Major Storm Late Week, Impacts In Any One Place Uncertain

A major weather system is headed toward the Ohio valley for the end of the week. After a brief January thaw, heavy rain will transition to a wintry mix then snow. Many are asking how much snow. At this point, it is impossible to say. It is worth noting that it is likely this storm will be crippling for someone in the heaviest snow area. It is just impossible to say who, although Cincinnati is in play at this point. Prepare for a major winter event but remain aware that it is too early to say exactly where. Be aware that travel may become difficult or impossible in the heaviest snow area and recovery may be slow. Areas just southeast of the heaviest snow could have significant sleet or ice while areas northwest of the heaviest snow will have lighter snow and wind. Heavy rain and flooding may also be possible before the snow with over 2 inches of liquid possible. What do we currently know? See below:

Central Ohio.

 

A low pressure system is forecast to move northeast from the
Tennessee Valley to the eastern Great Lakes Friday into Saturday.
Rain is expected to transition over to a wintry mix Friday afternoon
and then gradually changeover to snow Friday night. Accumulating
snow and ice will be possible with this system. Any slight track
differences with this system will have large implications on the
potential weather types and impacts. This weather event will have to
be watched carefully as the week progresses.

Cold then warm then…

As we look forward to warmer temps this week, Dayton (4.1 Fahrenheit) and Cincinnati (8.5F) had their coldest Jan 1-6 on record while Columbus (7.9) had its 2nd coldest Jan 1-6 on record.

Temperatures could peak near 60 by the middle of this week but don’t get too used to it.

A strong storm system will organize for late in the week then move east. It will begin

It looks likely that this storm will turn into a big and nasty winter storm with severe storms over the south and heavy snow or even a blizzard to the northwest of the center. The $64,000 question is where will the storm track? It is too early to tell. However, significant impacts are possible in Cincinnati at this point.

Stay tuned.

After a few days of more bitter cold next weekend, it should again turn warmer for a week or two before winter sets in again for February. Winter is in gear. It may go away for a bit but there is lot more winter to come and this weekend could be one installment.
