SPRINGFIELD, Mo. -- The National Weather Service upgraded the Winter Storm Watch to a Winter Storm Warning for Wednesday night and Thursday.  The warning for snow, sleet and freezing rain will be in effect from 6 p.m. Wednesday to 6 p.m. Thursday.  You can track the latest watches and warnings here.

Here's the forecast from Brandon Beck on Wednesday morning:

Cloud cover will quickly increase today, and within east wind are temperatures will stay in the thirties.  There is a large area of precipitation moving northeast across Oklahoma and Texas.  However our very dry air will likely fight this off with most locations staying dry through the day.

The exception may be Northwest Arkansas and extreme southwest Missouri, where a few showers will occur later this afternoon.  Lift will increase later on this evening with a wintry mix overspreading at least western Missouri and Arkansas later tonight. I think the amounts will be relatively light, but enough to make roadways slick by Thursday morning.

The main show will come on Thursday.Very strong lift will create heavy precipitation through the day.  The forecast thermal structure in the lowest several thousand feet of the atmosphere suggests the best chance of freezing rain will be over Northern Arkansas, where an ice storm warning is in effect Thursday.  With northward extent that warm layer is expected to be a bit more shallow, making sleet the more predominant precipitation type.

Some snow is also possible, particularly over Central Missouri.  A winter storm warning begins tonight for all of our Missouri counties.  Road temperatures will be cold enough that whatever falls will stick around, so travel will definitely be impacted.

In addition wind gusts around 40 mph will be likely on Thursday, increasing the odds of spotty power outages where freezing rain occurs.  Again, this is most likely over northern Arkansas.
