After this weekend’s bitter cold, temperatures this afternoon have become milder, and the weather this week will be rather tranquil with some sunshine and highs generally in the 30’s to near 40, and lows near zero early then in the teens later in the week. But a bitter blast with snow appears to be looming for later in the weekend through next week, so this week will be a good time to put away any outside holiday decorations before that occurs.
In general, high pressure will dominate the weather across Greater Nebraska this week, as a couple clipper-type systems move southeastward out of Canada and toward the Great Lakes, pushing weak back-door fronts through the region. The first of these fronts will come through tonight, with mostly clear skies and lows dropping to near zero. The air-mass behind this front will probably keep highs Tuesday a couple of degrees colder than today, but highs with sunshine should still rise to near freezing. However, watch for icy spots tomorrow morning, and the next several mornings as melting of any snow will occur during the day, but then refreeze at night.
Wednesday through Friday, skies will be mostly sunny during the day with highs in the 30’s to perhaps lower 40’s, and lows in the single digits rising to the teens late week with a few clouds at night.
By Saturday, an upper-level low that will be sitting off the California Coast all this week will begin to move eastward. At the same time, another upper-low will drop into the Rockies. The Rockies low will continue to drop southward, and by Sunday should be located over the southern Rockies and Plains. As this system drops south, it will pull bitterly cold arctic air with it that will begin to invade the area during Sunday. In addition, a surface low should develop somewhere from the Front Range to the Southern Plains and then begin to move eastward to our south. As this system evolves, an accumulating snow is possible across Greater Nebraska, possibly beginning as early as Saturday evening, but mainly Sunday into the day on Monday. Also, the cold will rival, and possibly exceed the cold that we just experienced late last week and this weekend, except this cold blast looks to be a long lasting one, perhaps one that will last through all of next week and beyond.
So stay tuned to News 2 all week long for the latest on this new blast of winter.
