A very strong area of low pressure moved up the east coast of the United States on April 23rd and 24th.  Strong northerly winds on the backside of this system ushered unseasonably cold air into the upper Ohio Valley.  This cold air moving across Lake Erie caused lake effect showers to develop.  Rain showers changed to snow showers during the morning hours of the 23rd.  Initially, the snow accumulated mainly on grassy surfaces but by late afternoon some travel problems were reported.  The snow intensified during the evening hours and then tapered off from west to east early on the 24th.  The higher terrain on the eastern end of Erie County saw the heaviest snow with a maximum of 10 inches reported near Corry.

A combination of rich moisture wrapping into Eastern Washington from the east and strong forcing approaching from the west resulted in heavy, banded snow showers across northern Spokane during the late afternoon of April 4th.  Due to the convective nature, the heaviest bands consisted of a combination of snow, graupel, and small hail.  These bands setup over North Spokane between Francis Street and Newport Highway producing two to four inches of slushy, snow accumulation between 1700 and 1800 PDT.  This resulted in multiple accidents across North Spokane and a hour road closure at the intersection of Division Street (Highway 395) and Magnesium Street due to the steep terrain and treacherous driving conditions.
