Area forecast discussion, Jul 8, 2:37 PM CDT, 1 hour 48 minutes before

Area Forecast Discussion
National Weather Service North Platte NE
237 PM CDT Sat Jul 8 2017

.SHORT TERM...(This evening through Sunday)
Issued at 236 PM CDT Sat Jul 8 2017

A weak surface low centered between Ainsworth and Broken Bow
this afternoon will weaken this evening. Isolated to widely
scattered thunderstorms will be possible this evening in the
vicinity of the low, where weak surface convergence is noted along a
couple of surface boundaries. Otherwise a mostly clear sky is
expected with lows in the upper 50s and 60s.

Hot weather is expected Sunday to the west of surface trough which
will be located just east of the area. Mid to upper 90s are likely
at most locations, along with drier air as dew points fall into the
mid 40s to mid 50s as southwest winds advect drier air northeast
across the area. Have removed all pops for Sunday as really no focus
with surface trough to our east.

.LONG TERM...(Sunday night through Saturday)
Issued at 236 PM CDT Sat Jul 8 2017

Upper level high pressure centered across the southern Rockies, will
slowly drift north and be centered across the central Rockies by
weeks end. This keeps flow aloft mostly northwest through the
period. Gradually rising heights aloft through the week will keep
thunderstorm chances low, but not zero. Subtle waves within
northwest flow will have to be evaluated on a daily basis to see
where and when a few thunderstorms could develop. Otherwise very hot
week in store, with GFS ensemble indicating highs potentially around
100 give or take a few degrees through the entire upcoming week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 109 PM CDT Sat Jul 8 2017

Expect scattered high cloudiness of 20000 to 25000 FT AGL over the
next 24 hours across western and north central Nebraska. Isolated
thunderstorms are possible across central and southwestern
Nebraska later this afternoon into the evening hours. Due the
expected isolated coverage of the storms, will forgo mention of
them in the 18z TAF issuance.

.LBF WATCHES/WARNINGS/ADVISORIES...
None.
