AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
235 PM PDT MON JUL 24 2006

.SYNOPSIS...TEMPERATURES WILL REMAIN ABOVE NORMAL THROUGH WEDNESDAY
AS THE AREA STAYS UNDER THE INFLUENCE OF STRONG HIGH PRESSURE.
MOISTURE TRAPPED UNDER THE AREA OF HIGH PRESSURE WILL CONTINUE TO
BRING ISOLATED TO SCATTERED LATE DAY THUNDERSTORMS TO THE REGION
THROUGH MID WEEK.
&&

.SHORT TERM...MINIMAL CHANGE IN THE OVERALL PATTERN EXPECTED THROUGH
WEDNESDAY AS STRONG 500MB HIGH REMAINS ROUGHLY OVER SOUTHERN NEVADA
AND SOUTHERN UTAH AND NORTHERN ARIZONA. MOISTURE TRAPPED UNDER THE
HIGH WILL CONTINUE TO LEAD TO ISOLATED TO SCATTERED THUNDERSTORMS
MAINLY IN THE AFTERNOON AND EVENING HOURS. STRONG HIGH WILL ALSO
KEEP TEMPERATURES QUITE HOT. NAM12 IS HINTING AT A POSSIBLE SURGE IN
LOW LEVEL MOISTURE INTO SOUTHERN PORTIONS OF THE FORECAST AREA
WEDNESDAY RESULTING FROM TROPICAL STORM EMELIA MOVING NORTHWEST
FAIRLY CLOSE TO BAJA AND SENDING MOISTURE UP THE GULF OF CALIFORNIA.
GFS SOLUTION NOT CONDUCIVE TO GULF SURGE. NOT MAKING ANY CHANGES TO
FORECAST AT THIS TIME BUT IF A TRUE GULF SURGE DOES DEVELOP WE WILL
PROBABLY HAVE TO LOWER TEMPERATURES AND RAISE POPS FOR WEDNESDAY.

.LONG TERM...
FORECAST TRACK FROM THE NHC FOR TROPICAL STORM EMILIA HAS CHANGED
LITTLE OVERNIGHT...AND STILL EXPECTING EMILIA TO TRACK TO THE
NORTHWEST OFF THE COAST OF BAJA CALIFORNIA THROUGH THE END OF THE
WEEK. ALL SIGNS STILL POINTS TO AN ACTIVE LATTER HALF OF THE WEEK
CWA WIDE AS THE STORMS TRIGGERS A MOISTURE SURGE INTO THE AREA. THE
GFS IS STILL BRINGING WELL OVER 2 INCHES OF PWATS INTO THE SOUTHERN
PORTION OF THE CWA ON FRIDAY AND SATURDAY WITH AT LEAST AN INCH FOR
THE REMAINDER OF THE AREA. IN ADDITION...WITH WINDS UP TO 850MB
MOSTLY UNDER 15 KTS FOR ALL LOCATIONS THE BIGGEST CONCERN WILL BE
FOR FLASH FLOODING DURING THIS EVENT. ALSO OF NOTE IS A 40 TO 50 KT
FLOW AT 250MB ALONG THE NORTHERN HALF OF THE CWA STARTING ON FRIDAY.
THIS SHOULD HELP TRIGGER MORE CONVECTION FURTHER NORTH. THE GFS IS
INDICATING SOME DRYING AS IT ATTEMPTS TO PUSH A TROF INTO THE
PACIFIC NW...BUT THE TREND HAS BEEN WEAKER WITH SUCCESSIVE MODELS
RUNS AND EXPECT THE ABUNDANT MOISTURE WILL REMAIN IN PLACE THROUGH
NEXT WEEK.
&&

.AVIATION...THUNDERSTORMS CONTINUING ACROSS ALL CORRIDORS THIS
AFTERNOON AND EVENING. EXPECT TO SEE GUSTY AND ERRATIC WINDS AROUND
ANY STORMS THAT FORM. TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED
