KEY MESSAGES

THROUGH THE WEEKEND.
* COOLER CONDITIONS AND GUSTY WINDS WILL RETURN NEXT WEEK WITH
INCREASED CHANCES FOR SHOWER ACTIVITY ACROSS THE SIERRA AND GREAT
BASIN.
DISCUSSION
THROUGH NEXT WEEK.
ONE MORE WEAK SHORTWAVE WILL DROP SOUTH OUT OF THE EASTERN GREAT
BASIN AND INTO NORTHERN ARIZONA TODAY. THIS FEATURE IS WEAK AND
WILL HAVE LITTLE CONSEQUENCE ON OUR REGIONAL WEATHER BESIDES AN
ENHANCEMENT OF NORTHERLY WINDS, ESPECIALLY DOWN THE COLORADO
RIVER VALLEY, THROUGH THE EVENING HOURS. OTHERWISE, TEMPERATURES
WILL CONTINUE TO SLOWLY CLIMB TODAY AND SATURDAY AS A TRANSIENT
HIGH PRESSURE RIDGE BUILDS INTO THE SOUTHWEST. THIS WILL ALLOW
TEMPERATURES TO TOP OUT A FEW DEGREES ABOVE NORMAL TODAY, AND
CLIMB A FEW MORE DEGREES SATURDAY.
BY SUNDAY, A DEEP CUT-OFF LOW OFF THE CALIFORNIA COAST WILL BEGIN
TO APPROACH THE REGION. THIS WILL INDUCE AN INCREASING
SOUTHWESTERLY FLOW ALOFT, AND AFTERNOON WINDS WILL BECOME GUSTY
ESPECIALLY ACROSS OUR WESTERN AND SOUTHERN ZONES. HEIGHTS WILL
BEGIN TO FALL THROUGH THE DAY SUNDAY BUT THE ENHANCED MIXING WILL
MOST LIKELY COMPENSATE, RESULTING IN ONE MORE WARM DAY BEFORE A
MORE SUBSTANCIAL COOLING FOLLOWS FOR MONDAY AND TUESDAY AS THE
LOW CREEPS INLAND. PRECIPITATION CHANCES CONTINUE TO FAVOR THE
SIERRA AND SOUTHERN GREAT BASIN ON MONDAY AND TUESDAY, THOUGH A
FEW INSTABILITY DRIVEN SHOWERS ARE POSSIBLE FURTHER SOUTH TUESDAY
AND WEDNESDAY AS THE COLD CORE ALOFT MOVES THROUGH THE DESERTS.
TEMPERATURES WILL DROP SHARPLY AS THE LOW MOVES THROUGH THE
REGION, WITH AFTERNOON HIGHS TOPPING OUT A FEW DEGREES BELOW
NORMAL. HIGH PRESSURE WILL SLOWLY BUILD BACK INTO THE REGION MID-
LATE WEEK THOUGH THE WEATHER PATTERN LOOKS TO REMAIN ACTIVE AS WE
FINISH THE FIRST WEEK OF MAY.
