AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
204 PM PDT WED OCT 1 2014

.SYNOPSIS...LOCALLY GUSTY NORTH WINDS WILL CONTINUE THROUGH THURSDAY
ALONG WITH SLIGHTLY COOLER TEMPERATURES. HIGH PRESSURE BUILDING
OVERHEAD THIS WEEKEND WILL PRODUCE DRY AND WARM WEATHER.
&&

.DISCUSSION...SATELLITE LOOP SHOWED ISOLATED FLAT CUMULUS OVER THE
HIGHER TERRAIN NEAR AND EAST OF LAS VEGAS...WITH CLEAR SKIES FARTHER
WEST. SURFACE OBS SHOWED LOCALLY BREEZY NORTH WINDS BEHIND THE COLD
FRONT WHICH PUSHED THROUGH THE CWA OVERNIGHT INTO THIS MORNING. THE
NORTH WINDS SHOULD BLOW AGAIN TOMORROW...ESPECIALLY DOWN THE
COLORADO RIVER VALLEY. CONSIDERED A LAKE WIND ADVISORY FOR THAT
AREA...BUT HIGH RESOLUTION MODELS SUGGEST THE SURFACE GRADIENT WILL
START TO RELAX BY AFTERNOON...SO SPEEDS MAY STAY JUST BELOW
CRITERIA. NIGHT SHIFT WILL NEED TO TAKE ANOTHER LOOK AT THIS. FOR
FRIDAY AND BEYOND...VERY LITTLE WEATHER OF CONSEQUENCE AS MID LEVEL
RIDGE BUILDS OVERHEAD. TROPICAL DEPRESSION 19 /FORECAST TO BE
TROPICAL STORM SIMON/ WILL PASS NEAR OUR FAVORED MOISTURE SURGE
LOCATION ON FRIDAY...BUT IT APPEARS THAT THE MID LEVEL RIDGE WILL BE
TOO STRONG TO ALLOW ANY EFFECTS TO MAKE IT THIS FAR NORTH. CLEAR TO
PARTLY CLOUDY SKIES...LIGHT WINDS AND ABOVE NORMAL TEMPERATURES
SHOULD BE THE RULE THROUGH THE WEEKEND INTO EARLY NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...NORTH TO NORTHEAST WINDS WILL CONTINUE TO
CAUSE RUNWAY CONFIGURATION ISSUES IN THE AFTERNOONS THROUGH
FRIDAY...BUT SHOULD GET A BIT LIGHTER EACH DAY. NO OTHER
OPERATIONALLY SIGNIFICANT WEATHER IS EXPECTED.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ASIDE FROM BREEZY NORTH WINDS DOWN THE COLORADO RIVER
VALLEY...NO OPERATIONALLY SIGNIFICANT WEATHER IS EXPECTED THROUGH
FRIDAY.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED
THROUGH TUESDAY.
