pattern for Southeast Arizona develops Wednesday into Thursday.
The primary hazard with these storms will be heavy rainfall
leading to localized flash flooding with a secondary hazard of
strong outflow winds. Temperatures will be around normal to a
few degrees below normal into early next week. Minimum relative
humidity values mainly 20 to 45 percent in the valleys and 30 to
60 percent in the mountains over the next week. Winds will
generally remain less than 15 mph and terrain driven through the
week.
