AVIATION /18Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 1024 AM MST SUN MAR 1 2026
SHOWERS/POCKETS OF LIGHT RAIN WILL PERSIST THROUGH THIS EVENING,
WITH MVFR/IFR POSSIBLE AT TIMES. OTHERWISE, EXPECT VFR WEATHER
DURING THIS PERIOD. OVERNIGHT AND TOMORROW MORNING, ONE OR MORE
AREAS OF WIDESPREAD AND POTENTIALLY HEAVIER RAIN AND SNOW IS
EXPECTED...BASED ON THE HIGHER RESOLUTION MODELS. ONCE THIS AREA
OF PRECIPITATION MOVES IN, LOOK FOR A RAPID DROP TO IFR
CONDITIONS DUE TO LOW CEILINGS AND/OR VISIBILITY (ESPECIALLY IF
SNOW DEVELOPS IN AREAS WHERE WE ARE CLOSER 32-35 DEGREES). THERE
IS A 10-20% CHANCE OF GOING LIFR AT THIS POINT BASED ON TRENDS.
