PER PREVIOUS THINKING SNOW SHOULD BE ACCUMULATING ACROSS THE CENTRAL AND SOUTHWEST MOUNTAINS IN THE MORNING...AND CONTINUING THROUGH THE AFTERNOON. LATEST NAM12 GUIDANCE HAS SIGNIFICANT ACCUMULATION IN THE HIGHEST TERRAIN OF THE EASTERN SAN JUANS (WOLF CREEK PASS) IN THE AFTERNOON.

THREAT OF FREEZING RAIN SHOULD VANISH EARLY...AS THE THREAT OF HIGH WINDS EMERGES.
