734 FXUS64 KHUN 170349 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 1049 PM CDT Mon Jun 16 2025 ...New NEAR TERM, SHORT TERM, LONG TERM... .NEAR TERM... (Rest of tonight and Tuesday) Issued at 1049 PM CDT Mon Jun 16 2025 Strong storms have pushed northeastward along an outflow boundary, out of our County Warning area this evening. Stratiform rain remains over portions of northern Alabama and southern middle Tennessee and will likely continue through the next couple of hours ahead of an upper level trough dipping through the Mississippi Valley. Dry weather is forecast to return to the area briefly overnight, however, redevelopment of showers is forecast by around 10-11Z through NW AL. Showers should generally stay contained to NW AL through the morning hours before increasing in coverage as well as intensity through the afternoon as a result of diurnal heating. Weak shear should dissuade organized severe convection, however, sufficient CAPE as well as low level lapse rates will support gusty winds and frequent lightning in strong storms throughout the afternoon hours. In addition to the wind and lightning threat, a risk a flash flooding also exists Tuesday through Wednesday morning as storms are likely to train over the same locations and produce moderate to heavy rainfall. Therefore, expect at least ponding of water in low lying areas and areas of poor drainage. Hazardous road conditions may also be observed in areas where strong storms form and rainfall rates are high. && .SHORT TERM... (Tuesday night through Thursday) Issued at 1049 PM CDT Mon Jun 16 2025 Shower and thunderstorm chances should begin to gradually decrease after sunset on Tuesday and officially come to an end around midnight. Low temperatures are forecast to drop to the upper 60s to lower 70s under mostly cloudy skies. Cloud cover, along with lingering breezy winds, should deter fog formation. As the aforementioned upper level trough axis continues to slowly move eastward, shower and thunderstorm chances continue Wednesday with coverage and intensity peaking during the afternoon hours due to diurnal heating. Soils will be saturated throughout most of the Tennessee Valley, allowing an increased flooding risk with any storms that move through the area as rainfall rates are expected to be high with stronger storms. Sufficient instability as well as shear will allow for strong storms to be possible again with gusty winds, small hail, and frequent lightning to be the main hazards. Despite not being officially outlooked for severe weather at this time, a severe storm cannot be ruled out with the primary threat of damaging winds. Wednesday night into Thursday, WSW flow allows drier air to filter in and limited rain chances through the area as lows drop into the upper 60s to lower 70s. This break in rainfall will be short- lived, however, as rainfall once again returns on Thursday as a cold front, stemming from a parent low pressure system in the northeast, approaches the area from the northwest. Strong storms along the front, once again, cannot be ruled out with the primary concern of gusty winds as well as frequent lightning. && .LONG TERM... (Thursday night through Monday) Issued at 1049 PM CDT Mon Jun 16 2025 After the frontal passage Thursday night, dry air filters in from the northwest. A ridge of high pressure is forecast to build in from the west this weekend, allowing a warming trend through the weekend into early next week. Daily high temperatures are forecast to warm into the low to mid 90s by Sunday and Monday with heat indices near 100-105 degrees. If trends continue on the track they are on, heat products may be considered if heat indices are forecast to exceed 105 degrees. Overnight lows are forecast to drop into the low to mid 70s, which will not provide much relief from heat. Along with the heat concern, daily thunderstorm chances (30% or less) continue- peaking during the afternoon hours. However, heat will be the primary concern heading into the weekend into early next week. Those without effective cooling and/or adequate hydration will likely be affected in addition to heat sensitive industries and infrastructure. && .AVIATION... (00Z TAFS) Issued at 638 PM CDT Mon Jun 16 2025 Showers are forecast to continue to be within the vicinity of both KHSV and KMSL through the next several hours before dry weather returns overnight. MVFR conditions are forecast early Tuesday morning as lowered ceilings move into the Tennessee Valley. MVFR conditions should persist through tomorrow along with additional shower/thunderstorm chances through the day, peaking during the afternoon hours. && .HUN WATCHES/WARNINGS/ADVISORIES...
