around 29.7 inches and associated cold front this morning. winds 
will approach gale force later this morning through this

pressure moves from the northern plains into the ohio river

there is a potential for some southerly gales during this time. 
this low will cross northern minnesota and move over lake superior
dragging a cold front across lake michigan. behind the front 
friday morning, brisk northwest winds are expected. these brisk 
north to northwest winds will persist through monday.
