Area Forecast Discussion
National Weather Service North Platte NE
301 PM CDT TUE JUL 5 2016

.SYNOPSIS...
Issued at 301 PM CDT Tue Jul 5 2016

Isolated to scattered showers with a few embedded thunderstorms have
been ongoing most of the day across the area. This has kept temps
cooler than originally expected due to the clouds, however in a few
locations where the sun was able to shine for a few hours temps
soared into the mid 90s (like OGA which last ob reported 96). A
surface low was analyzed across S Dakota with a warm front into Iowa
and a cold front trailing into Wyoming. Little change from yesterday
with the upper levels as generally zonal flow across the high
plains.

&&

.SHORT TERM...(This evening through Wednesday)
Issued at 301 PM CDT Tue Jul 5 2016

A couple of weak boundaries across the CWA late this afternoon will
be focus for some isolated/scattered thunderstorms. CAPE is good
however marginal shear. Storms will move quickly to the northeast.
More of a focus will be the an upper level disturbance as it drifts
across the area. The wave has already started to fire convection
across se Wyoming and ne Colorado. Meanwhile overnight the cold
front will drift across the area and stall to the south.

Models are expecting more sun in the wake of this evenings storms
with highs in the upper 80s to mid 90s, warmest across sw zones. At
this time this looks good however was expected more sun today which
gives me less than normal confidence. Still going to see moisture
across the area and another reinforcing cold front will approach the
area. In addition should see another upper level disturbance.
Tomorrow the shear is a little stronger and continue to see good
afternoon instability. Good model consensus about storms firing
early across western S Dakota and pushing to the southeast with the
cold front. The question is the southwestward extent of the
development and the timing. High pops across n central and will
monitor for western Nebraska.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 301 PM CDT Tue Jul 5 2016

Jet lies along the US canadian border with mainly zonal flow
across the lower 48. Stationary boundary will lie across western
Nebraska on Wednesday with convection continuing into the evening
mainly over northern Nebraska as upper trough moves onto the
northern plains. Showers ending over north central zones Oneill
vicinity as we get on backside of upper trough. Highs Thursday and
Friday in the 80s as cooler air filters in behind the upper low.
Heat returns Saturday and Sunday as ridge builds in from the west.
Precipitation confined further west as it develops along the front
range of the Rockies and then moves east into more stable air and
diminishing. Stronger upper system moving into Idaho through the
weekend with increasing chances of precipitation through western
Nebraska through the beginning of the work week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1245 PM CDT Tue Jul 5 2016

Active weather across the area the next 15 hours. Isolated to
scattered showers with a few embedded thunderstorms early this
afternoon with additional and stronger storm development expected
later this afternoon into the evening hours. Coverage still
questionable and whether a direct impact to the terminal will be
seen. Higher confidence of impact over southwest into north
central Nebraska which impacts the KLBF terminal and looks to be
south and east of the KVTN terminal. Some of the storms could be
strong with gusty winds this evening. Overnight the thunderstorm
chances diminishes with generally light winds and high clouds
which continues into Wednesday morning.
