DESERTS DURING THE EVENING. EACH DAY`S ACTIVITY WILL  DEPEND ON HOW
THE PREVIOUS DAY SHAKES OUT. THE MAIN THREATS WITH  THESE STORMS
WILL BE STRONG, GUSTY WINDS (MAIN THREAT), EXCESSIVE  LIGHTNING, AND
LOCALIZED HEAVY DOWNPOURS. HREF PROBABILITIES, FOR  TODAY, SHOW A
30-50% CHANCE OF WINDS EXCEEDING 35 MPH ACROSS  SOUTH-CENTRAL AZ, SW
AZ, AND THE LOWER CO RIVER VALLEY AND A 10%  CHANCE OF WINDS
EXCEEDING 58 MPH OVER SW AZ. MINRHS WILL BE  AROUND 15-20% THROUGH
THE WEEKEND, WITH FAIR OVERNIGHT RECOVERIES.
