...DRY AND WINDY TODAY...STRONG COLD FRONT SUNDAY...
.BROADCAST DISCUSSION...High-based convection with the
risk of microburst winds is expected today. Gusty winds and low
humidities will develop across portions of western Utah this
afternoon and evening. A strong cold front will cross the region
Sunday, bringing widespread valley rain and mountain snow. High
pressure will bring increasingly hot temperatures midweek.
.DISCUSSION...Two main impacts today across the region. First,
gusty winds and low humidities are expected to develop by
afternoon and across western and southern Utah. As the upper level
disturbance continues to approach the region, high-based showers
and thunderstorms will develop. This will bring the attendant
threat of strong, gusty and erratic microburst winds. A strong
cold front will cross the region Sunday, bringing falling snow
levels (as low as 6500-7000 feet at times), widespread valley rain
and mountain snow through Sunday afternoon. Another round of
precipitation is likely across central and southern Utah Monday
morning into Monday afternoon.
As high pressure builds into the region midweek, temperatures
will quickly warm to around 10 degrees above normal...with little
threat of precipitation through next weekend.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
