Area Forecast Discussion
National Weather Service North Platte NE
341 AM CDT Sat May 27 2017

.SHORT TERM...(Today and tonight)
Issued at 335 AM CDT Sat May 27 2017

Timing tools suggest the area of rain on radar is moving east at 40
mph and will exit Ncntl Neb around 8 or 9 am. The blend of the RAP
and HRRR models keeps a likely POP in place for a few hours this
morning and isolated POP this afternoon. The afternoon rain chance
is the result of cold air aloft and the morning POP could be too
generous. The forecast rain chances this morning are under review
and may be updated depending on the eastward progress of the rain
shown on radar.

The temperature forecast uses the same blend listed above plus bias
correction for highs in the 60s. The RAP model shows h700mb
temperatures falling to around 0C by late afternoon and this will
keep skies cloudy with isolated shower activity.

Skies clear out tonight with Pacific high pressure building through
the Rockies. A blend of guidance plus bias correction suggested lows
in the 40s and near 40 across the Wrn Sandhills.

.LONG TERM...(Sunday through Friday)
Issued at 335 AM CDT Sat May 27 2017

Sunday through Wednesday An upper level low will move down from
Canada and continue to move east across the Great Lakes Region
through mid-week. High pressure then begins to build in from the
west.

The next chance for precipitation comes on Thursday with a weak
shortwave. Flow will become more zonal on Friday and Saturday, then
northwest flow returns on Saturday night and Sunday. Cooler
temperatures continue through the week into next weekend with highs
in the mid 70s, which is slightly below normal.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1126 PM CDT Fri May 26 2017

Local radar shows rain showers occurring across portions of
southwest NEB, eastern NEB Panhandle, and the western Sandhills
with embedded thunderstorms in Garden and Arthur counties.
Showers (and possible isolated thunderstorms from the
southwestern Sandhills on south) will continue and fill in
overnight across western NEB and spread into north central NEB
through the small hours. Precipitation chances continue into
tomorrow morning with chances then diminishing in the afternoon.

Ceilings are expected to deteriorate sub-VFR during the small
hours late tonight across western NEB. Current thinking is both
KVTN and KLBF terminals will be impacted by sub-VFR ceilings
beginning in the early morning with conditions improving late
morning/early afternoon.
