DISCUSSION
TODAY THROUGH THANKSGIVING DAY.
A CLOSED AREA OF LOW PRESSURE WILL CONTINUE TO MEANDER COUNTER-
CLOCKWISE AROUND THE SOUTHERN EDGE OF OUR FORECAST AREA TODAY AND
SATURDAY. SCATTERED LIGHT-TO-MODERATE SHOWERS WILL CONTINUE
ACROSS OUR SOUTHERN ZONES THROUGH SATURDAY MORNING AS A RESULT,
INCLUDING SAN BERNARDINO COUNTY, THE LOWER COLORADO RIVER VALLEY,
AND SOUTHERN MOHAVE COUNTY, WITH GREATEST AMOUNTS IN THE HIGHER
TERRAIN. WIDESPREAD FLASH FLOODING IS NOT EXPECTED, BUT CANNOT
RULE OUT ISOLATED INSTANCES WHERE TRAINING SHOWERS OVER SATURATED
SOILS RESULT IN ROADWAY PONDING AND/OR WATER FLOWING THROUGH LOW
WATER CROSSINGS. FURTHER NORTH ACROSS INYO, SOUTHERN NYE, CLARK,
AND NORTHERN MOHAVE COUNTIES, SHOWERS WILL BE MORE ISOLATED IN-
NATURE, WITH MINIMAL IMPACTS FROM RAINFALL EXPECTED. WINTER
WEATHER ADVISORIES FOR THE SPRING MOUNTAINS, SHEEP RANGE, EASTERN
SIERRA SLOPES, AND WHITE MOUNTAINS WILL BE ALLOWED TO EXPIRE ON
TIME AT 8 AM PST THIS MORNING, AS THE BULK OF PRECIPITATION
THEREAFTER WILL REMAIN SOUTH OF AREA MOUNTAINS. SHOWER ACTIVITY
WILL WANE THROUGH THE DAY ON SATURDAY AS THE CENTER OF THE LOW
PUSHES EASTWARD INTO CENTRAL ARIZONA.
A RIDGE OF HIGH PRESSURE WILL NOSE INTO THE DESERT SOUTHWEST FROM
THE SOUTHEASTERN PACIFIC OCEAN OVER THE WEEKEND, ALLOWING AFTERNOON
HIGH TEMPERATURES TO MODERATE BACK TOWARD SEASONAL NORMALS. THIS
RIDGE WILL RESULT IN A DRY NORTHWEST FLOW ALOFT, WHICH IS CONDUCIVE
FOR THE PASSAGE OF SHORTWAVE WIND-MAKERS. AS A RESULT, IF YOU'RE
PLANNING TO RECREATE AT AREA LAKES NEXT WEEK, CHECK THE FORECAST
IN ADVANCE, AS GUSTY NORTH WINDS COULD RESULT IN HAZARDOUS BOATING
CONDITIONS. OTHERWISE, DRY CONDITIONS AND MOSTLY SUNNY SKIES CAN
BE EXPECTED HEADING INTO THANKSGIVING.
AVIATION...FOR HARRY REID...FOR THE 06Z FORECAST PACKAGE
LIGHT RAIN SHOWERS ARE EXPECTED THROUGH MID-MORNING. DURING THIS
TIME, LIGHT NORTHERLY WINDS WILL VEER TO BECOME EASTERLY. RAIN
SHOWERS ARE EXPECTED TO DRIFT SOUTH OF THE TERMINAL INTO THE
AFTERNOON, WITH A RETURN TOMORROW EVENING. LAS IS GOING TO BE
RIGHT ON THE EDGE OF THE RAIN SHOWER ACTIVITY, SO IT WILL LIKELY
BE A TRANSIENT TAF PERIOD BETWEEN SHRA/VCSH. NONETHELESS, AN
IMPACTFUL TAF PERIOD IS ON TAP WITH CEILINGS LIKELY BELOW FL050
FOR A MAJORITY OF IT. DIURNAL WINDS BELOW 10 KNOTS ARE EXPECTED TO
PREVAIL.
FOR THE REST OF SOUTHERN NEVADA, NORTHWESTERN ARIZONA AND
SOUTHEASTERN CALIFORNIA...FOR THE 06Z FORECAST PACKAGE...LIGHT TO
MODERATE RAIN SHOWERS WILL CONTINUE TO SPREAD EAST THROUGH THE
NIGHT. LOW-END VFR TO HIGH-END MVFR CONDITIONS AND DIURNAL WINDS

AND AROUND THE PRECIPITATION, EXPECT REDUCED VISIBILITIES, LOWERED
CEILINGS, AND SIGNIFICANT TERRAIN OBSCURATION.
