DISCUSSION
THROUGH WEDNESDAY.
BREEZY SOUTHERLY-TO-SOUTWHESTERLY WINDS WILL PICK UP ACROSS
NORTHWESTERN ARIZONA AND SOUTHEASTERN NEVADA THIS AFTERNOON IN
RESPONSE TO A SHORTWAVE ROLLING THROUGH NORTH-CENTRAL NEVADA. THESE
WINDS, COMBINED WITH LOW HUMIDITY, AND DRY FUELS WILL RESULT IN NEAR
CRITICAL FIRE WEATHER CONDITIONS FOR PORTIONS OF MOHAVE COUNTY THIS
AFTERNOON. WHILE THE HUALAPAI MOUNTAINS AND THE HIGHER TERRAIN OF
THE ARIZONA STRIP MAY SEE CONDITIONS BRIEFLY TOUCH RED FLAG
CRITERIA, THE REST OF MOHAVE COUNTY WILL SEE MORE BORDERLINE
CONDITIONS. DUE TO THE SPATIALLY LIMITED NATURE OF THIS THREAT, WE
HAVE OPTED TO NOT ISSUE ANY HEADLINES AT THIS TIME.
DRY CONDITIONS WILL PERSIST THROUGH THE WEEKEND AND INTO EARLY NEXT
WEEK AS WE CONTINUE TO FIND OURSELVES UNDER DRY SOUTHWESTELRY-TO-
WESTERLY FLOW ALOFT. SEASONAL TEMPERATURES WILL ACCOMPANY THESE DRY
CONDITIONS WITH TEMPERATURES FLUCTUATING FROM DAY TO DAY, BUT
REMAINING RIGHT AROUND NORMAL FOR LATE JULY/EARLY AUGUST. HOTTER
THAN NORMAL TEMPERATURES WILL ATTEMPT TO RETURN TO THE REGION DURING
THE SECOND HALF OF NEXT WEEK, AS HIGH PRESSURE TRIES TO PUSH INTO
THE REGION FROM THE EAST. HOWEVER, THERE REMAINS UNCERTAINTY AS TO
JUST HOW HOT WE WILL GET DUE TO INTERENSEMBLE VARIABILITY REGARDING
THE POSITION AND AMPLITUDE OF THE RIDGE.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE
SOUTH
TO SOUTHWEST BREEZES WILL CONTINUE THROUGH THE AFTERNOON WITH
OCCASIONAL GUSTS TO 25 KNOTS POSSIBLE THROUGH SUNSET. SOUTHWEST
WINDS OF LESS THAN 8 KNOTS ARE EXPECTED OVERNIGHT. WINDS WILL
REMAIN LIGHT THROUGH 18Z TOMORROW WITH BRIEF PERIODS OF SOUTHEAST
(150-180) DIRECTIONS POSSIBLE. AFTER 18Z, THE SOUTHWEST WINDS WILL

CONDITIONS UNDER CLEAR SKIES WILL PREVAIL THROUGH TOMORROW, ALONG
WITH AFTERNOON TEMPERATURES EXCEEDING 100F BETWEEN 20Z AND 03Z BOTH

FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...SOUTHERLY BREEZES CAN BE
EXPECTED ACROSS MOST OF THE REGION INTO THIS EVENING. THE EXCEPTION
TO THIS WILL BE THE KDAG AREA, WHERE WINDS WILL REMAIN WESTERLY
THROUGHOUT THE PERIOD. GUSTS IN MOST LOCATIONS OF 15-25 KNOTS CAN
BE EXPECTED, WITH WINDS SUBSIDING AFTER SUNSET. ISOLATED CONVECTION
IS POSSIBLE (20% CHANCE) ALONG THE CENTRAL SIERRA AND WHITE
MOUNTAINS THIS AFTERNOON, WHICH COULD RESULT IN A PERIOD OF GUSTY
AND ERRATIC WINDS ACROSS NORTHERN INYO AND ESMERALDA COUNTIES.
ELSEWHERE, CLEAR SKIES WITH NO POTENTIAL FOR CONVECTIVE IMPACTS.
