Temperatures made it well into the upper 30s this afternoon. Make sure that you bottle that warm weather feeling inside because it will be a long time before we make it that warm again. A very cold weather pattern is shaping up as a huge ridge of high pressure over western Canada forces polar air into the Great Lakes and Ohio Valley in several shots this week.
The first shot of cold air will come with accumulating snow tonight. With cold air rushing in, the snow to liquid ratio will be running quite high. (Possible as much as 20:1 whereas 10:1 is typical) This means we can squeeze out more snow from the same amount of liquid equivalent and that the snow will be fluffy and powdery.
With the snow starting overnight, the morning commute will likely be very rough. Plan ahead for extra driving time and slick roads.
Expect one to two inches of snow by mid-morning as the snow begins to wind down. Gusty winds will create blowing snow which means lower visibility and poor road conditions. In addition, the wind will drop the wind chill to near 0 degree at times. Air temps will fall into the teens by early morning and stay relatively steady all day. Higher amounts of snow will be possible south of Columbus. Anywhere from 2-5 inches may accumulate from southwest into south central Ohio.
Flurries may persist for much of the day, but the steadier snow will end by the middle of the morning. The bitter cold air will really filter in Tuesday night as lows head for 0 degrees. Highs on Wednesday and Thursday will both be in the teens.
Another weak weather system will bring light snow to the region Wednesday afternoon and evening. As of right now, it looks like a dusting to an inch will be possible.
Lows could dip below 0 by Thursday morning with wind chill readings below -10! The cold weather will stick around for at least the next 7 days and snow chances will continue as well. Several systems could bring accumulating snow potential this weekend, so stay tuned!
