Gulf Tropical Moisture To Move Inland

Tropical moisture will stream inland over the next few days resulting in heavy rain over livestock production areas within Kentucky, Tennessee, Mississippi, and Alabama. Between 1 and 4 inches of rain can be expected 

An unsettled area of thunderstorms over the Southwest Gulf of Mexico will push northeast over the next few days. While a named tropical system is not anticipated at this time, tropical moisture will stream well inland resulting in heavy rainfall. 

An anticipated dip in the jet stream will pull this tropical moisture northward ahead of a cold front. Take a look at how far north deep-seeded atmosphere moisture (bright yellow and red shades) pushes. 

Also note the brown shades, indicating very dry air and marking the initial push eastward of an unusually cold airmass. 

The interaction of the cold front and tropical moisture will result in heavy rain from the North Central Gulf Coast northwards across the Tennesee and Ohio River Valleys. 

The passage of the approaching cold front will mark the start to a period of unusually-cold temperatures for a majority of the next two weeks. 

The coldest air will settle in towards the middle of next week with temperature departures from 10 to 20 degrees below seasonal normals.
