Central & Northern Plains New Years Eve Storm [post 3]

Filed under: 2010 Dec 31 — Mike U @ 8:55 pm

Bitter cold airmass is on the way.  Winter Storm Warnings & Blizzard Warnings issued for portions of the High Plains, Northern & Central Plains. There isn’t a whole lot to update with this post.  A bitterly cold airmass will envelop much of the Great Plains at the onset of snow across northeastern Colorado through Nebraska and into the Dakotas.  In fact, temperatures Friday will hover around 0-5° F to go along with the moderate to heavy snow across portions of Nebraska and South Dakota.  As if that wasn’t enough, north winds will range 20 to 30 mph with gusts frequently in the 35-40 mph range from western Nebraska through much of central and eastern South Dakota.  This could turn out to be a nasty blizzard for a good portion of the northern Plains.  As for closer to home in western Kansas, the bitter airmass will be the headline with afternoon temperatures in the single digits and teens.  Accumulating snow will probably make it as far south as I-70, but unless the storm track makes an unanticipated shift to the south, much of Southwest Kansas will miss out on accumulating snow.

Figure 1 shows the surface map across the northern High Plains as of 6pm CST.

Figure 2 shows two NWS forecasts for the upcoming storm.  The top is Hays, Kansas and the bottom is Valentine, NE.  Notice the radical change in high temperature from Thursday to Friday at Hays!
