A FEW FLURRIES HAVE BEEN OBSERVED UNDERNEATH THE BROKEN STRATUS

HAVE MOSTLY REMAINED UNIMPACTFUL. THE EXCEPTION TO THIS IS IN
EASTERN BOTTINEAU COUNTY WHERE RECENT SURFACE OBSERVATIONS AND

SNOW SHOWERS. CHANCES FOR FLURRIES AND/OR LIGHT SNOW SHOWERS
ACROSS THE ENTIRE AREA SHOULD DIMINISH THROUGH THE EVENING. THE

RIVER VALLEY WITH A WINTRY MIX POSSIBLE AS WELL. THE TIMING OF
