...TRENDING DRIER AND WARMER...
.BROADCAST DISCUSSION...A general drying and warming trend will
bring a decreasing threat of showers and thunderstorms into the
weekend.
.DISCUSSION...Moisture will continue to decrease across the area
today. While showers and thunderstorms are expected once again,
they will be more isolated to widely scattered in coverage and
will have a smaller potential for wetting rain. Tonight, a brief
increase in moisture is expected for southern and portions of
central Utah as remnants of a tropical system ejects across the
desert southwest and into southern Utah, bringing an area of light
to potentially moderate rain. Most of this moisture will be out of
Utah by tomorrow afternoon, but there will be enough to maintain
isolated to widely scattered showers and thunderstorms through the
afternoon. Over the weekend, much drier conditions are
anticipated, and any showers will be quite isolated and confined
to near the higher terrain. Afternoon relative humidities will
fall into the teens and low 20s for most valley areas this
weekend. Temperatures will also gradually trend warmer into the
weekend, although not reaching climatological normals until Sunday
for most areas. Next week, a modest increase in moisture will
bring increased shower and thunderstorm activity back to the area.
However, wetting rain chances with these showers are likely to
remain low.
***Thunderstorms imply strong, gusty and erratic winds***
