Cold. Snow. Sleet and freezing rain. We have a lot going on and this is the latest information coming in Friday morning.

First of all, let's talk about our advisories and warnings.

The NWS has now elevated the area to a WINTER STORM WARNING starting Satuday at 10 a.m. and continuing through noon Monday.

FRIDAY: Today it's all about the cold! We'll see temperatures holding in the upper teens for the morning and early afternoon hours. By 4 p.m., we'll only be at 15 degrees under a partly cloudy sky. Today is dry. Today is your last "easy" day to get things done and run errands!

FRIDAY NIGHT: The forecast remains quiet tonight but incredibly cold. Our low of 4 degrees will feel like -12. Bundle up!

SATURDAY MORNING: The day starts dry, cold and cloudy. Snow will begin to fall in our southern locations between 10 a.m. to noon. This will be very light to start.

SATURDAY AFTERNOON: Snow is likely. It will be slow to accumulate at first, and then it will just start blanketing everything. We could see a few inches of snowfall by the time the sun sets. Temperatures will also be very cold in this timeframe, only warming to 15 degrees. I wouldn't describe road conditions on Saturday as "impassable" but they will get more and more difficult late in the evening.

SATURDAY NIGHT: Snow continues! Light to moderate snowfall will come down all night, just adding to our totals. By the time the sun rises on Sunday morning, we could be looking at 4-8" of snow on the ground.

SUNDAY: Sunday's forecast is where things get a bit more complicated. Yes, snow is going to continue, especially if you are in our northern locations. But to the south and southeast, sleet and freezing rain will also fall. This could impact our overall snowfall numbers in those regions.

We still have high confidence that everyone will see 6+ inches of snowfall. But with sleet in the equation on Sunday, that could really mess up the numbers to the south. If snow holds on long enough, our snowfall numbers would just continue to climb to well above 10". But if sleet takes over for a long period, that will bring down snowfall expectations.

Either way, snow or sleet, roads will not be in good shape.

Sunday is the day that roads will be incredibly difficult or impassable at times. The impact on travel conditions will linger into Monday morning. It is going to take a while to clear all this snow, sleet and ice!
