Series of Pacific Northwest Storms; Wintry Mix in the Northeast and Parts of the Mid-Atlantic

A series of Pacific storm systems will cross the Northwest U.S. this week bringing gusty winds, high surf, periods of heavy rain, and mountain snow. Another storm system will continue sweeping through the Northeast and Mid-Atlantic Tuesday with a wintry mix of snow, sleet, and freezing rain making for hazardous travel. Read More >

Overview

A low pressure system moving across the central United States with an associated cold front and dry line initiated thunderstorms in southern Nebraska, the eastern half of Kansas and central Oklahoma. These storms produced swaths of wind damage and large hail.

Hail

A range of hail was reported with the largest values of 2" or egg sized hail in Cheney and 3 SW of Goddard in Sedgwick County. Central Kansas did have reports of golf ball sized hail (1.75") at two locations: 3 SW Beverly and 3 S Lincoln on Kansas Highway 14.

Large hail has been reported near Cheney. This picture indicates it may be larger than golf ball size. @NWSWichita pic.twitter.com/y7VUEsuw3C

Radar:

There were radar features including a comma and hook that could be found on the base reflectivity of the KICT radar. Since this storm was very close to the radar, a secondary radar called KVNX out of Oklahoma was utilized to better fully assess the storm. KVNX showed an inflow notch feature instead which is common with High Precipitation (HP) storms. The assessment of velocity showed broad rotation which would suggest strong winds versus tornadic activity.


Comma shaped storm in NW Sedgwick County at 6:57pm.	This velocity image from the KVNX radar shows broad rotation at 6:57pm.	A zoomed in version of the reflectivity in Sedgwick County at 7:13pm.	A zoomed in velocity image from the KVNX radar once again shows broad rotation at 7:13pm.
