What forecasters said that day

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

NWS Amarillo, TX wrote its last area forecast discussion before this winter storm warning went out at Apr 28, 12:27 AM CDT, 3 hours 53 minutes earlier.

Area forecast discussion, Apr 28, 12:27 AM CDT, 3 hours 53 minutes before
Area Forecast Discussion
National Weather Service Amarillo TX
1227 AM CDT Fri Apr 28 2017

.AVIATION...
VFR conditions will start the 06Z TAF period. However as we
progress toward the end of the TAF period, MVFR conditions will
be likely at all TAF sites. West and southwest winds throughout
the day will transition into a more north and northeasterly flow
as we go past 00Z Saturday. Winds throughout the day will be
between 15-20 kts with gusts over 25 kts at times. This will be
reduced to 10-15 kts after 00Z Saturday. Our next weather system
will be moving east-southeast across all TAF sites with
precipitation starting at KDHT/KGUY around 00Z and KAMA between 03
and 06Z. Accompanying the precipitation, the most pronounced
aviation hazard will be the lower cigs between 3.5-4.5 kft just
out ahead of the precipitation timing. MVFR conditions are likely
from around 00Z Saturday through to the end of the TAF period for
all TAF sites.

PREV DISCUSSION... /Issued 423 PM CDT Thu Apr 27 2017/

DISCUSSION...
A cold front will push across the Panhandles tonight before
stalling south of the forecast area. The frontal boundary is then
forecast to lift northward Friday and Friday night as a warm front
before a secondary surge of even much colder air drives the front
south again. Vigorous closed upper low will develop over the Great
Basin region Friday and then digs south and east near the Four
Corners region by late Friday and then into central and southeast
New Mexico Friday night and Saturday. The upper low is then
expected to lift northeast across the southern Texas Panhandle
Saturday night and Sunday. Convection will diminish this evening
and tonight before developing once again Friday afternoon and
Friday night. As 850 mb temps fall to at or below freezing in the
colder sector of the upper low Saturday and early Sunday, wintry
precipitation is expected to spread northwest to southeast across
much of the northwest half or two-thirds of the forecast area.

Some rain and snow mix or snow in the higher elevations of the
western Oklahoma Panhandle will be possible mainly late Friday
night into Saturday morning, however best chances are expected
Saturday night and early Sunday. Lots of uncertainties on timing
and track of the upper low resulting in low confidence on
snowfall accumulations and locations impacted. Feel best chances
will mainly be across the northern and western portions of the
Texas Panhandle as well as the western and possibly the central
Oklahoma Panhandle. Upper low lifts northeast across the central
Plains states by early next week as upper ridge builds across the
western states. Another northern stream shortwave trough will
track across the central Rockies by late Tuesday and approach the
Panhandles by next Wednesday. Chances for convection will increase
by the middle of next week with the approach of this upper trough
and as a backdoor cold front moves through the forecast area by
next Tuesday and Wednesday.
