THE STORM IS ALONG THE LOW LEVEL THETA AXIS AND MOISTURE CONVERGENCE AS WELL AS A NARROW BAND OF GREATER INSTABILITY. ONCE STORM EXITS THE CWA ATTENTION WILL THEN TURN TO THE GOOD POSSIBILITY OF LOW CLOUDS AND FOG IN AREAS OVER AND EAST OF THE LARAMIE RANGE. IN THE MOIST SOUTHEAST BOUNDARY LAYER WIND FLOW...THE CLOUDS WILL SLOWLY LIFT ON WEDNESDAY BUT THE DAY WILL END UP BEING MOSTLY CLOUDY AND COOLER THAN IN RECENT DAYS. .AVIATION...00Z TAF ISSUANCE...

SPC HAS ISSUED DISCUSSION STATING WATCH LIKELY. AFTER CONVECTION THIS AFTERNOON AND EVENING MOIST UPSLOPE FLOW SHOULD ALLOW FOR WIDESPREAD STRATUS DEVELOPING OVER MOST AREAS EAST OF THE LARAMIE RANGE.
