More scattered storms on Tuesday

Weather

We saw a round of heavier rain in the morning followed by a lull in the rain through much of the day, a few scattered showers developed this afternoon, but a batch of heavier rain that has been stuck in North Mississippi through much of the day is finally moving east into Alabama. You can track all these showers and storms using our interactive radar on Live Alert 19 or using the map below.

This off and on rainy pattern continues through this week. It’s a frustrating one for us meteorologists, because it’s incredibly hard to pinpoint exactly when to expect rain, and how much you can expect. Today, some additional storms are likely later in the afternoon and evening, with a few potentially intense west of I-65. We don’t expect a lot of classically “severe” weather, but storms don’t have to be severe to disrupt your day. Heavy rain, lightning, and some gusty winds will be possible in the strongest storms.

More of the same through Friday

Day-to-day changes this time of year have more to do with the scattered storms than with a changing weather pattern.

We literally have a chance of a thunderstorm (or two) every single day this week. The spotty, hit-or-miss, uneven nature of the daily downpours mean some daily temperature fluctuation, but over-all, it’s just hot and sticky with thick, tropical humidity in place.

A weak upper-air disturbance (which is just a pocket of cooler air aloft enhancing the jet stream) keeps the atmosphere ‘stirred up’ for the next few days. It’s not enough for widespread, everybody-gets-it soaking rain, but it is enough to generate several waves of heavy thunderstorms. Add all of those waves together and average rainfall by next Monday night likely ends up in the 2-3″ range for most of North Alabama; however, some will get more (maybe 4″+) and some get less (below one inch).
