Sunday Evening Update (6:40pm)- Clusters of heavy downpours with embedded thunderstorms have made their way into the Tennessee Valley this evening. Occasional lightning will be likely along with the possibility of occasional wind gusts above 50mph and small hail. Thus far, no severe warnings have been issued and the general threat for damaging weather remains limited from these storms; however, isolated wind gusts above severe-limits (58mph or greater) are not out of the question.
Most of this round of storms exits the Tennessee Valley around 8pm or so, but some additional showers or storms are a possibility deeper in the evening. Rain chances become slimmer after midnight, although isolated showers cannot be ruled out through the wee hours of the morning.
Warm, humid, and breezy Memorial Day: Rain isn’t guaranteed in every Tennessee Valley community on Memorial Day, but it’s likely we’ll see a scattering of showers and thunderstorms develop during through the day–some producing heavy downpours. Severe weather doesn’t look like a big issue, but lightning could be a hazard to folks spending time outside, and we can’t rule out some stronger winds or hail from a few storms. It’s a good idea to have alternative indoor plan in mind, or at least keep within close access to a building that can shield you from a passing storm.
Unsettled week ahead: The chances vary a little from day to day, but there is at least the prospect of a shower or storm at just about any point during the daylight hours each day through next weekend. This doesn’t mean each day is going to be a washout or even that your particular neighborhood is assured rain every day; there will be extended lengths of dry weather as well. When showers aren’t affecting your location, the weather will be seasonably warm and humid.
