Temperatures should warm above freezing around 9am and continue to the upper 30s around 40 from noon through the afternoon, melting ice and some snow. A refreeze is expected Wednesday night.

---OLD POST---

COLUMBIA - Another week in Missouri in the 2018-2019 winter weather season means another winter storm system. This particular system won't drop much snow or much ice over the region, but due to the combination of the two and the potential impacts to travel, it is still a system to respect.

Moisture is moving overhead this afternoon but is fighting through a very dry lower atmosphere. Snow onset is most likely between 6pm and 10pm from south to north through mid-Missouri, when the atmosphere finally becomes saturated.

Arrival: Eldon around 6pm. Jefferson City/HWY 50 around 7pm. Columbia/I-70 around 8pm. Moberly/HWY 24 around 9pm.

Snow will fall at a moderate speed and winds will gusts around 25 mph. This will lead to low visibility. It will begin accumulating on surfaces pretty quickly after it begins to fall. It will be more of a wet snow. This is because temperatures at the surface will be within two degrees of the freezing mark most of the night.

Eventually, between 9pm and midnight, warmer air will infiltrate the system. This will force snow to change into sleet (briefly) and freezing rain. This will create ice accumulations on surfaces and will wash away treatment on roads. 

The entire system is expected to exit between 6-9am on Wednesday morning.

ACCUMULATION

Areas along and south of the I-70 corridor will see more sleet, freezing rain and regular rain than snow and therefore snow accumulations will be lower, with 1 to 2 inches possible. Then, a glaze of ice up to 0.10" is possible. The lower accumulations are also because temps could periodically warm enough to produce regular rain, melting some of the previous accumulation. The further south of I-70 you are the better chance you have at an okay Wednesday morning commute.

Areas north of the I-70 corridor will see more snow and less of the mix, with 2-3", up to 4" of snow possible and a glaze to 0.10" of ice possible.

TRAVEL

We'll be tracking temps very closely. Slick road conditions are expected Tuesday evening through Wednesday morning, until temps go above freezing close to 8-10am. Travel is not encouraged during this time. There will also be blowing snow due to winds gusting around 25 mph; visibility will be low.

The good news is that temps should warm above freezing by late morning on Wednesday and this will leave the noon and afternoon commute in much better condition. Some areas may reach near 40 on Wednesday. 

Are you ready for spring? There is a good chance for spring-like rain showers on Saturday with high temps near 50.
