Warm and humid with spotty storms for the rest of the week
A round of heavy showers and storms moved through much of the Tennessee Valley Tuesday afternoon. Only spotty sprinkles and areas of drizzle are in the forecast this morning along with some locally dense fog.
We’re still stuck in the unsettled southwesterly flow of the past few days, which will help keep it feeling damp and muggy through the overnight hours and into Wednesday morning. It will also keep the chance of a few widely scattered storms in the forecast Wednesday and Thursday. Expect the same situation of the past few afternoons: Storms will be hit and miss, but could still bring locally heavy downpours.
A changing weather pattern: The best way to describe the current weather pattern is simply ‘disruptive’. We don’t see any major systems coming our way, but we still get those daily rain chances through the week.
Instead we’re focusing on timing out upper-level disturbances. These are essentially pockets of energy that swing in from the west and pair with our warm/humid air. The two together spark the ‘waves’ of rain we’ve been dealing with the past two days. They can be tricky to time, but the next *best* chance of rain will likely come at us early in the day Friday. Until then it’s the same afternoon pop-up storm chance each day.
Hurricane Gert: Tropical Storm Gert became a hurricane late Monday night. The storm could still strengthen over the next 24-48 hours, but it won’t be impacting land. Gert stays out in the Atlantic, tracking into the northern Atlantic sea by this weekend.
Eclipse weather coming into focus: Next Monday’s Great American Eclipse looks to be happening at a good time for us! Some drier air will be filtering in from the north, giving us a break from the consistent rain chances.
Unfortunately we can’t totally rule out the chance of a pop up shower at this point, but it looks more likely that we’ll be dealing with puffy afternoon clouds.
We still expect good viewing conditions in Alabama and Tennessee next Monday afternoon; however, parts of Kentucky, Missouri and points northwest may have a tougher time with clouds and storms.
