EARLY AFTERNOON SATELLITE IMAGERY SHOWS A TROUGH DIGGING SOUTH INTO
THE FOUR CORNERS REGION AND NORTHERLY FLOW ALOFT THROUGH THE GREAT
BASIN AND MOJAVE DESERT. PEAK WIND GUSTS SO FAR TODAY ARE BETWEEN 30
AND 40 MPH OUT OF THE NORTH FOR MOST LOCATIONS. A FEW STATIONS IN
THE SOUTHERN GREAT BASIN OR OVER HIGH TERRAIN REPORTED GUSTS
APPROACHING 50 MPH. THE LOW IS EXPECTED TO CLOSE OFF TONIGHT THEN
DRIFT SOUTHWEST, BECOMING CENTERED OVER NORTHERN BAJA BY SATURDAY
MORNING. A POTENT JET ALOFT COMBINED WITH A STRONG NORTH TO SOUTH
PRESSURE GRADIENT WILL BRING AN INCREASE IN WINDS TO AREAS SOUTH OF
THE GREAT BASIN, PARTICULARLY DURING THE MORNING AND EARLY
AFTERNOON. PEAK GUSTS SHOULD BE BETWEEN 45 AND 55 MPH IN MOST OF THE
MOJAVE DESERT. HOWEVER, THE FAVORABLE NORTH TO SOUTH FLOW MAY BRING
STRONGER WINDS APPROACHING 60 MPH IN LOCALIZED SECTIONS OF THE
COLORADO RIVER VALLEY. MEANWHILE, THE SOUTHERN GREAT BASIN SHOULD
EXPERIENCE WINDS WEAKER COMPARED TO TODAY'S WINDS. WINDS DECREASE
AREAWIDE ON SUNDAY AS THE LOW TRACKS EVEN FURTHER SOUTH, BUT BREEZY
NORTHERLY WINDS WILL PERSIST IN THE COLORADO RIVER VALLEY. WIND
ADVISORIES REMAIN IN EFFECT AREAWIDE THROUGH SATURDAY EVENING.
THE LOW WILL TRACK EAST ALONG THE INTERNATIONAL BORDER EARLY NEXT
WEEK. MOISTURE ASSOCIATED WITH THE SYSTEM SENDS PWATS TO THE .6 TO
.8 INCH RANGE SOUTH OF INTERSTATE 40 IN ARIZONA AND CALIFORNIA. THIS
BRINGS A 10 TO 20 PERCENT CHANCE OF LIGHT RAIN IN THESE AREAS ON
MONDAY AFTERNOON. BESIDES THAT, DRY CONDITIONS PREVAIL NEXT WEEK.
THE MOST NOTABLE CHANGE WILL BE AN INCREASE IN TEMPERATURES AS HIGH
PRESSURE BUILDS OVER THE EASTERN PACIFIC OCEAN AND SOUTHWESTERN
UNITED STATES. TEMPERATURES INCREASE 15 TO 20 DEGREES BETWEEN
SATURDAY AND THURSDAY AND HIGHS WILL BE 10 TO 15 DEGREES ABOVE
NORMAL BY MIDWEEK. LAS VEGAS HAS A 25 PERCENT PROBABILITY OF
REACHING 90 DEGREES ON THURSDAY. LEVEL 1 (MINOR) HEATRISK SPREADS
ACROSS THE MOJAVE DESERT, A LEVEL OF HEAT THAT WILL AFFECT THOSE WHO
ARE EXTREMELY SENSITIVE TO HEAT AND DO NOT HAVE ADEQUATE COOLING
OR HYDRATION.
