HIGH PRESSURE STRETCHING FROM THE DAKOTAS INTO THE NEBRASKA  
SANDHILLS THIS AFTERNOON WILL BUILD THROUGH THE MID MISSOURI VALLEY

INTO THE UPPER 50S TO MID 60S. PATCHY FOG IS POSSIBLE TOWARD  
DAYBREAK ON MONDAY, ESPECIALLY ALONG THE MISSOURI RIVER.  
 
A TROUGH OF LOW PRESSURE WILL DEEPEN OVER THE HIGH PLAINS ON MONDAY,  
RESULTING IN STRENGTHENING SOUTH WINDS. HIGH TEMPERATURES WILL RANGE  
FROM THE LOWER 90S ACROSS PORTIONS OF EASTERN NEBRASKA TO LOWER TO  
MID 80S OVER SOUTHWEST IOWA.
