The forecast will be pretty similar to what we saw across North/Central Alabama on Sunday, as we’ll start off the day with a decent amount of sunshine. Clouds will start building during the second half of the morning and scattered to numerous showers and thunderstorms will begin popping up mainly during the late morning through the early evening hours. These rain chances will be elevated over the Tennessee Valley and mainly north of the I-59 corridor, and with precipitable water values potentially reaching 2.2 inches, some of the heavier storms will produce some ponding and minor flooding issues. Just like Sunday, these storms will be slow-movers as well, which could also lead to those ponding and flooding issues. Highs across North Alabama will be in the mid-80s to the lower 90s, while Central Alabama will see highs in the upper 80s to the mid-90s. Heat index values may reach as high as 104º, so please be careful if having to work or be outside for extended amounts of time.
WEATHER FOR THE REST OF THE WORKWEEK
Ridging over the southeast will keep the area very humid and hot throughout this last week of July. Rain chances will stay elevated for Tuesday and Wednesday across the area as the tropical moisture involved with Invest 90L will move westward into the area. Tuesday looks to be the day with the highest rain chances, while those higher rain chances will mainly be located over the southern half of the area. However, a surface boundary looks to move into the northern parts of the area that could keep those rain chances slightly higher on Wednesday. Highs on both days will be in the upper 80s to the mid-90s.
Thursday and Friday will be more of your typical summer days as ridging builds over the southeast. The good news is that overall rain chances for Thursday look low enough that nearly everyone will stay dry with tons of sunshine. Moisture will start to work back into the area on Friday that will bring back the standard afternoon shower and thunderstorm chances. Highs on both days will be in the lower to mid 90s.
THE CENTRAL ALABAMA WEEKEND
A trough will start working its way into the area late on Friday and will bring an increase to the scattered afternoon to early evening shower and thunderstorm chances on Saturday and Sunday, at this point the odds will be around 40-50%. Highs on both days will be in the upper 80s to the mid 90s.
INVEST 90L (as of 7 pm Sunday evening): Satellite and radar data indicate that showers associated with a low pressure area located about 150 miles east-southeast of Jacksonville, Florida, remain disorganized and limited in coverage. However, environmental conditions are marginally conducive for development, and a tropical depression could still form overnight or on Monday while the low moves slowly west-northwestward or northwestward, reaching the coast of northeastern Florida or Georgia Monday evening or Monday night. This latest update adds the increased rain chances for Tuesday and Wednesday across Central Alabama as 90L moves westward across the northern Gulf of Mexico and the Gulf Coast.
