The cold is here to stay for the rest of the work week. According to the National Weather Service in Hastings a strong disturbance will force a surface low pressure area to move across Kansas and Oklahoma, this will be followed by another cold front, helped along by strong winds from the north. This disturbance at the moment looks to stand a chance of dropping some accumulating snow. There are still questions of where the location of the surface low will be and the heaviest snowfall.
The potential for snow will begin Wednesday morning in the north and transition southwest during the daytime hours. The best chance for accumulation will be Wednesday late afternoon into the evening hours. With the information available at the moment, one to three inches of snow is possible for much of south central Nebraska.
There is a slight concern for freezing drizzle as this system moves in, especially for areas south of I-80. Ice is not expected to accumulate at this time, but there could be a light glaze which could impact travel during the afternoon and evening Wednesday.
Needless to say, temperatures will drop Wednesday night. Combined with strong northerly winds overnight, it will cause below zero wind chill temperatures across the region for Thursday morning. There is the possibility for wind chill values to drop as low as 10 to 20 degrees below zero. With the cold air in place there will be precious little recovery during the daytime hours, so expect the cold to linger throughout Thursday.
Friday is expected to remain cold with low wind chill temperatures, but the coldest temperatures will be in the eastern half of the NWS warning area.
The pattern of a cold work week and warmer weekend looks to hold. The weekend looks to be warmer with southerly flow warming temperatures up. There is a disturbance which could bring more precipitation chances on Sunday.
