141 FXUS64 KBMX 110028 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 728 PM CDT WED AUG 10 2016 .UPDATE... For 00Z Aviation. && .DISCUSSION... Broad surface low along the Gulf coast continues to spin tropical moisture up into central Alabama. The trend over the last couple days has been for showers to develop around 10 am and reach peak coverage around 4 pm. Today has shown a marked decrease in thunderstorm formation in Alabama (actually, as of 3 pm, I don't think we've had one yet). If recent form holds, the showers should decrease this evening, with a chance of sprinkles or drizzle developing late. Models continue their previous trend of drifting the low to the west and northwest through the next few days, before getting absorbed into a frontal system. The moisture influence of the system is large enough that we will continue to have enhanced rain chances for several more days. Once we get into the weekend, and especially into next week, conditions are likely to become more typical for late summer. Nothing obviously major heading our way, synoptically. /61/ && .AVIATION... 00Z TAF Discussion. Large cyclonic spin covers much of central Alabama thanks to broad low pressure. Several showers remain across the region and kept the mention of vcsh in until 02z with diminishing trend expected after sunset, although a few showers could be around almost any time. Along with this cyclonic flow, ample tropical moisture and isentropic lift will be present overnight. Most locations will experience MVFR ceilings between now and 06-08z then IFR ceilings and possibly some drizzle. This forecast is heavily persistence oriented as expect the same repeat conditions on Thursday. With the clouds around, highs have been held a bit lower and instability is not too high. Therefore, did not mention any thunder at this time. 75 && .FIRE WEATHER... A tropical air mass will be present through the end of the week. This will result in high rain chances each day. Critical fire weather conditions will not occur this week. && .PRELIMINARY POINT TEMPS/POPS...
