Quick weekend update on the developing winter storm and trough over the eastern portion of the United States. An weak area of low pressure currently located in northern Alabama will start to strengthen as it pulls north overnight into Sunday. As colder air dives in behind the storm a moderately strong upper level low pressure currently over Missouri. Helps strengthens the low pressure over Alabama as it heads towards Ohio.
This area of low pressure will not be as strong as thought earlier this week. As the upper level and lower levels never really phased together. Which would allow a transfer of energy to the east coast producing a deeper low pressure. So with that being said I would expect a wide area of snow showers across the Ohio Valley Sunday into Monday. The heaviest snow band with the low pressure will likely be north of the line from Saint Louis, Missouri to Lafayette, Indiana to Detroit, Michigan. In which I could see an isolated amount up to 6 inches but most area will receive 2-4 inches. Rest of the Ohio Valley will eventually see the colder air change the rain into snow but will likely see less than 2 inches of accumulation.

No matter what very cold air will come in two shots this week with the first shot this weekend and a bigger shot coming in mid-week. Which will likely produce high temperatures well below normal for alot of the Central and Eastern Unites States. We're talking high temperatures in the 20s across the Ohio Valley. I'll have another update on the Cold plunge later today or on Sunday.
