.SHORT TERM...(This evening through Saturday night)
Issued at 237 PM CDT Fri Jul 5 2019

MCS that crossed the area overnight has weakened and shifted east of
the area this afternoon. A meso high has built in across the
forecast area in the wake of the system, and that is helping to keep
conditions stable. There has been some recovery across the Panhandle
due to moist southeast upslope low-level flow and partial sunshine.
Expect storms that are developing across the higher terrain to push
eastward into the Panhandle this evening. The Hi-Res model consensus
is to congeal the storms and dive them southeast through portions of
southwest Nebraska later this evening. This makes sense with
central/north central Nebraska recovering from earlier MCS. As far
as severe potential, overall shear profiles do support some stronger
storm potential. Damaging winds would be the main concern as the
storms dive southeast. We'll keep the highest pops south of I-80
tonight with lesser chances to the north/northeast.

Quite a bit in the way of cloud cover is expected Saturday, but
expect at least some destabilization of the atmosphere during the
afternoon. The better instability looks to reside across western
Nebraska and the Panhandle. Expect scattered storms to once again
initiate across the higher terrain of WY during the afternoon. These
storms will track east into the Panhandle and far western NE
Saturday evening. HRRR model shows some potential for development
across portions of northwest NE as well. This scenario is more
uncertain with the lack of a low-level boundary to focus
development. Effective shear is ample for at least some storm
organization.

.LONG TERM...(Sunday through Friday)
Issued at 237 PM CDT Fri Jul 5 2019

Upper ridging will remain across the Southern Plains through the
middle of next week. Meanwhile a strong shortwave will slowly move
east across southern Canada. General west to southwest flow aloft
can be expected across our region in between these two features.
Several weak pertubations within the flow will yield in scattered
thunderstorms from time to time. Hard to nail down the higher
chances at this point. Overall expect a decrease in pops as we
head toward the last of the week. Upper level ridging begins to
expand northward with highs in the upper 80s to near 90F by weeks
end. Mostly 80s can be expected the early to mid parts of the
week.
