Weather Flash: First Measurable Snow?

Rexburg Snow

Last week we plunged from late summer to mid-autumn. Now get ready to dive just as abruptly into early winter. A strong cold front will pass through early Wednesday, decreasing Tuesday’s high temp of 63 by about 25 degrees and possibly leaving 1-2 inches of snow. Most of that snow would fall Wednesday morning through mid-afternoon. And after the cold front, lows the next three nights are forecasted to be 14, 15, & 19 degrees.
