The coldest air we have experienced in December since 2008 is now moderating. Today's morning low of 20 degrees is 12 degrees above yesterday's frigid low. Our attention now turns to the low pressure system that will be moving out of the southern plans and through the Ohio Valley. The low will then transfer the energy to an East Coast low pressure that will track quickly up the coast. This system will produce moderate and at times heavy snowfall across the area starting Friday night continuing through much of Saturday. Snowfall amounts of between 3-6 inches are likely with this system by the time the snow ends Sunday morning. Light additional accumulations from lake effect are possible on Sunday before everything wraps up. High temperatures Friday will rise into the upper 20's and near freezing on Saturday before dropping into the mid 20's on Sunday. Monday is looking like a quiet weather day with chance of light snow and high temperatures in the mid 20's.
Low pressure will organize over theSouthern Plains on Friday before moving through the Ohio Valley on Satrurday
Low Pressure with an inverted trough will move through the Ohio Valley on Saturday while another low pressure will develop off the Mid-Atlantic Coast. It will produce a general snowfall for the area with totals generally 3-6 inches.
High pressure will provide a quiet day for the area on Monday. Temperatures will remain cold with high temperatures remaining in the mid 20's
Looking ahead into late next week. The weather pattern is still trending towards a moderate. The amount and how long it will last is still undermined due to large differences between the models. Early next week, we will take a closer look at how the pattern will evolve once the models converge on a solution.
