... Widespread wintry mix expected 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 over far western Oklahoma...
and adjacent parts of North Texas... and also over far northern
Oklahoma. 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 numerical 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.
