In the upper levels, a ridge remains centered over the Southeast. At the surface, a stalling boundary is stretched over Kentucky and west Tennessee. Currently, showers and storms are present upstream along the aforementioned boundary. CAMs have this line dissipating before or as it moves into our region but a few stray showers are possible mainly near the Upper Cumberland Plateau and Southwest Virginia. Today, the front will lift north but a few showers will be possible mainly in Southwest Virginia. Today will be hot again with highs in the 80s. All three climate sites are forecast to break or tie the record high today. CHA and TRI broke their record highs yesterday (Wed).

Thursday night, a deep trough will move into the Midwest and into the Ohio Valley by afternoon. The surface low will move through the Great Lakes and into New England bringing a cold front through the Tennessee Valley in the late afternoon or early evening hours on Friday. Winds will be gusty Friday afternoon and evening with gusts up to 30 mph likely at times. The best chance for showers will be Southwest Virginia, Northeast Tennessee and along the East Tennessee mountains and foothills in the late afternoon and evening hours. Thunder chances will be low with low instability expected.

The weekend will be dry and much cooler with highs in the upper 50s and lower 60s Saturday. Only slightly warmer on Sunday with highs in the mid 60s. Temperatures will be cold enough for frost on Saturday and Sunday nights mainly in Southwest Virginia, Northeast Tennessee and the higher elevations.

Early next week will be dry with highs warming into the 70s by Tuesday as ridging and high pressure dominate the Southeast.
