Tropical Update
Showers and thunderstorms in association with an area of low pressure located about 300 miles south-southwest of the Azores have not become any better organized. This system still has the potential to become a subtropical cyclone before upper level winds become unfavorable. Regardless of development, this low is expected to produce winds in excess of 40 mph over the next day or two while it slowly moves northeastward.

A Look Ahead
An area of low pressure in the Central Plains will move northeastward toward the Great Lakes on Friday. The associated warm front will begin lifting northward and allow southerly flow to bring moisture northward. This moisture will allow instability to build across the Missouri River Valley. With the associated cold front tracking eastward, showers and a few severe thunderstorms will likely develop along and ahead of the cold front during the afternoon and evening. Small hail and damaging winds will be the primary hazards. 

Further north across the far Upper Midwest, light to moderate snow may develop as cold air is drawn in behind an area of low pressure. At this time, anywhere from a trace to a few inches of snow will be possible.
