The National Weather Service has issued a Winter Storm Watch for our area which will be in effect from Thursday Morning through Friday Afternoon.
A cold front is expected to enter Northwest Oklahoma this evening and pass through the State by mid-morning Thursday.
Significant amounts of snow, sleet, and freezing rain are expected over parts of Oklahoma. The main snow and sleet impacts are most likely to occur near and North of a line from Altus to Lawton to Shawnee.
Farther South and East, ice accumulation will be the main concern because of freezing rain.
The difference between whether well see snow, freezing rain, or sleet is whether or not there is a layer of warm air aloft. If there is no warm air layer then well get snow. If there is a warm layer, then the depth of the layer will determine the precipitation type. A shallow layer of warm air means sleet. A deep layer of warm air means freezing rain.
TIMING: There will be a brief round of freezing rain on Thursday morning through mid-afternoon with accumulations of .10 inches possible on bridges, overpasses, and protected surfaces expected. Probably similar to what we experienced in the winter storm that impacted us 2 weeks ago. The main wave of precipitation is forecasted to start around 9 or 10 PM Thursday night and end by mid-day Friday. For our area this will most likely be in the form of sleet possibly changing over to snow by the end of the storm.
Temperatures are not expected to get above freezing until early next week.
MAIN IMPACT: Dangerous driving and walking conditions will result from accumulation of sleet. Travel impacts will be more widespread than with the previous storm.
OTHER IMPACTS: Ice accumulation in the freezing rain area and possibly in the sleet accumulation area may cause power outages and tree damage.
PRECAUTIONARY/PREPAREDNESS ACTIONS. Plan now for travel impacts and keep up with the latest weather information.
