AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
215 PM PDT MON JUL 14 2014

.SYNOPSIS...A MOIST SOUTHEAST FLOW HAS RETURNED TO THE REGION AND
WILL LEAD TO A CHANCE OF THUNDERSTORMS OVER MOST OF THE AREA THROUGH
WEDNESDAY. A DRYING TREND IS EXPECTED FOR THE SECOND HALF OF THE
WEEK.
&&

.SHORT TERM...THE AIR MASS HAS BECOME FAIRLY MOIST OVER THE FORECAST
AREA DUE TO A LARGE SCALE INVERTED TROUGH TO OUR SOUTH AND A
PERSISTENT EAST/SOUTHEAST FLOW. IT IS ESPECIALLY MOIST IN THE SOUTH
WHERE PRECIPITABLE WATER VALUES ARE OVER 1.5 INCHES. MODELS INDICATE
MOIST AND UNSTABLE AIR OVER THE AREA THROUGH TONIGHT AND WITH
OUTFLOW BOUNDARIES AND SMALL SCALE VORTICES AROUND...I KEPT AT LEAST
A SLIGHT CHANCE OF THUNDERSTORMS OVER THE ENTIRE FORECAST AREA
THROUGH TONIGHT...WITH THE HIGHEST POPS THIS EVENING. THE MODELS
SHOW A SHORTWAVE MOVING NORTH INTO THE NORTHERN PART OF THE FORECAST
AREA TUESDAY WITH DRIER AND MORE STABLE AIR STARTING TO PUSH IN
BEHIND IT. SO THE BEST CHANCES FOR THUNDERSTORMS WILL SHIFT TO THE
SOUTHERN GREAT BASIN...TAPERING SOUTH TO NO THUNDERSTORMS FORECAST
ACROSS SOUTHERN SAN BERNARDINO COUNTY. THE MID/UPPER RIDGE IS
FORECAST TO BECOME CENTERED ALONG THE CA/NV STATE LINE WEDNESDAY
WITH CONTINUED DRYING FROM THE SOUTH AND ALSO SOME DRYING PRESSING
IN FROM THE NORTH. SOME MOIST AND UNSTABLE AIR IS FORECAST TO BE IN
TRAPPED IN A BAND FROM ESMERALDA COUNTY TO NORTHERN MOHAVE COUNTY
WEDNESDAY AND WILL SHIFT SLIGHTLY NORTHWARD THURSDAY. NO
THUNDERSTORMS ARE FORECAST FOR LAS VEGAS SOUTHWARD BY THURSDAY.

.LONG TERM /THURSDAY THROUGH MONDAY/...
WEAK RIDGING WILL BE IN PLACE FRIDAY...WITH A CONTINUATION OF THE
DRYING TREND. THUNDERSTORMS WILL BE LIMITED TO THE HIGHER TERRAIN OF
OUR NORTHERN FORECAST AREA. EXPECT AN EVEN LOWER CHANCE ACROSS OUR
NORTHERN HIGHER TERRAIN SATURDAY...WITH MOST LOCATIONS STAYING DRY
AS THE RIDGE OF HIGH PRESSURE SLOWLY SHIFTS TO THE EAST. FORECAST
CONFIDENCE LOWERS SUNDAY THROUGH MONDAY. BOTH THE 12Z GFS AND ECMWF
INDICATE THE RIDGE DROPPING FARTHER SOUTH AND EAST...SETTLING OVER
THE AZ/NM BORDER...BUT THE MODELS DIFFER ON THE OVERALL FLOW ACROSS
OUR REGION. THE GFS PROVIDES MORE SOUTHERLY FLOW ALLOWING FOR
ANOTHER RETURN OF MONSOON MOISTURE ACROSS THE EASTERN HALF OF THE
AREA. HOWEVER...THE ECMWF PROVIDES MORE SOUTHWEST FLOW ALLOWING FOR
DRY CONDITIONS ACROSS MUCH IF NOT THE ENTIRE FORECAST AREA. FOR NOW
WILL SPLIT THE DIFFERENCE AND FOLLOW MORE OF AN ENSEMBLE
APPROACH...KEEPING A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
ACROSS MOHAVE COUNTY EACH AFTERNOON AND EARLY EVENING. AS MENTIONED
IN THE PREVIOUS DISCUSSION...TEMPERATURES WILL BE FAIRLY FLAT
THROUGH THE PERIOD AND WITHIN A COUPLE OF DEGREES OF THEIR SEASONAL
NORMS.
&&

.AVIATION...FOR MCCARRAN...PREVAILING WINDS WILL BE FROM THE
SOUTHEAST TODAY AT 5-10 KTS. ISOLATED THUNDERSTORMS CAN BE EXPECTED
IN ALL APPROACH CORRIDORS DURING THE AFTERNOON AND EVENING. THE MOST
EXTENSIVE THUNDERSTORM DEVELOPMENT IS EXPECTED IN THE PEACH SPRINGS
CORRIDOR. OUTFLOW FROM THUNDERSTORMS COULD CAUSE GUSTY AND ERRATIC
WINDS AT THE TERMINAL THIS AFTERNOON AND EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...AN INCREASINGLY MOIST AND UNSTABLE EAST TO SOUTHEAST
FLOW WILL CONTINUE TODAY AND MONDAY PROVIDING ISOLATED TO SCATTERED
THUNDERSTORMS. AREAS MOST FAVORABLE FOR EXTENSIVE THUNDERSTORM
DEVELOPMENT ARE HIGHER TERRAIN AND NORTHWEST ARIZONA. LOCALIZED
GUSTS AROUND 40 KTS CAN BE EXPECTED NEAR ANY SHOWERS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION MAY BE REQUESTED
TODAY OR TUESDAY. SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT
WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES.
&&

SHORT TERM...HARRISON
LONG TERM...PADDOCK
