Numerous Severe Storms With Large Hail and Damaging Winds Affect Mainly Western Counties...Cause Significant Crop Damage

To the right is a National Weather Service Radar loop, valid from 3:30 p.m. on Wednesday, July 9th to 5:00 a.m. on Thursday, July 10th.

The NWS Hastings coverage area is located within the orange outlined area labeled "GID", with the Interstate highways in red.

Event Summary:

Starting during the late afternoon hours of Wednesday, July 9, 2014, and lasting into the early morning hours of Thursday the 10th, primarily the western half of the NWS Hastings coverage area (mainly west of the Highway 281 corridor) was raked with numerous severe thunderstorms that generally tracked from northwest-to-southeast. The first severe storms entered the local area into Valley County around 5 PM, and the final severe storm of the event affected mainly southern Gosper County around 2 AM. As a result, despite some "lull in the action" mainly late in the evening, this was a fairly long-duration event with severe storms affecting the local area over a span of nearly nine hours. 

Although one Tornado Warning was issued for the Gibbon area around 7 PM based on radar-indicated rotation, there have been no verified observed/confirmed reports of a tornado as of July 10th. However, many of these storms produced considerable damage (primarily to crops but also to some structures) due to a nasty combination of hail and strong winds. Although many of the most significant reports of large hail and damaging winds are summarized in the bulleted section below, one can generally say that several storms contained copious amounts of mainly small hail up to quarter size, along with isolated larger hail up to around golf ball size, accompanied by straight-line winds of 50-70 MPH. An unofficial home weather station two miles northeast of Norman in Kearney County reported a gust as high as 85 MPH. Needless to say, these severe storms resulted in several generally northwest-to-southeast swaths of significant crop damage, some of which extended for dozens of miles.

As for heavy rainfall, although no widespread, significant flooding was reported or detected during this event, there were several instances of mainly short-term, minor flooding as a good chunk of the NWS Hastings coverage area received 1-2" of rain in a fairly short time, along with limited coverage of amounts in excess of 2". Per NWS cooperative observers and NeRAIN observers, a few of the highest storm-total rainfall amounts included 3.34" four miles southwest of Blue Hill and 2.70" four miles north of Gibbon. 

In forecast hindsight, even though there were expectations for at least a few severe storms to develop during the late afternoon and evening of the 9th, this event ended up being more widespread/longer-lasting than originally anticipated. Although atmospheric instability was not unusually high for this time of year, deep-layer wind shear was fairly impressive by July standards at 40-50+ knots, which allowed some storms to become supercells and stay severe for a longer time (the mid-summer months usually have weaker wind shear compared to the peak severe weather months of April-June).
