Patchy fog had developed across parts of Iowa this morning with light
and variable winds and low temperatures in the lower 30s south to
lower 40s south. The area with the thickest fog was over southeast
Iowa with visibilities one mile or less. By late morning, temperatures
had warmed into the middle and upper 40s east to the lower and middle
50s elsewhere.

High pressure will continue to advance eastward into the Ohio River
Valley today while low pressure over the plains will deepen across
Nebraska. Showers are forecast across the Dakotas and Nebraska today
with the activity spreading into western Iowa by late afternoon. The
low will push slowly east tonight into southern Minnesota with a cold
front sweeping east through the Missouri River Valley. Showers and a
few storms are expected ahead of the front across Iowa and Missouri
tonight. Meanwhile, steady rain will continue across the Dakotas as
strong northwest winds develop in the Plains overnight. The strong
winds are forecast to spread east into Iowa Monday afternoon and are
expected to persist into Tuesday as the low slowly pulls northeast out
of the region. Temperatures on Monday and Tuesday will also be cooler
with highs holding in the 40s and 50s for much of the Midwest.
