Flash flooding is also possible for portions of the Plains and Mississippi Valley. Very large hail up to 3 inches in diameter will be possible this evening across western Kansas. Read More >
Parts of the Area Dig Out From Surprise Heavy Snowfall
January 8, 2005
A fast moving but intensifying upper level disturbance affected most of the region late Friday night into early Saturday morning. Light snow began to develop in earnest across east central Missouri and southwest Illinois Friday evening in response to intense forcing within the exit region of a strong upper level jet streak and northeast of rapidly deepening mid level cyclone. This rapid deepening combined with intense forcing aloft underneath the upper level jet streak, a deep moisture plume advecting northward out of the Ohio valley, and ideal thermodynamic profile supporting large dendritic snow crystal growth all combined to support a narrow band of heavy snowfall over northern Indiana, roughly along and 25 miles either side of a Rochester to North Webster to Angola line. Snowfall reports from 5 to nearly 8 inches were observed in this band. Much of the snowfall occurred over period of only 3 to 4 hours. Here, at the Northern Indiana Weather Office, as well as a few other locations, snowfall rates as high as 3 inches per hour were observed. Figure 1 shows a radar estimated liquid precipitation equivalent for the event. Note the cyan and magenta colored areas which indicated the where the heaviest precipitation occurred.
