Fewer Storms, but Building Heat Heading Into the New Week

Scroll for more content...

The potential for an isolated severe storm or two is present again as we start this Sunday morning. Storms are expected to develop along a boundary that has stayed in position over northeast Mississippi (just south of and adjacent to the Tennessee border). This boundary will be the favored location for storms to develop and gain at least some measure of organization.

The main concerns associated with storms will be: the potential for some isolated instances of a large hail (greater than 1" in diameter), heavy rainfall, lightning, and isolated damaging gust of wind or two in the 40, 50 or perhaps as much as 60 mph range and a very very very low but threat of a tornado. It seems likely that until the sun comes up storms will struggle to maintain their intensity and organization as they move primarily along and just south of the Tennessee border moving eastward towards northwest Alabama. Really until sunrise, the atmosphere which has stabilized overnight will not be as conducive to severe storms as it could potentially be later in the morning or by early afternoon.

Meanwhile, temperatures will begin in the middle and lower-70s across the area this morning.

Heading into the upcoming workweek, some isolated showers and thunderstorms will linger. Most thunderstorm activity will, however, will be due to the heating of the day as opposed to stalled fronts or more intense forcing. Temperatures look likely to return to the lower and middle-90s next week with heat-index values in the upper-90s and eventually well into the lower-100s. Overnight lows will generally be limited to middle and lower 70s and will probably be accompanied on a few mornings by isolated patches of fog.
