.DISCUSSION...A COOL AND DAMP WEATHER PATTERN TODAY WILL BRING
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS THIS EVENING. THE TREND
HAS BEEN FOR PRECIPITATION TO DEVELOP IN NORTHEASTERN WYOMING AND
THEN DISSIPATE AS IT APPROACHES WESTERN PENNINGTON COUNTY. LIGHTNING
ACTIVITY HAS BEEN LOW...BUT ISOLATED LIGHTNING STILL IS POSSIBLE THIS
EVENING. CLOUD BASES HAVE LIFTED...BUT THEY ARE EXPECTED TO LOWER
AGAIN AS THE EVENING PROGRESSES. CURRENT THINKING IS THAT THE CLOUDS
WILL STILL BE ABOVE THE CARVINGS BETWEEN 900 AND 1000 PM MDT. FOG IS
ALSO EXPECTED TO DEVELOP LATER TONIGHT...BUT AGAIN SHOULD HOLD OFF
UNTIL AFTER THE FIREWORKS SHOW. WINDS AT THE TOP OF THE CARVING WILL
RANGE FROM 6 TO 11 MPH FROM THE NORTH-NORTHEAST.
