A Bit Cooler Wednesday But Warming Again Late Week

Sunshine and southerly winds kicked highs to near or over 80 across Greater Nebraska today, and even near 90 in Valentine. But a cool front moving through the region overnight will bring a temporary cooldown Wednesday before summer-like warmth returns Thursday and Friday.

High pressure over the Midwest still dominates our weather, but will give way to a cool front currently located from western North Dakota into northwestern Wyoming. The front will pass through dry overnight, but will shift our winds to a cooler northerly direction late tonight. Skies will be mostly clear with lows in the 40’s with a light breeze.

As high pressure currently over Montana passes by just to our north and east tomorrow and tomorrow night, Wednesday will be mostly sunny, breezy but pleasant in the afternoon with highs peaking in the 70’s. Then Tomorrow night will be mainly clear but chilly with lows down into the 30’s.

By Thursday, the high will be centered to our east, and a southerly flow of warmer air will boost highs up toward the 80 degree mark once again with sunshine.

Friday may be the warmest day of the week with sunshine sending highs well into the 80’s. But a trough currently located over the West Coast will begin to move eastward later this week, and will gradually pass through the central and northern Plains during the weekend. This trough may be close enough to Greater Nebraska by late Friday to set of isolated showers, especially over western areas. The chance of a few showers will then be with us Saturday and into the day on Sunday, along with partly sunny skies and highs in the 70’s.
