Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 128 PM EST Mon Mar 02 2015 Valid 00Z Tue Mar 03 2015 - 00Z Thu Mar 05 2015 ...Heavy snow likely over parts of the Central Rockies... ...Temperatures will become 15 to 25 degrees below average over the northern and central Plains by the middle of the week... The models show a storm system crossing the Great Basin tonight through Tuesday, producing moderate to heavy mountains snows in CO and adjacent WY with lower elevation showers across the southwest. One to two feet of snow is likely over preferred upslope regions in the mountains. The next frontal system will move out of Canada and across the northern Plains. Snow will break out in the upper Mississippi Valley and Great Lakes, becoming mixed with sleet and freezing in the mid Mississippi Valley. Further south, rain showers are likely in the lower Mississippi Valley to the Ohio Valley. Tuesday night into Wednesday, the storm progresses quickly across the Great Lakes into New York and New England. More snow is expected in the northeast, with another mixed precipitation event in the Mid Atlantic Tuesday. The trailing front slows down in the Tennessee Valley to the southern Plains. Waves of low pressure develop along this front on Wednesday, resulting in another mixed precipitation event. Rain near the front transitions to sleet, freezing rain and then snow across much of the southern Plains to the lower Ohio Valley, central Appalachians and mid Atlantic. Several inches of snow are possible. Showers will develop south of the front across the lower Mississippi Valley to the Tennessee Valley Wednesday. Northwest wind usher in the next blast of arctic air in the northern Plains Tuesday, spreading south across the central and southern Plains to the upper Mississippi Valley Wed. Temperatures are forecast to be 15 to 25 degrees below normal. Temperatures are expected to be several degrees above normal along the west coast and in the southeast on Wednesday.
