DISCUSSION
AREA OF LOW PRESSURE WILL TRACK THROUGH THE GREAT
BASIN TODAY, PROVIDING NUMEROUS LOWER ELEVATION RAIN SHOWERS ALONG
WITH HIGHER ELEVATION SNOW SHOWERS INTO THIS EVENING. SNOW SHOULD
GENERALLY BE CONFINED TO AREAS ABOVE 7000 FEET ELEVATION. AFTER
SUNSET, THE AREAL EXTENT AND INTENSITY OF PRECIPITATION WILL
QUICKLY WIND DOWN, WITH ALL SHOWER ACTIVITY FORECAST TO END AROUND
MIDNIGHT. A RIDGE OF HIGH PRESSURE WILL THEN BUILD INTO THE AREA
MONDAY, BRINGING A RETURN TO DRY CONDITIONS ALONG WITH WARMING
TEMPERATURES. THE NEXT CHANCE OF SHOWERS ARRIVES LATE TUESDAY,
ALTHOUGH IT APPEARS AT THIS TIME THAT THIS ACTIVITY WILL BE LIGHT
AND ISOLATED. LOOK FOR INCREASED WIND LOADING BY MIDWEEK AS MID
LEVEL FLOW INCREASES.
