335 PM MST WED FEB 4 2026
KEY MESSAGES

WEEKEND FOR MOST OF THE AREA.
- A TROUGH EARLY NEXT WEEK WILL BRING VALLEY RAIN AND MOUNTAIN
SNOW TO MOST OF THE AREA, BUT DETAILS REMAIN UNCERTAIN.
DISCUSSION
HIGH PRESSURE REMAINS IN PLACE ACROSS THE WEST
RESULTING IN TEMPERATURES 10 TO 15 DEGREES ABOVE NORMAL. A HIGHER
SUN ANGLE HAS LED TO BETTER DIURNAL MIXING THAT HAS LIMITED THE
AMOUNT OF HAZE THAT HAS BEEN ABLE TO DEVELOP DURING THESE WEAK
VALLEY INVERSIONS. IT WILL BE HARD TO ESTABLISH THESE STRONGER
INVERSIONS OVER THE COMING DAYS GIVEN THE LACK OF COLD AIR AND
MOISTURE.
A WEAK WAVE WILL BE MOVING THROUGH THE MOJAVE ON FRIDAY. THE
DYNAMICS WITH THIS ARE WEAK ALONG WITH LIMITED MOISTURE, BUT A
SPOTTY SHOWER CAN'T BE RULED OUT ACROSS SOUTHERN UTAH DURING THE
DAY ON FRIDAY.
THE NEXT STORM HAS TRENDED A BIT SLOWER IN THE GUIDANCE. INTIALLY,
THIS WAS SLATED TO ARRIVE ON MONDAY, BUT GUIDANCE IS STARTING TO
PUSH THIS BACK TO EARLY TUESDAY. ADDITIONALLY, H700 TEMPERATURES
HAVE TRENDED WARMER WITH VALLEY RAIN AND MOUNTAIN SNOW NOW THE
PRIMARY SCENARIO. THERE STILL REMAINS A LARGE SPREAD IN THE H700
TEMPERATURES, BUT EVEN THE 25TH PERCENTILE TEMPERATURES ONLY GETS
DOWN TO ~-9C WHICH WOULD START TO GET INTO THE REALM TO INTRODUCE
VALLEY SNOW, BUT MOISTURE MAY BE WANING BY THE TIME THE COLDEST
AIR ARRIVES. ALL THAT TO SAY, THERE IS STILL A LARGE UNCERTAINTY
REGARDING HOW THIS STORM WILL UNFOLD. IT IS STILL 6 DAYS AWAY SO
THERE WILL BE MANY ITERATIONS OF HOW THIS WILL PLAY OUT IN THE
COMING DAYS FROM THE ENSEMBLE MEMBERS.
