Watches & Warnings

Special Statement
Issued: 3:01 PM CST Nov. 12, 2018 – National Weather Service

... Ice and snow possible this evening...

A wintry mix of precipitation can be expected to slowly work
southeast across parts of the quad state region, persisting into
the evening and overnight hours.

The vast majority of the region will see just rain through sunset
with temperatures in the lower 40s. But some locations in
southeast Missouri and southwest Illinois could see patchy sleet
occur on the leading edge of the rain.

As temperatures fall after sunset, the rain will gradually mix
with then change over to sleet, freezing rain and snow during the
evening hours. This is especially true for southeast Missouri and
southwest Illinois.

The best chance for seeing any accumulating sleet and snow this
evening will be along and north of a line of Piedmont and
Perryville Missouri, Onward to Ava, Duquoin, Mount Vernon, and
Cisne Illinois. Snowfall amounts could range from one to three
tenths before the precipitation ends overnight.

In addition to the snow and sleet, up to a tenth of an inch of ice
may accumulate on elevated surfaces along and northwest of a line
from Piedmont to Marble Hill and Perryville Missouri.

The coldest air will reside along the foot hills of southeast
Missouri and parts of southwest Illinois through midnight, before
working southeast to the Ohio and Wabash rivers by 3 am CST.

Patches of light freezing rain will be possible over southern
Illinois and the remainder of southeast Missouri during this time.
However, as the freezing air moves in, most of the measurable
precipitation will be exiting the area overnight. Very little, if
any freezing rain accumulation is expected.

As temperatures fall into the middle and upper 20s overnight, any
precipitation left on untreated roads and bridges will freeze and
may become slick and hazardous. For those traveling in southeast
Missouri and southern Illinois late tonight or early Tuesday, be
watchful for black ice and exercise caution while driving.

Another winter system is slated to return to the quad state region
Wednesday night into Thursday, so travelers and residents should
take measures to prepare for more wintry weather later this week.
