World Record High Dew Point

Our humidity level will go up this weekend as dew points climb above 70°. The highest dew points we ever see here in Iowa are in the low 80s…now that is humid. I have one better. On July 8, 2003, Dhahran, Eastern Province, Saudi Arabia the dew point soared to 95°. Yes 95°. That is a world record high dew point. Here is the observation at 1 pm that day.

Dhahran is located along the coast of the Persian Gulf.

So when we deal with the warmer temperatures and higher humidity Sunday/Monday…just remember it can always be worse.

Coldest Iowa Temperature

1

From the NWS:

On This Day in Iowa Weather History

February 3

1996: Extremely cold temperatures that began on January 31st persisted into early February with wind chills as low as -79 F at Mason City on the morning of the 2nd and high temperatures of -20 F recorded at Elkader and Oelwein that afternoon. Temperatures finally bottomed out on the 3rd with all-time record lows occurring across the region, including -47 F at the Osborne Conservation Center southwest of Elkader which tied the all-time Iowa low temperature record set in 1912. All-time records were broken on the morning of the 3rd at about 20 percent of the official observing sites around Iowa including Albia with a low of -31 F, Muscatine and Toledo at -34 F, Belle Plaine and Indianola at -35 F, Fayette at -40 F, and Chariton where the reading of -38 F broke their all-time record which was set just three days earlier on January 31st. Over the four days from January 31st through February 3rd the statewide average temperature was -13.5 F making it the second-coldest four day stretch on record in the state. Des Moines reported an unprecedented 132 consecutive hours below zero from January 30th into February 4th.

Iowa Record Low Temp

Temperatures were in the teens below zero this morning. It doesn’t come close to the record low temperature for Iowa. On this date in 1912 Washta (east of Sioux City) had 47 below zero. I hope we don’t break this record anytime soon.

Record Cold

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.
