Area Forecast Discussion
National Weather Service Omaha/Valley NE
1150 AM CST Wed Jan 18 2017

.SHORT TERM...(today through Friday)
Issued at 300 AM CST Wed Jan 18 2017

Upper level pattern is expected to remain very active during both
the short and long term as a series of systems track across the
region in fast westerly flow.

Clear skies covered most of the forecast area early this morning
with extensive cloud cover located east and south of the area.
Some patchy fog possible in a few locations through mid morning,
mainly in southwest Iowa and portions of southeast Nebraska where
winds are light to calm. Mainly sunny conditions are expected to
develop during the morning but clouds will be on the increase late
this afternoon and tonight as an upper level system lifts out of
the southern Rockies and into the central plains region. This
system then continues to intensify over the area on Thursday
before lifting northeast toward the upper midwest and lower Great
Lakes Thursday night and Friday. Another system follows quickly on
the heels of the first on Friday, moving out of the central
Rockies and over Kansas and Nebraska.

Both of these systems will bring another prolonged period of
cloudy and damp weather to the area with some chance of drizzle
or light rain from Thursday morning through Friday. The one
positive factor during this time is that temperatures will remain
above normal, keeping the chance of freezing precipitation to a
minimum.

.LONG TERM...(Friday night through Tuesday)
Issued at 300 AM CST Wed Jan 18 2017

There will be a better chance of rain Friday night into Saturday
as the central Rockies system lifts north across the region
toward the upper midwest. Temperatures are expected to still remain
above normal during this time with rain again the primary
precipitation type.

Above normal temperatures continue through the weekend and into
early next week with dry weather expected as the region is
forecast to stay north of another strong fast moving system
coming out of the southern Rockies and across the southern plains
on Saturday and Sunday. Short wave ridging will move over the
region on Monday in advance of yet another broad trough coming
across the southern Rockies. this system will bring an increasing
chance of rain or snow to the region on Tuesday as temperatures
begin to trend a bit cooler.
