   WARM INTO THE UPPER 80S AND LOWER 90S...WHILE SUSTAINED WIND SPEEDS
   OF 20 MPH WILL COMMENCE BY EARLY AFTERNOON IN THIS LOCALIZED AREA.
   AS HIGH PRESSURE BUILDS SWD OVER THE ROCKIES...AN INCREASE IN THE

   ...PORTIONS THE NRN AND CNTRL PLAINS...
   PRESSURE GRADIENT BETWEEN EXITING AREA OF LOW PRESSURE AND HIGH
   PRESSURE SHIFTING EWD WILL ALLOW FOR NWLY WINDS OF NEAR 20 MPH
   ACROSS PORTIONS OF THE NRN AND CNTRL PLAINS. A JET AXIS DIGGING INTO
   THE BACK SIDE OF THE UPPER TROUGH WILL ALSO ALLOW FOR STRONGER WINDS
   TO MIX TO THE SURFACE AT PEAK DAYTIME HEATING. TEMPERATURES ARE
   FORECAST TO RISE INTO THE MID TO UPPER 50S AND LOWER 60S...MAINLY
   ACROSS ERN MT/WY/CO AND WRN SD/NEB WHERE THE BEST JUXTAPOSITION OF
   LOW RH AND STRONG WINDS WILL BE. DESPITE THIS...RHS WILL BE MARGINAL
