KEY MESSAGES
- MOSTLY DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES ARE
EXPECTED TODAY BEFORE A COOL DOWN TUESDAY AND WEDNESDAY (NEAR
NORMAL). TEMPERATURES RETURN TO ABOVE NORMAL TEMPERATURES THE
REMAINDER OF THE WEEK AND INTO NEXT WEEK.
- STRONG AND GUSTY WESTERLY WINDS WILL DEVELOP ON MONDAY AND
PERSIST THROUGH THE WEEKEND ACROSS SOUTHWEST WYOMING AND ALONG
THE RIDGETOPS AND LEEWARD SIDE OF TERRAIN OF CENTRAL AND
NORTHERN UTAH.
DISCUSSION
WELL ABOVE NORMAL TEMPERATURES BUILD INTO UTAH AND
SOUTHWEST WYOMING TODAY AS SOUTHWEST WINDS SPREAD ACROSS THE
REGION. ACROSS MUCH OF THE AREA, HIGH TEMPERATURES WILL RUN ABOUT
10-15 DEGREES ABOVE CLIMATOLOGICAL NORMALS WITH SOUTHWEST WINDS
GUSTING TO AROUND 25-30 MPH ACROSS WESTERN UTAH. FOR SOUTHWEST
WYOMING, CLOSER PROXIMITY TO THE ACTIVE JET STREAM TO OUR NORTH
WILL HELP TO BRING AFTERNOON WIND GUSTS OF UP TO 35 TO 40 MPH.
NONETHELESS, LARGELY UNIMPACTFUL WEATHER WILL PREVAIL TODAY ACROSS
THE REGION.
WITH THE ACTIVE JET STREAM LINGERING TO THE NORTH, THE BATTLE
BETWEEN A SPRING AIRMASS AND WINTER AIRMASS WILL PERSIST. THIS JET
STREAM, AND THE ASSOCIATED TROUGH, WILL DIP SOUTHWARD (MAINLY
EAST OF THE AREA) WHICH WILL HELP TO INTRODUCE A LARGELY DRY COLD
FRONT TO THE NORTHERN HALF OF UTAH AND SOUTHWEST WYOMING. THIS
BOUNDARY WILL DRAPE ACROSS THE AREA FROM EARLY TUESDAY THROUGH
WEDNESDAY BEFORE RETREATING NORTHWARD LATE IN THE WEEK. AS SUCH,
WE'LL SEE TEMPERATURES TREND BACK TOWARD CLIMATOLOGICAL NORMALS
FOR THIS TIME OF YEAR FOR TUESDAY AND WEDNESDAY. AS THE BOUNDARY
SAGS SOUTHWARD EARLY TUESDAY MORNING, THERE WILL BE GENERALLY LOW
PROBABILITY (20% OR LESS) OF LIGHT SNOW SHOWERS (TOTAL SWE
POTENTIAL LESS THAN 0.1 INCHES) IN THE HIGH TERRAIN ACROSS
NORTHERN UTAH. OTHERWISE, ANTICIPATE DRY AND COOLER CONDITIONS FOR
BOTH TUESDAY AND WEDNESDAY ACROSS THE FORECAST AREA.
HEADING THROUGH THE SECOND HALF OF THE WEEK, THERE IS HIGH
CONFIDENCE IN A RIDGE OF HIGH PRESSURE REESTABLISHING ACROSS THE
REGION WHICH WILL HELP TO BRING THE RETURN OF ABOVE NORMAL
TEMPERATURES (+10-15 DEGREES) FROM THURSDAY AND BEYOND.
THE BIGGEST UNCERTAINTY WITH THE FORECAST ARISES AS WE HEAD INTO
THE WEEKEND AS THE LONGWAVE TROUGH TO OUR NORTHEAST WILL SEE A
SHORTWAVE PROGRESS INLAND FROM THE SOUTHERN B.C. REGION.
CURRENTLY, THERE ARE ABOUT 25-40% OF ENSEMBLE MEMBERS THAT BRING
THIS SHORTWAVE IN CLOSE ENOUGH PROXIMITY TO NORTHERN UTAH/
SOUTHWEST WYOMING TO PROVIDE ENOUGH LIFT AND MOISTURE TO SPREAD
LIGHT PRECIPITATION AND A WEAK COLD FRONTAL BOUNDARY ACROSS THIS
AREA. PROBABILITY OF SEEING NOTEWORTHY PRECIPITATION (0.1 INCHES
OR GREATER) ON SATURDAY AND SUNDAY IS QUITE LOW AT THIS TIME
(AROUND 10%). THEREAFTER, THERE IS STRONG MODEL AGREEMENT ON A
SIGNIFICANT RIDGE BUILDING INTO THE WESTERN U.S. WHICH WILL ALLOW
TEMPERATURES TO INCREASE EVEN MORE... AND COULD EVEN GIVE US A RUN
AT OUR FIRST 80 DEGREE DAY IN SALT LAKE CITY (50% CHANCE BY
THURSDAY). IF WE CAN ACHIEVE 80 DEGREES NEXT WEEK, IT WILL BE THE
EARLIEST 80 DEGREE DAY ON RECORD (CURRENT RECORD: MARCH 31).
AVIATION...KSLC
GUSTY SOUTH WINDS WILL PREVAIL THROUGH THE
EARLY AFTERNOON HOURS WITH FLOW WEAKENING AND TRANSITIONING TO A
NORTHWESTERLY FLOW AROUND 21Z. NORTHWESTERLY WINDS MAY OCCUR AS
EARLY AS 20Z (15-20% CHANCE) AND AS LATE AS 23Z (20% CHANCE).
OTHERWISE, EXPECT VFR CONDITIONS THROUGH THE TAF PERIOD WITH CIGS
LOWERING TO AROUND 12KFT AGL DURING THE OVERNIGHT HOURS.
REST OF UTAH AND SOUTHWEST WYOMING
VFR CONDITIONS AND GUSTY
SOUTHWEST WINDS ARE EXPECTED ACROSS UTAH AND SOUTHWEST WYOMING
THROUGHOUT THE VALID TAF PERIOD. ACROSS THE WESTERN HALF OF UTAH,
PEAK WIND GUSTS ARE EXPECTED TO BE AROUND 25KTS. FOR SOUTHWEST
WYOMING, GUSTS MAY BE AS HIGH AS 35KTS. GUSTY WINDS WILL DECREASE
AFTER SUNDOWN, HOWEVER, A WEAK COLD FRONTAL BOUNDARY WILL BRING A
NORTHERLY WIND SHIFT OVERNIGHT AND EARLY TUESDAY MORNING.
