...WARM AND DRY THROUGH TUESDAY, THEN MOISTURE SLOWLY RETURNS...
.BROADCAST DISCUSSION...High pressure will maintain a warm and
dry airmass across the region through Tuesday. Moisture will
gradually increase from south to north through the second half
of the week, bringing increasing chances for showers and
thunderstorms, especially by the weekend.
.DISCUSSION...High pressure centered across the Intermountain
region will maintain a warm and dry airmass through the first
half of the week. Daytime temperatures will continue to run
around 5 degrees above normal, with low daytime RH and
marginal overnight recovery. With this high in place, winds
will remain largely terrain driven through Wednesday.
Moisture will begin to work its way back into the region as
early as late Tuesday afternoon across southwest Utah, then
gradually increase and spread northward through the latter
half of the week. This will initially bring a chance for high
based showers and dry thunderstorms late Tuesday into Wednesday
across southern Utah. By Thursday this moisture will spread
across the remainder of the area, with storms transitioning
from dry to wet Thursday into Friday. This chance for showers
and thunderstorms will continue into the upcoming weekend.
With the increase in moisture, temperatures will trend cooler
while RH trends higher for the latter portion of the week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
