PRESSURE SYSTEM MOVES THROUGH. SUDDEN STRONG WIND GUSTS WILL
AGAIN BE A CONCERN.

INTO NEXT WEEK.
* BREEZY CONDITIONS AND LOW HUMIDITY WILL LEAD TO ELEVATED FIRE
DANGER FOR THE 4TH OF JULY.
DISCUSSION
THROUGH THE MIDDLE OF NEXT WEEK.
ANOTHER ACTIVE DAY IS IN STORE TODAY AS A LOW PRESSURE SYSTEM
MOVES THROUGH AND INTERACTS WITH A POOL OF MID-LEVEL MOISTURE
ACROSS THE REGION. MOISTURE DEPTH HAS INCREASED A BIT COMPARED TO
TUESDAY AND SURFACE DEWPOINTS HAVE RISEN NOTABLY AS WELL, WHICH
SHOULD WORK TO ENCOURAGE WETTER STORMS. HOWEVER, STRONG WIND GUSTS
WILL REMAIN A POSSIBILITY WITH THE STRONGER STORM CORES ESPECIALLY
IN THE AFTERNOON AND EVENING THANKS TO A DEEPLY MIXED LOWER
ATMOSPHERE. HREF ONCE AGAIN SUGGEST ABOUT A 10% CHANCE OF WIND
GUSTS EXCEEDING 58 MPH ACROSS MUCH OF SOUTHERN NEVADA AND
NORTHWEST ARIZONA WITH 70-90% PROBABILITIES FOR WIND GUSTS OVER
40 MPH. THE INCOMING LOW IS ALSO RESPONSIBLE FOR ONGOING WEAK
CONVECTION EXTENDING FROM THE SOUTHERN GREAT BASIN INTO THE
EASTERN MOJAVE DESERT EARLY THIS MORNING, MAINLY WEST OF LAS
VEGAS. THIS ACTIVITY WILL CONTINUE INTO THE MORNING HOURS AND
SLOWLY DEVELOP EASTWARD, SO A FEW RUMBLES AND GUSTY WINDS WILL BE
POSSIBLE IN THE MORNING HOURS WITHIN THE LAS VEGAS VALLEY BEFORE
MORE ROBUST REDEVELOPMENT OCCURS LATER IN THE DAY.
AS THE LOW MOVES EASTWARD AND WEAKENS TODAY INTO THURSDAY, DRIER
AIR WILL GRADUALLY WORK EAST. THIS WILL RESULT IN PRECIPITATION
CHANCES TAPERING FROM WEST TO EAST WEDNESDAY NIGHT INTO THURSDAY,
THOUGH SOME LINGERING ACTIVITY WILL PERSIST INTO THURSDAY
AFTERNOON ACROSS MOHAVE COUNTY AND PERHAPS LINCOLN AND CLARK
COUNTIES. DRIER AIR WILL SWEEP THROUGH AREA WIDE BY FRIDAY WITH
TEMPERATURES HOVERING NEAR TO SLIGHTLY BELOW NORMAL OVER THE
WEEKEND BEFORE A WARMING TREND BEGINS NEXT WEEK.
THUNDERSTORM ACTIVITY WILL TREND WETTER TODAY WHICH SHOULD LIMIT
THE COVERAGE OF DRY LIGHTNING, THOUGH WESTERN AREAS OF THE GREAT
BASIN AND PARTS OF THE MOJAVE DESERT MAY STILL SEE RELATIVELY
LITTLE RAINFALL WITH THE STORMS. NONETHELESS, SURFACE DEWPOINTS
WILL KEEP MINIMUM RH VALUES ELEVATED AND HELP TO IMPROVE THE FIRE
DANGER SOMEWHAT. HOWEVER, BREEZY SOUTHWESTERLY WINDS ON FRIDAY
WILL RETURN WITH MUCH DRIER AIR PUSHING IN, AND WILL RESULT IN
ELEVATED FIRE DANGER FRIDAY, JUST IN TIME FOR THE 4TH OF JULY.
