Weather Summary for Iowa
National Weather Service Des Moines IA
412 AM CST Tue Feb 21 2017
A weak boundary continues to exit southeast Iowa early today. Clouds
accompany the boundary over the east early today with light northwest
winds and temperatures in the lower 40s to lower 50s. Over portions
of central and western Iowa where skies have cleared temperatures have
fallen into the lower to mid 30s and patchy to areas of fog have
developed. Winds are light over the west and central early today.
Some dense fog will be possible during the morning commute...but by
later this morning the fog will lift as temperatures warm and winds
begin to increase. Southwesterly winds of 10 to 20 mph will bring a
return of much warmer air once again...setting the stage for additional
record highs this afternoon and again on Wednesday when temperatures
once again reach the 60s to 70s both days.
The spring-like weather is expected to come to an abrupt end Friday.
A significant pattern change will occur as a winter storm moves through
the Central Plains. A return of colder weather along with snow or a
mixture of rain changing over to snow will occur on Friday. The better
chances for any significant snow remain over the northern and northwest
areas of the state...along with surrounding locations in portions of
Nebraska...Minnesota...and Wisconsin. Winds on the backside of the
storm will cause blowing and drifting of newly fallen snow as well.
With some uncertainty still in the forecast with regard to the track
of the storm...anyone traveling Friday and this weekend should pay
close attention to the forecast for the region over the next several
days. More information about travel conditions and snowfall amounts
will be available with later forecasts. The weather pattern will
remain active into next week with more precipitation in the offing.
