The weather pattern across the country will see an upper ridge in the west and a trough in the east. This patter will favor a dry trend from much of the Plains westward and scattered showers in the east.
Scattered showers are expected with the trough through the weekend at times in the Northeast and eastern Great Lakes with much of the Midwest seeing some of this activity Saturday and the Ohio River Valley on Sunday. The majority of this rain is expected to be light, and cold enough air could build far enough south from Canada for wet snow to mix in at times or change over to wet snow for a short period in parts of Northern MN, northern WI, and the UP of MI.
Further south and east a front will be stalled out over central or southern FL and extend northeast into the Atlantic. Showers and storms are expected to increase in coverage potentially gradually throughout FLthe next few days with heavy rain at times. This activity could reach the southeast GA and Carolinas coasts by Saturday overnight, then head up the Mid-Atlantic coast Sunday and making it to southern New England by overnight Sunday.
Finally, a tropical system is developing in the southern Gulf of Mexico and expected to become a named storm within the next 48 hours. This system will have to be monitored into next week as it potentially could threaten the US Gulf Coast.
