW POINTS BENEATH STEEP
   MIDLEVEL LAPSE RATES AND MAGNITUDE OF HEATING WILL CONTRIBUTE TO
   VERY UNSTABLE CONDITIONS BY AFTERNOON WITH MLCAPES OF 1500-2500
   J/KG FROM SERN WY INTO SRN NEB/NRN KS.  
   
   WEAKLY DIFFLUENT UPPER FLOW REGIME AND INCREASED CONVERGENCE ALONG
   THE WARM FRONT SHOULD AID IN TSTM INITIATION OVER SCNTRL NEB BY MID
   AFTERNOON...WITH OTHER TSTMS POSSIBLE ALONG THE SERN WY MTS. 
   SUPERCELLS WILL BE POSSIBLE AS SFC-6KM SHEAR WILL BE 35-40 KTS AND
   VERY LARGE HAIL IS POSSIBLE ALONG WITH DAMAGING WINDS.  LOW LEVEL
   SELY FLOW INVOF OF THE FRONT WILL BE SOMEWHAT WEAK...BUT IF TSTMS
   CAN MOVE ALONG THE BOUNDARIES...ISOLD TORNADOES WILL BE POSSIBLE. 
   
   ACCELERATION OF THE SLY LLJ AFTER SUNSET SUGGESTS THAT ONE OR MORE
   MCS/S WILL MOVE EWD ACROSS SRN NEB/SWRN IA/NRN KS/NRN MO OVERNIGHT
   WITH UPSTREAM ACTIVITY POSSIBLE AFFECTING THE CNTRL HIGH PLAINS. 
   THE HAIL AND WIND THREAT WILL CONTINUE INTO EARLY WEDNESDAY
   MORNING.
   
   ...WRN KS SWD INTO SWRN TX...
   AS MIDLEVEL RIDGE AMPLIFIES DOWNSTREAM FROM UPPER TROUGH...850-700
   MB TEMPERATURES WILL CORRESPONDINGLY RISE A COUPLE OF DEGREES OVER
   MONDAY/S TEMPERATURES.  THUS...CINH WILL BE A LITTLE STRONGER ALONG
   THE DRY LINE FROM WRN KS INTO SWRN TX THIS AFTERNOON.  THERE WILL
   STILL BE THE THREAT OF ISOLD TSTMS DEVELOPING BY MID-LATE
   AFTERNOON...ESPECIALLY FROM THE SRN PLAINS OF W TX SWD INTO THE
   SWRN TX MOUNTAINS.  VERTICAL SHEAR WILL BE RATHER WEAK...LESS THAN
   25 KTS...ACROSS THE SWRN KS-TX CAPROCK CORRIDOR...BUT A LITTLE
   STRONGER ACROSS SWRN TX BENEATH SUBTROPICAL JET.  THUS...THE
   STRONGER...MORE ORGANIZED TSTMS /POSSIBLE SUPERCELLS/ WILL BE
   ACROSS SWRN TX IF PARCELS CAN BREACH THE CAP.  LARGE HAIL WILL BE
   THE PRIMARY SEVERE THREAT ALL ALONG THE DRYLINE.  
   
   ...CNTRL/SRN FL...
   TSTMS ARE EXPECTED TO DEVELOP ALONG SEABREEZE COLLISIONS/RESIDUAL
   FRONT BY AFTERNOON ACROSS CNTRL/SRN FL.  WHILE MIDLEVEL THERMAL
   RIDGE SEEMS TO BE EVOLVING OVER THE ERN GULF OF MX...AT LEAST THE
   ERN PART OF THE FL PENINSULA SHOULD MAINTAIN SUFFICIENTLY STEEP
   MIDLEVEL LAPSE RATES TO SUPPORT ISOLD STRONGER TSTMS WITH HAIL AND
   DAMAGING WINDS.
   
   ...GREAT BASIN...
   7H-5H BAROCLINIC ZONE WILL SHARPEN ACROSS THE NWRN UT DESERTS THIS
   MORNING...AND MOVE CLOSER TO INSTABILITY AXIS ACROSS CNTRL/NRN UT
   BY AFTERNOON.  A FEW TSTMS ARE EXPECTED THAT MAY PRODUCE ISOLD
   LARGE HAIL OR DAMAGING WIND GUSTS.
