Mother Nature is bringing in some Christmas-time temperatures for the holiday! A very cold air mass will move into the Ohio Valley tonight. Lows will dip down into the upper teens by early Tuesday morning. A few light snow showers will be possible overnight and into the morning hours. Any isolated snow accumulation will be very light and less than half an inch.
Some sunshine will come out for your Christmas Eve but highs will still only reach the middle 20s. Take your winter coat to any evening church services on Tuesday night as temperatures will be dipping into the teens by 9 p.m.
Christmas Day is looking cold as well with a morning low around 15 degrees and a high near freezing. A stray flurry or two cannot be ruled out in the morning also so keep your eyes open for a snowflake or two!
The quiet weather pattern will last through the rest of week as will the chilly air. Highs will warm slightly on Friday into the upper 30s. A brief dose of mild air will be in store for Saturday as highs head for the 40s.
It appears as though another major outbreak of arctic air is in the works for the New Year’s holiday. As can be seen in the slideshow, forecast models are showing a –EPO pattern over Alaska developing again. This ridge of high pressure will cause our air to come from northern Canada and the Arctic. In addition, the Arctic Oscillation is likely heading negative meaning the entire jet stream could shift farther south bringing even colder air.
This is all still a week away, but just something to watch for on the horizon. Merry Christmas!
