Weather conditions on Valentine's Day were not so sweet as intense northwest winds buffetted the Central Plains.  A strong upper low pressure system advanced south from the Dakotas and across eastern Nebraska during the morning, then moved into Missouri in the evening.  A strong cold front accompanied the system and in a tight pressure gradient on the back side of the low, northwest winds increased to 30 to 35 mph and had gusts well over 40 mph.  The tri-cities and the Aurora Airport all reported peak wind gusts over 50 mph.  (The peak wind gusts are listed in the table below.)  Afternoon high temperatures only reached the teens in York, the 20s across south central Nebraska, and north central Kansas saw some highs near the freezing mark. 

A band of snow moved across central and eastern Nebraska during the morning and began to diminish as it reached north central and northeast Kansas in the afternoon.  The snow was more prevalent along and east of a line from Genoa to Aurora to Superior, and the snow combined with the winds to produce white out conditions at times in the morning.  The National Weather Service cooperative observer in the Gresham area (York County) reported that 3 inches of new snow had fallen.
