Winter weather advisories in effect across the Tri-States. Staying tuned to the forecast and road conditions will be very important, especially if you have to be on the roads.
Snow will really start to impact NE Missouri by 9 am spreading NE across the Tri-States. At first, snow will be light then picking up in intensity. Snow will begin to transition from snow to a wintry mix NW to SE early this afternoon. Sleet and freezing rain will likely impact the afternoon and evening hours before switching over to rain late evening and overnight. Any lingering rain will wrap up early tomorrow morning followed by an arctic air blast.
Snow accumulation: 1"-2" Quincy and farther south. 2"-3" with isolated areas 4"+ north of Quincy. Sleet and freezing rain may drop these amounts. Roads will likely become slick later this morning due to snow cover.
Ice accumulation: 0.10"-0.20" will be possible for everyone. The amount of ice won't change the impact on the roads, no matter how much it will cause very hazardous conditions. Once the sleet and freezing rain begin, conditions will quickly deteriorate conditions even further. Black ice is hard to see. If you have to be on the roads, drive with caution.
Larger amounts of ice near 0.20" may impact powerlines by weighing them down. Winds will be gusting up to 30 mph at times, so isolated power outages are possible.
Rain accumulations: 0.50"-1" possible with greater amounts southeast. The ground is already saturated from last week's system, so flooding will be possible for some. Pike and Scott County will be under Areal Flood Advisories tonight, meaning gradual minor flooding will be possible in low lying areas and small rivers.
Overall Impacts: Roads becoming slick once the snow begins reaching the ground this morning. Sleet and freezing rain will only make conditions worse. If you must be on the roads, drive slowly and with caution. It will not take a lot of ice to quickly change conditions. Thankfully, temperatures will be reaching above freezing later tonight/overnight.
Temperatures tomorrow will start out in the upper 30s and low 40s, by the afternoon temperatures will be in the 20s. Sunday is shaping up to be a brutally cold day. Temperatures starting off in the single digits near zero with wind chills at least 15 below zero. Highs on Sunday will be in the 20s. While MLK Day will be another very cold day there will be a warming trend next week.
