DISCUSSION
Issued at 226 AM EDT Thu Apr 30 2026
The cold front has moved through the region and is currently over North GA/AL. Showers are starting to develop along the boundary in Northwest GA. The HRRR has a blob of rain moving into Southeast Tennessee and Southwest North Carolina late tonight which suggests the boundary is stalling. The surface low is currently near the Central AL/MS border, the movement of this low overnight may help bring the boundary and moisture closer to the southernmost counties late tonight. Light spotty showers are developing in Middle Tennessee and will move into the rest of the region overnight.
Today will be dry with highs in the mid 60s to lower 70s for the Tennessee Valley, cooler than recent days. Rain chances are also very low on Friday, afternoon highs a bit warmer in the upper 60s and lower 70s.
Friday night into Saturday, a stalled boundary near the Gulf coast will bring rain to the Southeast as a surface low develops off the coast of GA/SC and moves up the coast. The best chance for rain locally will be in Southeast Tennessee and Southwest North Carolina but the bulk of the rain will be farther south. With dew points expected to be in the 40s there will not be any thunder. Saturday still looks like the coolest day with highs in the 60s in the Tennessee Valley which is 10 degrees below normal. Sunday morning may bring some frost to Northeast Tennessee, Southwest Virginia and the higher elevations.
Sunday, Monday and Tuesday look mostly dry with high pressure over the Southeast. A warming trend begins early next week. Rain chances are expected to increase by Wednesday with a possible cold front.
