in over the Great Basin. Most models continue to show some
instability over the highest terrain late this afternoon into this
evening but there has been some backing off. Will continue with
current forecast of slight chance of showers and thunderstorms and
leave it at that.

The trend over the next few days will be for the ridge to move to
our east opening the door for some southerly flow to develop. This
southerly flow will tap some moisture resulting in an increase
of showers and thunderstorms as we move into mid week.


Hydrology...the ridge building over the area will bring with it
temperatures 10-15 degrees above normal which will increase the
snow melt across the high elevations. Rivers across northern Utah
will run fast and cold this week. Several rivers will approach or
go above bankfull by midweek, specifically the headwaters of the Weber
and Provo. Meanwhile, the Logan river is projected to go above
flood stage by Tuesday. See the latest Flood Watch statement

conditions will prevail today under sunny skies.
