Area Forecast Discussion National Weather Service Huntsville AL 244 PM CDT Wed Jul 30 2025 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 244 PM CDT Wed Jul 30 2025 Several areas of showers and thunderstorms have developed across the TN Valley this afternoon. One forcing mechanism is a convergence boundary draped from northeast TN down through northwest AL. Near-stationary storm motions and the lack of shear have led to numerous storms generated by nearly perfectly-round outflow boundary collisions. This activity has begun to drift into our southern middle TN counties. The second forcing for ascent near our area is a localized cyclonic rotation over I-65, evident in satellite-derived precipitable water imagery. PW values over 2" east of I-65 are being pulled northward by southerly winds, whereas west of I-65 lower PWs near 1.5" are being pulled southward by north/northwesterly winds. I-65 is almost perfectly in the middle of this, and the convergent rotation (on a relatively large scale) is providing localized forcing for ascent in this vicinity. Also split in the west vs. east bifurcation is the responsible factor for the gusty wind potential. In the drier west, DCAPE values exceed 1400 J/kg due to steeper low- and mid-level lapse rates. In the more moist east, PW values over 2" will allow for hydrometeor loading and strong downdrafts. For both, the potential for slow, nearly stationary storms and strong downdrafts of 40-50 mph will be the primary threat this afternoon and evening. Loss of daytime heating should result in loss of convective coverage after 7-8 PM, unless fueled by localized outflow boundary interactions. Not to be outdone, heat index values have reached over 105 for most of the area. At least all three ASOS sites in HSV, MSL, and DCU have reached or exceeded 105, with several AWOS sites also cresting into heat advisory criteria. Afternoon dew point mixing has decreased the coverage of sites currently at 105. Temperatures will fall overnight into the low to mid 70s. && .SHORT TERM... (Thursday through Saturday) Issued at 1102 AM CDT Wed Jul 30 2025 As much as we have hoped for a pattern shift later this week, it looks as though the ridge aloft is taking its sweet time translating westward. As a result, the heat advisory has been extended an additional 24 hours until 9 PM on Thursday for heat index values of 105-109 F. Diurnal shower and storm development is anticipated once again, with not as high of a ceiling for strong storms as today. However, the additional cloud cover and convection should be delayed until later in the afternoon, similar timing to today, which would allow most of the area to heat up into the heat advisory criteria. All indications are that the pattern shift should take place on Thursday. A cold front currently stalled over the Midwest will sag southward. Timing this front is fairly inconsistent depending on which guidance source is referenced. Cluster analysis of global ensemble guidance in DESI indicates a 60% chance the front pushes into the TN Valley on Thursday evening, bringing the heavier rainfall through at that time. The other 40% shows the front slowing a bit and moving through early Friday morning. Whichever way you roll the dice, Thursday should be wetter with pre-frontal convection (50-70% chance), and then we cool down on Friday with high temps in the upper 80s to maybe 90. Shortwave troughs rippling around the ridge will provide additional forcing for ascent on Friday behind the front, bringing another day of 50-70% PoPs. We cool off more on Saturday with highs only in the mid 80s and afternoon rain chances peaking between 30-50%. The lower end PoPs in the range will be areas west of I-65, where the suppression of the upper level ridge will result in less shower coverage. && .LONG TERM... (Saturday through Tuesday) Issued at 1050 PM CDT Tue Jul 29 2025 An upper level trough will be swinging over the northeastern US by the weekend, but another will be on its heels for early week. Meanwhile, a series of shortwaves look to traverse the Midwest and Ohio/Tennessee Valley regions during this time. At the surface, a cold front is expected to have pushed south of the local area on Friday. This will likely eventually stall near the Gulf coast through Tuesday. An inverted trough may set up over the Tennessee Valley for Sunday, but high pressure will build over the northeast by early next week. Overall, sensible weather will comprise of daily chances of showers and storms, with the highest chances during the weekend then tapering off a bit for Monday and Tuesday. While there will likely be ample instability for thunderstorm development, guidance suggests that bulk shear values will mostly remain below 30 knots. Thus, severe weather is not anticipated at this time. The good news is that temperatures are forecast to be more mild than we've seen recently, with highs topping out in the 80s through Monday. Although, by Tuesday, as the aforementioned high pressure begins to build southwest into the region from the northeast, temperatures are expected to be a touch warmer. So, hang in there, some relief from the heat is on its way! && .AVIATION... (18Z TAFS) Issued at 1228 PM CDT Wed Jul 30 2025 Fairly ordinary summertime day for aviation interests. Afternoon and evening shower and storm development may result in some AWWs for terminals. Otherwise, light and variable winds resume overnight with fog not expected to impact terminals. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...Heat Advisory until 9 PM CDT Thursday for ALZ001>010-016.
