Area Forecast Discussion

.SYNOPSIS...A much drier northwesterly flow will spread across the
area today. Moisture will then make a quick return Thursday and
remain in place through the end of the week.


.DISCUSSION...Sunny skies are in place across Utah and southwest
Wyoming this morning, as a drier airmass continues to work into
the area from the northwest. This west-northwesterly flow is on
the south end of a broad trough that stretches from Washington to
North Dakota. Low amplitude shortwave ridging is actually in place
over Utah this morning, between the large trough and a smaller
Pacific low over southern Colorado.

While most of the forecast area is experiencing precipitable water
values less than 0.4 inches, somewhat higher PW values around 0.6
inches are still in place in southern Utah, and this is where
isolated showers and thunderstorms are expected to form later
today. Otherwise, today should remain mostly sunny and a little
cooler than usual for August.

Updated the forecast earlier to decrease cloud cover for the
morning, tweak POPs slightly for the afternoon in the San Rafael
Swell, and increase northwesterly winds across the northern half
of the CWA, as the northwesterly gradient increases through the
day. No further updates are expected this morning.


.AVIATION...VFR conditions and mostly clear skies will persist
at the SLC terminal throughout the TAF period. Light southerly winds
will shift to the northwest around 16-18Z. These northwest winds
will likely be gusty at times this afternoon, although max gusts
should remain below 30mph.
