Area forecast discussion, Jul 10, 12:14 AM CDT, 2 hours 3 minutes before
Area Forecast Discussion...UPDATED
National Weather Service North Platte NE
1214 AM CDT Wed Jul 10 2019

.SHORT TERM...(This evening through Wednesday night)
Issued at 246 PM CDT Tue Jul 9 2019

A strong shortwave with a closed circulation noted at H5 and H7 was
located across far western ND this afternoon. An area of strong
winds aloft were spreading eastward across the region to the south
of the system. At the surface, a cold front has crossed the area
with west to northwest winds and drier air working into the region.
Despite the drier air and cold frontal passage, scattered
thunderstorms are expected to move across western and north central
Nebraska this evening. Storms will initiate across the higher
terrain of WY this afternoon and then track east/southeast. The
strong winds aloft will aid in storm organization, and while storms
overall should remain isolated to scattered, modest CAPE combined
with the strong winds aloft could yield a couple of high based super
cells. This evening a small quick moving line could evolve from the
supercells and pose a damaging wind threat. Any storms should exit
the area by sunrise Wednesday. The drier air moving in will help
cool lows some, with lower 50s expected across Sheridan county.
Upper 50s to lower 60s are anticipated elsewhere.

Surface low pressure will move across the Northern Plains Wednesday.
Northwest winds will increase across the area as a result. Model
sounding show a well mixed boundary layer and gusts of 30 mph or so
are expected across northern Nebraska, peaking about midday.
Otherwise wall to wall sunshine with fry air aloft overhead. Highs
will be seasonably mild, generally near 80 to the mid 80s.

.LONG TERM...(Thursday through Tuesday)
Issued at 246 PM CDT Tue Jul 9 2019

Warmer and drier weather is expected the middle and end of the work
week. The 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 the region which will limit
rain chances. The upper ridge will flatten just a bit Friday night
into the weekend, which will allow for a couple of weak disturbances
to migrate eastward across the region brining isolated to scattered
thunderstorm chances.

Above normal temperatures are expected with highs climbing into the
lower 90s Thursday through the weekend. The Climate Prediction
Center continues to forecast above normal temperatures and below
normal precipitation for both the 6 to 10 and 8 to 14 day outlook.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1214 AM CDT Wed Jul 10 2019

Scattered to numerous shower and thunderstorm coverage is expected
south of highway 2 until 12z this morning. Storm activity is
expected to progress south and east overnight. Thereafter, VFR
is expected throughout wrn and ncntl Nebraska from 12z Wednesday
to 06z Wednesday evening.
