Area Forecast Discussion
National Weather Service Omaha/Valley NE
702 AM CDT Thu Aug 17 2017

.SHORT TERM...(Today through Saturday)
Issued at 320 AM CDT Thu Aug 17 2017

Closed upper low over southwest Minnesota at 07Z will track
northeast toward the upper Great Lakes today with weak short wave
ridging moving into the region on the backside of the system.
This will provide the area with a short period of dry weather and
seasonal temperatures before the next upper wave comes into the
region tonight.

Another chance of showers and thunderstorms will accompany this
next system tonight, with the main threat of storms for the area
from late tonight into Friday morning. This next round of storms
is expected to be more progressive with less extensive
precipitable water forecast over the area, which should limit
widespread heavy rain compared to the previous Tue/Wed system.

Friday afternoon should see clearing conditions spread into the
area as another round of short wave ridging moves in behind the
departing trough. Dry weather will then continue for Friday night
through the day Saturday with temperatures warming a bit during
that time.

.LONG TERM...(Saturday night through Wednesday)
Issued at 320 AM CDT Thu Aug 17 2017

Pattern remains unsettled through much of the period with upper
flow becoming more amplified by Wednesday. At this time it looks
like the area will be under the influence of eastern trough by
then with a trend toward cooler temperatures.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 658 AM CDT Thu Aug 17 2017

VFR conditions are forecast through this evening with mainly clear
skies and west to northwest winds 10 to 15kt. Scattered
thunderstorms developing in western and central Nebraska this
evening are forecast to move east into eastern Nebraska after 06Z,
likely affecting KOFK between 08Z and 12Z, and perhaps KLNK and
KOMA after 10Z. Have mentioned VCTS in KOFK TAF but left out of
KOMA and KLNK until confidence of occurrence increases.
