What forecasters said that day

The local office's own words before this wind chill advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before this wind chill advisory went out at Dec 30, 2:28 PM CST, 28 minutes earlier.

Area forecast discussion, Dec 30, 2:28 PM CST, 28 minutes before
Area Forecast Discussion
National Weather Service Tulsa OK
228 PM CST Sat Dec 30 2017

.DISCUSSION...
Main forecast issues continue to focus on light wintry
precipitation chances through tonight and the bitterly cold wind
chills tonight and especially New Year's Eve.

The initial push of Arctic air has moved through the area with
only far southeast OK into western AR remaining a bit above
freezing. Radar/surface obs and reports have shown intermittent
freezing drizzle and a bit of snow through the day so far,
although the intensity has remained very light. Near term guidance
continues to show a modest signal of continued light wintry
precipitation (primarily -fzdz) into the overnight hours mainly
across southeast OK into western AR. Should any of this pick up in
intensity, slick roads could quickly develop so will err on the
cautious side and issue a winter weather advisory for far
southeast OK for late afternoon through tonight. The advisory may
need to be expanded in coverage, and will defer this to the
evening shift.

Will also hoist a wind chill advisory for parts of northeast OK
tonight with overnight values expected to dip to around -5F to
-10F. A secondary surge of Arctic air will spill south tonight,
with high temperatures tomorrow only struggling into the 20s for
most areas. Dangerously cold wind chills will develop Sunday
night, with values ranging from -5F across southeast OK into
western AR to near -20F along the KS border.

Another very cold night expected Monday night as surface ridge
axis passes overhead and winds die off. Temperatures should
eventually rise above 32F by Wednesday brief return flow returns.
Another glancing blow of cold air arrives Wednesday night, but
nothing like we're seeing now.

...DANGEROUS WIND CHILL AND LIGHT WINTRY MIX THIS WEEKEND...

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

WINTER WEATHER.
	SNOW ACCUMULATION.
	RISK...Limited.
	AREA...Southeast and East Central Oklahoma and Northwest Arkansas.
	ONSET...Ongoing and then again late tonight.

	ICE ACCUMULATION.
	RISK...Limited.
	AREA...East Central and Southeast Oklahoam and Northwest Arkansas.
	ONSET...Ongoing and then again late tonight.

	WIND CHILL.
	RISK...Elevated.
	AREA...Northeast Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

FIRE WEATHER DANGER.
	RISK...Limited.
	AREA...Northeast Oklahoma and far Northwest Arkansas.
	ONSET...Ongoing.

DISCUSSION...
The leading edge of an arctic air mass has spread south into
southeastern Oklahoma and west central Arkansas this afternoon. Gusty
north wind and much colder temperatures have settled across
northeastern and east central Oklahoma as well as northwestern
Arkansas. Some light freezing rain or snow flurries will be possible
this afternoon and then again late tonight as another surge of cold
air spreads into the area. While mostly trace amounts are expected,
there may be just enough accumulation on some roadways to cause a few
slick spots.

Wind chill values in the single digits are occurring across Oklahoma
along and west of I-44. Wind chill readings will fall overnight
across the area with values by Sunday morning ranging from 10 degrees
below zero along the Kansas border to near zero in far northwestern
Arkansas to the teens near the Red River.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Winter Weather Potential...Dangerous Wind Chill Potential.
MONDAY and TUESDAY...Dangerous Wind Chill Potential.
WEDNESDAY through FRIDAY...No Hazards.

EXTENDED DISCUSSION...
Dangerous wind chills will continue into Tuesday as the arctic air
mass remains entrenched over the region into the new year. The
lowest readings are likely the morning of New Year's Day, with
values ranging from zero in far southeast Oklahoma and west-central
Arkansas to around 15 degrees below zero in northeast Oklahoma and
northwest Arkansas.

Additional light freezing drizzle or snow flurries will remain possible
through Sunday morning mainly south of Interstate 40. Amounts are
expected to remain very light, but given the cold temperatures, any
accumulation at all will lead to localized travel problems.

Those planning travel of any distance this holiday weekend should be
sure to take along a winter safety kit in case you experience trouble
in the bitter cold.
