MORNING THROUGH AFTERNOON. WINDS ARE GENERALLY EXPECTED TO BE
LIGHT THROUGH MUCH OF TODAY...BUT COULD BE OCCASIONALLY GUSTY AND

UP LATE IN THE DAY AND CONTINUE THROUGH THE WEEKEND. THERE IS A

QUESTION. SNOW LEVELS THROUGH THIS EVENT ARE GENERALLY EXPECTED

MIX...PARTICULARLY IN THE HEAVIER BURSTS.
