DISCUSSION
SPOTTY SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS SOUTH-CENTRAL
AZ THROUGH THIS AFTERNOON AND EVENING, WITH ANY STORM THAT
DEVELOPS CAPABLE OF PRODUCING GUSTY WINDS AND WETTING RAINS, GIVEN
HIGH MOISTURE LEVELS. BEST CWRS, 30-50%, ARE IN THE HIGH TERRAIN
EAST OF PHOENIX WITH 5-20% IN THE LOWER DESERTS. LINGERING SHOWERS
AND STORMS TOMORROW AFTERNOON WILL EXCLUSIVELY BE FOCUSED TOWARD
THE WHITE MOUNTAINS EAST OF GLOBE. WHERE WESTERN AREAS ARE ALREADY
DRY, EASTERN AREAS WILL EXHIBIT A RAPID DRYING TREND THROUGH
WEDNESDAY AND INTO THURSDAY WITH BELOW NORMAL TEMPERATURES SLOWLY
WARMING BACK NEAR NORMAL THURSDAY. MINIMUM AFTERNOON HUMIDITY
VALUES RANGING FROM 15% IN WESTERN DISTRICTS TO 40% IN EASTERN
DISTRICTS TODAY WILL DETERIORATE INTO A 5-10% RANGE FOR ALL
DISTRICTS BY THURSDAY. SIMILARLY, FAIR TO GOOD OVERNIGHT RECOVERY
OF 30-70% WILL RETREAT INTO A POOR TO FAIR RANGE OF 20-40%
BEGINNING TOMORROW NIGHT. WINDS SHOULD BE FAIRLY TYPICAL FOR THE
SEASON THROUGH THE WEEK WITH ONLY THE USUAL AFTERNOON UPSLOPE
GUSTINESS.
..THUNDERSTORMS IMPLY GUSTY WINDS
