I won’t be able to update during the day today, but here is what the latest is…
A storm system late on Christmas Day will likely organize as a four-conrers low, a term that some weather enthusiasts are familiar with as it relates to Front Range snow. After a mild start to Christmas Day a cold front should sweep down the Front Range during the afternoon. Snow is likely to develop in the mid afternoon to early evening period. With falling temperatures and the possibility of some brief moderate to heavy snowfall rates, road conditions may deteriorate rapidly near or after nightfall on Christmas (could be during the afternoon in Cheyenne).
Expect 3-6 inches through much of the area by midday Friday, and probably 5-8 inches in some places in and very close to the foothills and Palmer Divide. Light snow and clouds may linger into Saturday morning. Accumulation should be lighter out on the high plains, but blowing snow will likely be a hazard there. To the west, winter travel conditions are likely to develop on Christmas Day, especially at the passes.
It still looks like a multi-day cold wave next week, possibly beginning Sunday night or early Monday. We could see some days with high temperatures below 20 and lows below zero.
