Synopsis...high pressure early in the week will create excessively
hot conditions along the wastach front and northwest Utah. Monsoonal
moisture will spread into the region beginning Tuesday resulting in
an increase of afternoon thunderstorm activity through the end of
the week.


Discussion...high pressure centered near The Four Corners area this
evening will continue to strengthen through Tuesday. Temperatures
underneath this dome of high pressure will continue to rise during
this time while moisture will gradually increase across the area.
Temperatures are expected to be in the triple digits for afternoon
highs Monday and Tuesday across the Wasatch front and northwest
Utah, and the warmest so far this year. Overnight mins in the 70s
are expected to provide little relief. As such, a heat advisory is
in effect for tomorrow afternoon through Tuesday night.

Increasing moisture will allow for increasing coverage of showers
and thunderstorms through midweek. However, the dry subcloud layer
will initially result in gusty outflow winds and little rainfall.

Until then, expect quiet weather for the rest of tonight. Some
lingering showers remain in place across the uintas from earlier
thunderstorms, but these will continue to wane through the night.
Patchy mid and thin high clouds will be present across the area with
light winds.

Updated the forecast earlier for pop/sky. No further updates planned
this evening.


Aviation...southeast winds are expected to become established at
the slc terminal by 04z-05z. Expect the typical diurnal switch to
northwest from 19z-20z on Monday. VFR conditions will prevail
through the valid taf period.
