Short term...(today through saturday) 
issued at 250 am CDT Thursday Oct 2 2014 

Several timing issues will be the main concern in the short term. 
Initial focus will be band of showers and storms starting to 
spread into the area at 07z from central Nebraska. Models 
continue to suggest a steady progress of this system across the 
County Warning Area today in advance of the upper trough. Latest rap has the 
majority of the precipitation east of the area by 00z. Also may need a 
mention of fog for a short time this morning in west central Iowa 
between Harlan and Red Oak where visibility is reported near zero. Will 
monitor until issuance for any change as cloud cover begins to 
spread into that area. 

A new feature that has shown up in tonights models is a secondary 
band of showers behind the primary cold front associated with 
another short wave as it moves into Nebraska tonight. At this 
point have kept probability of precipitation on the low side and mainly for western and 
southern parts of the area as indicated by 00z models. 

Otherwise weather turns windy and cold behind the front tonight 
into Friday with good potential for frost or freeze across most 
of the area Saturday morning. At this time will continue mention 
of this potential in the severe weather potential statement and wait until later forecast for 

Long term...(saturday night through wednesday) 
issued at 250 am CDT Thursday Oct 2 2014 

Generally dry and warmer in the extended period until towards the 
end of the time frame when another frontal system with upper level 
support develops over the region. Probability of precipitation on the low side for now due 
to uncertainty in postion and timing.
