Afternoon Weather Update


***Short term forecast needs to be monitored this afternoon***

Rain continues to move to the northeast as skies begin to clear across parts of southern Iowa.  The warm front is pretty much right over northern Illinois and will continue to lift to the north through the afternoon.  Dew points are quickly rising into the mid 70s south of the front while a weak area of low pressure sits just to the northwest across northern Iowa. 

The big question is how thunderstorms will begin to develop this afternoon.  With the warm front moving northward any little disturbance that moves along it will stay to the north keeping storm activity through Wisconsin.  However, the one thing that would bring storms into our neck of the woods later this afternoon would be the fact that the dew points are rising into the mid 70s.  That could provide the instability we need to get things going.  And if it does gusty storms would be likely. But...with the warm air coming in it could also act as a lid on the atmosphere and prevent any further storm development.  I know I've said this before, but this is going to be an afternoon where it's either going to happen or it's not.  Keep checking back and we'll continue to update things as we see them throughout the afternoon.
