.SYNOPSIS...High pressure will strengthen for the mid-week period,
bringing a drying trend to the state. Moisture will slowly creep
north late in the week into the weekend.
.DISCUSSION...Isolated showers and thunderstorms continue to form
across southern Tooele County and Juab County this morning due to
the front exit region of the jet intersecting with residual
moisture. The LIs, surface based cape, and the 700-500 mb theta-E
ridge with weak upglide component are all supportive in this
area. Have updated to put isolated showers and thunderstorms in
this area for this morning and into early afternoon for the Utah
Farther south, there is still deep moisture so have added the
phrase locally heavy rain with thunderstorms across the southern
tier of the CWA for this afternoon. Rest of package in good
.AVIATION...Light and variable winds are expected to shift
to the northwest between 17Z and 19Z.The SLC terminal will see
VFR conditions throughout the day with some scattered clouds.
There is a 10 percent chance of erratic gusty outflow winds from
vicinity showers to the south through about 20z.
