- EARLY-APRIL WARMTH: TEMPERATURES WILL REMAIN CONSISTENTLY 10
TO 15 DEGREES ABOVE SEASONAL NORMALS THROUGH MONDAY, WITH MANY
VALLEY LOCATIONS REACHING THE MID TO UPPER 60S.
- BREEZY TUESDAY TRANSITION: A POTENT STORM SYSTEM PASSING TO
OUR NORTH WILL TIGHTEN THE PRESSURE GRADIENT, BRINGING GUSTY
WINDS THAT MAY APPROACH WIND ADVISORY CRITERIA TUESDAY
AFTERNOON.
- MINIMAL PRECIPITATION: ASIDE FROM A FEW STRAY SHOWERS ALONG
THE CONTINENTAL DIVIDE ON TUESDAY, DRY CONDITIONS WILL PREVAIL
THROUGH THE WORK WEEK.
- EXTENDED MILD PATTERN: A SPLIT-FLOW ATMOSPHERIC PATTERN

REGIME HEADING INTO NEXT WEEKEND
DISCUSSION
ISSUED AT 111 PM MDT SUN APR 5 2026
BENIGN WEATHER REMAINS IN PLACE TO END THE WEEKEND ACROSS
EASTERN IDAHO AS HIGH PRESSURE STAYS IN CONTROL OF THE LOCAL
PATTERN. SATELLITE IMAGERY CURRENTLY SHOWS ONLY A FEW MID-TO-
HIGH LEVEL CLOUDS PASSING THROUGH FROM TIME TO TIME, ALLOWING
FOR AMPLE SUNSHINE TO PAIR WITH OUR SEASONABLY WARM
TEMPERATURES. DAYTIME HIGHS TODAY AND AGAIN ON MONDAY ARE
EXPECTED TO REACH THE MID TO UPPER 60S, AND IT IS LIKELY THAT A
FEW OF OUR TYPICALLY WARMER SPOTS WILL TOP 70 DEGREES BEFORE THE
AFTERNOON ENDS. THESE VALUES ARE QUITE PLEASANT FOR EARLY
APRIL, RUNNING APPROXIMATELY 10 TO 15 DEGREES ABOVE OUR CLIMATE
NORMALS. NO PRECIPITATION IS EXPECTED THROUGH THE NEXT 48 HOURS.
THE PATTERN BEGINS TO SHIFT SLIGHTLY ON TUESDAY AS A POTENT
UPPER-LEVEL TROUGH MOVES FROM WESTERN CANADA INTO THE CANADIAN
PRAIRIES. WHILE THE HEART OF THIS SYSTEM STAYS TO OUR NORTH, IT
WILL CAUSE A TIGHTENING PRESSURE GRADIENT ACROSS THE REGION,
LEADING TO A BREEZY TUESDAY AFTERNOON. WE DON'T EXPECT MUCH IN
THE WAY OF WIDESPREAD PRECIPITATION TO CONTEND WITH, THOUGH WE
COULD SEE SOME ISOLATED SHOWER CHANCES IN THE EASTERN HIGHLANDS
AND ALONG THE CONTINENTAL DIVIDE. FOR THE MOST PART, THIS SYSTEM
IS NOT EXPECTED TO BE OVERLY IMPACTFUL ASIDE FROM THE INCREASED
WIND, WHICH COULD FLIRT WITH WIND ADVISORY CRITERIA DURING THE
AFTERNOON HOURS.
AS THAT TROUGH SHIFTS WELL TO THE EAST, WEAK RIDGING WILL AGAIN
BUILD AS A MORE WIDESPREAD SPLIT UPPER-LEVEL FLOW DEVELOPS
ACROSS THE WESTERN UNITED STATES. THIS CONFIGURATION LOOKS TO
KEEP OUR AREA CHARACTERIZED BY SEASONABLY WARM TEMPERATURES AND
GENERALLY DRY WEATHER AS WE APPROACH THE FOLLOWING WEEKEND.
DAILY TEMPERATURES WILL CONTINUE TO RUN ROUGHLY 5 TO 10 DEGREES
ABOVE AVERAGE — FOR BOTH DAYTIME HIGHS AND OVERNIGHT
LOWS — THROUGHOUT MUCH OF THE FORECAST PERIOD.
AVIATION /06Z TAFS THROUGH 06Z TUESDAY/
