HEAT BUILDS WITH ISOLATED STORMS TODAY
Temperatures are climbing fast across the state under a partly to mostly sunny sky, with late morning readings already in the upper 80s and lower 90s. Dewpoints remain oppressive in the mid to upper 70s, pushing heat indices well into the upper 90s and low 100s even before midday. Isolated to scattered thunderstorms are still expected to develop mainly across the northern and eastern half of the state during the afternoon hours, with rain chances around 20–30%. While widespread storms are not expected, any cell that does form will be capable of brief downpours, gusty winds, and lightning.
INCREASINGLY DANGEROUS HEAT THROUGH MIDWEEK
The upper ridge is building in from the northwest and will continue to suppress storm activity for much of the state while dialing up the heat. Monday and especially Tuesday look to be the hottest days of the period, with highs reaching the mid to upper 90s. With continued high humidity, heat index values will approach or exceed 105°F in many locations. A Heat Advisory is likely to be required for portions of the state, particularly on Tuesday. Expect only isolated afternoon storms through this stretch, with the highest rain chances across the southeast, where the ridge’s influence is weaker.
HEAT ADVISORY FOR WEST CENTRAL ALABAMA MONDAY
The National Weather Service has issued a Heat Advisory for Monday from 11 AM to 8 PM CDT for five northwest Central Alabama counties: Marion, Lamar, Fayette, Winston, and Walker. Heat index values in these areas are expected to reach as high as 106°F, creating a heightened risk for heat-related illnesses. This advisory emphasizes the need for frequent breaks, hydration, and caution during outdoor activities—especially for those working outside or involved in strenuous exertion. This could be the first of multiple heat alerts this week as oppressive humidity and rising temperatures persist.
HUNTSVILLE ISSUES HEAT ADVISORY FOR MONDAY AS WELL
A second Heat Advisory has also been issued for northwest and north-central Alabama, including Florence, Muscle Shoals, Decatur, Huntsville, Cullman, and extending into southern Middle Tennessee, from 11 AM to 8 PM CDT Monday. Heat index values in this region are expected to peak near 107°F, adding to the growing heat threat across the state. This advisory, coupled with the one already in effect farther west, underscores the widespread nature of the dangerous heat Monday. Residents in these areas should take all necessary precautions to stay cool, hydrated, and limit outdoor exposure during peak heat hours.
SEVERE WEATHER POSSIBLE MONDAY IN THE NORTHEAST
While most of the state will be baking under the ridge Monday, a disturbance brushing the northeastern corner of the state could trigger a few strong to marginally severe thunderstorms. The Storm Prediction Center has included far northeastern Alabama in a Marginal Risk (Level 1 of 5) for severe weather, mainly for the possibility of damaging downburst winds. Any strong storms that do develop would be most likely in Cherokee County and surrounding areas during the late afternoon and evening hours.
SOME RELIEF POSSIBLE BY LATE WEEK
As we head into the second half of the week, the ridge may begin to retrograde slightly westward or flatten, opening the door for slightly better storm coverage—particularly by Friday and Saturday. Temperatures may remain hot, but increasing clouds and moisture could help cap the peak heat indices somewhat. There are also indications that deeper tropical moisture from the Gulf could begin nudging northward, especially into southern and southeastern Alabama, raising the chance of more numerous afternoon and evening storms by the weekend.
