A weak cold front and an upper-air disturbance combined to produce a wintry mix of precipitation across Greater Nebraska today, with many areas seeing some rains showers, especially across the southwest, but in the Sandhills and over Custer County some of the precipitation fell as a bit of freezing rain and snow showers. A Winter Weather Advisory is in effect for Custer County until 8pm CST for the possibility that light freezing rain could cause some slick roads, and slippery spots could develop anywhere until the precipitation shuts off around midnight. Otherwise, expect partly cloudy skies overnight with lows near 20 with a chilly northwesterly breeze.
On Thursday, the region will be under the influence of a high over Montana and Idaho, which is of Pacific origin so highs will be in the seasonable 30’s with a mixture of clouds and sun, but a brisk breeze will make it feel a bit chilly.
However, arctic air is not far away, basically situated from the Dakotas eastward. A front currently extending from the Dakotas through eastern Nebraska will move westward as a cold front during the next couple of days, so we will see temperatures trend downward into the weekend as some of the arctic air makes it into the area. Highs Friday and Saturday with sunshine will be in the 20’s to low 30’s, with lows falling into the single digits and low teens. So not bitterly cold like last weekend, but still chilly nonetheless.
By Sunday, a system developing to our west over Colorado may get close enough to produce some rain and snow showers during the afternoon and night, ending Monday morning, but right now this does not look to be significant. Highs into early next week will stay in the seasonable 30’s.
By Wednesday, a milder trend may begin as a high pressure ridge moves eastward into the Plains, and highs should get back into the 40’s.
Still no sign of a White Christmas for Greater Nebraska, but I will keep searching for any possibilities!
