Winter starts this evening

5:38 p.m. Winter Solstice, the start of winter


FYI: For those traveling toward north central, northeast and east central Kansas, Thursday into Friday, National Weather Service, Topeka, Kan.

Expected Weather:A mixture of rain and freezing rain will be possible during

 the early afternoon hours on Thursday before mixing with and

 changing to snow Thursday night.  The chance for light snow will

end on Friday. At this time, 2 to 4 inches of snow is expected

over the area.

Areas Affected:  All of north central, northeast, and

 east central Kansas.

Timing: Precipitation will begin during the late morning on Thursday

and continue through the evening…before diminishing on Friday.  

The precipitation may begin as a mixture of sleet and snow for

north central Kansas with freezing rain and/or sleet for

northeast and east central Kansas. Changeover to all snow

will occur during the late hours on Thursday.

Expected Accumulations:  Light ice accumulations will be

possible Thursday and Thursday night. There is a potential

 for two to four inches of snow on Thursday night into early

 Friday; however this may increase based on the evolution

of the storm system. Locally higher amounts are possible

depending on the timing of the transition to snow. 

Wind and Temperatures:  Temperatures in the 30s

Thursday will fall into the 20s Thursday night.

 Gusty north winds of 20 to 30 mph will develop

 late Thursday night and persist into Friday. 

Potential Impacts
This round of winter weather will be affecting the

 area during a period of heavy holiday travel. 

 If the storm system is able to come together over

 the area, roadways will become slick with

hazardous driving conditions as early as noon on

 Thursday.  Some blowing and drifting snow

will be possible late Thursday night

and Friday.  Plan your travel accordingly,

 and allow extra time should road conditions deteriorate.

 
Weather Discussion
  A strong storm system will emerge from

the Rockies on Thursday, bringing the potential for

 widespread precipitation to much of the

 central and southern Plains.  A mix of

freezing rain, sleet, and snow will be

 possible across the local area. The storm system

will move east of the region during the day on Friday.
