.PREV DISCUSSION... /Issued 330 AM CST Sun Feb 25 2018/

DISCUSSION...
Clear skies combined with saturated ground and light winds this
morning has resulted in localized fog and freezing fog across
parts of northeast Oklahoma and northwest Arkansas. Will monitor
observations right up to zone issuance and decide on any mention
for the first few hours of the first period. Otherwise,
temperatures to warm up nicely for the afternoon. Another upper
trough to enter eastern Oklahoma late this afternoon or early
evening, however limited moisture in place will likely limit
impacts to increased cloud cover. A few sprinkles are possible
across northeast Oklahoma this evening, however will not include
pops for this evening at this time. Settled conditions to
continue into Tuesday, however moisture return will ensue and
along with increasing chances for showers from south to north
during the day. Upper system to move on shore from the southern CA
coast Tuesday evening, and approach the plains Wednesday. Highest
shower and storm chances this forecast cycle will accompany this
feature Wednesday before it lifts off to the northeast Wednesday
night. Dry conditions are expected for the rest of the work week,
and at least into the first part of the weekend. The persistent
west to southwest upper flow will aid in keeping afternoon
temperatures near or above seasonal averages throughout the week.
