ISSUED AT 811 PM MST TUE NOV 5 2013 WINDS GUSTS IN AREAS ALONG AND WEST OF THE LARAMIE RANGE RANGE HAVE BEEN BETWEEN 40 AND 55 MPH SO FAR THIS EVENING. THE LOW LEVEL HEIGHT DIFFERENCES ACROSS THE CWA HAVE BEEN SLOWLY INCREASING AND LOOK TO PEAK FROM NOW THROUGH 14Z. WILL CONTINUE TO MONITOR FOR THE NEED OF A HIGH WIND WARNING...BUT AT THIS TIME BELIEVE THAT WINDS WILL STAY BELOW HIGH WIND CRITERIA FOR THE VAST MAJORITY OF THE TIME. TEMPERATURES WERE ALREADY STEADY OR SLOWLY RISING AT 03Z IN RESPONSE TO THE TIGHTENING SURFACE PRESSURE GRADIENT.
