NWS: IA Tornado Season started big, ended with a whimper

November 25th, 2011 by Ric Hanson

A Meteorologist with the National Weather Service in Johnston says there were 50 tornadoes in the state this year, which is just above the 30-year average of 47 tornadoes. Altogether, 16 people were injured by the events, but there were no fatalities. Craig Cogil says the season started-up rapidly in March and early April, but lost steam as the season progressed. Cogil says two significant tornado days occurred early in the season, on March 22nd over southwest to south central Iowa during the late afternoon and evening hours. The event produced 8 tornadoes over a 2-hour period, including an EF-2 in Madison County, which caused property damage to several farms and one home.  EF-2’s produced winds of 111-to 135 miles per hours.

An event on April 9th was the largest outbreak of tornadoes for one day across Iowa since May, 2004, when 20 tornadoes twisted their way across the state. The event started during the mid-evening hours when the first tornado, an EF-3 (with winds of 136-to 165-mph), hit Mapleton, in Monona County. Nearly 100 homes were destroyed and many other severly damaged in a 12-to 15-block area. The event resulted in 14 injuries and 500 residents being displaced. Several other tornadoes formed over the next several hours that day, from west central into north central Iowa, including one that tracked more than 29-miles from northern Sac through southeastern Buena Vista and western Pocahontas Counties.  It had the distinction of being 1.5-miles wide at times, and produced numerous “Satellite” tornadoes, which tracked around the main tornado. One of the satellites was an EF-4 (winds from 166- to 200-mph). It destroyed a farmstead and tossed a combine nearly 300-yards.

Two significant tornado events occurred in May, including two on May 11th that hit the town of Lenox within a span of 5-minutes. Both tornadoes were rated as EF-1’s, producing winds of 86 to 110-miles per hour. Both tornadoes caused extensive roof and tree damage. The other tornado event in May was in eastern Iowa’s Howard County.

The remainder of the season saw 10 more tornadoes occurr on six different days. The most occurred on June 20th, when four twisters were observed. The last tornado of the season was on July 11th. It caused extensive damage in portions of central and eastern Iowa. The fact the last tornado was confirmed on that date marked the earliest cessation of tornadic activity in the state since reliable records started in 1980, beating the previous earliest cessation record set on July 24, 1992.

DES MOINES, Iowa (AP) – Authorities say snow totals ranging from 2 to 6 inches have been reported in central Iowa. A National Weather Service winter weather advisory says up to 7 inches is expected in some areas before the storms leave the area by midmorning Wednesday. Service meteorologist Darren Snively says that roads will be slick, so people will have to remember how to drive safely in winter conditions. No weather-related road closures have been reported, although several highways in the north-south middle third of the state were covered with snow or a slushy mixture, and some power outages were reported.

October ends as one of Iowa’s driest Octobers, and it was warmer, too

News, Weather

November 1st, 2011 by Ric Hanson

Humidifiers have been running almost non-stop for weeks as one of Iowa’s driest Octobers in more than 20 years is now over. State climatologist Harry Hillaker says the month that just ended saw very little rainfall, though it wasn’t a record-breaker. “The driest one is in a class all by itself, way back in October of 1952,” Hillaker says. “Most of the state had no rain what-so-ever and the statewide average was just 2/100ths of an inch for the month. That’s our driest calendar month of any month for the year, not just for October.”

Here in Atlantic, we received just .21” of rain during the month. The normal average is 2.54-inches. While official State numbers are still being tabulated, this October saw a statewide average between three-quarters of an inch and eight-tenths of an inch of rain, which will rank it around the 10th driest Iowa October on record. It was the driest October since 1988 when we only averaged two-thirds of an inch of rain statewide. Hillaker say the just-ended month was also warmer than usual.

“The month is going to average out about three-degrees warmer than normal,” he says. “We actually got off to a rather cold start. We had an unusually cold September and the first couple of days in October were well below normal as well. A little bit of cold weather was mixed in, especially the last week or two, but most days were above normal.” As for the month ahead, November may follow suit, at least as far as warmth.

“November, historically when we’re in a La Nina weather pattern as we are right now, has quite strong odds of being warmer than normal and just a teeny tendency to be on the dry side of normal as well,” Hillaker says. Based on the forecast though, he says Iowa may see rain showers as soon as tomorrow (Wednesday) with an even-larger storm front possibly moving over the state this weekend.

The average high for October in Atlantic, was 68.5-degrees, which was slightly warmer than the normal average of 65.7. The average low was 35.9, which was slightly cooler than the normal average of 38.1.

Burn Ban in effect for Cass County, IA from 3-p.m. Oct. 7th until further notice

October 7th, 2011 by Ric Hanson

Dry and windy conditions and little chance of precipitation have prompted officials in Cass County to issue a Burn Ban, which will remain in effect until further notice. The ban was instituted at 3-p.m. today (Friday, Oct. 7th), by Cass County Emergency Management Coordinator Mike Kennon, after he submitted a request which was approved by the State Fire Marshal’s Office. The ban means opening burning is prohibited until the Fire Marshal deems conditions in the county are such that open burning no longer constitutes a danger to life or property.

Burn bans are already in place in several northwestern and Central Iowa Counties. Cass County is the first in southwest and western Iowa to institute the ban. Just before the ban went into effect, a field fire was reported northwest of Atlantic this (Friday) afternoon. No buildings were in danger from the flames. Crews from Atlantic, Marne and Elk Horn were working the scene just before 3-p.m.
