Area Forecast Discussion
National Weather Service North Platte NE
301 PM CDT Fri Jul 26 2019

.SHORT TERM...(This evening through Saturday night)
Issued at 251 PM CDT Fri Jul 26 2019

Latest day cloud phase distinction RGB and surface obs show a few
boundaries/lines of forcing. Notably from Box Butte to northern
Garden county to northern Arthur county, another then along the
southern part of the Cheyenne Ridge where there is a more of a
thermal gradient. Former the main concern wherein it has evolved
from shallow cumulus to towering cumulus with glaciation. Isolated
thunderstorms have developed there in the last 20 minutes with
lightning now detected via ENTLN and NLDN. Current thinking is
isolated-widely scattered thunderstorms and/or a small cluster
will evolve into early evening and affect mainly the eastern
Panhandle to northwest NEB-west central NEB and far southwest NEB.
A strong or briefly severe thunderstorm possible, but thinking
this threat will be isolated in nature. Note, storms that can move
southeast will see better instability and moisture, wherein dew
points exist in the upper 60s to lower 70s across central
Sandhills and parts of southwest NE. Otherwise, a localized heavy
rain threat exist due to storms regenerating across the previously
mentioned line of forcing mainly from northern Garden-Grant-
Arthur-McPherson. and storms regenerating and tracking across the
same area across eastern Panhandle-west central NEB.

Another round of activity is then expected tomorrow afternoon and
tomorrow night, albeit with somewhat better coverage of storms
expected. A weak frontal boundary will lie generally west to east
across the Sandhills with scattered to numerous storms possible
across northern Nebraska.

.LONG TERM...(Sunday through Friday)
Issued at 251 PM CDT Fri Jul 26 2019

The synoptic pattern early Sunday consists of an upper-level
trough across the Northern High Plains towards the Northern
Rockies, ahead a shortwave trough across SD-NEB, and a broad ridge
extending from southern CA and Baja California across the Pacific
Northwest. Meantime, a surface cold front is expected to be
positioned roughly southwest to northeast across portion of
southwest and north central NEB advancing eastward. 500 hPa height
rises will be spreading northward and eastward as the upper-level
trough advances into western Ontario Sunday to Sunday night.
Meanwhile, the aforementioned front will advance into eastern NEB
by late Sunday. Overall, shower and thunder chances will be
decreasing across western NEB through Sunday with the main threat
lingering/existing across mainly north central NEB. Of which, the
airmass will be moist across north central NEB with surface dew
points in the mid to upper 60s, albeit with so-so wind shear
generally 25-30 kts. Under northwest flow late Sunday night,
cooler and drier air will move in through early Monday. This will
be conducive for highs to be near to a few degrees before normal,
about 80 into the mid 80s. The ridge will then see a little shift
eastward with it then expected to be positioned Monday-Monday
night from the Four Corners to across the Canadian Prairies. A
weak disturbance embedded with the flow rounding the upper high
will bring low-end chances Monday night.

Tuesday and beyond, the amplified upper-level ridge will continue
to persist and will evolve and build eastward extending from the
Southern High Plains to across the Canadian Prairies by
Wednesday. Main sensible weather impacts Tuesday-Thursday appear
to be spotty- isolated thunderstorm chances Tuesday and isolated-
scattered thunderstorms Thursday. While there are some apparent
differences in phase and amplitude, a shortwave trough rounding
the ridge is anticipated to be moving round the ridge and
increasing chances across the area. Otherwise, highs will largely
be seasonable and near-normal, generally 80s to lower 90s.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1203 AM CDT Fri Jul 26 2019

Thunderstorms will be possible in the vicinity of the KVTN
terminal through around 2 PM CDT this afternoon. Storms will end
for the remainder of the afternoon. By late afternoon, the threat
for isolated storms will increase in west central Nebraska. The
threat for storms will persist into the evening hours, ending
overnight. Storms will be disorganized and highly isolated. That
being said, will leave out a mention of storms in the 18z KLBF and
KVTN TAF's.
