Surface Data - Midwest Current  


1Daily Barometer Graph

Another perfect warm day in early March! Temperatures climbed into the mid 60s today as warm weather continued to be blown northwards as the winds were from the south again today. The barometric pressure trend has risen considerably over the course of 24 hours as is noted by the high pressure system sitting between WI and MI. There is a weird shift of winds around southern WI and IL which is most likely from a warm air mass and cold air mass colliding in that area. Different pressure systems lead to different wind patterns as winds blow in a clockwise position around a high pressure system and counterclockwise around a low pressure system. The skies were mostly clear today with high level cirrus clouds through most of the sky which is generally a sign of fair weather.
