THE PERSISTENT SOUTHWESTERLY FLOW PATTERN WILL CONTINUE THROUGH THE
WEEKEND. A PIECE OF ENERGY FROM THE REMNANTS OF DOUGLAS WILL ADVECT
THROUGH THE REGION SATURDAY NIGHT AND SUNDAY. DESPITE WEAK MOISTURE
INCREASES AND MODEST FORCING WITH THIS WAVE, THINK THE DRY FORECAST

SOME WEAK RADAR RETURNS SATURDAY NIGHT AND AGAIN SUNDAY AFTERNOON,
MAINLY IN THE LOWER COLORADO RIVER VALLEY AND MOHAVE COUNTY, BUT
PROBABILITIES ON ENSEMBLES FOR MEASURABLE RAINFALL IS 10% OR LESS.
WILL MONITOR THE POTENTIAL FOR SHOWERS THOUGH, ESPECIALLY SATURDAY
NIGHT AS VIRGA MAY BRING GUSTY WINDS DURING PEAK FIREWORK TIMING IF
SOMETHING DID DEVELOP. AFTER THIS WEAK IMPULSE EXITS, IT WILL
DEFINITELY REMAIN DRY THROUGH NEXT WEEK. VERY DRY CONDITIONS
COMBINED WITH AFTERNOON SOUTHWEST WINDS GUSTING TO AROUND 20 MPH
MEANS FIRES COULD EASILY START AND SPREAD- ANYONE PARTICIPATING IN
RECREATIONAL ACTIVITIES FOR THE HOLIDAY WEEKEND INCLUDING COOKING
WITH CHARCOAL GRILLS, PARTICIPATING IN TARGET PRACTICE, DRAGGING
CHAINS OFF THEIR VEHICLE, AND/OR USING SAFE-AND-SANE FIREWORKS ARE

TO EXTINGUISH FLAMES AS NECESSARY. AN UPPER LEVEL RIDGE WILL RE-
