It’s been a pretty uneventful winter thus far, though that’s not that surprising considering the winter season only officially began with this morning. The annual Winter Solstice occurred this morning at 11:28 A.M. ET ushering in the year’s fourth season and shortest day.
Today marks our sixth straight day of above average temperatures here in Lafayette and while it appears as though we’ll see a 7th, don’t expect the mild conditions to stick around much longer.
I’m tracking a one-two punch of low pressure and a secondary cold front expected to not only restore our winter-like temperatures, but keep afternoon highs well below average for a prolonged period.
After receiving some initial rainfall Friday, current model data suggests that we’ll see a period of wet snowfall surging northward on the back edge of a passing low early Saturday morning.
Sustained rainfall will begin to change over into a wet snow beginning around 1:00 A.M .ET or 2:00 A.M .ET Saturday morning before exiting east around 8:00 A.M. ET.
While the latest data indicates that portions of the region may see minor accumulations, it’s unlikely that any of that snowfall will be left at the end of the day; temperatures are expected to reach the mid to upper 30s that afternoon.
There’s at least some data now indicating that we may see another round of light snowfall on Sunday as well, but there’s not a whole lot of agreement between models currently.
While one model says we’ll see an additional 1.5” in some spots that day, there’s another that depicts little more than a flurry or two reaching the surface that day. At this time I’ll keep the chance of light snow in the forecast, but don’t place any bets on a white Christmas quite yet.
Christmas, on the other hand, looks like it will remain dry. Unfortunately, it won’t be too mild for the holiday. Expect a high temperature of just 26° in Lafayette on the 25th; if that forecast holds, it will be our coldest Christmas since 2004 when we only reached 21° on the holiday.
