Could Christmas Eve and Christmas Day really look like this around here?
Christmas Weekend weather
Friday night: Mostly cloudy with lows in the mid 20s.
Saturday: Mostly sunny with a high just above the freezing mark.
Saturday night: Mostly cloudy with periods of snow, mainly after 2:00am. Low pressure moving our way from the west will cause snow to develop first over the southern and eastern parts of Iowa in the middle of the night — and then further into Illinois as dawn approaches. Lows in the upper teens.
Christmas Eve Day (Sunday): Mostly cloudy with periods of snow in the morning, especially before 10:00am. Snow will end first over the southern and eastern parts of Iowa and then later into West-Central Illinois. Our cold air could really make the most of fluffing up our limited amount of moisture to the tune of 1 to 3 inches of snowfall area-wide on the ground by midday Sunday — with about half our total coming from late Saturday night and half on Sunday morning as it looks to me at the moment.
The snow would be falling when temperatures will be in the upper teens and lower 20s, and this by itself will amplify even minor changes in the amount of moisture that will be available to us as to where exactly in that 1-to-3-inch range each of us ends up. This amount of snow combined with ground temperatures that finally will be cold would support snow accumulation on all surfaces including roadways — particularly on untreated roads.
Short adequate and timely plowing and salt treatment, with the colder air that will be in place, snow would accumulate even on the most frequently traveled roadways. It’s certainly worth planning your traveling and last-minute shopping around this scenario. We’d be relearning our winter driving skills on a very busy day. — If things do play out this way on Saturday night and Sunday, we would be a lock for a white Christmas this year. The sky should turn partly sunny by Sunday afternoon. Highs in the middle 20s.
Christmas Eve Night (Sunday night): Mostly clear with a low in the teens.
Christmas Day (Monday): Increasing cloudiness with perhaps some flurries or pop-up snow showers in the afternoon and evening. Highs in the 20s.
Monday night: Mostly cloudy with scattered flurries. Much colder with a low in the single digits.
Winds will be light and northerly throughout most of the weekend, so not too blustery — just plain chilly.
