Arctic Air Spreads South and East from Rockies Friday through Next Week

Arctic air is plunging across the Rockies and Great Plains and will reach the Deep South and Great Lakes Saturday night, and the Eastern Seaboard by Sunday night, bringing dangerously cold wind chill temperatures. Snow and heavy winds could produce blizzard conditions in the Northern Plains Friday. There is a wintry mix expected in the Midwest/Northeast and rain for the Southeast into Saturday. Read More >

Overview:

In what had been a quieter-than-average severe thunderstorm season within the 30-county NWS Hastings coverage area, the event on the evening of Tuesday, June 13th was likely the most significant/widespread of the year-to-date. Primarily between 6 PM-11 PM, a rash of severe storms consisting of both semi-discrete supercells and also linear clusters yielded dozens of large hail and damaging wind reports, primarily within a 30-50 mile wide corridor centered roughly along a line from Phillips/Smith counties in the southwest, then northeast through the Red Cloud, Hastings/Grand Island, Clay Center, Aurora and Osceola areas.

Some hail was quite large, highlighted by stones up to baseball size reported just west-southwest of Hastings (including in the Juniata and Holstein areas) and up to tennis ball size within Grand Island. Although stones this large were the exception overall, many affected areas saw at least quarter to ping pong ball size hail. As for damaging straight-line winds, the overall-worst impacts focused within counties east of the Highway 281 corridor. In west-central Polk County, a home weather station clocked an unofficial gust of 92 MPH, with gusts of at least 70 MPH also reported in the Clay Center and Bradshaw areas. Needless to say, there was quite a bit of mainly minor damage to trees and outbuildings across the area, including in the communities of Osceola, Shelby and Hordville, among others. Fortunately, there have no official confirmations of tornadoes (as of this writing), although storm chasers reported gustnado activity along the leading edge of storm outflow.

Rainfall-wise, most areas affected by these storms reported totals between 0.50-2.00" from the evening of the 13th into the early morning of the 14th. However, there were some locally-higher exceptions, including in the Loup City area, and also near the intersection of Webster, Franklin, and Smith counties, where unofficial reports of up to around 4" occurred. Fortunately, any flooding concerns were relatively minor and brief.

In the mid-upper levels of the atmosphere, this event was driven by a shortwave trough swinging east through the Central Plains, to the southeast of its "parent" closed low pressure system centered over Montana. At the surface, storms developed in explosive fashion as a dryline pushing in from the west encountered a very warm/unstable airmass characterized by afternoon high temperatures well into the 90s and dewpoints in the 60s.
