20-FOOT WIND FORECAST OF 'LIGHT WINDS' INDICATES MAINLY
TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
DISCUSSION
THE COMBINATION OF A SHIFTING WEATHER PATTERN
ALOFT AND DEEP MOISTURE RESIDING ACROSS THE REGION WILL RESULT IN
SCATTERED SHOWERS AND THUNDERSTORMS THE NEXT COUPLE DAYS ACROSS
SOUTHEAST ARIZONA WITH THE POTENTIAL FOR HEAVY RAIN. ALTHOUGH MOST
OF THE STORMS WILL PRODUCE BETWEEN A HALF AND ONE INCH OF RAIN, THE
STRONGER STORMS ARE CAPABLE OF PRODUCING LOCALLY HEAVIER AMOUNTS
BETWEEN 1-3 INCHES. OTHERWISE, A DRIER SOUTHWEST FLOW ALOFT WILL
BRING A DOWNTURN IN DAILY STORM ACTIVITY FRIDAY INTO THE WEEKEND.
MINIMUM RELATIVE HUMIDITY WILL BE 20-40 PERCENT THROUGH THURSDAY
LOWERING TO AROUND 15-30 PERCENT THEREAFTER. TEMPERATURES WILL BE
BELOW NORMAL TODAY AND THURSDAY, THEN WARM UP AGAIN FOR THE WEEKEND.
OUTSIDE OF THUNDERSTORMS, WINDS TERRAIN DRIVEN TO AROUND 10 MPH WITH
OCCASIONAL AFTERNOON GUSTS TO 20 MPH.
