National Weatherperson’s Day

If you haven’t heard already, February 5th is National Weather Person’s Day.

john_jeffriesThis “holiday” is to commemorate the birth of John Jeffries in 1744.  Jeffries is said to be one of the first people to take weather observations beginning in 1774.  Twice daily, National Weather Service offices across the United States send up a weather balloon with a radiosonde that measure different weather parameters at different layers in the atmosphere.  Jeffries took the first weather balloon observation in 1784.

From the National Weather Service: “National Weatherperson’s Day was created to recognize the men and women who collectively provide Americans with the very best weather, water, and climate forecasts and warning services of any nation in the world.”

All of us with the KWWL Storm Track 7 weather team appreciate you tuning in for your eastern Iowa forecasts each and every day.

Heavy Snow in 1985


A winter storm struck Iowa from late on November 29th through December 1st producing heavy snow across much of the state. A wide swath from southwest to northeast received 8 or more inches with many stations from around Guthrie Center east northeast to Waukon and Dubuque recording a foot or more of snow. In northeastern Iowa Decorah, Dorchester, and Waukon all set their single-day snowfall records with Dorchester reporting a remarkable 18.0 inches of snow in just 24 hours ending on the morning of the 2nd. Other reported three-day snowfall amounts included 13.5 inches at Charles City and Waterloo, 14.0 inches at Independence and Waukon, 14.8 inches at Decorah, 16.0 inches at Tripoli, 16.5 inches at Oelwein, 17.0 inches at Fayette, 18.6 inches at Dubuque, and 19.0 inches at Elkader and Iowa Falls. Winds gusted to 40 to 50 mph by December 1st, combining with bitterly cold air to produce wind chills of -40 to -60 and resulting in blowing and drifting of snow that brought travel to a standstill across much of Iowa.

October 29, 1925

On this date in 1925: Unseasonably bitter cold weather set in after a pair of early winter storms. The temperature plummeted all the way down to -15 F at Inwood setting the all-time Iowa October record. At Waterloo, the month would finish as the coldest October on record with an average temperature of only 40.5 F. The map attached is from October 29, 1925 and shows a large area of high pressure across the middle of the country.

Tornadoes in January…in Iowa

From the NWS:

On This Day in Iowa Weather History

January 24

1967: An unprecedented January tornado outbreak struck eastern and southeastern Iowa and portions of Missouri, Illinois, and Wisconsin. There were at least 13 tornadoes in Iowa with many of these producing significant F2 or F3 damage. Two tornadoes struck Lee County resulting in 10 injuries, and one of those tornadoes produced F3 damage and killed a young child just west of Fort Madison. Another tornado produced F4 damage just across the border in northeastern Missouri before entering Davis County. A cold front moved through the state later that night and on the 26th snow fell across about the southern half of Iowa with snowfall amounts ranging up to 13.5 inches at Burlington, less than two days after tornadoes had touched down in the same area. To put the extremely unusual nature of this outbreak into perspective, this is the only date in January on which a tornado has ever been recorded in Iowa and only one has ever been recorded in February.

Weather Extra Bar

On this day in 1980, Waterloo and Fort Dodge reached 100 degrees. This is the earliest date in Iowa to reach 100 degrees. What makes this more interesting is just 8 days earlier (on the 14th) 6” of snow fell across eastern and southeast Iowa.

Tonight…The sky will be mostly clear through the evening. There are two space station flyovers this evening:

Clouds will increase from the west tonight as the wind diminishes.
Apr 22 Vis Sat

Wednesday/Wednesday Night… Scattered showers and an isolated storm or two are possible Wednesday with the best chance in the afternoon and overnight.

Thursday…Low pressure will track across Iowa with showers and thunderstorms. As I type this it doesn’t look appear severe weather will be a concern. Don’t worry we will still be tracking the storm as it moves east to see if there are any changes to the severe weather risk. Here is the rain potential for Wednesday and Thursday.

Apr 22 Rain

Friday/Saturday…These days will be dry and a bit windy…especially Friday.

Sunday-Tuesday…Low pressure will develop across the middle of the country and bring a chance of showers to eastern Iowa. We will be on the north side of the low and experience a gusty east wind during these days. In addition to the windy conditions, it will be colder. High temperatures will struggle to reach 50 degrees.
