Severe Thunderstorm Warning 143, NWS North Platte, NE

Area Forecast Discussion...UPDATED
National Weather Service North Platte NE
1218 AM CDT Sun Jul 7 2019

.SHORT TERM...(This evening through Sunday night)
Issued at 326 PM CDT Sat Jul 6 2019

Atmosphere again in recovery mode this afternoon in the wake of the
latest MCS that crossed the area last night. A weak surface low is
noted across north central Nebraska, with bands of stratocumulus
clouds in areas of weak convergence across the region. An isolated
weak thunderstorm could develop in one of those areas of weak
convergence, but the better threat of thunderstorms will come later
this evening and overnight. HRRR and several other Hi-Res HREF
members organize thunderstorms into a small complex across the
central and southern Panhandle early this evening. The storms then
track east across portions of the southern Sandhills and southwest
Nebraska late this evening and overnight. Some strong wind potential
with the cluster as well as locally heavy rainfall. Will carry a
swath of likely pops where the system is expected to track with 40
or less pops elsewhere. Similar set up on Sunday with southeast
moist low-level flow aiding in destabilization across the western
High Plains Sunday afternoon and evening. This should once again
lead to scattered afternoon thunderstorm development, with the
activity possibly moving into western Nebraska Sunday evening.
Otherwise southeast winds will increase Sunday as pressure falls
across the Western High Plains. Gusts up to 30 mph are possible
across portions of the Sandhills and north central Nebraska. The
increased wind will aid in better mixing with highs into the mid 80s
across western Nebraska.

.LONG TERM...(Monday through Saturday)
Issued at 326 PM CDT Sat Jul 6 2019

The start of the upcoming week will be unsettled. Upper level
ridging will be suppressed well south as an upper level trough moves
east across the Central and Northern Plains. This will lead to an
uptick in shower and thunderstorm chances Monday and Tuesday. By
the middle and latter parts of the week, GEFS and ECMWF build
upper level ridging into the four corners region and much of the
Central and Southern Plains. This will spread a warm layer aloft
across much of the region which will limit rain chances. Above
normal temperatures are also expected, with highs climbing into
the lower 90s by Friday and Saturday.

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1218 AM CDT Sun Jul 7 2019

Numerous thunderstorms will move through wrn and ncntl Nebraska
overnight and exit the region 10z-13z this morning. Scattered
thunderstorms are possible this afternoon and this evening, mainly
south of highway 20. Otherwise VFR is generally expected across
western and north central Nebraska Sunday and Sunday evening.
