   AREAS AFFECTED...CNTRL IA

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 241630Z - 241700Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...A CONCENTRATION OF STRONG TO SEVERE WIND GUSTS CAPABLE OF
   ISOLD WIND DAMAGE WILL OCCUR COINCIDENT WITH A BOWING LINE SEGMENT
   AS IT MOVES EWD ACROSS CNTRL IA DURING THE NEXT FEW HOURS.

   DISCUSSION...KDMX 0.5 DEG VELOCITY DATA SHOWS A WELL-ESTABLISHED
   REAR INFLOW JET ALONG AND N OF THE I-80 CORRIDOR IN W-CNTRL IA.  THE
   AIRMASS IS GRADUALLY RECOVERING AHEAD OF THE ENEWD MOVING BOWING
   LINE SEGMENT /STORM MOTION 240 DEG AT 48 KT/ WITH TEMPS RISING INTO
   THE MID-UPPER 70S WITHIN A MOIST AND INCREASINGLY UNSTABLE BOUNDARY
   LAYER.  THE SYSTEM MOTION N OF I-80 IS LARGELY ALIGNED WITH THE
   STRONGER DEEP-LAYER FLOW FIELDS...WHICH WILL PROBABLY AID IN
   MOMENTUM TRANSFER TO THE SURFACE IN THE FORM OF STRONG TO SEVERE
   WIND GUSTS.  LATEST THINKING IS A CORRIDOR OF STRONG TO SEVERE WIND
   GUSTS WILL APPROACH THE I-35 CORRIDOR OVER THE NEXT HR WITH AN
   ACCOMPANYING WIND DAMAGE THREAT.
