... Widespread wintry mix expected late Sunday through early Monday...
Very cold air... which will spread over Oklahoma and western North
Texas early this weekend... will lead to a chance of ice and snow
when a storm system arrives late this weekend. Beginning late Sunday
and continuing through Monday... this storm system will pull
relatively warm and moist air up over the cold air entrenched at the
surface. Although this process will help modify and erode the colder
air... the atmosphere will warm fastest aloft. This will lead to a
mixture of snow... sleet... and freezing rain over much of Oklahoma
and western North Texas.
Precipitation is expected to begin as early as Sunday afternoon
across western North Texas and western Oklahoma... and then spread
northeast. It currently appears that precipitation will start as
snow... then transition to a mixture of sleet and freezing rain
Sunday night... before switching to rain on Monday. The greatest
chance of accumulating snow is forecast to occur with an area of
snow that is expected to develop over far western Oklahoma... and
adjacent parts of North Texas Sunday afternoon and then move
northeast toward north central Oklahoma Sunday night. The greatest
chance of sleet and snow will occur from near Wichita Falls up
through Oklahoma City. The greatest chance for freezing rain will be
over south-central and southeast Oklahoma. Current model forecasts
suggest that accumulations will be relatively light and should not
cause significant disruptions to travel or power supplies.
However... with it being quite cold initially on Sunday and Sunday
night... it will not take much precipitation to create slick and
hazardous bridges... overpasses... and sidewalks.
