Area Forecast Discussion...UPDATED
National Weather Service North Platte NE
622 PM CDT Wed Jul 5 2017

.SHORT TERM...(This evening through Thursday)
Issued at 336 PM CDT Wed Jul 5 2017

Latest water vapor imagery shows northwest mid-level flow aloft
across the Central High Plains as a upper-level ridge builds
across the western CONUS, stretching from the Four Corners region
into British Columbia and Alberta. Elsewhere, a weak shortwave
trough was moving across Saskatchewan into southwestern Manitoba.
Latest visible satellite shows cu developing across northern NEB,
NEB Panhandle, and southwest NEB. Of which, the cu field has been
most enhanced over the northern Sandhills into south central
NEB. Latest surface plot showed a broad surface low near eastern
MT/western ND with a central pressure near 1012 mb and a weak
trough extending south into the Central High Plains.

Rest of this afternoon-evening: There is at least a remote risk
for widely isolated thunderstorms. Best chances north of I-80 and
east of NE Highway 61, albeit with low confidence. Moderate
instability is expected (ranging MLCAPES 1000-2000 J/kg) across
the southeastern half of the CWA based on guidance/model soundings
with little-scant convective inhibition. Primary fly in the
ointment revolves around low-level forcing and strength of given
the uncertainty. Of which, any development is expected to diminish
this evening with the loss of daytime heating.

Another hot day tomorrow with most places outside of northwest NEB
expected to see highs 98-101 degrees. There is a risk for isolated
strong to briefly severe thunderstorms tomorrow afternoon and
evening. Some uncertainty involved with respect to coverage, but
isolated storms are the most likely.

.LONG TERM...(Thursday night through Wednesday)
Issued at 336 PM CDT Wed Jul 5 2017

Thursday night through Tuesday night...A ridge of High pressure
will remain in place over the western CONUS through early next
week giving us a mostly dry and warm air mass over the high
plains. That being said there are some isolated chances for
thunderstorms over the next several days however confidence in
thunderstorm development is low for most days with the exception
of Thursday evening into overnight. Although confidence is a
little better for Thursday evening/overnight, timing of
thunderstorm development is uncertain as models have discrepancies
in timing. Some models suggest development by late afternoon and
continuing through the evening hours and some suggest thunderstorm
development will take place after 00z. Tending to lean more to
late afternoon/evening development of storms as the main driving
force for initiation will be the weak cold front that moves across
Thursday late afternoon and evening in combination with strong
daytime heating.

After the front passes temperatures will cool slightly with highs
in the mid to upper 80s Friday and Saturday. Temperatures warm
back into the 90s Sunday through Tuesday.

&&

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 622 PM CDT Wed Jul 5 2017

The forecast uses the HRRR model but places the thunderstorms
about 60 miles or so west of the model. This follows the latest
radar trends which shows the thunderstorms developing southward
near highway 61, versus the model which shows the storms
developing in a southeast direction toward KVTN.

Storm activity, if it develops, could continue for several hours,
perhaps past midnight. The low level jet tonight should veer off
to the east toward morning and this will cause the storms to
dissipate, if not sooner.

.LBF WATCHES/WARNINGS/ADVISORIES...
None.
