Not So Light Snow Tonight & Tomorrow

Good Morning!

I'm sitting here looking at the forecast that I wrote maybe seven hours ago, and it has already changed!  I said that an upper impulse would work through with some flurries or light snow.  Latest forecast data has intensified the system coming through here tonight such that a Winter Weather Advisory has now been posted by the National Weather Service...Calhoun, Ingham, Eaton, Clinton, Jackson - you're in play for this one.

I warned you that Old Man Winter wasn't happy!  Based on this, clearly the forecast needs to be changed.

Here's the revised look:

Today - becoming cloudy, snow developing this afternoon from west to east, high 9.  Wind WNW increasing to 10-20 MPH by nightfall.  Wind chills near or below zero.

Tonight - snow, intense at times, accumulations 2-4 inches total by late Thursday morning, heavier as you move west.  Low 0.  Wind chills as low as -20.  Wind turning more southerly and increasing to 15-25 MPH will cause blowing snow and travel issues.

Thursday - snow tapering off around lunch time, continued bitterly cold.  High 9.  Wind SW 7-14 MPH, wind chills as low as -10.

I'll have more for you later this morning!
