According to the National Weather Service in Hastings, the area will get a brief relief from the cold temperatures which seem to have been in place for weeks. This will only be temporary however.
On Wednesday temperatures are expected to be in the 40s and 50s thanks to warm front which will be lifted by lee cyclogenesis over Colorado. Temperatures are expected to return to normal for February, after this a western trough, area of low pressure, will cross the area and allow more bitterly cold arctic air to drain to Nebraska starting on Friday. Highs on Friday morning could be in the low teens or 20s.
There will be a brief chance for precipitation on Thursday night into Friday morning, but thanks to the complicated flow expected to develop in the upper atmosphere, the potency of the system is uncertain. Some models have been aggressive and suggest one to three inches of snow, while others indicate nothing more than flurries. Keep an eye on the forecast as the end of the work week approaches.
Aloft in the atmosphere, flow off the Pacific Northwest remains very complex which is giving the global models trouble determining what will occur later in the week. At the surface it is expected the warm front Wednesday will drop south and a cold front will replace it. An Arctic high pressure system is expected to develop and nose south into Central Nebraska, bringing the cold temperatures which have dominated this time period.
