At 800 AM CST...Several areas of low pressure were located along a
strong frontal boundary extending from the Colorado Rockies
eastward into the Northeast. The strongest low pressure was
located in the panhandle of Texas with a central pressure of 999
millibars or 29.50 inches of mercury. A cold front extended
eastward from this low pressure into central Oklahoma, southern
Missouri and Illinois and into central Indiana and Ohio. Several
additional areas of low pressure were located along this frontal
boundary. Current RADAR and surface observations indicate moderate
snow had been falling in the central Plains and Midwest north of
the cold front. A thin area of wintry precipitation extended from
central Oklahoma into southern Kansas and central Missouri. South
of the frontal boundary, a broad area of moderate to heavy
rainfall stretched from southern Oklahoma eastward through the
lower Mississippi Valley and Southeast, and into the Mid-Atlantic.
Pockets of heavier rainfall have developed along a secondary
frontal boundary that reached from southwestern Arkansas into
extreme western Tennessee and Kentucky.

Over the next 12 hours, the streghtening storm system along the
strong frontal boundary will produce a broad swath of 6-12 inches
of snow across the Great Plains and Midwest. An area of freezing
rain and sleet will be possible from eastern Kansas extending into
Missouri and central Illinois, where ice accretions of 0.01 - 0.10
inches may occur. On the southern side of the frontal boundary,
heavy rainfall amounts are likely, leading to a Moderate Risk of
excessive rainfall being issued by the Weather Prediction Center
for central Arkansas, southern Missouri and Illinois, Kentucky,
southern Ohio and western West Virginia. Rainfall totals within
the Moderate Risk are forecast to range between 2 to 4 inches with
locally higher amounts possible. In addition to the potential for
flash flooding, the Storm Prediction Center has issued an Enhanced
risk of severe thunderstorms for western Tennessee and northern
portions of Mississippi and Alabama, where the threat of damaging
winds and tornadoes will increase as we continue into the
afternoon and evening hours.

The next Storm Summary will be issued by the Weather Prediction
Center at 900 PM CST. Please refer to your local National Weather
Service office for additional information on this event.
