Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – November 7th, 2018

Forecast discussion:

Northwest flow continues as the arctic begins to dump blobs of cold air into the U.S. Midwest. We are on the western edge of this cold-front-train. For most of the rest of the week, we'll be to the north of the frontal zone and highs will remain quite chilly (40's F - Figure 1).

Our next storm pulls past us tonight to Thursday AM (Figure 2). There are chances of snow mixed with the rain, but the significant snows will be out on the plains. Figure 3 shows where blizzard like conditions will occur over the next few days. Figure 4 shows that it is not expected to push this far west at this time. Oh well, snow will come... someday!

The longer range forecast:

That someday may be this weekend. We remain pretty cold overall with a more significant storm on the horizon for Saturday PM and Sunday AM, but we'll handle that after the current storm manifests.
