KEY MESSAGES
- HIGH PRESSURE WILL CONTINUE TO BRING HISTORICALLY WARM WEATHER
FOR MARCH TODAY.
- A DRY COLD FRONT WILL BRING A BRIEF COOLING TREND SUNDAY, THOUGH
DAYTIME HIGHS WILL REMAIN 10 TO 20 DEGREES ABOVE NORMAL.
- NEAR RECORD TEMPERATURES WILL RETURN BY TUESDAY INTO WEDNESDAY.
DISCUSSION
RECORD WARMTH CONTINUES AS A HISTORICALLY STRONG
RIDGE REMAINS IN PLACE. HIGH TEMPERATURES TODAY MAY BE KEPT DOWN A
COUPLE OF DEGREES, COMPARED TO PRIOR FORECASTS, GIVEN THE INCOMING
HIGH CLOUDS ALONG WITH A LAKE BREEZE THAT WILL KEEP AREAS NEAR THE
SOUTH END OF THE GSL A COUPLE OF DEGREES COOLER THAN AREAS FURTHER
AWAY FROM THE LAKE. REGARDLESS, TEMPERATURES WILL BE IN THE UPPER
70S TO LOW 80S WITH LOW 90S ACROSS SOUTHERN UTAH.
A DRY FRONT WILL MOVE THROUGH OVERNIGHT RESULTING IN SUNDAY HIGH
TEMPERATURES DROPPING ~10 DEGREES ACROSS NORTHERN UTAH WITH LESS
OF A DROP ACROSS SOUTHERN UTAH. HOWEVER, THIS STILL MEANS
TEMPERATURES 10-20 DEGREES ABOVE NORMALS FOR THIS TIME OF YEAR.
THE COOLER TEMPERATURES WILL BE SHORT-LIVED AS HEIGHTS BEGIN TO
BUILD AGAIN ACROSS THE REGION. BY TUESDAY, THERE IS A 70% CHANCE
THAT TEMPERATURES WILL RETURN TO THE LOW 80S AT KSLC WITH AN EVEN
HIGHER PROBABILITY OF 80 ON WEDNESDAY (80% CHANCE). THIS
PROBABILITY FALLS BACK TO 25% CHANCE ON THURSDAY AS THE RIDGE
STARTS TO FLATTEN AGAIN WITH MORE TROUGHING IN THE PNW.
THERE STILL REMAINS NO PRECIPITATION IN THE FORECAST FOR THE NEXT
7 DAYS, BUT GUIDANCE CONTINUES TO HINT AT A STORM BY THE END OF
THE MONTH WITH ~50% OF ENSEMBLE MEMBERS INTRODUCING PRECIPITATION
BY THEN.
