If you are not a weather geek, you may wonder – what is  snow squall?  The meteorologists says it s a brief but heavy snowfall, under an hour in duration, that can wreak havoc on roadways if timed during a rush hour.

The National Weather Service issued a Special Weather Statement early Wednesday saying such squalls are locally possible 2-8 pm Wednesday, right in the middle of evening rush hour traffic.

Hamilton County Emergency Management advises motorists to take it slow with snow squalls possible this afternoon and evening.

Here is part of the statement from NWS forecasters:

Snowfall rates will be locally heavy at times producing
drastically reduced visibilities and brief whiteout conditions as
winds gust to around 40 mph. As temperatures fall late today into
the evening...flash freezing of surfaces will also be possible.

Conditions can deteriorate rapidly within heavy snow showers with
little warning. Traveling will likely be hazardous at times,
especially during the evening commute

Bottom line – be careful out there.
