Area Forecast Discussion National Weather Service Huntsville AL 1042 AM CDT Mon Jun 23 2025 ...New NEAR TERM, SHORT TERM... .NEAR TERM... (Rest of Today and Tonight) Issued at 1042 AM CDT Mon Jun 23 2025 Under surface high pressure paired with ridging aloft, area temperatures have already managed to climb into the low to mid 80s by 9 AM this morning. Subsidence under high pressure will only further support continued warming throughout the day with afternoon highs forecast to peak in the low to mid 90s. SE flow along surface high pressure centered just to our NW will maintain our high dewpoints in the high 60s to low 70s through the afternoon. Together the high temps and high dew points will push our apparent temps near and just above 100 this afternoon. With the highest apparent temperatures being seen in NW AL, a Heat Advisory is in effect for Lauderdale, Colbert, and Franklin AL through 7 PM this evening. Regardless of heat products or not today, it will be important for everyone to practice proper heat safety as our heat risk remain elevated in moderate (2/4) and major (3/4) across the area. Make sure to stay hydrated and protect yourself from the sun. If possible shift outdoor activities to the this evening and make sure to remember pets and children when planning for the heat. A few diurnal thunderstorms will be possible across the area with the main concerns being heavy rainfall and frequent lightning. Storms will dissipate as the sun sets with the loss of surface heating. No significant changes will take place overnight as the upper level ridging maintains its hold on the TN Valley. Low will only drop into the mid to low 70s before quickly ramping back up for another hot day on Tuesday. && .SHORT TERM... (Tuesday through Thursday) Issued at 1042 AM CDT Mon Jun 23 2025 The hottest temperatures of the summer thus far will be seen in the short term as high pressure retrogrades slightly from Tuesday to Wednesday placing the high pressure center in close proximity to the TN Vally. With continued SE flow keeping our dew points elevated, the close proximity to high pressure will allow our temperatures to nudge into the mid to potentially upper 90s on Tuesday and Wednesday. In response, our heat index values will again be near and potentially above Heat Advisory criteria both Tuesday and Wednesday. Thus, a Heat Advisory will be issued for the whole area for both days. Please make sure to hydrate and seek protection from the sun for yourself, pets, and kids. In addition to heat, a weak low pressure pressure system will pass over the FL Peninsula from Wednesday to Thursday. A few shortwaves look to ripple from east to west along and ahead of this feature across the TN Valley along the southern periphery of high pressure. This will provide just enough support for low (10-30%) rain and storm chances Wednesday and Thursday afternoon. While storms will have plenty of CAPE to work with, a lack of shear will dissuade any widespread severe potential. Rather a few strong storms may be possible with heavy rain and gusty winds being the main concern. && .LONG TERM... (Wednesday night through Sunday) Issued at 1036 PM CDT Sun Jun 22 2025 The heatwave will continue late this week, with potentially major impacts from heat persisting Thursday and Friday as the center of the ridge won't budge much over the Mid South. This will mean hot/humid conditions each day, with highs again in the mid to potentially upper 90s. For this reason, would expect additional Heat Advisories over part or all of the area through the end of the work week. One feature of interest will be an area of low pressure moving into Florida/Georgia by Friday. This would potentially bring some cloud cover and at least a low chance of showers/storms (20-40%) during the afternoon hours. The convection won't change the heat impacts a whole lot, but temperatures could end up being a tick lower, especially on Friday. As this low pivots further to the west on Saturday and Sunday, higher chances for showers/storms will return to the forecast (50-70%). The added cloud cover and higher rain chance may temper the heat risk somewhat heading into the weekend. && .AVIATION... (12Z TAFS) Issued at 640 AM CDT Mon Jun 23 2025 VFR weather is forecast for the KMSL and KHSV terminals into the late night. Broad surface high pressure to our east will provide a light SE flow over the area into the early evening. Daytime heating will produce mainly fair weather cumulus in late morning and this afternoon. Although isolated showers and thunderstorms could develop this afternoon, chances for them is too low for an inclusion in the TAF. With clear skies and light winds tonight, the formation of fog is possible late in the TAF. With higher confidence, did include MVFR fog at both terminals. && .HUN WATCHES/WARNINGS/ADVISORIES...
