Widespread Precipitation and Snow Across the Pacific Northwest; Heavy Rain and Severe Thunderstorms Across the Central and Southern U.S.

Widespread precipitation is expected across the Northwest and northern Rockies through Monday, including heavy mountain snow for parts of the region. A powerful storm is expected to bring periods of heavy rain, gusty winds, and the potential for severe thunderstorms throughout the southern to central Plains between tonight and Monday. Read More >

Thanks to westerly breezes overspreading the Central Plains ahead of a strong cold front, an unusually warm airmass for mid-October developed on Sunday, Oct. 11, 2015, resulting in not only daily record high temperatures, but also record high temperatures for the entire month of October!

Although NWS Hastings collects climate and weather information for numerous official NWS observation sites across South Central Nebraska and North Central Kansas, the only sites for which "formal" record statements are issued are Grand Island and Hastings airports. Details for these two primary sites follow below...

 


Grand Island (Central Nebraska Regional Airport):

On Oct. 11, 2015, the high temperature at the Central Nebraska Regional Airport in Grand Island soared to 97°. This was an incredible 30° warmer than the "normal"/average Oct. 11th high of 67°.  

  • This broke the previous daily record for Oct. 11th of 93° set in 1928.
     
  • More significantly, this also set a new October monthly highest temperature record (for any day), eclipsing the previous mark of 96° set on Oct. 5, 1947.
     
  • In addition, this marked the latest occurrence of 97°-or-hotter on record during a calendar year, beating the previous latest mark of 97° on Sep. 28, 1953 by nearly two weeks!

The image below includes surface analysis maps, the left showing maps from 1:30 p.m. October 5, 1947 (the previous highest October high temp record for Grand Island/Hastings) and the right is from 1 p.m. this afternoon. Note that both record breaking/tying days involved our area being ahead of an approaching cold front in the western Dakotas with a trough axis extending through the area...allowing for more westerly winds to develop and deeper mixing into warmer air aloft.
