Area Forecast Discussion
National Weather Service North Platte NE
309 PM CDT Wed Jul 4 2018

.SHORT TERM...(This evening through Thursday)
Issued at 244 PM CDT Wed Jul 4 2018

The main forecast concern going into tonight will be the
development of strong to severe storms with heavy rainfall an
additional threat.

The 12Z LBF sounding showed a PWAT of 1.40 inches with a tap of
monsoonal moisture shown by the current GOES-R water vapor
channels. This is near the historic max for this day, thus the
concern for heavy rainfall and possible flooding.

The cold front currently extends from Oshkosh through Brewster to
Spencer and continues to slowly sag southward. Development is
forecast to occur along and behind this front, initially across
the northeast, building southwestward this evening. The storms
should form a broken to continuous line this evening while slowly
dropping southward overnight. A slight risk for severe storms is
forecast south a a line from Lewellen through Ainsworth and
Spencer. With thunderstorms expected to become fairly widespread
across this area, Forth of July activities are likely to be
impacted, with rain and thunderstorms slow to move out of the
area.

On Thursday, the front will stall out across northern Kansas into
southeast Wyoming. While early to mid morning may be fairly dry,
chances increase late morning into the afternoon, mainly south of
highway 2. With east to southeast winds and partly to mostly
cloudy skies, temperatures to range mainly in the lower 80s.

.LONG TERM...(Thursday night through Wednesday)
Issued at 244 PM CDT Wed Jul 4 2018

Shower and thunderstorm chances continue Thursday night across
southwest areas, as moisture and disturbances rotate out of
Colorado. Chances for showers and a few thunderstorms to linger
into Friday as the upper ridge center build west across Colorado
and Utah. Highs to range from the upper 80s west to the lower 80s
east. Then expecting dry conditions through Sunday, followed by a
slight chance far northwest Sunday night and again Tuesday night
into Wednesday. This will occur as an upper trough moves east
across the Pacific NW into the Northern Plains. Highs Saturday
through Wednesday return to the upper 80s to mid 90s.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 124 PM CDT Wed Jul 4 2018

development this afternoon and evening across most of southwest,
central and portions of north central Nebraska. Most likely the KLBF
TAF site will be impacted sometime this evening, with most if not
all of the activity staying southeast of the KVTN TAF site. Winds
will be variable and gusty near any thunderstorm activity, otherwise
should be less than 15 kt.
