DISCUSSION
THROUGH EARLY NEXT WEEK.
MOSTLY CLEAR SKIES AND WARM TEMPERATURES DOMINATE THE REGION THIS
AFTERNOON WITH FORECAST HIGHS EXPECTED TO TOP OUR SEVERAL DEGREES
ABOVE NORMAL. WARM TEMPERATURES WILL CONTINUE THROUGH THURSDAY
BEFORE HEIGHTS BEGIN TO DECLINE SHARPLY FRIDAY INTO THE WEEKEND.
THE HOTTEST CONDITIONS ARE EXPECTED TUESDAY BEFORE A MODEST
MOISTURE INCREASE ARRIVES WEDNESDAY AND THURSDAY WHICH WILL SHAVE
A COUPLE DEGREES OFF THE TEMPERATURE EXPECTATIONS.
SPEAKING OF MOISTURE, A WEAK SHORTWAVE TROUGH OFF THE COAST OF
THE BAJA WILL LIFT NORTH ON TUESDAY AND PULL A PLUME OF DEEPER
MID-LEVEL MOISTURE INTO THE MOJAVE DESERT BY TUESDAY AFTERNOON
AND EVENING. LATEST CONVECTIVE ALLOWING GUIDANCE FAVORS SOME WEAK
SHOWER ACTIVITY ACROSS THE WESTERN MOJAVE DESERT NEAR THE MORONGO
BASIN TUESDAY AFTERNOON, AND THAT ACTIVITY DEVELOPS NORTHWARD INTO
SOUTHERN NEVADA BY WEDNESDAY MORNING. INSTABILITY WILL BE QUITE
LIMITED SO NOT EXPECTING ANY OF THE ACTIVITY TO BE ESPECIALLY
ROBUST, BUT DRY LOW LEVELS WILL FAVOR LOCALLY GUSTY WINDS AND SOME
DRY LIGHTNING RISK IF CLOUD DEVELOPMENT BECOMES DEEP ENOUGH TO
SUPPORT LIGHTNING ACTIVITY. MOISTURE WILL BEGIN TO SHIFT EAST BY
LATE WEDNESDAY WITH PRECIPITATION CHANCES BY THURSDAY LIMITED TO
FAR EASTERN MOHAVE COUNTY AND LINCOLN COUNTY.
THEREAFTER, A LARGE A DEEP TROUGH WILL DEVELOP ACROSS THE PACIFIC
NORTHWEST AND DROP SOUTHWARD THROUGH THE WEEKEND. THIS PATTERN
SHIFT WILL RESULT IN DRY AND GUSTY CONDITIONS RETURNING TO MUCH OF
THE REGION, AND GIVEN THE DRY VEGETATION ACROSS THE AREA,
ENHANCED FIRE DANGER IS A CONCERN. IN ADDITION TO THE GUSTY WINDS,
HEIGHTS FALLING WELL BELOW NORMAL WILL RESULT IN COOLING TEMPS,
WITH WEEKEND HIGH TEMPERATURES TOPPING OUT SEVERAL DEGREES BELOW
NORMAL.
