Last Weekends' & Upcoming Storm

Last weekend a significant winter storm struck the northern plains, especially areas of Iowa with some locations receiving heavy snow and others significant ice. Eastern Iowa saw a mix of rain, ice and some lighter snow accumulations; Ice was the significant impact there. Western Iowa saw mainly a snow event, although some light icing was also evident. Central Iowa received both snow and ice from this event, with some areas receiving both significant ice and snows! Ames received approximately .4 inches of ice accumulation before the changeover to snow, where nearly 9 inches accumulations through the weekend. Thus, significant tree damage is noted and is still occurring as the branches are being weighted down by ice/snow. Melting is going decent, but still quite a ways to go this afternoon before the next wave of storms hits' the area possibly as early as tonight.

This next system has the potential for not only significant snows, but once again the threat for ice accumulations and thunderstorms! The southeast portion of the state is in the best chance for thunderstorms and a mainly rain event, although some minor winter accumulations are possible. The western portion of the state would likely see all winter precipitation in the form of snow. The central and northeastern corner of the state is currently the one that I think needs to pay the closest attention. The low track is expected to go right along the southeast corner of the state, thus putting these areas in the best risk for ice once again. This system is going to be another hard one to forecast though as far as what type of precipitation will occur.

Another update tomorrow with final forecast on precipitation type and snowfall totals.
