| Area Forecast Discussion National Weather Service Mobile AL 1242pm CDT Sunday July 12 2026 Issued at 612am CDT Sunday July 12 2026 Forecast remains on track. MM/25 Issued at 1230am CDT Sunday July 12 2026 For the past couple of days we have seen convection develop along the coast late each night into the morning hours due to low-level convergence along a land-breeze, and we expect the same start for today. Scattered showers and storms along the I-10 corridor this morning will expand in coverage to become numerous inland areas this afternoon. High temperatures today will range from 90-94 degrees, and when combined with surface dewpoints ranging from 74 to 78 degrees, maximum apparent temperatures (heat indices) should range from 100-107 degrees. As daytime heating leads to decreasing stability this afternoon, the environment will be supportive of a few strong to marginal severe storms capable of gusty surface winds, small hail, and frequent lightning as MLCAPE values escalate to around 2,000 to 2,500j/kg. As a result, the Storm Prediction Center has a Marginal Risk of severe weather outlooked for our area north of I-10. The highly positively-tilted upper trough over the Ohio Valley this morning will migrate slowly southward over the Tennessee Valley by noon on Monday. Not much has changed with the overall synoptic pattern through theNear Term - Rest Of Today Through Tonight r than the fact that it looks like the upper low that develops within the trough today is now expected to drop further south then previously indicated, reaching as far south as the central portions of Mississippi and Alabama by Tuesday morning. This slower movement has resulted in an increasing chance of rain on Tuesday. This upper-level feature will then retrograde westward toward the southern plains into midweek under a large elongated upper high pressure area situated over much of the northern U.S. A surface low pressure area reflected in the lower levels under the upper low will also migrate southward from the Ohio Valley to the central portions of Mississippi and Alabama by Tuesday morning before moving westward. At this time it looks like a surface boundary will not enter our forecast area, but will will see a shift to westerly/southwesterly winds between the low to our north an a surface ridge over the Gulf. With PWATs (Precipitable Waters) increasing to an average around 2.3" today and Monday, numerous showers and thunderstorms will occur today, followed by to widespread showers and storms on Monday, and numerous to widespread showers and storms on Tuesday. The potential for localized flooding is still a concern as we anticipate a general 1 to 3" of rainfall across the forecast area through the event, with isolated locations receiving up to 4". The Weather Prediction Center has our area outlooked for a Marginal Risk (level 1 of 4) for excessive rainfall over the next 3 days, but did introduce a Slight Risk (level 2 of 4) for our coastal communities for Monday. We will resume our typical mid-July weather through the latter half of the week as upper high pressure rebuilds over the region. /22 Marine Issued at 217am CDT Sunday July 12 2026 Light to moderate southwest flow continues today, becoming a moderate westerly flow Monday. A brief window of moderate to strong westerly flow may exist late Monday afternoon into Monday evening. Forecast trends will be monitored for any potential need for a Small Craft Advisory. Small craft should exercise caution Monday afternoon into Monday evening. Light to occasionally moderate westerly flow prevails through the remainder of the week. Seas remain 2 to 3 feet in height through mid week, potentially reaching 4 feet late Monday. Higher winds and seas can be expected with any thunderstorms through mid week, with best coverage of storms each morning near daybreak over the marine waters. MM/25 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...None. FL...High Rip Current Risk from 7pm CDT this evening through late Tuesday night for FLZ202-204-206. MS...None. GM...None. |
