UPDATE. For 12Z Aviation.
SHORT TERM. /Updated at 0340 AM CDT Sun Jul 25 2021/
A deep layer ridge will continue to build and expand over the region. At the same time a frontal boundary will begin to slide south through the Ohio Valley. While the front remains well north of the area, there will be enough convergence ahead of the the front that coverage of showers and storms will increase through the afternoon. Right now only will go with a high chance of scattered showers/storms but may need to increase rain chances once convection begins. Activity may continue through Midnight, then decrease and another round of fog potentially develops. The high amounts of low- level & surface moisture will result in low to mid 70s dewpoints. This will cause heat indices to range from 100-104 degrees. Some spots may see brief instances near Heat Advisory criteria this afternoon, but at this time appear isolated enough to forego issuance of an Advisory. Trends will be monitored closely.
As we move into Monday the ridge remains and we will be a few degrees warmer especially in the west. Will increase confidence in the HWO for excessive heat as we could range from 102 to 106 in the heat index values as early as 11 AM. Convection probabilities (chance to likely) , especially north, may reduce some of the widespread coverage, but confidence is increasing. An advisory may need to be issued this time tomorrow.
LONG TERM. /Updated at 0340 AM CDT Sun Jul 25 2021/
Monday night through Saturday.
Warm and humid weather pattern will persist through the upcoming week.
A lingering frontal boundary will slowly push southward through Central AL on Tuesday. Considering the moisture in place, I would expect a higher coverage of afternoon thunderstorm activity with boundary forcing in the area. The biggest impact, however, will be the warm temperatures coupled with the high moisture content of this airmass. Forecast highs are expected to be in the 90-95 degree range on Tuesday with dewpoints in the mid to upper 70s. This will result in heat index values exceeding 100 degrees for almost all of Central AL. There will be several locations that could reach 105-107 degree heat indices, so I'll be adding heat impacts to the hazardous weather outlook for Tuesday. There's some uncertainty on just how widespread the precip could be, which could impact the temperatures, but it's likely that most of the area will reach into the triple digit heat indices.
The frontal boundary is expected to push across the southern portions of Central AL or just to our south Wednesday into Thursday. The amplified ridge across the Mountain West begins to build in across the northern half of Central AL around this same time. It's important to note that while the frontal boundary will push through, this really isn't a cold front - temperatures on the north side of the boundary will likely still be in the mid 90s. The ridging continues to build Thursday through Saturday as the boundary lingers to our south. There could be some isolated to scattered thunderstorms across the south, but the northern portions of Central AL will probably see enough influence from the ridge to see a significant decrease in convective activity compared to the last few weeks. High temperatures Wednesday through Saturday are forecast to be in the low to mid 90s with dewpoints remaining elevated. The saturated grounds from recent rainfall will likely help keep dewpoints elevated, which will result in afternoon heat indices remaining in the triple digits for most of the week. While confidence is low that we'll see widespread heat indices exceed 105 degrees (criteria for heat advisory), I think the prolonged nature of the 100-105 heat indices that are currently forecast could lead to impacts to vulnerable groups; therefore, I'll add a lower confidence mention in the hazardous weather outlook for heat impacts through at least Thursday.
AVIATION. 12Z TAF Discussion.
MVFR/IFR fog has not been as widespread this morning and generally limited to ASN/ANB/EET/ and TOI. This should quickly burn off by 14z. Another round of showers and storms this afternoon. Included Prob30/VCTS at all sites, expect KTOI. Here chances are too low to include at this time. Will not mention any fog yet in the TAFs for Monday morning as it will be highly dependent on rain placement this afternoon.
A warm and moist airmass will persist across Central AL through the weekend and much of the upcoming week. Min RHs will remain elevated with scattered to numerous diurnal thunderstorms today through Tuesday. Rain chances decrease as we head towards midweek, but min RHs remain elevated.
