   Areas affected...Portions of central/eastern KS and western/central
   MO

   Concerning...Freezing rain 

   Valid 170920Z - 171515Z

   SUMMARY...Light to moderate freezing rain will continue to spread
   northward across parts of Kansas and Missouri this morning. Freezing
   rain rates around 0.05 inch per hour remain likely. The greatest
   freezing-rain rates should focus across a small part of
   central/eastern Kansas. Rates up to 0.10 inch/hour will be possible
   across this area.

   DISCUSSION...A broad area of precipitation is ongoing this morning
   across the southern/central Plains in association with strong
   low-level warm advection preceding a northeastward-moving shortwave
   trough. Some of this precipitation is occurring atop a shallow
   near-surface sub-freezing layer, which is supporting predominately
   freezing rain from parts of the TX Panhandle/western OK
   northeastward into much of central/eastern KS and western MO early
   this morning. The surface wetbulb freezing line similarly extends
   from southwest to northeast across west TX and much of OK. Numerous
   freezing rain reports have been observed across central/eastern KS
   in the past couple of hours. Freezing-rain rates around 0.05 inch
   per hour remain likely over much of this area based on recent
   observations. The strongest forcing for ascent should focus across
   parts of central/eastern KS through 15Z, where a relatively narrow
   corridor of greater freezing rain rates may occur. Up to 0.10 inch
   per hour rates appear possible across this area. Also, ice accretion
   may be enhanced with temperatures in the mid to upper 20s.

   With pronounced low-level warm advection expected to continue across
   central/eastern KS over the next several hours, surface temperatures
   will gradually warm above freezing from south to north across mainly
   southeastern KS. A transition from freezing rain to rain will
   likewise occur.
