...WARMING AND DRYING TREND CONTINUES EARLY THIS WEEK...
.BROADCAST DISCUSSION...A warming and drying trend will continue
through Monday as high pressure builds over the region. Moisture
will slowly increase during the middle to latter portion of the
week, resulting in an increase in showers and thunderstorms
heading into next weekend.
.DISCUSSION...High pressure centered across the region will
maintain a drying and slight warming trend through Tuesday.
Daytime heating will allow afternoon cumulus will develop across
the higher terrain, and a stray afternoon shower or thunderstorm
can`t be ruled out over the Uintas Monday, and the southern
mountains Tuesday. With this ridge in place, winds will remain
light and terrain driven through Tuesday. Moisture will slowly
begin spreading back into the area by midweek, and gradually
increase through the remainder of the week. This will result in
an increasing chance for showers and thunderstorms during the
latter half of the week, as well as an upward trend in RH.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
