730 FXUS64 KHUN 061957 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 257 PM CDT Mon Oct 6 2025 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 257 PM CDT Mon Oct 6 2025 Presently our area is situated between a cold front to the northwest and high pressure to the northeast. Moisture is being brought into our area as a result of flow from the high pressure, resulting in a low chance (10-20%) of isolated showers and high cloud coverage. Due to lack of forcing, there is low confidence in thunderstorm formation in the area through the remainder of the day. Through the night, the chance of precipitation will increase from low (10-20%) to medium chances (30-60%) by sunrise tomorrow particularly in the northwestern portion of the CWA as a result of the approaching cold front. With the approaching cold front, there is a low chance of some weak storms embedded in the ongoing showers in our northwestern counties early tomorrow morning. Low temperatures tonight will remain warm with the area experiencing upper 60s and lower 70s due to insolation from high cloud coverage. Tonight, some areas will likely experience low temperatures greater than 70 degrees especially in the western counties with the potential for setting some record high lows. The record low for today in Huntsville is 73 and the record low for tomorrow in Huntsville is 70. The record low for today in Muscle Shoals is 73 and the record low for tomorrow in Muscle Shoals is 74. && .SHORT TERM... (Tuesday through Thursday) Issued at 1016 AM CDT Mon Oct 6 2025 Unfortunately Tuesday will be another dreary day however an approaching cold front will provide enough support for heavier rain and perhaps a few storms. The approaching front, currently draped across the Plains, looks to move through the TN Valley overnight from Tuesday into Wednesday. Along and ahead of this front, rain chances will increase through the day. The ample moisture present from previous days of ESE flow will support periods of moderate to heavy rainfall however HIRES model guidance maintains our overall QPF near or just above an inch, highest in NW AL. Thus, we are not anticipating any major flooding concerns. As the front approaches instability will also increase from the SW. A few hundred J/KG of CAPE looks likely tomorrow afternoon. With the better shear retaining close proximity to the front, this will create a narrow window tomorrow evening where favorable shear and CAPE may overlap to produce some stronger storms with heavy rainfall from convective rain rates and gusty winds being the main concern. Instability will decrease within a few hours of sunset decreasing the concern for any stronger storms overnight. HIRES models show a majority of the precip ending with the progression of the front to our SE by Wednesday morning. Despite this, cloud cover will likely remain for most of the day. The combo of cloudy conditions and northerly winds brining in cooler air will moderate temperatures on Wednesday with highs near 80. We will remain in close enough proximity to retain partly to mostly cloudy skies on Thursday, especially in NE AL. Fortunately only low (~10%) rain chances will be present on Thursday, however this could increase especially in NE AL if the front slows down. Clouds will again help to moderate temperates with highs near normal in mid to high 70s. && .LONG TERM... (Thursday through Sunday) Issued at 920 PM CDT Sun Oct 5 2025 Consensus guidance from the latest suite of global models suggests that an initially weak mid-level shortwave disturbance in WNW flow aloft will gradually develop into a stronger trough across the southeastern CONUS over the course of the long term period. Although we will likely remain on the dry side of the trough, low-level moisture and convergence will both be sufficient for a continuation of clouds and a few light showers on Thursday and perhaps Friday, as well. However, increasing deep- layer northerly flow (to the west of the mid-level trough and a developing area of surface low pressure off the southeastern Atlantic Coast) will eventually advect a drier airmass into the region Saturday/Sunday, with only a few showers possible in the higher terrain to our northeast. Through the period, highs will be in the m-u 70s, with lows in the 50s. && .AVIATION... (18Z TAFS) Issued at 1201 PM CDT Mon Oct 6 2025 MVFR ceilings will be in place at both terminals at the start of the period. Ceilings look to lift to VFR late in the afternoon and remain so through the night. Gusty ESE winds will also be present through the TAF with highest gusts near 20 KTs at the start of the period, decreasing slightly to around 15 KTs later this evening. A passing cold front tomorrow will create complicated TAFS after 12Z with low ceilings and rain for a majority of the day. Current forecast has IFR to MVFR ceilings arriving around sunrise with light showers possible. Heaviest rain and lowest ceilings look to be beyond this TAF period and will be addressed in future TAF issuance. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
