Weather Summary for Iowa
National Weather Service Des Moines IA
520 AM CDT Wed Jul 18 2018

Other than a few mid and high level clouds moving across the state
periodically, the sky was mostly clear across Iowa overnight. At 5 AM
temperatures ranged from the lower to mid 60s north and west with mid
to upper 60s south and east. The wind was southeast at speeds under 
10 mph. 

An upper level trough of low pressure will make its way across the
region today through Thursday bringing showers and thunderstorms back
into the forecast. Stronger storms will be capable of heavy rainfall
and the best chance for that will be across the northwest today and
the northeast on Thursday. Any severe potential will mainly reside
over Nebraska but there is at least a marginal risk for severe storms
across far western Iowa this afternoon and evening. This system will
exit to the east on Friday with far eastern Iowa still having a chance
for rain in the morning.  

High pressure will build into the region for the weekend bringing a
return to dry conditions with comfortable highs and humidity levels.
Highs today will be in the 80s. Highs will vary Thursday with mid 70s
northeast to near 90 southwest. Then Friday through the weekend highs
will be in the mid 70s north to the mid 80s south. Overnight lows
through the period will be in the 60s.   

The next chance for rain will come Monday and Tuesday when a strong
low moves across southern Canada dropping a cold front through the
region followed by a trough of low pressure setting up over the Great
Lakes and setting us up for a bit of cooler weather for the middle of
next week.
