Area forecast discussion, Jul 28, 2:24 AM MDT, 46 minutes before

Area Forecast Discussion
National Weather Service North Platte NE
324 AM CDT Sat Jul 28 2018

.SHORT TERM...(Today and tonight)
Issued at 323 AM CDT Sat Jul 28 2018

Rain and thunderstorms are expected to persist through Saturday. The
heaviest precipitation will be north of a line from Valentine to
Burwell. Total new rainfall will be between a half inch and one
inch. The cooler temperature trend will also continue into Saturday
with highs only rising into the low to mid 70s.

In addition to heavy rain, there is also a chance for severe weather
across southwest Nebraska on Saturday afternoon and evening. Current
SPC outlook has this area highlighted in a slight risk. Current
thinking is that storms will not arrive until late Saturday (after
7pm) and will just briefly impact portions of southwest Nebraska
before moving southeast. Any storms that develop will have the
potential to produce large hail, strong winds, and heavy rain.

.LONG TERM...(Sunday through Friday)
Issued at 323 AM CDT Sat Jul 28 2018

For Sunday, rain and thunderstorm chances continue as a series of
shortwaves move across Nebraska. Confidence in location of
thunderstorm impact is low with much of the forecast area expected
to be impacted. Heavy rain is not anticipated to be a major threat
on Sunday, however, hail and damaging winds could be possible in
some of the stronger storms. Details regarding this Sunday forecast
will become more certain over the next day.

A strong upper level ridge will build across the western US on
Sunday night. This ridge will allow surface high pressure to return
to the central US resulting in a return to drier weather through the
end of next week.

For temperatures...another cool day is in store for north central
Nebraska on Sunday with afternoon highs only rising into the low to
mid 70s. A gradual warming trend will return starting on Monday with
highs eventually rising back into the upper 80s to low 90s by next
Friday.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1142 PM CDT Fri Jul 27 2018

Ceilings will lower overnight across western and north central
Nebraska to 1000 to 2500 FT AGL for both the KLBF and KVTN
terminals. There will be a continued threat for thunderstorms
overnight across western and north central Nebraska with coverage
being isolated in nature. Will handle this with a VCTS mention for
both terminals overnight. Ceilings will increase on Saturday but
remain in the 3000 to 8000 FT AGL range for KVTN and the 3000 to
10000 FT AGL range for KLBF.

.LBF WATCHES/WARNINGS/ADVISORIES...
