NATIONAL WEATHER SERVICE LAS VEGAS NV
330 AM PDT SAT MAY 10 2014
CORRECTION TO PREVIOUS VERSION
.SYNOPSIS...WINDS WILL BEGIN TO INCREASE THIS AFTERNOON AS A STORM
SYSTEM APPROACHES THE AREA. STRONG WESTERLY WINDS WINDS WILL DEVELOP
ACROSS PORTIONS OF THE MOJAVE DESERT AHEAD OF A COLD FRONT AND
STRONG NORTHERLY WINDS WILL DEVELOP BEHIND THE FRONT TONIGHT AND
SUNDAY WITH MUCH COOLER TEMPERATURES. SHOWERS WILL BE LIMITED TO
LINCOLN AND NORTHERN MOHAVE COUNTIES. DRY CONDITIONS AND A WARMING
TREND CAN BE EXPECTED MUCH OF NEXT WEEK AS HIGH PRESSURE BUILDS IN
FROM THE WEST.
&&
.SHORT TERM...
THROUGH SUNDAY NIGHT...WINDS ARE EXPECTED TO INCREASE SIGNIFICANTLY
THIS AFTERNOON OVER MUCH OF SAN BERNARDINO COUNTY AHEAD OF A STRONG
COLD FRONT THAT WILL MOVE THROUGH THE REGION THIS AFTERNOON AND
EVENING. GRADIENTS WILL TIGHTEN DURING THE AFTERNOON AND WINDS
ACROSS SAN BERNARDINO ARE EXPECTED TO REACH HIGH WIND WARNING
CRITERIA BY LATE AFTERNOON AND EVENING. SURFACE PRESSURE GRADIENTS
AND THERMAL GRADIENTS ARE ALSO EXPECTED TO TIGHTEN SIGNIFICANTLY
BEHIND THE COLD FRONT WHICH WILL MOVE THROUGH THE NORTHWEST CWA LATE
THIS AFTERNOON. WINDS ARE LIKELY TO EXCEED WARNING CRITERIA AND HAVE
UPGRADED ALL HIGH WIND WATCHES TO WARNINGS. TEMPERATURES ARE
EXPECTED TO BE RATHER WARM AHEAD OF THE FRONT WHICH WILL HELP IT
ACCELERATE AS IT MOVES SOUTH AND IS EXPECTED TO REACH SOUTHERN
NEVADA EARLY THIS EVENING. PAST STUDIES HAVE SHOWN THAT WINDS OVER
55 MPH ARE POSSIBLE IN THIS SITUATION. STRONG NORTHERLY WINDS ARE
ALSO LIKELY TO OCCUR DOWN THE COLORADO RIVER VALLEY OVERNIGHT AND
SUNDAY AND HAVE INCLUDED THOSE AREAS IN THE WARNING. NOT MUCH
MOISTURE ASSOCIATED WITH THIS SYSTEM AND PRECIPITATION LOOKS TO BE
CONFINED TO LINCOLN AND NORTHERN MOHAVE COUNTIES. THERE WILL BE SOME
SIGNIFICANT COOLING BEHIND THE FRONT WITH TEMPERATURES ON SUNDAY
AROUND 10-15 DEGREES COOLER. STRONG NORTHWEST WINDS WILL PERSIST
THROUGH SUNDAY BEFORE DECREASING SUNDAY NIGHT.
.LONG TERM...
MONDAY THROUGH SATURDAY...RIDGING OFF THE WEST COAST EXPANDS
EASTWARD INTO THE MOJAVE DESERT AND SOUTHERN GREAT BASIN THROUGH THE
WEEK. A WARMING TREND WILL ENSUE AS TEMPERATURES RISE FROM 5-7
DEGREES BELOW NORMAL MONDAY TO 10 DEGREES ABOVE NORMAL BY FRIDAY.
MODELS HAVE HAVE BEEN VERY CONSISTENT WITH THIS FEATURE AND
CONFIDENCE REMAINS HIGH REGARDING INCREASING TEMPERATURES BUT
MODERATE WITH ACTUAL NUMBERS. LOOKING AT MOS GUIDANCE, TEMPS SHOULD
BE SLIGHTLY ABOVE NORMAL WEDNESDAY BUT THEN INCREASE AN ADDITIONAL
4-6 DEGREES FOR THURSDAY. FRIDAY HAS CONSISTENTLY LOOKED LIKE THE
WARMEST DAY OF THE WEEK WITH TEMPERATURES APPROACHING THE CENTURY
MARK. THIS IS STILL WELL OFF THE RECORD FOR THE DATE AND SINCE WE
HAVE ALREADY SEEN SIMILAR TEMPERATURES EARLIER IN THE MONTH, NO HEAT
RELATED HAZARD PRODUCTS ARE ANTICIPATED. LOW PRESSURE OFF/NEAR THE
PACIFIC NORTHWEST COAST SATURDAY COULD GENERATE GUSTY CONDITIONS
OVER PORTIONS OF THE AREA WITH TEMPERATURES SIMILAR OR JUST SLIGHTLY
COOLER THAN FRIDAY.
.AVIATION...FOR MCCARRAN...
SOUTHWEST WINDS 10-15 KTS EXPECTED TO PERSIST THROUGH MID
MORNING...BUT WILL INCREASE TO AROUND 15-25 KTS THIS AFTERNOON.
WINDS ARE EXPECTED TO INCREASE MORE JUST AHEAD OF A COLD FRONT THAT
WILL MOVE THROUGH THE REGION BETWEEN 02Z-04Z THIS EVENING. WINDS
BEHIND THE FRONT ARE EXPECTED TO BE STRONG WITH NORTHWEST WINDS
25-35 KTS AND GUSTS OVER 40 KTS AND POTENTIALLY UP TO 50 KTS. CLOUDS
WILL BE OPERATIONALLY INSIGNIFICANT AS VARIABLE HIGH LEVEL CLOUDS
WITH BASES ABOVE 20 KFT MOVE OVER THE AREA.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...STRONG WEST WINDS WILL PERSIST ACROSS PORTIONS OF THE
MOJAVE DESERT THIS MORNING...BUT INCREASE TO AROUND 20-30 KTS AND
GUSTS OVER 50 KTS THIS AFTERNOON. A COLD FRONT WILL MOVE THROUGH THE
REGION LATE THIS AFTERNOON AND EVENING WITH SOUTHWEST WINDS UP TO 40
KTS AHEAD OF THE FRONT AND NORTHWEST WINDS WITH GUSTS UP TO 50 KTS
BEHIND THE FRONT. SHOWERS ARE POSSIBLE TONIGHT AND SUNDAY ACROSS
LINCOLN AND NORTHERN MOHAVE COUNTIES AND BLOWING DUST WILL BE A
CONCERN OVER THE REMAINDER OF THE AREA.

.FIRE WEATHER...STRONG WINDS AND VERY DRY CONDITIONS ARE EXPECTED

THE COLORADO RIVER. A RED FLAG WARNING HAS BEEN ISSUED VALID FROM 10
