AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
200 AM PDT SAT AUG 2 2014

.SYNOPSIS...INCREASING THUNDERSTORM COVERAGE WITH A RISK OF HEAVY
RAIN CAN BE EXPECTED TODAY AND SUNDAY AS DEEPER MOISTURE AND A
POTENT UPPER LEVEL DISTURBANCE MOVE IN FROM THE SOUTH. THIS WILL BE
FOLLOWED BY A DRYING TREND FROM SOUTHWEST TO NORTHEAST EARLY NEXT
WEEK.
&&

.SHORT TERM...THROUGH SUNDAY NIGHT...NOT MUCH CHANGE TO PREVIOUS
THINKING. POTENT UPPER LEVEL DISTURBANCE NEAR THE BAJA SPUR THIS
MORNING WAS STILL TRACKING NORTHWARD AND ADVECTING DEEP SUBTROPICAL
MOISTURE NORTHWARD AROUND ITS EASTERN SEMICIRCLE. DEEP MOISTURE WILL
OVERSPREAD OUR AREA TONIGHT THROUGH SUNDAY NIGHT AND THE DISTURBANCE
WILL SLOWLY TRACK NORTH ACROSS SOUTHERN CALIFORNIA...HELPING TO LIFT
THE MOIST AIRMASS AND PRODUCE LOCALLY HEAVY RAIN. FLASH FLOOD WATCH
LOOKS GOOD AND WILL REMAIN IN PLACE. TEMPERATURES WILL BE
UNSEASONABLY COOL WITH THE CLOUD COVER AND RAINFALL...BUT THE HIGH
MOISTURE CONTENT WILL MAKE IT FEEL QUITE STICKY.

.LONG TERM...MONDAY THROUGH THURSDAY...THE UPPER LOW MOVING UP FROM
THE SOUTH IS FORECAST BY ALL THE MODELS TO BE CENTERED OVER WESTERN
NEVADA MONDAY MORNING WITH ANOTHER SHORTWAVE ROTATING AROUND THE
BASE OF THE LOW INTO THE FORECAST AREA. THIS WILL MEAN A GOOD CHANCE
OF SHOWERS AND THUNDERSTORMS NORTH AND EAST OF THIS SHORTWAVE...IN
OTHER WORDS THE NORTHEAST HALF OF THE FORECAST AREA. I WENT WITH
LIKELY POPS FOR A GOOD PORTION OF LINCOLN AND NORTHERN MOHAVE
COUNTIES. SOME CLEARING MAY BE POSSIBLE MONDAY AFTERNOON IN WESTERN
SAN BERNARDINO COUNTY BEHIND THE SHORTWAVE. PRECIPITATION CHANCES
WILL DECREASE FROM SOUTHWEST TO NORTHEAST MONDAY NIGHT AS THE
SHORTWAVE WORKS INTO UTAH. SOUTHWEST FLOW WILL BE OVER THE AREA
TUESDAY AND WEDNESDAY WITH A PACIFIC TROUGH MOVING INTO CALIFORNIA.
SOME LINGERING MOISTURE WILL COMBINE WITH THIS TROUGH TO KEEP A
SLIGHT CHANCE OF THUNDERSTORMS ACROSS THE NORTHERN PORTION OF THE
FORECAST AREA. MODELS ARE IN GOOD AGREEMENT MOVING THE TROUGH INTO
NEVADA THURSDAY WHICH WILL HELP KEEP A SLIGHT CHANCE OF
THUNDERSTORMS ACROSS THE NORTH EVEN THOUGH DRIER AIR WILL BE MOVING
IN. TEMPERATURES IN THE LONG TERM WILL START OUT PRETTY COOL MONDAY
WITH THE UPPER LOW OVER THE AREA...ALTHOUGH NOT AS COOL AS WE ARE
FORECASTING FOR SUNDAY. THEN TEMPERATURES WILL WARM TO NEAR NORMAL
BY WEDNESDAY AND THURSDAY.
&&

.AVIATION...FOR MCCARRAN...IT WILL BE A DIFFICULT WEEKEND WITH
CHANCES FOR THUNDERSTORMS NEAR THE TERMINAL AND IN ALL APPROACH
CORRIDORS...RESULTING IN PERIODS OF LOW CEILINGS AND NUMEROUS
OUTFLOW BOUNDARIES WHICH WILL BRING SHIFTING WINDS TO THE AIRPORT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THUNDERSTORM CHANCES WILL INCREASE AREAWIDE TODAY AND
SUNDAY...WITH THE MAIN CONCERNS BEING VERY HEAVY RAIN AND ERRATIC
GUSTY WINDS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION MAY BE NEEDED
TODAY AND SUNDAY FOR THUNDERSTORMS WITH VERY HEAVY RAIN AND
POTENTIAL FLASH FLOODING.
