Area Forecast Discussion
National Weather Service Omaha/Valley NE
1134 PM CDT Sun Apr 16 2017

.SHORT TERM...(Tonight through Wednesday)
Issued at 155 PM CDT Sun Apr 16 2017

A few scattered showers continue along the Nebraska/Kansas border
this afternoon but this activity should begin to push south of the
area this evening as surface high pressure builds southeast.
Otherwise, a surface boundary will extend northeast from an area
of low pressure over northeast Colorado into north central
Nebraska this evening as the surface high drifts east. All of the
CAMs develop precipitation along this front this evening and just
brushes the northwestern portion of our CWA. This will be
something to keep an eye on as we go through the evening.
Otherwise, the main thunderstorm activity this evening should be
well off to our south.

On Monday, strengthening low level warm air advection will be
underway across the Central Plains ahead of a rigorous shortwave
upper level trough moving east across eastern MT and into the
Dakotas. This should bring increasing moisture to our region as
well. An associated cold front will sweep through the
northern/central plains early Tuesday and provide the focus for
showers/tstms throughout the day Tuesday and into the evening
hours. This front is forecast to slow down and stall near the
Kansas/Nebraska border by 06Z Wednesday in broad southwesterly
upper level flow. This boundary is forecast to remain active
through the day Wednesday and could become quite active as
surface low pressure drifts into southeastern Nebraska by
Wednesday afternoon, pushing the front north of I-80.

.LONG TERM...(Wednesday night through Sunday)
Issued at 155 PM CDT Sun Apr 16 2017

By Wednesday evening, the front will drop southeast into Kansas
and Missouri as high pressure drops out of the Dakotas.

Next weekend, a deepening upper trough will dig across the
western US and dive southeast into the southern plains states.
This should leave much of our forecast area dry with slightly
cooler temperatures.
