Our weather scenario appears to be playing out as expected.
Snow will develop this evening, and perhaps even become heavy for a couple of hours. We could easily pick up an inch or a little more. Once this band of snow passes through, precipitation will lighten up a bit, and then freezing rain will move in late at night.
As warmer air pushes northward, the freezing rain will transition to regular rain from south to north. Since areas north of I-69 will be the last to change over from snow, your snow accumulation will probably be closer to two inches.
Accordingly, the National Weather Service has issued a Winter Weather Advisory from 10:00 p.m. Tuesday until noon Wednesday north of I-69, and until 9:00 a.m. south of I-69.
Temperatures tonight will initially drop into the mid 20s (-4 degrees Celsius), and then rise to around 30 degrees (-1 degrees Celsius) by dawn Wednesday. Highs Wednesday should reach 40 degrees or a little above (5 degrees Celsius).
Rain should taper off by late afternoon Wednesday, and we’ll then be dry through New Year’s Eve. Lows Wednesday night in the mid 20s (-4 degrees Celsius), highs Thursday in the mid 30s (1 degree Celsius), and lows Thursday night in the mid 20s (-4 degrees Celsius).
The New Year’s Storm
Today’s computer models have slowed the arrival time of the New Year’s storm. It now appears that we’ll start Friday morning dry, freezing rain will develop by late morning, which will then change to regular rain, which will continue into Friday night. Temperatures Friday should eventually reach around 40 degrees (4 degrees Celsius).
What is a winter weather advisory?
A Winter Weather Advisory will be issued for any amount of freezing rain, or when 2 to 4 inches of snow (alone or in combination with sleet and freezing rain), is expected to cause a significant inconvenience, but not serious enough to warrant a warning.
