DISCUSSION
THERE IS A MARGINAL RISK FOR STRONG STORMS THIS AFTERNOON
ACROSS NORTHERN UTAH AS MORE STORMS DEVELOP ACROSS MOST OF THE
STATE TODAY. THESE STORMS WILL BE LOCALLY STRONGER ACROSS NORTHERN
UTAH AS THEY WILL POSSESS A GREATER RISK FOR GUSTY WINDS. 3PM-7PM
IS THE MOST LIKELY WINDOW OF IMPACTS FROM THESE STORMS. THESE
STORMS WILL TRANSITION TO ISOLATED RAIN SHOWERS LATER IN THE
EVENING WITH A LOW (30% CHANCE) OF MORE RAIN OVERNIGHT.
WINDS WILL STRENGTHEN OUT OF THE SOUTHWEST FRIDAY AND SATURDAY AS
A LOW PRESSURE SYSTEM MOVES INTO THE PNW AND EVENTUALLY BRINGS A
COLD FRONT THROUGH THE REGION ON SATURDAY. MOISTURE WILL ALSO
INCREASE FRIDAY AND SATURDAY AS TROPICAL MOISTURE FROM THE PACIFIC
IS PULLED INTO THE AREA. THIS WILL INCREASE PRECIPITATION
COVERAGE, PARTICULARLY ACROSS CENTRAL AND NORTHERN UTAH FRIDAY AND
SATURDAY. THE COLD FRONT WILL ARRIVE ON SATURDAY WHICH WILL
INTERACT WITH THE TROPICAL MOISTURE TO PRODUCE WIDESPREAD HEAVY
PRECIPITATION THAT WILL GREATLY INCREASE THE CHANCES FOR WETTING
RAINS. TEMPERATURES WILL ALSO TREND DOWN WITH THE INCREASED
MOISTURE AND COOLER AIR ARRIVING BEHIND THE COLD FRONT.
