...WEATHER TO TREND DRIER AND MORE MILD...
.BROADCAST DISCUSSION...Moisture associated with a monsoonal pattern
will continue to gradually scour out. Precipitation and wetting
rain chances decrease accordingly, with temperatures trending back
near to slightly above normal by next week.
.DISCUSSION...Remnant moisture associated with a monsoonal pattern
will linger and result in a continued chance of scattered
convection Thursday. Overnight into early Friday, a remnant
tropical system will eject through the region, resulting in
potential for more widespread stratiform rain, particularly across
southern to central Utah. Moisture will then remain sufficient
for another day of isolated to scattered convection during the day
Friday. From the weekend on into early next week high pressure
ridging becomes better centered overhead, resulting in a drying
and warming trend. Some isolated convection will be possible
during the day, primarily along high terrain in southern Utah, but
coverage will become much less widespread than that of prior
days. Models then suggest an uptick in moisture by midweek will
result in a corresponding increase to precipitation chances once
again.
