Area Forecast Discussion
National Weather Service Omaha/Valley NE
245 PM CDT Thu Mar 30 2017

.SHORT TERM...(Tonight through Sunday)
Issued at 245 PM CDT Thu Mar 30 2017

Quiet but cloudy weather is expected tonight as a ridge of high
pressure prevails across the region. Low level moisture progs
suggest the low stratus will remain in place overnight, with slow
clearing on Friday. Low temps tonight should be in the mid 30s,
with highs on Friday a little warmer in the mid 50s.

The upper trough across the west coast will continue to deepen
into a closed low as it moves into the 4 corners region tomorrow.
Moisture and lift from this system reaches the area during the day
Saturday with increasing chances for rain, with pops eventually
rising into the 60-80% range Saturday night, with precip winding
down by Sunday afternoon. Instability mostly remains south of the
forecast area, but H85 computed lifted indices begin to go
slightly negative south of I80 late Saturday night through Sunday,
thus isolated thunderstorms will be possible.

.LONG TERM...(Sunday night through Thursday)
Issued at 245 PM CDT Thu Mar 30 2017

It should be dry Sunday night and Monday, but another strong
closed upper low moves out of the central Rockies, spreading
precip chances back into the area Tuesday into Wednesday when pops
increase to 60-80% once again. There is also limited instability
on Tuesday, thus isolated thunderstorms will be possible. Any
colder air associated with this should remain well to the west
across western and central NE. Precip moves east by Thursday.


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1209 PM CDT Thu Mar 30 2017

Radar mosaic showing pcpn activity will no longer be an issue
leaving only llvl cigs to contend with. Upper low currently
siting over ern KS will be relatively slow moving east thru
tonight. In the meantime...llvl moisture will continue wrapping
around into ern Neb resulting in persistent MVFR/IFR cigs pretty
much thru the fcst pd.
