... Winter storm possible across the northern half of the four state
region this weekend...
A strong upper level storm system will approach the four state
region Saturday night into Sunday with winter precipitation
possible along and north of the Interstate 20 corridor of northeast
Texas and northern Louisiana... including southeast Oklahoma and
southern Arkansas. Precipitation will begin late Saturday afternoon
and evening as just rain in the west... but through evaporative
cooling... a mixture of rain... mixed with sleet and snow will be
possible late Saturday night. Sunday will be a cold and raw day
across the entire region. There should be enough cold air in place
for a sleet and snow mixture across southeast Oklahoma and
southern Arkansas... while further south near the Interstate 20
corridor of northeast Texas and northern Louisiana... a mixture of
rain... sleet and snow will all be possible. Precipitation should
turn into all snow across southern Arkansas and southeast Oklahoma
Sunday night while there will continue to be a mixture of sleet
and snow further south near Interstate 20 before the precipitation
tries to come to and end late Sunday night. Accumulating sleet and
snow will be possible with this winter storm this weekend...
especially across southeast Oklahoma and southern Arkansas. Snow
accumulations beginning late Saturday night... and continuing
through Sunday night... could total 2 to 4 inches with isolated
higher amounts across southeast Oklahoma and southern Arkansas.
Further south near the Interstate 20 corridor of northeast Texas
and northern Louisiana... slight accumulations of sleet and snow
will be possible through Sunday night.
Winter storm watches will likely be needed for at least the
northern portions of our region for late Saturday night through
Sunday night and this will likely be issued later this afternoon.
Uncertainty does exist as to just how far south winter precipitation
accumulation will be possible. Just a slight southward shift of this
storm system would result in higher sleet and snow accumulations...
further south along the Interstate 20 corridor. The progress of this
system will continue to be monitored over the next 24 to 48 hours.
Preparations for a winter storm... with accumulating sleet and or
snow... should be made for locations along and north of the Interstate
20 corridor by Saturday.
