263 FXUS64 KHUN 160214 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 914 PM CDT Tue Jul 15 2025 ...New NEAR TERM, SHORT TERM, LONG TERM... .NEAR TERM... (Rest of tonight and Wednesday) Issued at 914 PM CDT Tue Jul 15 2025 Despite convection boxing us in from the NW and SE, tonight is forecast to be another warm yet benign night. Convection to our NW is forecast to die off as the sunset leaving us with dry conditions overnight. Calm winds and low dew point depressions may allow for some patchy to local dense fog to develop through mid morning. Tomorrow, conditions will heat up across the TN Valley. With elevated dewpoints in the low 70s remaining in place, the slightly warmer temps in the mid 90s will allow heat indices to soar over 100, with locations in NW and north central Alabama seeing the highest apparent temps near and just above 105. For this reason, a Heat Advisory is in effect for NW and north central Alabama from 10 AM to 7 PM. Please make sure to practice proper heat and sun safety. Low rain and storm chances will also be retained tomorrow afternoon with the coverage perhaps slightly better than we have seen the previous days. No widespread severe threat is forecast however any storms that do develop will be capable of heavy down pours, frequent lightning, and gusty winds. && .SHORT TERM... (Wednesday night through Friday) Issued at 914 PM CDT Tue Jul 15 2025 Synoptics will have a much greater influence in the short term forecast as we head into the second half of the work week. Two features will drive our local weather. To our NW paired with a surface low pressure system will drape a cold front across the NE CONUS from Wednesday into the weekend. To our SE, Invest 93L will continue to be pushed west across the Gulf coast as surface high pressure nudges westward into the FL Peninsula. Despite these two synoptic features sandwiching us to the north and south. local impacts will be very familiar. The proximity of these two features will keep tropical moisture trapped in the TN Valley and allow for perhaps slightly higher diurnal rain and storm chances each afternoon. This slight increase will have an impact on our afternoon high temperatures and play into the decision on extending the Heat Advisory. Current forecast highs are in the low to mid 90s each day. Should afternoon showers fire up, we may not reach our afternoon forecasted high each day. Thus, extensions to the Heat Advisory will likely be evaluated on a daily bases through at least Thursday as forecasters have the chance to look at the most recent HIRES guidance regarding high temps, dew points, and storm coverage and timing. && .LONG TERM... (Friday night through Tuesday) Issued at 914 PM CDT Tue Jul 15 2025 Long range models show mid level ridging retrograding across the Gulf coast through the start of next week. This unfortunately will amount to more of the same for the long term forecast. High pressure will keep elevated dew points and temperatures anchored to the TN Valley. This will amount to apparent temps near and just over 100 nearly everyday of the long term forecast. Likewise, daily afternoon rain chances look to remain in the forecast. Around and along the northern edge of the ridge, NW flow may support MCS development in the mid Mississippi and Ohio Valley as we head into next week in. We will be keeping an eye on this trend should dying MCS try to drop into our forecast area. && .AVIATION... (00Z TAFS) Issued at 539 PM CDT Tue Jul 15 2025 VFR will be the prevailing flight category through the TAF period. From 6-12Z, patchy fog is possible across the area, this was not included in the TAF at this time due to low confidence. A TEMPO group for fog may be added in the next TAF issuance. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...Heat Advisory from 10 AM to 7 PM CDT Wednesday for ALZ001>007- 016.
