April 3rd, 2012 by Ric Hanson

DES MOINES, Iowa (AP) – The National Weather Service says the lack of winter weather and some record high temperatures helped make March the warmest on record in Iowa. The service says there were several date records and entire weeks of record warmth.

Some examples:  The high of 84 in Des Moines on March 16 broke the 1930 record of 77. The high of 82 in Waterloo on March 17 broke the 2003 record of 78; The average temperature of 66.6 degrees in Waterloo from March 16 through March 22 was nearly 30 degrees above normal for that span; For the month in Des Moines, the average temperature of 55.7 broke the 1910 record of 51.5; For the month in Dubuque, the average temperature of 50.2 degrees broke the 1910 record of 47.7 degrees.

In Atlantic, the average High for March 2012 was 67-degrees, or 22-degrees above the normal average High of 45. The average Low last month was 39, which was 14-degrees warmer than normal.  Rainfall for the month was 1.91-inches, which was nearly four-tenths of an inch below normal.

The month of April started out with a near record high in Atlantic. On Sunday, we topped out at 86 degrees, which was just 1 degree shy of tying the record for that date. On Monday, we broke our record high of 85 set in 1981, when we hit 88-degrees.

Feds: ‘Meterological March madness’ mostly random

News, Weather

April 2nd, 2012 by Ric Hanson

WASHINGTON (AP) – A quick federal analysis blames most of the record warm March weather that gripped two-thirds of the country on freak chance, a nice southerly wind and only a tiny part man-made global warming. For much of March, record temperatures hit as high as 35 degrees above normal and averaged about 18 degrees warmer than usual. 

In Atlantic, the average High for March 2012 was 67-degrees, or 22-degrees above the normal average High of 45. The average Low last month was 39, which was 14-degrees warmer than normal.  Rainfall for the month was 1.91-inches, which was nearly four-tenths of an inch below normal.

The National Oceanic and Atmospheric Administration analyzed the causes and chances of what it nicknamed “meteorological March madness.”  Meteorologist Martin Hoerling (HURL-ing) said the main cause was a persistent warm wind sending toasty air north from the Gulf of Mexico. He said blame for a version of this heat wave is about five parts randomness to one part global warming. Climate change alone can only account for about 2 degrees of the added heat.

Severe Weather Awareness week begins in Iowa

News, Weather

April 2nd, 2012 by Ric Hanson

Today (Monday) marks the beginning of Severe Weather Awareness Week in the state. National Weather Service meteorologist, Jeff Johnson says there weren’t many tornadoes in 2011. “In Iowa, we had what I would call a pretty normal year. We had 51 tornadoes, we average 47, that’s pretty close to normal,” Johnson says. “What was interesting about last year though, was that most of those tornadoes occurred on or before April ninth, so many of those tornadoes were early in the year in 2011.”

Johnson says it is too early to tell what type of year 2012 will bring for severe weather.  “A lot of people have been talking about the recent warm weather and if there is a correlation between that and active severe weather, and there really isn’t much of a correlation between an active severe weather season and the early spring warmth,” Johnson says. He says there’s also not much of a correlation between a warm summer after a warm spring. The National Weather Service has special theme days all week to teach Iowans the dangers of severe weather.

Johnson says the theme for today is flash flooding. “Which is the number one thunderstorm-related killer in the United States from weather, it’s not tornadoes, it’s actual flash flooding,” according to Johnson. He says Tuesday will talk about how to get a warning, Wednesday’s theme centers on tornadoes and there will be a statewide tornado drill, and finally, family preparedness is the theme on Friday.

Johnson describes the tornado drill scheduled for 10 a-m Wednesday morning: He says they will come out with a tornado watch at 10 and that will last for about an hour. “And then at about 10:15, give or take a few minutes, we will issue a tornado warning and it will go off over your weather radios, it will go out over the emergency alert system to the radio stations and many, many communities will be testing their siren systems at the same time,” Johnson says. He says this will be a good time for businesses to test their evacuation plans. You can find out more information on severe weather in Iowa at www.weather.gov.
