AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
319 PM PDT FRI JUN 4 2010
.SYNOPSIS...A STRONG AREA OF HIGH PRESSURE BUILDING OVER THE REGION
WILL HOLD THROUGH EARLY NEXT WEEK PROVIDING HOT AND DRY CONDITIONS
WITH TEMPERATURES APPROACHING RECORD LEVELS IN SOME AREAS SUNDAY
AND MONDAY. THIS PATTERN WILL GRADUALLY GIVE WAY TO A BROAD TROUGH
DEVELOPING OVER THE WESTERN STATES AFTER WEDNESDAY LEADING TO A
COOLING TREND WITH INCREASING SOUTHWEST WINDS.
&&
.SHORT TERM...TONIGHT THROUGH MONDAY...THERE IS LITTLE CHANGE IN THE
EXPECTED HOT WEATHER BY THE LATEST MODEL GUIDANCE. THERE CONTINUES
TO BE GOOD AGREEMENT WITH THE OVERALL PATTERN AND ONLY SLIGHT
DIFFERENCES WITH MOS GUIDANCE TEMPERATURES. THERE WAS NO REASON TO
MAKE MANY ADJUSTMENTS TO HIGH TEMPS THROUGH MONDAY. IT STILL APPEARS
THAT MOS GUIDANCE HAS A SLIGHT COOL BIAS SINCE MCCARRAN AIRPORT
ALREADY REACHED 102 DEGREES BY 22Z AND COULD CLIMB ANOTHER DEGREE OR
SO THIS AFTERNOON. THIS LENDS CONFIDENCE TO THE HIGH REACHING AT
LEAST 106 SATURDAY EVEN THOUGH 12Z GUIDANCE KEPT IT AT 105...BUT
THAT IS MAINLY FOR VERIFICATION. THE MAIN STORY IS THAT A PROLONGED
PERIOD OF HOT WEATHER IS ON THE WAY AND THE EXCESSIVE HEAT WARNING
REMAINS IN EFFECT SATURDAY THROUGH MONDAY.
.LONG TERM...SOME CHANGES SHOWING UP IN THE MODELS DURING THE
EXTENDED PERIOD. INITIALLY...HIGH PRESSURE WILL BE THE DOMINATE
FEATURE TUESDAY WITH TEMPERATURES REMAINING SEVERAL DEGREES ABOVE
NORMAL. THE MODELS ARE FORECASTING TO HIGH TO SLIDE A LITTLE FURTHER
EAST TUESDAY AFTERNOON WHICH WOULD LOWER HEIGHTS JUST A BIT. WITH
GUIDANCE STILL SHOWING FORECAST HIGHS AROUND 106 IN LAS
VEGAS...ANOTHER DAY OF EXCESSIVE HEAT WARNINGS MAY BE REQUIRED. BY
WEDNESDAY...BOTH THE GFS AND ECMWF ARE DIGGING AN AREA OF LOW
PRESSURE SOUTHEAST INTO THE PACIFIC NORTHWEST. THIS WILL HELP TO
SUPPRESS THE HIGH A BIT FURTHER SOUTH AND CONTINUE TO LOWER HEIGHTS.
AS THIS TROUGH CONTINUES TO DIG SOUTH...THE FLOW WILL BECOME MORE
SOUTHWEST AND INCREASE. IF THE CURRENT MODELS HOLD THEN WEDNESDAY
AFTERNOON AND MORE LIKELY THURSDAY MOST OF THE AREA WILL SEE BREEZY
CONDITIONS ALONG WITH SLIGHTLY COOLER TEMPERATURES. THE TROUGH AXIS
IS FORECAST TO MOVE ACROSS THE REGION THURSDAY AFTERNOON WHICH WOULD
LOWER TEMPERATURES TO NEAR NORMAL BY THE END OF NEXT WEEK. OTHER
THAN SOME OCCASIONAL CIRRUS AND POTENTIALLY SOME FLAT CU ABOVE
HIGHER MOUNTAINS...SKIES WILL REMAIN GENERALLY CLEAR THROUGH THE
EXTENDED.
.CLIMATE...PARTS OF THE MOJAVE DESERT WILL BE CLOSE TO OR MAY EVEN
GET TO OR ABOVE RECORD HIGHS ON SUNDAY 6/6 AND MONDAY 6/7.
