AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
430 AM PDT TUE JUN 15 2010

.SYNOPSIS...A LOW PRESSURE SYSTEM OVER THE PACIFIC NORTHWEST WILL
MOVE INTO NORTHERN NEVADA BY WEDNESDAY. THIS SYSTEM WILL BRING
BREEZY SOUTHWEST WINDS THIS AFTERNOON AND EVEN STRONGER WINDS AREA
WIDE WEDNESDAY. TEMPERATURES WILL DECREASE TO BELOW NORMAL WEDNESDAY
AND SLOWLY INCREASE TO NEAR NORMAL BY WEEKS END AS A BROAD TROUGH OF
LOW PRESSURE HOLDS OVER THE WEST.
&&

.SHORT TERM...TODAY THROUGH THURSDAY...THE MAIN FEATURE TO WATCH IS
THE UPPER LOW CENTERED NEAR VANCOUVER THIS MORNING. THE ECMWF AND
AND NAM SOLUTIONS CONTINUE TO DRIVE THIS SYSTEM DOWN INTO NORTHERN
NEVADA WEDNESDAY WHILE THE GFS KEEPS IT OVER OREGON AND IDAHO. THE
FORECAST TRENDS REMAIN BASED ON THE DEEPER SOLUTIONS WHICH WOULD
LEAD TO STRONGER WINDS ACROSS MUCH OF THE FORECAST AREA TONIGHT
THROUGH WEDNESDAY. THE FIRST AREA TO BE IMPACTED WILL BE THE
SOUTHERN SIERRA AND OWENS VALLEY WITH THE POTENTIAL FOR DOWNSLOPE
WINDS INCREASING THIS EVENING AND HOLDING THROUGH WEDNESDAY
AFTERNOON AS THE TROUGH AXIS SWINGS ACROSS. 00Z HIGH RESOLUTION
MODEL RUNS SHOW THE POTENTIAL FOR HIGH WINDS BEGINNING THIS EVENING
THEN PERSISTING UNTIL MID TO LATE WEDNESDAY AFTERNOON.
HOWEVER...CROSS-SECTIONS KEEP STRONG WINDS GENERALLY ON THE MID TO
UPPER SLOPES FOR NOW AND NOT SURE HOW GOOD OF A CRITICAL LAYER MAY
SET UP NEAR THE RIDGETOPS. WILL KEEP THE WATCH UP FOR NOW AND SEE IF
DETAILS CAN BE PINNED DOWN BETTER WITH ADDITIONAL/NEWER DATA.
WIDESPREAD GUSTY SOUTHWEST WINDS SHOULD DEVELOP OVER MOST OF THE
FORECAST AREA BY 18Z WEDNESDAY AND CONTINUE THROUGH WEDNESDAY
EVENING AS THE UPPER LOW SKIRTS ACROSS NORTHERN NEVADA INTO NORTHERN
UTAH BY WEDNESDAY EVENING. THE ASSOCIATED SURFACE FRONT PUSHES DOWN
THROUGH SOUTHERN NEVADA BY LATE WEDNESDAY EVENING WITH NORTH WINDS
CONTINUING THROUGH EARLY THURSDAY MORNING. ANOTHER UPPER LOW QUICKLY
DROPS INTO THE PACIFIC NORTHWEST BEHIND THE EXITING SYSTEM AND WILL
MANAGE TO PRODUCE SOUTH WINDS BY THURSDAY AFTERNOON BUT SPEEDS
SHOULD GENERALLY BE LESS THAN 20 MPH.

.LONG TERM...LITTLE CHANGE NEEDED THIS EVENING TO THE EXTENDED
FORECAST AS MODELS SHOW GOOD CONTINUITY WITH PREVIOUS RUNS. LOW
PRESSURE ACROSS THE PACIFIC NORTHWEST AND HIGH PRESSURE TO THE
SOUTHEAST WILL RESULT IN DRY SOUTHWESTERLY FLOW ACROSS THE CWA.
GUSTY SOUTHWEST WINDS COULD DEVELOP EACH  AFTERNOON AND POSSIBLY GET
SOME ENHANCEMENT FROM WEAK DISTURBANCES PASSING NORTH OF THE REGION
AT TIMES. TEMPERATURES SHOULD BE RIGHT AROUND NORMAL LEVELS WITH NO
LARGE FLUCTUATIONS EXPECTED EITHER WAY. &&

.AVIATION...FOR MCCARRAN...SOUTHWESTERLY SURFACE FLOW WILL INCREASE
TODAY AND WEDNESDAY AS A STORM APPROACHES AND MOVES THROUGH THE
NORTHERN GREAT BASIN. WIND SPEEDS IN GENERAL ARE EXPECTED TO BE IN
THE 10 TO 20 MPH RANGE TODAY BUT INCREASE TO 20 TO 30 MPH WITH
HIGHER GUSTS WEDNESDAY AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTHWESTERLY SURFACE WINDS WILL INCREASE TODAY AND
WEDNESDAY AS A STORM APPROACHES AND MOVES THROUGH THE NORTHERN GREAT
BASIN. WIND SPEEDS IN GENERAL ARE EXPECTED TO BE IN THE 10 TO 20 MPH
RANGE TODAY WITH THE STRONGEST GUSTS OVER THE WESTERN FORECAST AREA.
WIDESPREAD GUSTY CONDITIONS ARE ANTICIPATED FOR WEDNESDAY AFTERNOON.
&&

.FIRE WEATHER...WINDS WILL INCREASE THIS AFTERNOON IN ADVANCE OF AN
UNSEASONABLE STRONG LOW PRESSURE SYSTEM. WINDS WILL BE BREEZY THIS
AFTERNOON AND DIE DOWN AFTER SUNSET IN MOST AREAS...EXCEPT FOR THE
SIERRA AND OWENS VALLEY WHERE VERY STRONG DOWNSLOPE WINDS ARE
FAVORED THIS EVENING THROUGH WEDNESDAY. WIDESPREAD STRONG SOUTHWEST
WINDS AND SINGLE DIGIT RELATIVE HUMIDITIES WILL COMBINE TO CREATE
CRITICAL CONDITIONS LATE WEDNESDAY MORNING THROUGH WEDNESDAY EVENING
ACROSS MUCH OF SOUTHEAST CALIFORNIA...SOUTHERN NEVADA AND NORTHWEST
ARIZONA. WIDESPREAD GUSTS OVER 35 MPH WILL LIKELY OCCUR FOR SEVERAL
HOURS.
