.DISCUSSION...
Issued at 307 AM CDT Tue Sep 12 2023

Key Messages:

 - Below average temperatures and dry conditions are expected
   through Thursday

 - A weak cold front will bring chances for rain to the region
   from Thursday evening through early Saturday morning.

Upper level ridging over the northern Plains will keep
precipitation chances out of the region through Thursday
afternoon. Temperatures will continue to be below average with
highs in the 70s and lows in the upper 40s and low 50s. Humidity
will also remain low across the region with dew points in the 
40s.

Thursday evening, a weak cold front will approach the region from
the northwest. This will bring chances for rain showers across 
northeast Nebraska for Thursday night (20-30%), and for the 
entire region Friday afternoon/night (20-40%). Recent model 
trends have begun to depict faster frontal motion compared to 
previous runs, so rain chances in southwest Iowa and southeast 
Nebraska for Saturday morning appear to be diminishing at this 
time (<20%). 

Saturday through the end of the forecast period, seasonable
temperatures (highs around 80) and dry conditions will prevail
across the region as another high pressure system builds into the
northern Plains.
