Iowa vs. Alaska

The maps below show the temperatures at 8 PM CST. It is colder in Iowa than it is in much of Alaska. Typically when Alaska is cold we are warm and the opposite is true as well.

Here is a look at the upper air pattern.

More Mild Weather….Arctic Air this Weekend

UPDATED at 4:00 PM

Tonight: Partly to mostly cloudy. Low: 8-11. Wind: SW 5-10 mph.

Tuesday: Mostly sunny. High: 27-32. Wind: SW 10-15 mph.

Tuesday Night: Increasing clouds and breezy. Low: 17-20. Wind: SW 10-20 mph.

Wednesday: Mostly cloudy. High: near 40.

Thursday: Mostly sunny. High: upper 20s.

Friday: Mostly sunny. High: near 40.

Saturday: Partly cloudy and windy (NW 15-25 mph). High: upper 30s.

Sunday: Party cloudy. High: low 20s.

Monday: Partly cloudy and cold. High: low teens.

The evening sky will be mostly clear, but after midnight some clouds will move overhead. No precipitation expected from any of the clouds.

Tuesday will have lots of sunshine with high temperatures a few degrees warmer than Monday. Clouds will increase Tuesday night as the wind increases from the southwest. The low temperatures will not be as cold as a result.

Ahead of a warm front, Tuesday morning, there is a chance of a few flurries in far northeast Iowa and southwest Wisconsin. The rest of the day will be dry and warmer. Here is the HPC forecast map for Wednesday morning.

The warm front will track east through the state during the day. It will push afternoon highs into the upper 30s. A cold front will move south of the Iowa Thursday morning with colder temperatures (highs upper 20s). The colder air doesn’t last long because the cold front turns into a warm front and moves north of Iowa Friday morning. The result will be highs again in the upper 30s Friday and Saturday.

There has been a lot of very cold air across Canada just waiting to move south and this weekend it will be on the move. A cold front is forecast to move south across Iowa Saturday morning.  Here is the HPC forecast position of the cold front Sunday morning.

The cold front will be ushering in a cold and large area of high pressure from Canada. High temperatures Monday will only be in the low teens. There is a potential some locations will be in the single digits for highs Monday.

Other than the warm weather being replaced by the arctic weather in the next seven days it will remain dry. Here is the amount of moisture forecast from Monday evening through Saturday evening.

Looking at the CPC 8-14 day outlook for January 22-28 temperatures are forecast to remain below normal with below normal precipitation in Iowa.

January 14

From NWS
: An ice storm struck southern Iowa on January 13-14 with an observer in Keokuk recording 1.93 inches of rain in 24 hours and writing that the rain “froze on trees, wires and walks as it fell, covering them with a heavy coat of ice, crippling all electric service, and doing a vast amount of damage to trees, breaking off large limbs with the weight of the ice.” In Adair County it was noted that “the ice was formed over an inch thick on wires and trees, and the telephone, telegraph and light companies were greatly damaged. The streets were impassible all over town.” Significant ice and sleet damage was also reported at Keosauqua and Stockport.

 This Day in National/World Weather History …
 14 January 1882 → Southern California experienced its greatest snowfall on record. San Bernardino reported 15 inches of snow, while even San Diego reported a trace.
 14 January 1932 → In Lexington, TN a tornado struck a house killing at least ten members of a family.
 14 January 1972 → The U.S. record 24-hour temperature rise occurred at Loma, MT when the mercury rocketed 103 degrees from -54F to 49F thanks to a powerful chinook.
