.DISCUSSION...Southerly winds will stay gusty this afternoon and
ahead of an approaching Pacific storm system. Moisture will also
increase somewhat, allowing for widely scattered showers and
thunderstorms in the vicinity of the burn this afternoon. Moisture
will increase further tomorrow with decreasing winds as the trough
moves across Utah. This will bring widespread showers and a few
thunderstorms with a high likelihood of wetting rain. Drier
conditions will develop for the middle to latter part of the week
with a gradual warming trend.
