KEY MESSAGES
- HIGH PRESSURE WILL CONTINUE TO BRING HISTORICALLY WARM WEATHER

CHALLENGE MONTHLY RECORDS.
- 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.
- THERE IS LESS THAN A 5 PERCENT CHANCE OF MEASURABLE
PRECIPITATION FOR THE NEXT 7 DAYS ACROSS MOST OF UTAH AND
SOUTHWEST WYOMING.
DISCUSSION
STRONG HIGH PRESSURE OVER THE AREA TODAY WILL BEGIN
TO FLATTEN AND SHIFT EAST ON SATURDAY AS A COUPLE OF LOW-
AMPLITUDE WAVES RIPPLE FROM WEST TO EAST NEAR THE CANADIAN
BORDER. WHILE H7 TEMPERATURES WILL COOL SLIGHTLY ON SATURDAY AS
HEIGHTS FALL, MIXING WILL INCREASE IN MANY AREAS DUE TO INCREASED
WEST TO SOUTHWESTERLY FLOW, WHICH WILL HELP MAINTAIN SURFACE
TEMPERATURES AROUND 25 DEGREES ABOVE NORMAL, WITH MANY AREAS ONCE
AGAIN EXPECTED TO BREAK DAILY TEMPERATURE RECORDS.
A DRY COLD FRONT WILL SPREAD SOUTH INTO UTAH SATURDAY NIGHT INTO
SUNDAY, RESULTING IN TEMPERATURES TRENDING AROUND 10-15 DEGREES
COOLER ACROSS NORTHERN UTAH AND UP TO 8 DEGREES COOLER ACROSS
SOUTHERN UTAH FOR SUNDAY. HOWEVER, THIS WOULD ONLY LOWER
TEMPERATURES TO 10-20 DEGREES ABOVE NORMAL. THEREAFTER,
TEMPERATURES WILL REBOUND, WITH DAILY RECORD HIGHS A STRONG
POSSIBILITY FOR MANY SITES ONCE AGAIN ESPECIALLY BY MIDWEEK. THE
NBM HAS A 54% CHANCE OF SLC RETURNING TO AT LEAST 80F ON TUESDAY,
AND A 78% CHANCE ON WEDNESDAY.
ANOTHER DRY COLD FRONT LOOKS LIKE A POSSIBILITY FOR THURSDAY,
ALTHOUGH SOME OF THE LATEST DETERMINISTICS ARE LESS ENTHUSIASTIC
WITH THIS SOLUTION. OVERALL MODEL TRENDS DO CONTINUE TO INDICATE
A COOLING TREND, BUT MODEL SPREAD REMAINS FAIRLY LARGE. THE NBM
25TH-75TH PERCENTILE RANGE FOR THE MAX TEMPERATURE AT SLC ON
THURSDAY IS 63-78F. HOWEVER, EVEN AT THE LOWER END OF THE
PROBABILISTIC SPECTRUM, WE ARE ONCE AGAIN STILL LOOKING AT ABOVE-
NORMAL VALUES FOR THIS TIME OF YEAR.
AVIATION...KSLC
CLEAR TO MOSTLY CLEAR SKIES WITH PREVAILING VFR
AND LIGHT DIURNALLY TYPICAL WINDS HOLD INTO SATURDAY EVENING. HIGH
CLOUDS WILL BEGIN TO INCREASE AHEAD OF A DRY COLD FRONTAL BOUNDARY,
WHICH WILL MOVE THROUGH AROUND 02Z TO 05Z SUNDAY. THIS WILL BE
MARKED BY A PERIOD OF MODEST ENHANCEMENT TO NW WIND MAGNITUDES.
REST OF UTAH AND SOUTHWEST WYOMING
AREA TERMINALS ONCE AGAIN CAN
EXPECT THE TAF PERIOD TO SEE PREVAILING VFR CONDITIONS, SKIES
GENERALLY CLEAR TO MOSTLY CLEAR, AND LARGELY DIURNALLY NORMAL WINDS.
HIGH CLOUDS WILL BEGIN TO INCREASE AS A DRY COLD FRONT SAGS SOUTH
LATER SATURDAY. THIS FRONT WILL BEGIN TO PUSH THROUGH NORTHERN
TERMINALS SATURDAY EVENING, BRINGING A PERIOD OF SLIGHTLY ENHANCED
N TO NW WINDS.
