Bitterly Cold

The forecast models are consistently showing wave after wave of Arctic air affecting the Midwest and Ohio Valley over the next several weeks.

One of the main reasons this is occurring is due to something that is called the Arctic Oscillation which has recently reversed and gone negative. This will allow the Arctic Air that is pooling in Canada to swing into the Northern United States and Midwest.

As a ridge builds across the Western United States, troughs of low pressure will swing down with associated colds fronts every few days which will ultimately usher in new and colder air masses every few days across the Midwest.

It appears that this November will fall well below normal as far as temperatures are concerned and this November could be one of the coldest Novembers in over a decade if the pattern materializes like I think it will.

The first wave of Arctic Air will arrive this weekend, with high temperatures only climbing into the 30's and lows at night falling well into the 20's. A second frontal passage will occur early next week, followed by a second Arctic airmass with bitterly cold air intruding into the Midwest and Ohio Valley.

A brief warm up will occur next week before a third Arctic outbreak occurs around the 20th of this month.

There are also signs that around the 20th or 21st that a significant weather system could affect the Ohio Valley and with cold air in place, its not out of the question that somewhere across the region could see accumulation snow.

All I have to say is that Old Man Winter is definitely making his presence felt, and for that matter its not even officially Winter yet! One thing is for sure.........get the Winter coats out and crank up the heat, because the cold is here to stay!
