Garrett’s Blog: Wednesday’s Winter Storm

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

The latest in a barrage of winter storms to affect the area will move in on Wednesday. Winter Storm Watches are already in effect. Upwards of 2-4″ of a snow/sleet mix will be possible with locally higher amounts in the Ozarks. The heaviest totals will be in North Central Arkansas. Roads are expected to become slick and slow again on Wednesday and could continue to be slick into Thursday. School and business cancellations are possible both days.

Here’s how the current timeline looks:

  • Tuesday 10pm: Heavy rain moving across the area
  • Wednesday 4am: Rain changing to sleet/freezing rain in Northwest Arkansas
  • Wednesday Noon: Snow in Northwest Arkansas, Rain changing to freezing rain and sleet in River Valley
  • Wednesday 5pm: Snow in Northwest Arkansas and River Valley
  • Wednesday 10pm: Snow moves out of area
  • Thursday 6am: Morning lows from 12-20º

As of this evening, the watch is only for Arkansas; however this may change and new data arrives late Monday and into Tuesday.

Probabilities for 1″ of snow are very high for our area. With temperatures that cold, it may only take 1″ for road problems to develop.

A Winter Storm Warning is normally issued for snows of 4″ or greater. This is one reason the watch is only for Arkansas at this time. This is the highest probability for 4″. Notice that it is highest in North Central Arkansas.

The transition from rain to freezing rain to sleet to snow will take place across the area on Wednesday. First in the north and then to the south. Look for a morning changeover in NWA and a midmorning/afternoon changeover in the River Valley. Right snow, accumulations should be in the 2-4″ range. On the low-end is we see more sleet. On the higher end if we see more snow. Either way, we’re in for another mess.
