THROUGH SUNDAY.
A RIDGE OF HIGH PRESSURE WILL BUILD INTO THE REGION DURING THE WEEK
AS THE PESKY LOW PRESSURE SYSTEM FINALLY EXITS TO THE EAST. CLEAR
SKIES WITH MOUNTAIN TOP SNOW ARE SHOWN IN CURRENT SATELLITE IMAGERY,
WITH A WARMING AND DRYING TREND TAKING OVER FOR THE NEXT SEVERAL
DAYS. A FEW SHORTWAVE TROUGHS WILL ADVECT THROUGH THE DESERT
SOUTHWEST OVER THE WEEK, BRINGING ONLY A SLIGHT REDUCTION IN
TEMPERATURES AND BREEZY NORTHERLY WINDS OVER THE COLORADO RIVER
VALLEY. ELEVATED WINDS WILL CREATE HAZARDOUS CONDITIONS OVER AREA
LAKES, WITH INCREASED WAVE HEIGHTS, ESPECIALLY ON TUESDAY AND
WEDNESDAY. TEMPERATURES WILL REMAIN NEAR SEASONAL NORMALS THROUGH
THE WEEK.
ENSEMBLE SOLUTIONS ARE CONTINUING TO ALIGN ON ANOTHER TROUGH
BRINGING COOLER TEMPERATURES WITH A CHANCE OF PRECIPITATION NEXT
WEEKEND. THERE REMAINS SIGNIFICANT VARIATION ON TIMING AND EXTENT OF
IMPACTS BASED ON THE TRACK OF THE TROUGH. FORECAST OUTCOMES RANGE
FROM ANOTHER POTENTIALLY SIGNIFICANT PRECIPITATION EVENT FOR THE
REGION TO ONLY A SLIGHT INCREASE IN WINDS AND DECREASE IN TEMPERATURES.
THEREFORE, FORECAST CONFIDENCE IN EITHER OF THESE SCENARIOS IS
LOW; HOWEVER, THERE IS INCREASING AGREEMENT IN SOME SORT OF
PATTERN SHIFT.
