KEY MESSAGES

CONDITIONS THROUGH AT LEAST NEXT SUNDAY.
- LOW PRECIPITATION CHANCES RETURN AS EARLY AS NEXT MONDAY (FEB.
9TH).
DISCUSSION
HIGH PRESSURE WILL DOMINATE THE PATTERN OVER THE
NEXT SEVEN DAYS, WITH DRY AND MILD CONDITIONS PERSISTING ACROSS
UTAH AND SOUTHWEST WYOMING. A GRAZING SHORTWAVE TROUGH ON MONDAY
WILL BRING TEMPORARY COOLER TEMPERATURES ALOFT, ACTING TO KEEP
VALLEY INVERSIONS FROM STRENGTHENING TOO MUCH TO START THE WORK
WEEK. HOWEVER, AS A HIGHLY AMPLIFIED RIDGE BUILDS AND MOVES
OVERHEAD BY THURSDAY, INVERSIONS WILL BECOME MORE STOUT, RESULTING
IN VALLEY HAZE DEVELOPMENT AND LIMITED WARMING ACROSS VALLEYS.
ACROSS HIGHER ELEVATIONS, HOWEVER, TEMPERATURES WILL CONTINUE TO
WARM TO 10-15 DEGREES ABOVE NORMAL. CHANCES FOR NOCTURNAL VALLEY
FOG COULD RETURN DURING THE WEEK AS INVERSIONS PERSIST.
FINALLY, BY NEXT MONDAY (FEB. 9TH), PRECIPITATION CHANCES
RETURN...ALBEIT FAIRLY LOW AT FIRST. BY MONDAY, 55% OF ENSEMBLE
MEMBERS FAVOR NEGATIVE 500-MB HEIGHT ANOMALIES ACROSS PORTIONS OF
THE WESTERN US, SUGGESTIVE OF A MORE ACTIVE PATTERN. EVEN THE
REMAINING 45% SUGGEST NEGATIVE ANOMALIES AROUND 1-3 DAYS LATER
THAN THE INITIAL MAJORITY. HOWEVER, QPF/SNOWFALL PROBABILITIES
ARE STILL LOW. AROUND 10-20% OF LARGE-SCALE ENSEMBLE MEMBERS SHOW
MEASURABLE PRECIPITATION (>0.01") BY MONDAY MORNING, INCREASING TO
40-60% BY TUESDAY. WHILE THESE NUMBERS ARE NOT TERRIBLY EXCITING,
THIS IS AT LEAST AN IMPROVEMENT FROM 0% PROBABILITIES THIS WEEK!
THE CLIMATE PREDICTION CENTER EVEN SUGGESTS UTAH AND SOUTHWEST
WYOMING SLIGHTLY LEAN TOWARDS ABOVE-NORMAL PRECIPITATION IN THE
8-14 DAY TIMEFRAME.
