A huge low pressure system and cold front has greatly dropped the temperatures in the Mid West.  The low pressure system sitting North East of Lake Superior is bringing strong winds from the West and with this low pressure system is a cold front.  Yesterday this cold front brought rain in the morning and then a little last night.  The water vapor has cleared a little bit dropping to 57 percent relative humidity.  Because of this cold front and another elongated cold front in Texas to Georgia, expect temperatures to remain very cold for late April.  The south winds are not being allowed to move north.

This low pressure system along with multiple cold fronts is causing rain in the Eastern part of the United States.  Expect this to be a common theme all the way to Thursday
