Rain Chances Increase for Sunday – Saturday Evening Forecast Update 9 PM


We enjoyed some hazy sunshine across the area today as temperatures climbed into the middle 80s. Most of the rain showers were south of west Alabama, but we do have a few showers and storms on the radar over south-central Mississippi and these will continue to move slowly northward overnight. However, I’m not expecting anything widespread across the area tonight.

As we head into Sunday, broad southwesterly flow aloft will prevail and embedded “pieces” of energy will moving across the area, so we can expect a pretty decent coverage of showers and storms across the state tomorrow. Some of the higher resolution model guidance is suggesting a more concentrated area of showers and storms over the southeastern half of Alabama, leaving west Alabama mainly dry. However, with the broad uplift expected combined with lots of moisture, a shower or storm is possible anywhere across the area at any time during the day Sunday even into Sunday evening.

We’ll have a frontal boundary approach during the morning hours of Monday in association with a departing trough of low pressure. A few showers or storms are possible with this feature early Monday, but by Monday afternoon, the sky should begin to clear as the rain shifts south and east of our area. Highs will remain in the mid to upper 80s.

The GFS/Euro models agree on a fairly strong ridge of high pressure aloft moving in from the west for the middle of the week. This will mean warmer afternoons with highs getting into the low 90s, and smaller rain chances. Dew point temperatures remain quite high throughout the week, so we cannot rule out a stray storm for Tuesday through Thursday. By Thursday afternoon, a weak system skirts our area, and we may see a slight uptick in rain coverage Thursday evening into Friday morning. For now, the first part of the weekend looks warm and dry!
