668 NOUS44 KAMA 012243 PNSAMA OKZ001>003-TXZ001>020-317-021045- Public Information Statement National Weather Service Amarillo TX 543 PM CDT Tue Jun 1 2021 ...NWS DAMAGE SURVEY FOR 05/30/21 TORNADO EVENT... ...DALLAM AND SHERMAN COUNTY TORNADOES... Sunday May 30th, 2021 saw multiple tornadoes in the northwestern Panhandles. Persistent low level winds out of the east brought substantial moisture to the region, allowing for thunderstorms to break out as an upper level disturbance approached from the southwest. With the surface winds out of the east in place, low level shear was sufficient for multiple tornadoes to develop with these thunderstorms, with 6 tornadoes confirmed in Dallam and Sherman Counties. 5 of these tornadoes occurred over open land, did not affect any damage indicators, and were thus unable to be assigned a rating. In addition to the Dallam and Sherman County tornadoes, tornadoes also occurred in Cimarron County on the 30th. A subsequent PNS will be issued covering survey results from these tornadoes. .Northwest of Conlen 1...
