DISCUSSION
ISSUED AT 201 AM MDT SUN MAR 22 2026
TODAY WILL SEE A BIT OF A REPRIEVE IN THE UNPRECEDENTED EARLY
SPRING HEAT, AS A WEAK COLD FRONT HAS PUSHED ACROSS CENTRAL
WYOMING. SOME GUSTY NORTH WINDS HAVE BROUGHT COOLER TEMPERATURES
INTO THE STATE, BUT THESE TEMPERATURES ARE STILL WELL ABOVE
NORMAL FOR MID-MARCH. HIGHS TODAY WILL "ONLY" BE IN THE 50S AND
60S, ABOUT 10 DEGREES ABOVE NORMAL. THE FRONT HAS BROUGHT SOME
LIGHT PRECIP TO THE BIGHORN RANGE, BUT ANY ACCUMULATIONS HAVE
BEEN NEGLIGIBLE. AS THIS FRONT WASHES OUT THIS AFTERNOON, WEST
TO SOUTHWEST WINDS RETURN, AND WITH RIDGING BUILDING BACK IN,
TEMPERATURES WILL START TO INCREASE BACK INTO THE 60S AND 70S
INTO THE MIDDLE OF THIS WEEK. THE RIDGE WILL BE SLIGHTLY FARTHER
SOUTH, SO THE EXTREME HEAT WILL BE HELD BACK, AND THIS WILL ALSO
OPEN THE DOOR FOR SOME PRECIP TO MOVE BACK INTO THE NORTHWEST
MOUNTAIN RANGES AND THE PARKS. TEMPERATURES LOOK WARM ENOUGH TO
PRODUCE LIGHT RAIN DURING THE DAY AND LIGHT SNOW DURING THE
OVERNIGHT HOURS. MOISTURE WITH THIS IMPULSE LOOKS VERY LIMITED,
SO OVERALL ACCUMULATIONS REMAIN MINIMAL.
ANOTHER WEATHER SYSTEM APPROACHES ON WEDNESDAY. AHEAD OF THIS
SYSTEM, WINDS ARE EXPECTED TO INCREASE CONSIDERABLY. THIS ALONG
WITH VERY DRY AIR WILL BRING ANOTHER THREAT FOR FIRE WEATHER
ACROSS MOST OF THE STATE WEDNESDAY AFTERNOON.
