Weather Summary for Iowa
National Weather Service Des Moines IA
436 AM CST Tue Nov 21 2017

After Monday brought some very mild air to the region, Tuesday will
be a much, much different day in terms of weather. Temperatures Monday
afternoon topped out in the mid 50s to low 60s across much of Iowa.
These temperatures remained warm overnight as 4 am temperatures along
and south of Interstate 80 were in the upper 30s to low 40s. Normal
lows for this time of year are in the mid 20s, placing the actual low
temperatures for this time of year a solid 10 to 15 degrees above
normal. Across northern Iowa, however, a cold front had begun to make
its way southeastward into the state. Behind this front, temperatures
were already in the mid to upper 20s. Winds were also starting to
pick up behind the front, as speeds were reaching 10 to 20 mph, with
gusts to 25 mph.

For today, the strong winds and cold temperatures will win out as the
above-mentioned cold front continues to rapidly push through Iowa. In
fact, temperatures for the rest of today will struggle to even rise
more than a few degrees, as they may even drop a degree or two
throughout the day. Winds will be very strong, blowing from the
northwest at around 20 to 30 mph, with gusts of 35 to 45 mph. The
strongest of these winds should be during the morning hours and
located all over northern into northeastern Iowa.

The rest of the week will bring some roller-coaster temperatures, as
we should stay cool again Wednesday, but warm up Thursday, and
especially Friday. Highs Thursday will be near 50 degrees, and highs
on Friday will likely punch into the 60s, with upper 60s not even out
of the question in central to southwestern Iowa. The record high for
Friday at Des Moines is 67 (2011). This value may be broken. For the
weekend, highs look to be back into the 40s and 30s. There are no
significant widespread precipitation chances at this time.
