Tuesday will feature the coldest temperatures of the week, with highs in the teens F and a lull in the incremental snowfall. Temperatures will warm, and chances for light snow accumulation will return in the second half of the week.
A few snowflakes are falling as I write this update on Friday afternoon. By Saturday morning, 3-4 inches should accumulate. Temperatures will be noticeably colder on Saturday when winds will be blowing from the north 10-15 mph with high temperatures in the teens F.
The sun should peak through the clouds briefly Saturday afternoon. Temperatures will warm into the 20s F for Sunday with strong winds from the west blowing 30-40 mph. A cold front will cross over the area early Monday bringing some of the coldest air yet, more snowfall (maybe 4-6 inches), and lighter winds.
Looking ahead in the weather models - there are no major storms lined up, but there is also no major ridge of high pressure forecasted. At the moment, it seems the pattern will be a series of disturbances and troughs that should bring a few inches of snow here and there which can add up surprisingly fast. Fingers crossed!
This morning (Wednesday) temperatures are teens to 20s F and wind is out of the southwest and northwest at 10-20 mph with gusts of 30-45 mph.

For the second half of this week daytime temperatures will reach high 20s to mid-30s F with lows in the teens and low 20s F. Today and tomorrow winds will be out of the southwest at 15-20 mph with gusts of 30-40 mph. Skies will be mostly clear until the next measurable round of snowfall arrives late Friday or Saturday, with some light snowfall in the southern part of our area tonight and tomorrow.
Mountain temperatures on Wednesday morning are in the single digits to teens F, with 10-25 mph winds blowing from the west to the north.
