NATIONAL WEATHER SERVICE CHEYENNE WY  
134 AM MDT SUN MAR 24 2019  
   
DISCUSSION
 
 
ANOTHER WET DAY TODAY AS AN UPPER LEVEL DISTURBANCE MOVES THROUGH  
THE AREA. WE BEGIN TO WARM UP AND DRY OUT MONDAY AND TUESDAY AS A  
RIDGE OF HIGH PRESSURE BUILDS OVER THE AREA. AFTERNOON HUMIDITY  
TUESDAY COULD REACH CRITICAL LEVELS FOR AREAS ALONG AND EAST OF  
THE LARAMIE RANGE. WILL BE QUITE GUSTY TUESDAY AS WELL WITH GUSTS  
TO 35MPH WEST OF THE LARAMIE RANGE. RIGHT NOW...IT DOES NOT LOOK  
LIKE THE WINDS AND LOW HUMIDITY WILL MATCH UP. BUT WILL KEEP A  
CLOSE EYE ON THESE CONDITIONS AS TUESDAY DRAWS CLOSER. ANOTHER LOW  
PRESSURE SYSTEM FOR FRIDAY WILL BRING A CHANCE FOR RAIN AND  
MOUNTAIN SNOW.
