The National Weather Service office in Cheyenne has released the following special statement:

Location Confidence: There is Low confidence at this time where the exact snow bands are going to set up. Run to run model consistency has trended the heavy snow area further south from previous days and now has the heaviest snow across the I-80 Corridor (see attached 6 and 8- inch Probability Graphics).

Timing: There is Moderate confidence with the timing of this storm and when we'll see impacts. Here are the time ranges of when we expect the worst impacts:
•Wednesday night through Thursday night for areas west of the Laramie Range including Rawlins, Laramie, Saratoga and Interstate 80 west of Laramie.
•Thursday Morning through Friday morning for southeast Wyoming along and east of the Laramie Range including Cheyenne, Wheatland, Douglas, Torrington and Interstate 80 from the Summit to the Nebraska state line.
•Thursday afternoon through Friday morning for most of western Nebraska including Sidney, Scottsbluff, Chadron, Kimball, and Interstate 80 from the Wyoming state line.

What To Expect

•Winds: There is Moderate confidence that winds will play a factor with this event. Some guidance is showing northeast winds of 20 to 30 MPH sustained with gusts approaching 35 MPH for areas west of the Laramie Range. For the areas east of I-25 on Thursday, expect north to northeast winds 15 to 20 MPH with gusts to 30MPH. Visibilities may be reduced to less than one-half mile in snow and blowing snow, especially west of the Laramie Range.

•Snow Accumulations: 12-20" in the Snowy & Sierra Madre mountains Wednesday afternoon through Thursday night. 5-9" across the lower elevations of Carbon and Albany County by Friday morning. 10-12" in the Laramie Range. 5-9" areas east of the Laramie Range, with 3" to 6" across the northern Nebraska Panhandle and 2-5 inches across the southern half of the Nebraska Panhandle. Again, these snow amounts may change depending on the exact track of the upper low and final location of the surface cold front.
