SUNDAY NIGHT: An isolated shower can’t be ruled out through around 7 pm, then it’s the typical warm and muggy evening we all expect this time of year. Lows in the low to mid 70s with a partly cloudy sky.
MONDAY/TUESDAY: A strong upper-air ridge will be in place across the Southern Plains and Four Corners states Monday into Tuesday, with a weak upper-air trough in place across Alabama. That trough will lead to some additional rising motion in the atmosphere here and help kick-start more numerous showers and storms Monday and Tuesday than we’d normally see on a July afternoon. The best chance for heavier rain will be on Monday, and north of I-20, but we do expect widely scattered storms to continue to push southward through the day Monday. Tuesday, the upper-air trough begins to strengthen, but also begins to push east. Still, expect at least scattered storms to remain through Tuesday afternoon.
WEDNESDAY: Rain chances dwindle on Wednesday as the upper-air trough moves eastward. This will be a day in-between systems, but expect the heat to build with fewer clouds around. Highs reach the mid 90s with the heat index back into the triple digits.
THURSDAY: A second weak upper-air trough digs across the Central U.S. Thursday, and we’ll get enough rising motion from that to again increase our coverage of showers and storms. For those without rain and cloud cover it will be another hot day with the heat index again in the triple digits.
FRIDAY & THE WEEKEND: That upper-air ridge slides east Friday into the weekend and strengthens across the Central and Southern U.S. This is a pattern that supports extreme heat over the state of Alabama, and we’d typically expect to see heat advisories become necessary in a pattern like this. Right now, we’re forecasting highs to climb into the upper 90s by next weekend, and the heat index to climb above 105°.
