Record Cold

November 17, 2014

It is cold across the nation. The only place “warm” is south Florida. Here are the temperatures as of 7 PM from the Oklahoma Mesonet.

3

The jet stream is in a large “U” shape or trough and this is allowing the cold air across the nation.

4

We are dealing with the coldest air of the season so far and it is cold enough to break record cold highs and record lows for November. The first graphic is from today (Nov 17). A record cold high was set in Waterloo. The NWS does not have any record data for Cedar Rapids or Iowa City.

Blog Graphic 3

Now tonight temperatures are expected to drop to near zero by morning with wind chills of 10 to 20 below zero. The forecast lows are all new record lows for Tuesday (Nov 18)

Blog Graphic 1

Starting out is a deep “temperature hole” it will be hard to get out. High temperatures again will be in the teens with a better chance of both Waterloo and Dubuque breaking the record cold highs for Tuesday (Nov 18)

Blog Graphic 2

Every state in the lower 48 will have a low temperature below freezing Tuesday morning.

First Snow Area Wide

November 13, 2014

1
Clouds will slowly clear tonight with temperatures in some locations dropping into the single digits by morning — and one to two inches of snow is expected on Saturday.

Sunshine returns Friday, but it doesn’t help warm the temperatures up. Afternoon highs only reach the 20s again.

Clouds increase late Friday night.

Light snow develops around midday Saturday, and continues through the afternoon and night before ending around sunrise Sunday.

Snow accumulations area wide will be 1-2″ with an isolated 3″ reports possible.

This would be our first accumulating snow for all of eastern Iowa. The wind will be light with this snow, so blowing snow will not be a concern.
