.SHORT TERM...(This evening through Thursday)
Issued at 333 PM CDT Wed Jun 21 2017

Models in fair agreement this afternoon. Laps has surface trough
lying from Bassett to North Platte with winds out of the south
and gusty to the east of this line and out of the north to
northwest with much drier air to the west of the line.
Temperatures in the 100s over southwest Nebraska. Even with
southerly flow to the east dew points in the low 60s and this is
keeping temperatures from torching out as in the drier air, with
dew points in the 30s and 40s to the west southwest. Have numerous
boundaries across western Nebraska today from convection south
and north last night. Fairly high convective clouds developing
this afternoon with temperatures hovering around the century mark.
Little vertical extent. Cloud field from Curtis to Hyannis and
southwest. Notable boundary from Ainsworth to Broken Bow to North
Platte. Waiting for initiation. Lows tonight in the 50s and 60s.

Highs on Thursday with the cold front moving south will be in the
70s and 80s north to the low 90s southwest. Increasing chances of
thunderstorms to the east in the morning and shifting south
through the day with the cold front. Main area of concern will be
the southwest along the front on Thursday afternoon and evening.

.LONG TERM...(Thursday night through Wednesday)
Issued at 333 PM CDT Wed Jun 21 2017

Showers ending over southwest Nebraska Friday morning with lows in
the 40s and 50s. Highs Friday only in the 70s with surface high
pressure building into western Nebraska and gusty north winds.
Showers redevelop along secondary cold front moving through after
midnight as the upper closed low moves through Minnesota. Much
cooler on Saturday with highs around 70. Models in flux with
sensible weather Saturday night and have gone with consensus with
showers over southwest nebraska through the evening. Still not
sold on this feature. Retained a few showers southwest through
Sunday with highs only in the 70s. Temperatures rebounding into
the first part of the week with temperatures climbing back into
the 80s and some chances of precipitation returning in northwest
flow.
