No Change in Forecast as Models Continue to Waffle

I will not change my initial forecast from Monday with the first low pressure riding from the Plains through the Ohio Valley and turning northeast. As the energy transfers to another area of low pressure deepens off the East coast to the north. Some models have continued to slow down the strengthening of the first low pressure. Thus the track will be more west to east from northern Oklahoma to central Kentucky. Models usually have some waffling around the day 4 and 5 time frame but usually hone in by day 3. So that's why I'm waiting to put a true snowfall forecast until tomorrow afternoon.

Still looks like heavy snow, high winds and very low windchill values are in store for most location east of the Mississippi valley. Time frame of this winter event will start on Saturday and start winding down on Monday across the Northeast.
