DISCUSSION

Issued at 142 AM EDT Sat Apr 4 2026

Currently, ridging and high pressure are still over the region. A few showers or storms may move through the North Carolina counties this morning. Some isolated shower or storm activity is possible areawide by late morning and early afternoon as the ridge starts to break down. By mid afternoon, coverage will be isolated to scattered with summerlike pulse showers and storms expected with very warm temperatures with highs in the lower 80s again today in the TN Valley.

By this evening, widespread showers and storms are expected as a cold front approaches. This system will have good upper level support with a trough making it into the Southeast. At the surface, the parent low will move through the Great Lakes bringing a cold front through the region early Sunday morning. A few strong storms cannot be ruled out but instability looks very low with storm timing late in the evening. Dew points will only get into the lower 60s in the Tennessee Valley. Much of the region will get a much needed rain with forecast rain totals around one inch.

Southwesterly winds will be gusty today ahead of this system with gusts around 25 mph expected in the TN Valley at times. Gusts will be a bit higher in the East Tennessee mountains and foothills but will likely stay below Wind Advisory criteria (gusts 40 mph+) with 850 mb winds peaking around 30-35 knots with more of a southwesterly wind direction that is not as favorable for downslope enhancement. Though I would not be surprised if some of the tallest peaks hit 40- 45mph but it will likely not be widespread enough for an advisory.

Rain will start to taper off Sunday morning as a much cooler air mass moves into the region. Highs from Sunday through Tuesday will be closer to seasonal normals in the 60s. Much cooler than recent weather. Frost may be a concern Monday through Wednesday mornings especially for the northern half of the region and the mountains. Dry weather will continue through the workweek and a warming trend will start Wednesday with highs getting into the 70s through Friday for most of the TN Valley.

AVIATION

A few scattered rain showers or thunderstorms likely this afternoon, mainly in northeastern TN. A PROB30 at KTRI is to account for that activity.
