'17-'18 Winter Storm #16
Posted: 18 Feb 2018 01:17 PM, Views: 728
A quick moving system brought a brief downpour of snowfall on Saturday which only amounted to an inch or two over the state, but created for some travel impacts due to the intense snowfall rate. Most of this snowfall melted later on Saturday as temperatures warmed nicely to finish the day. Our next storm system will be here tonight.
