Forecast updated 7:10 pm EDT - 9 Nov 2011
Following the colder temperatures affecting much of the Midwest by the end of the short term period, a large region of strong WAA develops.This will act to drive weekend high temperatures into the upper 50's. Today's 18Z GFS run (below) shows this warm air advection building in a thermal ridge across the IL/IN/OH/MI region. Otherwise, dry conditions are expected across this region through Saturday with the next chance of rain arriving Sunday.
With the passage of this next system, GFS shows the development of a very strong upper level jet streak over the Midwest. The precipitation associated with this is expected to be primarily along the southwest region of the streak (right-rear entrance region).
