.SHORT TERM...(This evening through Tuesday night)
Issued at 254 PM CDT Mon Jul 1 2019

Upper level ridging has flattened some and settling back over the
Southern Plains. This has allowed a stationary front that has been
located across South Dakota to sink south into Nebraska. The front
will be located from around O'Neill to North Platte to Imperial late
this afternoon. The front will weaken and remain in the area
Tuesday, then as upper ridging expands northward once again
Wednesday and Thursday, the front should lift north and become
stationary near the NE/SD border. The front will continue to be the
focus for scattered thunderstorm development the next several days.

As mentioned, the front is located from near O'Neill to North Platte
to Imperial. Scattered thunderstorms are expected to develop late
this afternoon and evening along and near the front. Hi-Res models
show portions of southwest Nebraska (along and south of I-80) having
the best chance for storm organization this evening. Appears a small
MCS could develop in this area and then track eastward into
southern/central Nebraska overnight. Otherwise the storms will tend
to be scattered...and with weak shear organized severe is not
expected. Strong outflow winds though will be possible along with
the potential for heavy rainfall. At this time not seeing a signal
for widespread heavy rain - but a line of thunderstorms could train
over the same location for a time right along the front. This seems
most likely to occur from portions of Hayes, Frontier into
southern/southeast Lincoln counties. The front will weaken and
become nearly diffuse on Tuesday. There is no clear focus for storm
development and will keep pops low. Highs will generally be in the
mid 80s with at least some cloud cover.

.LONG TERM...(Wednesday through Monday)
Issued at 254 PM CDT Mon Jul 1 2019

Upper level ridging will remain across the Southern Plains through
the upcoming week. It is forecasted to build northward some
Wednesday into Thursday. A nearly stationary front will refocus near
the NE/SD border. This would be the best area to see scattered
thunderstorm activity with slight chances farther south. Highs will
once again approach or exceed 90F as the ridge builds northward. Late
in the week and next weekend, it appears a leeward surface low will
become established across northeast CO, with moist southeast upslope
flow across the region. Mid-level flow remains fairly weak, but at
least scattered thunderstorms are possible across the region on the
northern periphery of Southern Plains upper level ridging. The best
chance looks to be Friday evening at this point when a short wave
crossing the area could enhance coverage. Temperature wise highs
look to mostly be in the 80s for the upcoming Holiday weekend.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 636 PM CDT Mon Jul 1 2019

Scattered thunderstorms developing across southwest through
central Nebraska will build into LBF within the next couple hours
and may bring brief MVFR conditions to the area. The strongest
storms in the region may contain strong wind gusts and hail.
Expect thunderstorms to slide east by late evening clearing the
area by 02/05z with VFR conditions then expected to end the
period.

.LBF WATCHES/WARNINGS/ADVISORIES...
