KEY MESSAGES
* DRY CONDITIONS, BREEZY AFTERNOONS, AND GRADUALLY WARMING
TEMPERATURES WILL CONTINUE THROUGH THE MIDDLE OF NEXT WEEK.
DISCUSSION
TODAY THROUGH WEDNESDAY.
A BROAD UPPER-LEVEL TROUGH WILL REMAIN ACROSS THE SOUTHWEST THROUGH
THE END OF THE WEEK. BREEZY CONDITIONS CAN BE EXPECTED EACH
AFTERNOON WITH SOUTH TO SOUTHWESTERLY WINDS AROUND 20 MPH COMMON,
ALTHOUGH STRONGER WINDS CAN BE EXPECTED OVER HIGHER TERRAIN. THESE
BREEZES, ALONG WITH THE CONTINUING DRY CONDITIONS, WILL ELEVATE FIRE
DANGER AS WE HEAD INTO THE HOLIDAY WEEKEND. AS INDEPENDENCE DAY
ACTIVITIES INCREASE, INCLUDING COOKING ON CHARCOAL GRILLS AND USING
SAFE-AND-SANE FIREWORKS, PEOPLE ARE ENCOURAGED TO PRACTICE FIRE
SAFETY AND ENSURE ADEQUATE WATER IS READILY AVAILABLE IN CASE A FIRE
STARTS. OVER THE WEEKEND, THE TROUGH WILL FINALLY WEAKEN AND SHIFT
EAST, ALLOWING HIGH PRESSURE TO BUILD OVER THE FOUR CORNERS REGION.
TEMPERATURES WILL GRADUALLY INCREASE THROUGH THE FORECAST PERIOD,
WITH WIDESPREAD MODERATE HEAT RISK (LEVEL 2 OF 4) EXPECTED BY MONDAY
AND CONTINUING THROUGH MIDWEEK NEXT WEEK. LONG-RANGE GUIDANCE ALSO
INDICATES THAT MONSOONAL MOISTURE MAY BEGIN TO MOVE INTO PORTIONS OF
THE FORECAST AREA LATER NEXT WEEK.

WINDS
HAVE GENERALLY FOLLOWED DAILY DIRECTIONAL PATTERNS TODAY; HOWEVER
HAVE BEEN QUITE VARIABLE FROM SSE TO SW AROUND 08-11 KTS WITH GUSTS
TO 17-20 KTS AT TIMES. EXPECT THIS TREND TO CONTINUE THROUGH AROUND
SUNSET, THEN WINDS AND GUSTS DIMINISH QUICKLY THEREAFTER, REMAINING
SOUTHWESTERLY UNDER 8KT OVERNIGHT. EXPECT A SIMILAR PATTERN FOR
TOMORROW WITH VARIABLE WINDS OUT OF THE SE MID MORNING TO EARLY
AFTERNOON, BECOMING SOUTHERLY TO SSW AFTER 18Z WITH HIGHER GUSTS
ABOVE 16 KTS. VFR CONDITIONS WILL PREVAIL, THOUGH SLANTWISE
VISIBILITY REDUCTIONS DUE TO WILDFIRE SMOKE ALONG THE MORMON MESA
CORRIDOR WILL PERSIST.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 00Z FORECAST PACKAGE...WINDS CONTINUE TO FOLLOW
TYPICAL DIRECTIONAL PATTERNS WITH SOME VARIABILITY THROUGH THIS
EVENING. SOUTH TO SW WINDS 10-15KT WITH GUSTS TO 20-25KT PERSIST
THROUGH SUNSET, THEN EXPECT A DIMINISHING TREND OVERNIGHT. AN
EXCEPTION TO THIS WILL BE ACROSS THE WESTERN MOJAVE, INCLUDING KDAG,
WHERE WINDS HAVE BECOME STRONG OUT OF THE WEST WITH SPEEDS AROUND
15KT AND GUSTS PEAKING AROUND 25-30KT. EXPECT A SIMILAR TREND TO
OCCUR FOR FRIDAY AT ALL SITES. OTHERWISE, VFR CONDITIONS WILL
