...BELOW NORMAL TEMPERATURES AND TRENDING DRIER INTO THE WEEKEND...
.BROADCAST DISCUSSION...Showers and thunderstorms will continue
for much of Utah today, even as moisture starts to trend drier
from the south. Some of these showers will be capable of producing
wetting rains. Temperatures will remain below normal along with a
gradual drying trend into the weekend.
.DISCUSSION...
Monsoon moisture in place across the area will bring another day
of scattered showers and thunderstorms across Utah, which will be
efficient heavy rain producers. Thus anywhere where stronger
storms track will have a high chance of experiencing wetting
rainfall again today, along with an isolated flash flood risk.
Showers and thunderstorms will be most limited over far southern
and southwestern Utah where drier air is already starting to work
its way into the area, which will become the trend across the
entire state through through the end of the week and into the
weekend.
In the wake of the monsoon surge, temperatures will remain around
5 to 10 degrees below normal through the end of the week and into
the weekend. While RH values will remain elevated today, the
drying trend will continue through the end of the week with more
widespread minimum RH values in the teens returning this weekend
into early next week. As this occurs, the daily shower and
thunderstorm chances will trend lower and become more confined to
the terrain. Temperatures will also trend warmer this weekend,
returning to near-normal values by early next week. Not currently
expecting any elevated fire weather concerns into week as winds
appear to remain light through much of the forecast period.
