NORTHWEST ARIZONA AND SOUTHEAST CALIFORNIA
NATIONAL WEATHER SERVICE LAS VEGAS NV
220 AM PDT FRI AUG 28 2026
DISCUSSION
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED ACROSS THE REGION TODAY AND TOMORROW. STRONG OUTFLOW
WINDS, FREQUENT LIGHTNING, AND LOCALIZED HEAVY RAIN ARE THE
PRIMARY CONVECTIVE THREATS. EXPECT ANOTHER DAY OR TWO OF HOTTER
THAN NORMAL TEMPERATURES ACROSS THE MOJAVE DESERT, WITH COOLER
THAN NORMAL TEMPERATURES EXPECTED NEXT WEEK. RELATIVE HUMIDITIES
WILL BOTTOM OUT IN THE 15 TO 30 PERCENT RANGE EACH AFTERNOON FOR
MUCH OF THE REGION. OUTSIDE OF CONVECTIVE INFLUENCE, WINDS WILL
TEND TO FOLLOW TYPICAL TERRAIN DRIVEN DIRECTIONAL TRENDS DURING
THE OVERNIGHT AND EARLY MORNING HOURS WITH BREEZY SOUTHERLY TO
SOUTHWESTERLY WINDS IN THE AFTERNOON.
NOTE: THUNDERSTORMS IMPLY GUSTY AND ERRATIC WINDS.
