Winter Weather Update - Sunday February 14th- 7:30 AM

Here are updated forecast graphics for the winter storm tonight and cold weather Monday night.






Changes from previous update:

  • Winter Storm Warnings and Winter Weather Advisories were issued.

  • Hard Freeze Watch in effect for Monday Night

  • Wind Chill Watch in effect for Monday Night

  • Ice Accumulation values were increased.


WHAT: Accumulating ice (freezing rain) and possibly sleet; followed by frigid cold.

WHEN:Accumulating ice/sleet is most likely late tonight through Monday. The coldest night this week will be Monday Night. Freezing Rain will begin in the northwestern parishes/counties shortly after midnight and spread east-southeast. A more detailed timing graphic will be sent later this morning.

WHERE: Accumulating ice is most likely across the northwestern half of the area. A Hard Freeze is likely for the entire area.


  • We are very confident there will be ice accumulation in northwestern portions of the forecast area. Confidence in accumulation drops significantly the farther southeast a location is. We are less confident in how much of the ice will be in the form of freezing rain vs sleet.
  • We are very confident in the occurrence of very cold temperatures Monday night/Tuesday morning.

Potential Impacts: 

Ice and Snow Accumulation:

  • Ice accumulation up to about 0.50 inches is currently forecast across northwestern areas. Ice accumulation drops off as you move southeast. See the graphics for a better description of these areas.
  • Sleet is possible in parts of the area and will be a half an inch or less.
  • Accumulation of sleet/ice will result in dangerous travel conditions Monday morning and Tuesday morning. Any remaining liquid Monday night will freeze with the cold temperatures and create a slick Tuesday morning commute.
  • Impacts could linger through Tuesday night as temperatures across northwestern areas struggle to rise above freezing during the day Tuesday.

Freeze/Hard Freeze:

  • Hard freeze conditions are expected across the area.

  • Hard freeze conditions could result in significant damage to unprotected pipes as well as citrus and other sensitive agricultural crops.
