Flurries are expected to continue during the day on Tuesday without much accumulation.Wednesday: A weak upper ridge should move into the Southern Interior by Tuesday evening and continue to provide dry conditions on Wednesday. Light Westerly winds should become strong Southwesterly as the next system moves in from the Coast during the evening or overnight.Thursday: Strong Southwest winds and heavy precipitation are forecast.
