Ice reports from the National Weather Service (1/16/17)

Weather

January 16th, 2017 by Ric Hanson

The National Weather Service is updating the amount of ice that has accumulated at various communities across the state this morning. Ice generally ranged from .1″ (one-tenth of an inch) to .2″ across parts of west-central and southwest Iowa, to as much as .3″ in eastern Iowa, near Cedar Falls.  An additional .1″ to .25″ can be expected across the listening area before the precipitation ends early Tuesday morning.

Atlantic, .1″ (KJAN)

Audubon (1 mile S/SE), .1″

Carroll, .1″

Lorimor, .2″

Mt. Ayr, .25″

The ice storm will continue through much of the day today with the bulk of the freezing rain accrual occurring through around midday. An additional tenth to quarter inch of ice is likely by this afternoon across much of central Iowa. Above freezing temperatures at the surface look to creep into southern Iowa later this morning and mitigate the additional ice amounts. By tonight, light wintry mix is anticipated on the backside of the low pressure system over northern Iowa where light snow/sleet accumulations are possible. Mainly light freezing rain or freezing drizzle can be expected elsewhere with an additional glaze of ice possible. Once this system clears the state late tonight, above normal temperatures return to the state by the end of the week.

 

Winter storm coats Iowa in sheet of ice, travel slow

News, Weather

January 16th, 2017 by Ric Hanson

Ice-covered tree limbs are snapping across a wide section of Iowa, causing hundreds of power outages. An Ice Storm Warning is posted for much of western and central Iowa, stretching as far east as Waterloo. Meteorologist Brad Small, at the National Weather Service bureau in Johnston, says that layer of ice is making travel very slow-going.

State and local crews are spreading sand, salt and brine on the roads, feverishly working to make those thoroughfares passable, but the elements aren’t cooperating. “Air and road temperatures are hovering right around the freezing mark, plus or minus a degree or two,” Small says. “There will be some melting today but unfortunately, with this additional rain, we could see additional accumulations of ice. Temperatures for highs will only be the mid-30s at best and that’s only over southern Iowa.”

Sometimes, even the road crews get into trouble. Earlier this (Monday) morning, two Adair County snowplows and a County truck spun off White Pole Road into the ditch south of Interstate 80. No injuries were reported.

Tuesday morning’s commute should be much better, Small says, as the road crews will have had a full day or more to combat the sheets of ice. “Tomorrow, there could be some minor melting but the good news is, we don’t have any precipitation in the forecast into mid-week,” Small says. “We may actually see highs in the 30s and 40s and possibly even 50 or more by Thursday.”

In southwest Iowa, about 62 customers of the Southwest Iowa Rural Electric Cooperative were without power in Taylor and Ringgold Counties, combined, and minor, scattered outages were reported by Mid-American Energy in Pottawattamie County. The few customers affected in Pott. County had their power restored by 9-a.m. or so. As of 9:30-a.m., Alliant Energy reported 64 customers were affected by an outage in Adair County, 90 in Madison County, and 27 were affected in Union County.

Power outages were worst in the Des Moines metro as MidAmerican Energy reported nearly 24-hundred customers had no electricity earlier today, though the utility say most are now back online.

Ice threat lingers for some Midwest states; storms in Texas

News, Weather

January 16th, 2017 by Ric Hanson

DES MOINES, Iowa (AP) – A few states in the Midwest again are on alert for icy conditions, while strong storms are moving through the Houston area. While the weekend’s storm caused travel issues in parts of Oklahoma and Kansas, some meteorologists acknowledged it fell short of dire forecasts. Kansas, Nebraska and Iowa are expected to see a mix of rain and freezing rain today (Monday).

Strong storms moved through Houston on Monday morning, following a night of storms.  There was at least one tornado in Texas on Sunday evening, and severe weather kept some fans, the Packers and a few Cowboys inside Dallas’ AT&T Stadium for more than hour after the NFL divisional playoff game on Sunday night.

In southwest Iowa, only scattered power outages were reported this morning, due to icing.

More ice still on way to parts of Nebraska, Iowa

January 16th, 2017 by Ric Hanson

OMAHA, Neb. (AP) – Travel remains hazardous in parts of Iowa and Nebraska as ice storms move north and east through the states. Authorities say most roadways that have been treated in anticipation of sleet or freezing rain are safe for cautious navigation. But untreated sidewalks, streets and rural roads could be treacherous Monday.

Fears of widespread power outages Sunday and early Monday have not materialized. Major utilities in both states report that fewer than 20 customers don’t have electricity. Air travel is problematical. More than 20 Monday departures have been canceled at Omaha’s Eppley Airfield and five at Des Moines International Airport.

National Weather Service meteorologist Josh Boustead says more rain is expected in both states Monday, but the temperature in most spots is hovering above the freezing mark.

Roads around western Iowa are reported to be partially covered with slush, and bridges are icy, early this (Monday) morning. That’s according to the Iowa DOT’s 511ia.org website. Sidewalks and parking lots are icy to slushy. Be especially careful on untreated surfaces. When driving slow down, and allow yourself plenty of space between your vehicle and the one in front of you. Intersections and untreated streets  may be slippery, so allow plenty of stopping distance.

Road conditions as of 5:55-a.m. Roads in blue are partially covered with slush & ice. Green indicates normal winter driving conditions.
