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.
AVIATION...FOR HARRY REID...FOR THE 12Z FORECAST PACKAGE
LIGHT
AND VARIABLE WINDS WILL CONTINUE THROUGH MID-MORNING WHEN WINDS
WILL PICK UP AND SWING AROUND TO THE NORTHEAST. 8 TO 12 KNOT
NORTHEASTERLY WINDS WITH 15 TO 20 KNOT GUSTS WILL CONTINUE THROUGH
THE AFTERNOON AND INTO THE EVENING HOURS WHEN WINDS WILL BECOME
LIGHTER AND SWING AROUND TO A MORE WESTERLY DIRECTION IN A TYPICAL
DIURNAL FASHION. THESE LIGHT WESTERLY WINS WILL CONTINUE THROUGH
SATURDAY MORNING WHEN WINDS WILL BECOME LIGHT AND VARIABLE. VFR
CONDITIONS WILL PREVAIL WITH FEW TO SCT CLOUDS AT OR ABOVE 12KFT.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 12Z FORECAST PACKAGE...LIGHT WINDS WILL GIVE
WAY TO BREEZY NORTH-NORTHEAST WINDS ACROSS MOST OF THE REGION
LATER THIS MORNING. STRONGEST WINDS IN THE LOWER COLORADO RIVER
VALLEY WHERE GUSTS 20-30 KNOTS ARE LIKELY (80%). WINDS WILL WEAKEN
AROUND SUNSET. THE EXCEPTION TO THIS WILL BE IN THE OWENS VALLEY,
INCLUDING KBIH, WHERE WINDS WILL REMAIN RELATIVELY LIGHT AND WILL
FOLLOW TYPICAL, DAILY DIRECTIONAL TRENDS. VFR CONDITIONS WILL
PERSIST THROUGH THE TAF PERIOD WITH CLOUD BASES REMAINING AT OR
ABOVE 10KFT.
