The National Weather Service, Norman Forecast Office’s
“Area forecast discussion”:
“The remainder of the day will feature clouds…lots of them…and
cold. Despite southeast winds…residual snow cover and cloudiness
have prevented most areas from climbing out of the 20s and 30s.
Things should stay fairly quiet through the first half of the
evening…that will change quickly later tonight.
“Expect snow or a mixture of snow…some sleet and
freezing drizzle to move into far western Oklahoma and western
north Texas by 10 p.m. In keeping with yesterday’s event…it’s
looking as though precip type will transition over to snow fairly
quickly as the depth of subfreezing air deepens. This will happen
first over northwestern Oklahoma…where heavy snow will develop
by midnight and spread eastward overnight into tuesday. A bit
farther south…light snow will develop and move along the Interstate-44
corridor through the day on tuesday. The forecast is a bit tricky
with this system due in part to the dreaded dry slot which will
mean a tight gradient in storm total snowfall across the region.
Areas where more mid level dry air is present may see virtually
nothing aside from a light freezing drizzle or light freezing rain
and a few flurries. Right now this area looks to mostly remain
south of Interstate-44. Substantial snow accumulations in the 7 to 10 inch
range seem probable over extreme north central Oklahoma with 4 to
6 inches over a large part of northern Oklahoma. This will mean
treacherous to nearly impossible travel conditions in these
areas…and travel is strong discouraged by tomorrow morning. Snow
amounts from southwestern Oklahoma up through the Oklahoma City metro should
fall in the 1 to 3 inch range for the most part. Slick roads will
be likely over these areas by late Tuesday morning…but the
higher impacts should remain well to the north.
“Once we get past this winter storm…bitterly cold air will surge
southward. Highs both Wednesday and Thursday will largely be
driven by snowpack over northern Oklahoma…but right now guidance
suggests lower teens to upper single digits for the northern third
of Oklahoma. The remainder of Oklahoma and western north Texas
will see highs ranging from the low teens to low 20s. wind chills
will be well below zero both days.
“It seems the weather pattern has become a bit of a broken record
as another chance of snow will enter the picture on
Thursday…then again on Saturday and Sunday. By this time…the
depth of cold air should be such that all snow is anticipated.
beyond the weekend…a modest warm up and drier conditions are
