A strong ridge of high pressure stretching across much of the U.S. and into Canada is keeping conditions calm for most of the country, including our region. While a surface trough may spark a few very isolated sprinkles, the majority of us will stay dry and enjoy a mix of sun and clouds.

The clouds that we saw today will stick around through the overnight and low temps will generally drop to the high 60s. That surface trough I mentioned tries to squeeze out a few showers overnight, but not much at all is expected.

Tomorrow’s Forecast

Highs tomorrow will reach the upper 80s under a mix of sun and clouds, with humidity staying fairly manageable. By mid to late afternoon, around 3-4 PM, a few showers could develop, so some spots could see some quick rain, while others stay dry. Overnight, skies will gradually clear and lows will drop into the middle/upper 60s.

Thursday’s and Friday’s Forecast

Thursday and Friday will be dry with lots of sunshine. Highs reach the upper 80s Thursday and mid-80s Friday, but with dew points in the 50s, it will not feel humid! With moisture that low, it’s tough for rain to develop, so we won’t see any.

Extended Local Outlook

15 Day Forecast for Southern MS/AL/LA

Saturday continues to have nice weather similar to Friday’s with the lower humidity and dry conditions. We are watching an area of low pressure that could form off of a stationary boundary over the northern Gulf on Sunday, which could potentially bring us some increased rain chances for Sunday and Monday. We are still pretty far out, so we will keep you updated with the most accurate forecast throughout the week.

The 6-10 day outlook keeps our region warmer than normal, which I know isn’t the best news if you’re tired of the heat. The good news is that the precipitation outlook is finally showing some darker shades of green, signaling a better chance for above-normal rainfall. This is likely tied to the stationary front expected to linger over the northern Gulf, which could bring rain not only Sunday and Monday but also into early next week. Rain chances in the 15-day forecast are running higher than usual

Latest Tropical Update

Imelda has spared the Carolinas, but is now a threat to Bermuda as the island is in the direct path of the forecast cone. Hurricane Warnings are now in effect for the island as Imelda is still expected to be a Hurricane by the time it approaches Bermuda. We thank Humberto for most of the reason why Imelda turned out to sea, which has been downgraded to a Cat 1 Hurricane earlier this morning while moving out into the open Atlantic north of Bermuda. No other areas to watch are currently outlined, but I would expect more storms to ramp up soon as the Atlantic is fairly conducive for development right now.

Eastern/Central Pacific:

In the Eastern Pacifc, we have Tropical Storm Octave that will spin around in the open waters, capping off as a Tropical Storm before diminishing. To it’s east, there is an area to watch with a high probability of development. This system is expected to ride up the coast to the northwest and it’s moisture could eventually cause some flooding concerns in the southwest into Texas after it weakens.
