This Hazardous Weather Outlook is for the western two thirds of

.DAY ONE...Today and Tonight

Showers and thunderstorms will form across much of the outlook
area again today. Heavy rain will be a possibility, leading to an
increased threat of flash flooding, especially along prone
drainages in southern and central Utah.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Drier air will spread into northern Utah Friday into Saturday,
but moisture will remain in place across southern through east-
central Utah where showers and thunderstorms will continue. Sunday
will likely be drier across most of the area.

More significant moisture will return to the entire outlook area
starting Monday, bringing an increased chance of showers and
thunderstorms for the first half of next week. Some of these
storms may produce heavy rainfall.


Weather spotters are encouraged to report significant weather
conditions according to standard operating procedures.
