Heavy rain moving through North Alabama, then cool and dry for Memorial Day Weekend!

Weather

The Storm Prediction Center outlines a marginal risk of some severe storms for North Alabama and Southern Tennessee on Friday, which means that a strong wind gust or two is possible as a line of thunderstorms moves through the Tennessee Valley.

Heavy rain is expected to move through north-central and northeast Alabama through 7pm Friday evening before exiting North Alabama into North Georgia.

Little to no instability is available for these showers, which means that while gusty winds are possible, they will likely remain below severe limits (less than 58 mph). In addition, a few lightning strikes are possible, but frequent lightning is no longer a threat for the region Friday afternoon into Friday evening.

The heavy rain showers will clear out of North Alabama Friday night, though a blanket of cloud cover is expected to linger overnight into Saturday morning. Mostly cloudy skies are expected again Saturday afternoon, making for a rather chilly start to the holiday weekend.

Memorial Day Weekend and beyond

Three of the past four days felt like July with temperatures climbing into the low 90s. It’s been humid, too, as dewpoints climbed into the upper 60s to low 70s this week — that’s the stifling, miserable territory!

Thankfully, a break from the thick humidity is in the forecast this weekend, and when dry air moves in, it often helps turn the temperature down as well.

Friday’s thunderstorms are courtesy of a cold front that will bring dewpoints as low as the 40s this weekend, which means morning low temperatures will dip into the upper 40s to low 50s — in late May!

Afternoon temperatures will only reach the low to mid 70s for Saturday, and they will stay in the 70s on Sunday. This is roughly 10 degrees below average for late May — just in time for neighborhood pools and city aquatic centers to open for the season!
