Area Forecast Discussion
National Weather Service Omaha/Valley NE
1258 PM CDT Fri Apr 21 2017

.SHORT TERM...(Today through Sunday)
Issued at 313 AM CDT Fri Apr 21 2017

Quiet and slightly cool weather on tap for today as an upper
trough across the Rockies moves onto the central Plains. The KS/NE
border region will be on the northern edge of any precipitation,
thus will have a slight chance of showers there, but dry
elsewhere. Highs today just below normal in the lower 60s, with
partly to mostly cloudy skies.

High pressure prevails tomorrow with more sunshine, and temps a
couple of degrees higher than today.

Return southerly flow develops Sunday, with breezy southwest winds
expected, but with abundant sunshine. Highs Sunday around 70.

.LONG TERM...(Sunday night through Thursday)
Issued at 313 AM CDT Fri Apr 21 2017

Quiet, mild, and windy weather continues early in the long term,
although there will be a trough moving through the northern
Plains, which does push a surface cold front into the area. This
could bring a few showers to the NE/SD border area, but temps
Monday will be well above normal in the lower to mid 70s. With the
cool front there should be an increasing chance for showers Tuesday,
but instability remains south of the region across KS and MO.
Showers chances exist Wednesday as moisture moves out of the
Rockies. Easterly surface winds prevail, thus helping to keep
instability south of the region, and also helping to keep temps
just below normal in the upper 50s to mid 60s. Upper trough
begins to eject onto the Plains on Thursday, which should bring
instability with it. Showers and thunderstorms become likely
thursday across southern half of the forecast area.


.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1246 PM CDT Fri Apr 21 2017

Extensive layer of high clouds cover eastern Nebraska and western
Iowa at the start of the period. Dry easterly flow at the surface
through the mid levels are indicated by RAP forecast soundings to
extend into the overnight hours. This will allow VFR cigs to prevail
through the period as slow moving upper trough over the southern
plains works east and surface high pressure remains across the
upper Mississippi Valley.
