PERSISTENT SNOW SQUALLS ARE EXPECTED TO DEVELOP. UNDER THE SNOW  SQUALL BANDS, VISIBILITIES WILL BE SIGNIFICANTLY REDUCED DUE TO THE HEAVY SNOW COMBINED WITH BLOWING SNOW, AND SNOW WILL QUICKLY ACCUMULATE.

THERE IS POTENTIAL FOR SNOW SQUALLS TO DEVELOP BEGINNING THIS MORNING. LOCAL SNOWFALL AMOUNTS NEAR 15 CM ARE POSSIBLE FROM THE SNOW SQUALLS, ALONG WITH SUDDEN NEAR ZERO VISIBILITY IN BURSTS OF HEAVY SNOW AND LOCAL BLOWING SNOW.
