Windy conditions have not backed down this afternoon with much of 
Iowa seeing wind speeds greater than 20 miles per hour. Some areas 
have seen gusts upwards of 50 miles per hour. A wind advisory remains 
in effect for most of the state until 6 PM. Temperatures right now are
ranging from the lower 30s to upper 40s with wind chills anywhere 
from the mid teens to upper 30s. Heavy cloud cover will remain with us
overnight, and temperatures will drop to the upper teens to lower 

Tomorrow will be a little colder with gloomy skies sticking around
with us. High temperatures will be in the mid to upper 20s. The
weather will be quiet, but looking to Thursday night into Friday
morning there is a slight chance for snow for most of the state with
little to no accumulation expected. Temperatures will warm slightly
Friday and into the weekend to the mid 30s to upper 40s. With the
weekend comes a chance for rain and snow overnight Saturday and into
the day Sunday but above freezing temperatures will keep the snow 
from sticking around for too long. Next week will be much of the same
story with temperatures in the upper 30s to lower 40s and fairly 
quiet weather.
