Area Forecast Discussion
National Weather Service Omaha/Valley NE
533 AM CST Wed Jan 17 2018

.SHORT TERM...(Today through Friday)
Issued at 300 AM CST Wed Jan 17 2018

Let the warmup begin! Temperatures will be the primary focus in
the short term forecast with dry weather during the period.

Surface high pressure was centered over the southern plains at 08Z
with a ridge axis into the upper Mississippi Valley. Light
southwest winds were already indicated in observations over the
region with steady or slowly rising temperatures. Winds are
expected to continue to gradually increase through the morning and
into the afternoon with temperatures reaching the 30s in most of
eastern Nebraska as the high drifts toward the lower Mississippi
Valley. Slightly cooler temperatures in the mid to upper 20s will
linger in southwest Iowa. The warming trend is expected to pickup
significantly across all of the area for Thursday into Friday as
an upper ridge moves across the region followed by stronger
westerly flow aloft. Although highs won`t reach record territory,
it will feel a lot better than the bitter cold of the past
several days.

.LONG TERM...(Friday night through Tuesday)
Issued at 300 AM CST Wed Jan 17 2018

Temperatures turn cooler and the weather pattern becomes more
active as we head into the weekend. ECMWF and GFS show a similar
trend in bringing a storm system out of the southern Rockies and
into the central plains late Saturday night into Sunday, although
timing of the surface features differ between the models with the
GFS taking a faster track with its surface low into eastern Iowa.
Precipitation looks to be rather messy with this system with
temperatures on Sunday starting out above freezing in most of the
area before turning colder Sunday night. The potential for
significant snow in parts of the area still looks possible for
late Sunday into Monday depending on the choice of model, but
still too far out for specifics at this time. Mainly dry beyond
Monday with no sharply colder air in sight at this time.
