For those of you dreaming of a white Christmas, the most recent model data comes as a bit of an early Christmas present.
Cold Canadian Air flowing southeastward from the Upper Great Plains will meet Gulf moisture over the Midwest being forced northward. As a result, we’re looking at our first significant snow chances of the season and they’ll arrive just in time for Christmas Eve.
The first of the snow will reach our westernmost counties around 7:30 A.M. ET Sunday morning. From there, the snow will intensify and reach its peak strength between 1:00 P.M. ET and 2:00 P.M. ET that afternoon.
It appears as though the snowfall will gradually weaken and exit our easternmost counties at 9:00 P.M. ET or 10:00 P.M. ET that evening. By the time it’s all said and done, some of you will be hoping Santa leaves a snow blower under the tree for Christmas morning!
Current data places snowfall estimates for Greater Lafayette between 2” and 6” of total accumulation depending on your location. Our southernmost counties will catch a one-two punch of white stuff as tonight’s passing system may deliver them some additional snow between now and Sunday. As for Lafayette, we currently stand to receive around 4” or 5” by Christmas morning!
It’s likely that these estimates will fluctuate between now and the arrival if the storm. Weather Team 18 will continue to keep you informed of the situation as it continues to evolve.
