Hot With Near Record High Temperatures Today

Breezy southwest winds will develop today over southern Wisconsin.  The breezy southwest winds are due to a tightening pressure gradient between an approaching cold front and stationary high pressure over the Ohio Valley.  These winds will tap into a bubble of dry, hot air over the Plains and pull it into southern and central Wisconsin. 

As illustrated by the below graphic, the area in red experienced high temperatures of 95 or warmer on Wednesday.  Numerous locations reached the triple digits including Sioux Falls SD (100F), Bismarck ND (102F) and Sioux City IA (101). 

Hot Temperatures today

Under sunny and breezy conditions, high temperatures are expected to climb into the middle to upper 90s this afternoon over southern Wisconsin.  Fortunately, the humidity will remain low which will lessen the deadly affects of the heat. Never the less, people working outside this afternoon should take frequent breaks from the heat and keep plenty of water close at hand.

Milwaukee's record high temperature today is 96, set in 1958.  Madison's record is 97, set in 1953.  Both of these records will be approached or exceeded today. 

The hot temperatures will still cause the inside of vehicles to rapidly heat to dangerous levels.  Make sure all children have left the vehicle when you reach your destination. Check out our weather preparedness page for hot weather safety rules.
