.SHORT TERM...(This evening through Tuesday)
Issued at 317 PM CDT Mon Jun 19 2017

Near term models in good agreement this afternoon. Convective cloud
field from Montana to Nebraska in fast northwest flow. Disturbance
over Regina seen moving into northern North Dakota will move
southeast through the Dakotas and Minnesota this evening. Light and
variable winds tonight with clear skies and fairly dry air at the
lower levels will allow heat to radiate out with lows in the 50s.
Light winds Tuesday as surface trough moves into southwest Nebraska.
Southerly winds developing and ridge building east temperatures back
into the 80s and 90s. Models have dryline north into southern
Nebraska. Thunderstorms possible along the dry line late afternoon
into early evening. Have retained slight chance pops.


.LONG TERM...(Tuesday night through Monday)
Issued at 317 PM CDT Mon Jun 19 2017

Tuesday night with southerly flow lows bottom out in the mid 60s.
Fairly muggy as dew points build to around 60 with the moisture
advection on southerly flow. Wednesday as the ridge and heat push
east temperatures in the 90s spread north into the Sandhills ahead
of a cold front moving across western Nebraska through late
afternoon. Timing of front will be key to high temperatures and
convection. Outlooked for marginal east of a line from Ainsworth to
Hayes center now. Thursday evening precipitation still dependent on
timing of front and front may slow down some with the setting of the
sun. Have retained pops and weather. GFS has post frontal
precipitation over the northern Sandhills after midnight as an upper
wave moves into the Dakotas and a stalled out front over southern
Nebraska lights up Friday. Back into the 40s and 50s for lows over
the forecast area on Saturday morning. Highs Saturday in the 60s and
70s with strong north winds and good cold air advection. Lows Sunday
morning in the 40s over all of western Nebraska. Highs Sunday in the
70s
