FIRST ALERT WEATHER: Mostly sunny skies with heat index approaching 100°

(WAFF) - It's a warm and muggy start to the day, and temperatures will heat up quickly for this Fourth of July. Look for mostly sunny skies into the afternoon with temperatures pushing into the 90s by midday. Highs should top out in the mid-90s this afternoon with a heat index approaching 100°.

It could be breezy at times with winds gusting to 20-25 mph out of the southwest. Hit-or-miss pop-up storms is possible this afternoon with chances getting higher this evening. We'll have to watch as an outflow from earlier storms to our west may trigger more widespread storm activity here in the Valley this evening/tonight.

Should that happen, delays would be possible for some fireworks displays. Some of these storms will be strong with frequent lightning, heavy rains, and gusty winds. Skies will stay partly/mostly cloudy tonight with lows in the low-to-mid 70s.

A weather disturbance passes to our north Tuesday morning, and that should lead to more widespread rain across the Valley mainly from the morning into the early afternoon. Highs won't be as hot as today, but should still make it to near 90°. We'll be heating back up as we head towards the close of this week.

At the same time, our rain chances will be slim and drought conditions could worsen across northern AL and south TN. Highs should be into the upper 90s by Thursday and will remain hot into the weekend. The heat index on these afternoons should top the low triple digits.
