DISCUSSION
AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL TRY TO BUILD OVER MT
OVER THE NEXT FEW DAYS. THIS WILL RESULT IN VERY WARM AFTERNOON
TEMPERATURES THROUGH THE WEEK. THERE WILL BE JUST ENOUGH
INSTABILITY FOR A DAILY CHANCE OF A SHOWER/THUNDERSTORM. HOWEVER,
PRECIPITATION WILL BE MINIMAL, WITH MOST SHOWERS ONLY PRODUCING
0.01 OR 0.02 INCHES OF RAINFALL. THE MAIN IMPACT FROM ANY STORM
WILL BE GUSTY WINDS AND LIGHTNING.
