It would seem as if nature is trying to make amends for the unusually cool, damp autumn that we’ve had to endure. Apology accepted. As an upper level ridge builds in the wave of warmer air is truely extensive with climbing temperatures from the prairie provinces of Canada all the way to Texas.
To lend some perspective, temperatures in the teens are possible this time of year as far south as central North Dakota, but during the next couple of days they will be warming into the 60s with 50s across the border into Canada. Certainly unusual.
So what is this ‘high pressure ridge’ that is responsible for this turnaround? (more…)

The only sign of it’s influence was the clouds of this morning, but to our north is an Alberta Clipper that will track through the Dakotas to eastern Minnesota by midnight tonight. The air at the surface is very dry so we did not realize any precipitation from those clouds because it evaported before it hit the ground. So what is a “clipper”? (more…)

Impressive snowfall totals along the Wyoming/Nebraksa border with 6-10″ on the ground by early evening and nearly a foot of snow from Alliance to Chadron. Couple the snowfall with 20 to 30 mph winds and it’s no wonder Interstate 80 was closed between Laramie and Cheyenne.
The storm is rounding the the bend near the 4 Corners region and turning northeast through Colorado to northern Nebraska before departing into Minnesota. The Tri-Cities will stay on the warm side of the storm as will central and eastern parts of the state. Custer County could see a little accumulating snow mainly in the western areas in the 1-3 ” range.
The faucet has now been turned on with rainfall now streaming out of Kansas northward, with heavier rain emanating from Phillips County into Harlan with tenth of an inch rainfall rates. Most of the rain be west of the Tri-Cities but gradually become more widespread eastward through the night with intervals of rain through the day tomorrow.

Band of heavier snow continues east of highway 281 to near highway 81. An inch or two of accumulation possible with this. Most other locations will ony pick up a trace. Snow will be ending from east to west and complete be through our area by dawn.
Lingering morning clouds break up and clear out the rest of the afternoon

We will continue to fill the rain gauges throughout the night with 1-2″ amounts still a possibility. The primary questions concern snowfall and this is where it really gets interesting. The amount of snow, or even whether it snows at all, may come down to as little as three degrees of accuracy.
I think we will see some snow, the amounts remain somewhat of a puzzle. The track of the storm and the amount of moisture available to it is working in favor of appreciable snow. Fighting against that is the warmth of the ground which allows for some melting, and how warm the temperatures will be in the last 100 feet to the surface. Forecast models have us in the mid 30s, holding steady or gradually falling through the afternoon. If that holds we could be seeing only rain, or a rain snow mix. If the dynamics can squeeze out heavier snow, the lower levels could cool by its own merit enabling more snow to accumulate. We call that dynamic cooling.
At this point I’m hesitant to go too heavy on snow amounts for the Tri-Cities. Southwest Nebraska will see the most (3-6″ possible) but for us we could be splitting hairs between 3″in Kearney to nothing in Hastings. At most 1 think 1 to 2″ seems reasonable on the high end.
See how fun the weather is in these parts!

Our rainy forecast remains on track. An upper level storm system out of the southwest still is going to position itself over Kansas in and area conducive for heavy amounts of rain for our area. One thing that we will be monitoring closely is the slow movement of the storm and the potential for accumulating snow farther east than anticipated. Slower movement and dynamic cooling could allow more cold air to entrain into the storm causing a snow transition over a broader area. At present the only watch is for extreme southwest Nebraska effective tomorrow afternoon. We’ll see if that watch might be expanded.
