Area Forecast Discussion National Weather Service Huntsville AL 648 PM CDT Tue Jun 26 2018 .UPDATE... For 00Z TAFS. && .NEAR TERM...(Tonight) Issued at 225 PM CDT Tue Jun 26 2018 Upper shrtwv continues to translate ewd out of the Midwest states and into the mid TN/OH Valley regions this Tue afternoon. Most of the shower/tstm activity associated with the shrtwv is north of the local area across nrn mid TN into cntrl KY. A few iso cells have developed across the cntrl TN Valley in response to latent heating. These tstm cells though have been short lived though given the lack of any deep layer shear. Generally xpct this pulse like convection to continue into the early evening hrs, as the shrtwv to the north continues to advance ewd. Certainly cannot rule out a strong tstm or two given the abundant SBCAPE over 4K J/kg in place thru the early evening hrs, although this prob is fairly low. Overall conditions should begin to clr heading into the late evening period, under partly cloudy skies. It should be another mild night heading into the early morning hrs Wed, as lows fall mainly into the lower/mid 70s range. Cannot rule out a little bit of patchy fog mainly in the wind sheltered valley locations and near bodies of water, but this prob is also fairly low. .SHORT TERM...(Wednesday through Thursday) Issued at 225 PM CDT Tue Jun 26 2018 Another seasonably hot and humid day is xpcted on Wed, as afternoon highs again climb mainly into the lower 90s. Heat indices may also climb just above the 100F mark for a couple of hrs, especially in areas which do not receive any rainfall. The upper shrtwv to the north will continue to translate ewd and may actually dig a bit further to the south closer to the mid TN Valley. This may in fact increase rain chances just a bit on Wed, as slightly better mid/upper forcing spreads into the area from the NW. Showers/tstms may in fact linger into the late evening period Wed night before diminishing, leaving partly/mostly cloudy skies in place. Temps early Thu morning will again be rather mild, with lows predom in the lower/mid 70s. Upper ridging out of the Plains states then begins to build ewd into much of the region starting Thu. This should result in slightly less chances for showers/tstms while afternoon highs increase a degree or two. Afternoon highs Thu may climb as high as 93-94F in some spots, while associated heat indices reach 105-107F in some locations, especially in NW/N cntrl AL. A Heat Advisory may be warranted on Thu. .LONG TERM...(Thursday night through Monday) Issued at 225 PM CDT Tue Jun 26 2018 An upper-level ridge will continue to remain the dominant weather feature across the region, promoting hot and humid conditions across the Tennessee Valley late this week into the weekend. There are some subtle differences between the longer range models regarding the intensity of the ridge and subsequent warming, with the ECMWF and Canadian solutions favoring a slightly stronger/warmer solution. The GFS hints at the possibility of a very weak Gulf low moving north into Central Alabama on Friday -- perhaps resulting in more cloud cover and diurnal convection Friday and Saturday. Regardless, it will feel quite toasty outside, with highs peaking in the low to mid 90s across the Valley. A light SW flow will maintain this very moist, tropical air mass in place across the region, as dewpoints will remains close to the mid 70s. As a result, progged Heat index values on Friday may once again reach or exceed Advisory criteria, peaking in the 105-108 degree range. Will need to continue to monitor this trend in the coming days. The center of the upper ridge will gradually shift to the north and east over the Carolinas. While SW flow will remain in place, temperatures should be a degree or two cooler, placing Heat Index values in the 100-105 degree range, just below Advisory criteria. With the deep moisture in place, the threat for scattered thunderstorms (a few strong) will be possible each day, mainly in the afternoon and evening hours. Will have to watch very late in the period (early next week) should the ridge flatten slightly, allowing a few shortwaves to propagate into the Ohio Valley (and, thus, for any MCS activity to approach the region from the north and west). For this reason, have trended slightly higher with PoPs on Monday and Monday Night, with the higher values favoring the northern zones. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 648 PM CDT Tue Jun 26 2018 For the start of the TAF, isolated showers were in the vicinity of the KHSV terminal. An outflow boundary was also moving southward towards far northern Alabama, east of I-65. This boundary may help with the formation of new convection, mainly east of the MSL/HSV terminals through ~27/0200Z. VFR weather otherwise is expected for the TAF. S-SW winds around 5kt should become light/variable after dusk. Light winds at daybreak should become SW and increase in the 10-15 kt range by noon. Another system approaching from the NW could bring more shower chances to the region Wed afternoon. Given uncertainties, went with VCSH for the afternoon hours. Prob30 and/or prevailing showers and t-storms could be added in later TAFs if better model agreement is realized. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
