as it struck a brick apartment building, when was unroofed and

Sunday Severe Weather

Eastern Iowa saw a very active period of weather during the overnight hours Saturday into Sunday morning.  At least 21 reports of damage were reported to the National Weather Service.

storm report

Just outside our viewing area in Hardin County, an 88 mph wind gust was reported in Steamboat Rock just after 4 O’Clock in the morning.

88

Here are a few satellite and radar images as the storms tracked through eastern Iowa.

storm 1 storm 2 storm 3

The bowing segment is indicative of some very strong winds, and that was realized in many areas as the storm tracked through.

As of Sunday night, two tornadoes were confirmed in extreme eastern Iowa; Jackson County and Scott County early Sunday morning. (Click the link for details on the two tornadoes).

Confirmed Tornadoes on Map

Two areas in the KWWL viewing area that were especially hard hit are Vinton and Walford.  The National Weather Service in the Quad Cities will be sending out a team to survey those areas in Benton and Linn counties to determine whether the damage was caused by straight-line winds or a tornado.  Expect that report out sometime on Monday.

Several photos came in from KWWL viewers.  Here is a slideshow of some of those photos.

Severe Storms Tuesday Night

Severe Wx Risk for web
We are tracking storms forecast to move through eastern Iowa tonight…mainly after 9 or 10 PM. An isolated shower or storm is possible before this time, but the more widespread storms will be after and through the overnight. Heavy rain, damaging wind and large hail are the primary threats with the storms. The storms are forecast to end between 4-6 AM Wednesday.

Most of Wednesday is dry with a slight chance of an afternoon shower/storm. High temperatures remain in the mid-upper 80s and humid. We are tracking another round for storm possible for late Wednesday night into Thursday morning. Again the main threat of any of the storms would be heavy rain, damaging winds and large hail.

Friday through Sunday is dry, a bit cooler and less humid before the heat and humidity with storm chances return early next week.

Strong storms cause damage in Bremer County

The KWWL Storm Track 7 Weather Team was tracking a line of heavy rain and strong thunderstorms Thursday afternoon.  Some of those storms had gusty wind and small hail, along with heavy downpours and lightning as they tracked through parts of eastern Iowa.

One of the hardest hit areas was Denver in Bremer County.  The storm was at its strongest as it was over the town, producing quite a bit of pea to dime size hail and damaging wind gusts.  Here’s the storm at 2:31 PM as it was affecting Denver.

KWWL received several reports of trees being blown over, and hail covering the ground. (See the photos to the right)

KWWL 2015 MAX Storm ED Storm

These storms developed ahead of a cold front that is moving through the area.  Rain chances will continue through about 6 PM, and we will see decreasing clouds overnight.Viewer Photo Basic 1 Vertical Viewer Photo Basic 2 Vertical Viewer Photo Basic 21236
