1255 PM MDT SUN AUG 9 2026
..MONSOON MOISTURE INCREASES THIS WEEK
BROADCAST DISCUSSION
MONSOONAL MOISTURE WILL CONTINUE TO
INCREASE STATEWIDE THIS WEEK, BRINGING IMPROVING RELATIVE
HUMIDITIES, INCREASINGLY WET STORMS, AND AN INCREASING THREAT OF
LIGHTNING. TODAY, STORMS WILL FEATURE A MIX OF STRONG OUTFLOW
WINDS STATEWIDE AND WETTING RAINS PRIMARILY ACROSS THE SOUTH.
DISCUSSION
MONSOONAL MOISTURE WILL CONTINUE TO GRADUALLY
INCREASE STATEWIDE THROUGH AT LEAST WEDNESDAY, RESULTING IN
INCREASING COVERAGE OF SHOWERS AND THUNDERSTORMS, PARTICULARLY
ACROSS HIGHER TERRAIN. TODAY, STORMS WILL FEATURE A MIX OF STRONG
OUTFLOW WINDS STATEWIDE AND SOME WETTING RAINS PRIMARILY ACROSS
SOUTHERN UTAH. WIND GUSTS COULD REACH 50-60 MPH WITH COLLAPSING
STORMS. AS MOISTURE CONTINUES TO INCREASE THIS WEEK, RELATIVE
HUMIDITIES AND WETTING RAIN CHANCES WILL INCREASE ALONGSIDE
DECREASING TEMPERATURES. DAILY AFTERNOON SHOWERS AND THUNDERSTORMS
WILL PERSIST LIKELY THROUGH THE WEEK, WITH FAIRLY LIGHT WINDS
EXPECTED OUTSIDE OF ANY OUTFLOW.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
***ALL WINDS ARE 20 FOOT, 10-MINUTE AVERAGES***
