.PREV DISCUSSION...(ISSUED 334 PM CST Wed Feb 17 2021)
SHORT TERM...Tonight Through Friday
A strong upper low pressure system continues in southern Canada with
a short wave in the Plains. This trough will continue moving east
tonight and through Arkansas Friday.

Snow continues across the southeast half of the area at this
time. Radar showed heavy snow in the Pine Bluff, Rison, and Star
City areas. The heavy snow is expected to continue through this
evening. The snow will slowly diminish after midnight. Some areas
will see an additional 4 to 6 inches this afternoon and tonight. The
Winter Storm Warning continues into Thursday morning. Travel will be
dangerous to impossible in the southeast half of the state
especially. Snow may also mix with sleet at times in the southeast.

The cold will continue through Friday. Single digit wind chills are
expected in the north Thursday morning. Lows will be in the teens
and 20s tonight and single digits and teens Thursday night. High
temperatures will be in the mid 20s to mid 30s Thursday and upper
20s to mid 30s Friday.

LONG TERM...Friday Night Through Wednesday
Dry conditions are expected Friday night through early Sunday, with
NW flow aloft and surface high pressure expanding across the
southern Plains. High pressure will shifts eastward through the end
of the weekend, while an upper trough quickly moves across the
central/southern Plains. A storm system will develop near the SE CO/TX
Panhandle and move across the state, bringing chances for rain and
brief periods of a rain/snow mix Sunday night through Monday morning.
The wintry mix will be short-lived and no significant impacts are
expected. The system will exit early Monday and high pressure will
follow, with dry conditions expected through the end of the period.

Forecast high temperatures will increase from the upper 30s and
lower 40s Saturday afternoon to the mid 50s and lower 60s by the
middle of the week. Lows will start out Saturday morning in the mid
to upper teens and increase to the upper 20s by Monday morning, up
to the mid and upper 30s by the middle of the week.

This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Tonight

Snow will continue through this evening before tapering off from the
southwest. The snow, heavy at times, will be confined mainly to the
southeast half of Arkansas. Some sleet and freezing rain will mix
with the snow in the far southeast.

Snowfall rates up to two inches per hour will be noted in places,
especially in the southern counties. This is where accumulations
could exceed a foot at some locations. Otherwise, amounts from four
to ten inches will be common.

Roads are already snow covered and hazardous, and travel is not
advised. Whiteout conditions at times and darkness will make driving
even more dangerous. People are asked to stay off roads to allow
crews to treat and clear the pavement.

In the south, new additional snow plus snow that fell a couple of
days ago may create enough weight to compromise roofs on some
structures. This includes roofs on homes and businesses, barns,
sheds, and chicken houses.

.DAYS TWO THROUGH SEVEN...Thursday Through Tuesday

While snow will remain in the forecast through early Thursday
afternoon, additional snowfall amounts will remain generally less
than an inch for most areas on Thursday.

Expect this storm system to move out of the region by Thursday
night. However, temperatures will remain well below normal through
Friday, with lows in the single digits and teens by Friday morning.

There may be some light wintry weather across portions of the area
Sunday afternoon into Sunday night. However, no significant impacts
are expected at this time.

.Spotter Information Statement...

Spotter activation will not be needed.
