The weather across the Tennessee Valley is quiet on this Wednesday. We have mostly sunny to partly sunny skies in place behind the cold front that brought the strong storms to our area yesterday and Monday. That has moved into central Alabama and stalled, and it will be coming back northward overnight and into tomorrow as a warm front ahead of the next storm system. Until then, temperatures today are in the low to mid 70s over southern middle Tennessee and upper 70s to lower 80s over north Alabama and north Mississippi. Thunderstorm activity has been restricted to central Alabama on the south side of that frontal boundary.
Futurecast is a few degrees too warm with the temperatures, especially over southern middle Tennessee, but it has the right idea that we remain mostly cloudy this afternoon with rain-free conditions across the area. Temperatures drop back into the 60s after sunset, and then may briefly reach the upper 50s after midnight before warming again toward daybreak as the warm front moves north, so that we are in the mid 60s to as warm as 70 as we begin the daybreak hours of Thursday morning. A stray shower will be possible during the morning hours as that warm front lifts northward, but the vast majority of us will be dry.
As we head into the afternoon, a few popup isolated storms may form across the area during the heat of the day, but the main thunderstorm action will come between 7PM and Midnight Thursday night across our area as a cluster of thunderstorms moves in from the west. These storms will be weakening as they move across, but one or two could still produce gusty winds of 40 to 60 mph. We can't rule out a stray severe thunderstorm warning or two. Scattered showers linger into Friday morning before the main cold front moves in during the late morning into the afternoon and sparks off more scattered showers and thunderstorms. One or two of these may also be strong with gusty winds and small hail. That activity ends by the evening as the front moves through the area.
Clouds will linger into Saturday under the upper-level low, and we might even have a shower or two. Temperatures will be in the mid 70s for Friday and Saturday. However, we quickly start a warming trend by Sunday that carries us into next week. We'll be in the mid 80s for Sunday and Monday, and by the mid to latter part of next week, we may very well be close to 90 degrees for the first time this year as a ridge of high pressure builds in across the area.
