...GUSTY WINDS ACROSS WESTERN UTAH THIS WEEKEND...
.BROADCAST DISCUSSION...Elevated southerly flow aloft keeps
conditions dry with gusty winds today, especially across the
western half of Utah. A tropical system brings increasing moisture
across the region starting Sunday into early next week, resulting
in an uptick in RH values statewide with increasing chances for
showers and thunderstorms through this period.
.DISCUSSION...Increasing southerly flow aloft through the
remainder of the weekend will result in gusty afternoon winds
developing across the western portion of the state through Sunday,
with widespread gusts 25-30 mph. While conditions remain dry
today, especially across portions of southern Utah where daytime
RH values dip to near-critical, improving overnight recoveries
tonight will limit the fire weather risk overall. Moisture
associated with two tropical systeams in the Eastern Pacific will
increase steadily on Sunday, with best moisture availability focused
across southern and eastern Utah. This will result in scattered
showers and thunderstorms developing across these areas on Sunday
afternoon, with the main threat being gusty and erratic outflow
winds as lower levels remain relatively dry. Deep moisture
overspreads the region Monday into Tuesday; concurrently, an
upper-level wave traversing the western US will result in ample
instability developing across southern and eastern Utah on Monday
afternoon. This increasing instability will interact with deep
tropical moisture, resulting in more widespread showers and
thunderstorms capable of producing heavy rainfall and better
chances for widespread wetting rains through Tuesday morning.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
