Area Forecast Discussion
National Weather Service Omaha/Valley NE
1214 PM CDT TUE AUG 16 2016

.UPDATE...
Issued at 1215 PM CDT Tue Aug 16 2016

Updated grids and products earlier for showers and thunderstorms
that kept occurring in a band from west to east across the central
part of the forecast area. Coverage and intensity has been
decreasing the past hour or so. Recent experimental HRRR output
suggests some activity may linger in southeast Nebraska and
southwest Iowa this afternoon. Also a few storms may develop late
this afternoon or evening in the northwest part of northeast
Nebraska. Also updated sky cover...max temps and winds earlier.

&&

.SHORT TERM...(today through Thursday)
Issued at 300 AM CDT Tue Aug 16 2016

Although somewhat slower than previous nights models indicated,
scattered convection had developed and spread into northeast
Nebraska at 07z. Strong low level moisture transport is oriented
across eastern Nebraska early this morning with axis indicated to
spread slowly east through 12z then stall across extreme eastern
Nebraska into northwest Iowa during the morning. Better forcing
however shifts east of the area after 12z with showers and storms
expected to diminish. Some potential for additional storms return
again tonight as mid level instability remains across the area
and low level jet increases with eastern Nebraska western Iowa
border area located in best convergence area.

Generally dry and turning warmer for Wednesday into Thursday as
upper ridge amplifies a bit over the central plains and strong
upper trough approaches from the northwest.

.LONG TERM...(Thursday night through Monday)
Issued at 300 AM CDT Tue Aug 16 2016

Upper trough then works its way slowly southeast Thursday night
through Friday with surface system developing over eastern South
Dakota into western Nebraska. Increasing chance of storms for the
area late Friday afternoon into Friday night as front moves into
the area with potential for heavy rain. Will be interesting to see
how deeper moisture that has been in place across the south
interacts with this northern system. Models show upper trough
becoming fragmented by Saturday with one wave coming across the
region on Saturday while main energy stays to the west over the
northern Rockies before moving into the region on Sunday. This may
result in additional chance of more widespread rain for both
Saturday and Sunday. Everything then shifts south and east of the
area SUnday night and Monday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1215 PM CDT Tue Aug 16 2016

Generally look for VFR conditions through the period. Isolated
TSRA will be possible...mainly at KOMA between 03z and 09z. Winds
should become light and variable tonight. Some fog is possible
toward sunrise but did not mention in TAFs at this time.
