From Decatur County EMA Director Brad Speer
Given the strong forcing, plentiful moisture, and long duration of
the event due to the orientation and motion of the primary
precipitation band with the system, probabilities are still high for
warning criteria of 5 inches, especially for areas along and south
of I-70. For this reason a Winter Storm Warming remains in effect,
Greater uncertainty resides for NW portions of central Indiana,
where a sharp northward gradient in snowfall totals is expected. For
now a warning continues in these areas until greater certainty in
the alignment of the snowfall gradient is obtained.
Greatest snowfall amounts are likely to remain near or south of the
I-70 corridor. The current forecast is for snowfall totals as high
as 12 inches. Areas that see any mixing of sleet or freezing rain
will likely see some decrease in snowfall totals, but impacts could
still be just as bad due to ice accretion. Winds will also be a
concern, particularly tonight into Monday, with blowing and drifting
likely becoming at least a moderate concern in areas that did not
receive freezing drizzle Sunday night. Winds gusts between 30-40 mph
are expected with a low chance for isolated higher gusts.
