..MAY SUMMARY
 
 
 
HIGH PRESSURE DOMINATED THE FIRST 5 DAYS OF THE MONTH WITH READINGS  
ACROSS THE REGION GENERALLY 5-10 DEGREES ABOVE NORMAL. A TROUGH OF  
LOW PRESSURE APPROACHING THE COAST BROUGHT THE FIRST REAL HEAT WAVE  
OF THE SEASON TO THE REGION ON MAY 4-5. LAS VEGAS RECORDED IT'S  
FIRST 100 DEGREE TEMPERATURE ON THE 5TH WHILE DEATH VALLEY RECORDED  
111 DEGREES. EVEN THE OWENS VALLEY CRANKED UP THE HEAT WITH BISHOP  
RECORDING 92 DEGREES ON MAY 4. ON MAY 6, THE PATTERN TOOK A DRAMITIC  
SHIFT AS A STRONG COLD FRONT MOVED THROUGH THE REGION. STRONG WINDS  
ALONG WITH THUNDERSTORMS DEVELOPED ALONG THE FRONT WHICH WAS  
FOLLOWED BY MUCH COOLER AIR. LAS VEGAS HAD RECORDED 100 DEGREES ON  
MAY 5, BUT BY MAY 7 THE TEMPERATURE ONLY REACHED 64 DEGREES. THIS  
WAS A DROP OF 36 DEGREES OVER A 2 DAY PERIOD WHICH ENDED UP BEING  
THE BIGGEST 2 DAY TEMPERATURE DROP EVER RECORDED IN MAY. OTHER AREAS  
ALSO EXPERIENCED SIGNIFICANT DROPS. DEATH VALLEY WENT FROM 109 ON  
THE 5TH TO 82 DEGREES ON THE 7TH. KINGMAN WENT FROM 91 DEGREES TO 61  
DEGREES AND MT. CHARLESTON WENT FROM 73 DEGREES ON THE 5TH TO 40  
DEGREES ON THE 7TH. THIS COLD FRONT ALSO PROVIDED SOME PRECIPITATION  
ACROSS THE AREA WITH THE ONLY MEASURABLE RAIN FALL OF THE MONTH  
RECORDED ON THE 6TH AND 7TH. FOR THE NEXT TWO WEEKS FROM THE 7TH  
UNTIL THE 20TH, TEMPERATURES GENERALLY RANGED FROM 5-15 DEGREES  
BELOW NORMAL BEFORE HIGH PRESSURE REISTABILISHED ITSELF AND BROUGHT  
ABOVE NORMAL TEMPERATURES FOR THE REMAINDER OF THE MONTH. OVERALL  
TEMPERATURES FINISHED RIGHT AROUND NORMAL FOR THE MONTH WITH MOST  
AREAS FINISHING WITHIN 1 DEGREE OF NORMAL.  
 
ONE OTHER STRONG COLD FRONT DID MOVE THROUGH THE REGION ON THE 17TH  
AND 18TH WITH MANY AREAS SEEING THE STRONGEST WINDS OF THE MONTH.
