.DISCUSSION...Dry, breezy conditions late this afternoon and early
this evening will give way to a period of drainage winds for most of
the night before south to southeasterly winds begin to develop late
tonight. Humidity recovery will be minimal tonight. However, as an
area of low pressure and strong cold front begin to move across the
west coast on Sunday, moisture will begin to gradually increase across
northern Utah. Enough moisture will be in place by late Sunday afternoon
to allow for the development of isolated showers, with isolated showers
and evening thunderstorms Sunday night. Humidity will begin to increase
slightly on Sunday as well. A more substantial increase in moisture will
arrive Monday, along with a good chance of wetting rains from scattered
showers and thunderstorms. A cold front will move through Monday evening,
while the area of low pressure passes near the Utah/Idaho border on
Tuesday. This will bring cool, showery conditions to the area on Tuesday.
Cool temperatures along with periodic showers will then persist through
next Friday.
