...WARM AND DRY TODAY, THEN MOISTURE SLOWLY RETURNS...
.BROADCAST DISCUSSION...High pressure will maintain a warm and
dry airmass across the region today. The pattern shifts Wednesday
as monsoonal moisture is gradually drawn up into the region,
yielding increasing chances for showers and thunderstorms through
the weekend. Storms will be drier in nature Wednesday, gradually
trending wetter through the remainder of the week.
.DISCUSSION...High pressure remains in place today, resulting in
continued hot and dry conditions across the region. Monsoonal
moisture is expected to gradually increase from the south starting
overnight tonight, resulting in slight improvement of overnight
humidity recoveries across southwestern Utah into Wendesday
morning. This increased moisture across southwest Utah on
Wednesday will also result in increased chances for afternoon
high-based showers and thunderstorms, with potential to produce
gusty and erratic outflow winds. Moisture will continue to deepen
and spread northward Thursday through this weekend, allowing
storms to trend wetter and coverage to become more widespread
through the latter half of the week. Temperatures are also
expected to gradually cool in response to this push of monsoonal
moisture, with highs running a few degrees below normal by the
weekend.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
