ISSUED AT 545 PM MDT THU JUL 3 2014 OUR EVENING TRIO SHIFT TEAM HAS UPDATED THE GRIDDED FORECASTS FOR THE EVENING HOURS TO INSERT ISOLATED THUNDERSTORMS ALONG AND WEST OF A DOUGLAS TO CHEYENNE LINE...BASED ON OUR CHEYENNE WSR-88D RADAR REFLECTIVITY TRENDS.

SHOULD STILL SEE SOME ISOLATED CONVECTION FIRE INITIALLY AROUND THE MTNS AS THE AFTERNOON PROGRESSES WITH A FEW POSSIBLY STRAYING OVER THE PLAINS INTO THIS EVENING BEFORE DISSIPATING. MORE OF THE SAME EXPECTED FOR FRIDAY THOUGH HIGHER MOISTURE SHOULD ALLOW FOR SOMEWHAT MORE CONVECTIVE ACTIVITY FRIDAY AFTERNOON AND EVENING WITH A WEAK IMPULSE AIDING IT A BIT. AGAIN THIS SHOULD DISSIPATE IN THE EVENING WITH LOSS OF HEATING. TEMPERATURES QUITE WARM FRIDAY WITH MAXS WELL INTO THE 90S OVER LOWER ELEVATIONS.

DECIDED TO CONTINUE WITH OUR TREND OF ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WHICH MATCHES UP WITH PREVIOUS FORECAST AND NEIGHBORS TO OUR EAST AND NORTHEAST.
