A wild week of has prevailed over much of the United States, bringing record high temperatures for many and fog and cool temperatures for others.  These weather extremes have been caused by a large and very deep upper level storm system which stalled over the Rockies Sunday.  Large amounts of warm air were able to stream into the Southern and Central Plains, with temperatures running some 20 to as much as 30 degrees above normal from Sunday through Tuesday morning. 

 

By Monday afternoon, cloud cover clear allowing numerous daily records to be broken across the Plains, with some locations such as Topeka, Kansas and Columbia, Missouri breaking all-time January records. The warm air remained in place over the region, as a warm front surged northward into Iowa and Nebraska Monday evening.  In fact, temperatures were so warm that record high temperatures for Tuesday were broken shortly after the midnight hour.  How close was Kansas City to breaking the all-time January high temperature record?  Well, the high temperatures of 74 degrees fell 1 degree short of the January record of 75 set back on January 24, 1950!

 

 By Monday evening, thunderstorms began to develop across Kansas, Oklahoma, Missouri, and Iowa, marking the beginning of what would be a widespread rain event for the region and potentially widespread severe weather event over the Southern Mississippi River Valley.  Rainfall totals have averaged between 1 and 2 inches over much of southeastern Kansas and central/western Missouri.

The story continues however, as we're just beginning to enter part two of the rapid cooldown and a return to winter weather.  A cold airmass continue to plunge into the Plains, and this airmass will bring accumulating snows to Missouri, Kansas, Nebraska, and Iowa by Wednesday morning.  Stay tuned as this story will be updated with snowfall totals Wednesday or Thursday.
