Understandably, the topic of conversation in Omaha this weekend was the big storm that blew through there last Friday, and the impact is still quite visible with power still out in parts of the city and large trees blocking residential streets.
The National Weather Service is now saying that wind speeds clocked as high as an EF2 tornado at times. In Elkhorn, one spotter observed average wind speeds of 80 mph for three minutes, giving residents a sense of what a hurricane must be like. People spoke of a huge, dark cloud descending to the ground as the storm was moving through the vicinity near 72nd and Dodge, with the cloud rolling horizonally, greenish in color. I drove through an area that had 3 huge ash trees uprooted. Garages exploded, power poles were snapped in half. At my home, my wife woke up the next morning with ice still remaining in the yard from the night before; the remnants of pea sized hail that drifted along the house. For some on the west end of town, near 168th, that wind driven hail shredded house siding and tore off shingles. Even chain link fence (and don’t ask me how this happens) was topped by the wind.
I think everyone is ready to close the book on the month of June. Lets hope July reigns much more peacefully.

Lots of things going on with the atmosphere this afternoon though not readily apparent to the naked eye. With all the humidity in place an outflow boundary, clearly visible on NexRad Radar, pushed east across highway 281 with little consequence thanks to a cap inhibiting thunderstorm development. However just south of the Kanas/Nebraska border storms did fire producing strong winds and hail up to golfball size. As of 7:30 these storms have moved very little so flooding appears like it will be imminent in Republic and Cloud counties in Kansas.
Out west, storms are lining up and expected to join into a complex pushing east affecting the Tri-Cities area late this evening. Still some question as to instablility east of a boundary late so will be monitoring as the evening wheres on. Strong downbursting winds and hail the main threat.
A Severe Thunderstorm Watch is effective until 1 am for western Nebraska and counties either side of the state line in Nebraska and Kansas. Kearney, Lexington, Holdrege, Superior, Hebron, Smith Center, Franklin, Alma among some of the towns included. Hastings, Grand Island and York our outside of the watch area. Stay tuned to News 5 for the latest in storm coverage

A complex of thunderstorms is tracking across the very northern fringe of Nebraska, right along the border through north central Cherry county. Beyond that it has been particularly quiet. Warm air aloft has us capped for the time being, meaning thunderstorms are inhibited from developing. The two isolated storms that did develope were quickly snuffed out with little consequence.
As the low level jet, or winds at about the 1000 foot level, kick in overnight the possibility exits of isolated thunderstorms still developing. Widespread coverage is not expected and the threat for severe weather will be minimal.

As of 11 pm, I’ve continued to monitor active thunderstorms pushing through the panhandle. These storms continue to propogate descreet cells into a line running from the South Dakota border into eastern Colorado. The RUC model is suggesting a 35 knot low level jet and storms pushing into a more moisture rich environment so I’ve decided to add a chance for T’storms in our viewing area. I I’m weighing chances to be a little higher for those counties west and north of the Tri-Cities, roughly along and west of a line from Bartlett to Kearney. Will continue to monitor.

Thunderstorms are now active in the High Plains of Wyoming and eastern Colorado and are begining to find their way into the Cornhusker state. While the atmosphere out in western Nebraska is fairly dry, low pressure in Colorado will continue to pull up moisture on southeasterly upslope winds which will allow storms to continue to spread. With low level jet stream winds interacting late this evening, storms will maintain themselves and produce some strong winds, hail and potential 1 to 3 inch rains south of the I-80 corridor.

The threat for tornadoes has appreciably subsided as we head into the mid evening hours. At 7:45 two storms really have our attentiion. One is northwest of Sutton and will slide through Fillmore county toward highway 81. This storm has kicked out healthy outflow winds of up to 60 mph which is the primary threat along with some hail. This storm cluster is moving southeast at 31 mph Torrential rainfall also associated with this storm
The other area of concern lies in southeast Gosper county just about to cross highway six into northeast Furnas and NW Harlan. Hail to 1″ in diameter and is trying to strengthen..
