Area Forecast Discussion National Weather Service Birmingham AL 157 PM CDT Fri Sep 22 2017 .SHORT TERM... Through Tonight. Isolated to scattered convection has already developed generally along and south of the I-20 corridor early this afternoon. Weak lift associated with the mid and upper level trough/elongated upper low will continue to aid some of this convective development along with leftover mesoscale boundary interactions. Have raised PoPs a bit higher over the eastern counties, as low-level easterly flow is pushing air parcels up and over the higher ridgetops. More robust cu development was already observed on visible satellite. This also lines up well with high-res guidance that has the most development in our central and eastern counties as well. Have raised highs a degree or two for a few locations this afternoon, but temperature forecast is generally on track. Expect convection to dissipate after sunset as typical for summer convection, even though technically this is the first day of astronomical fall. Humid conditions will continue during the overnight hours tonight, with patchy fog expected once again in valley locations and near major rivers and lakes. 56/GDG .LONG TERM... Saturday through Thursday. On Saturday, we have a rather busy looking upper air setup. A piece of energy breaks off from a deteriorating Jose to over the Northern Gulf of Mexico as Maria continues to trudge northward out of the Caribbean toward the East Coast. At the same time a deep trough digs across the Western US leaving a confined area of weak upper ridging near the Mid MS River Valley into the Great Lakes and NE US. Our result over C AL will be low diurnally influenced pops with still status quo temperatures. By Sunday, the upper energy from Jose fizzles further while the low over the Northern Gulf retrogrades toward MS/LA, and Maria moves further northward further constricting the weak ridging to NE US while the West Coast system slowly moves over the Rockies. On Monday we see Jose gone, absorbed into Maria. The system over the Rockies starts to open up pulling the energy over the southern states into it. Only weak flow remains over the Eastern US as Maria monopolizes the flow. The result for C AL Sunday into Monday will be only low pops south/southwest with better chances near the Gulf Coast. Tuesday into Wednesday, the main low associated with the Rockies system moves northeast toward Manitoba. At the same time, ridging fills in over the Gulf behind Maria and starts to creep around into E Conus. During this time, we trend drier across Central Alabama. By the latter half of the week, we see some divergence in solutions as to weather we get a shortwave breaking off of the main Rockies trough as the low pulls away across Canada and a TX/Mexico ridge set up. Or we could get a somewhat flattening out of the ridge but another low digging into the Northern Plains from Canada. Either way, across C AL by the end of the forecast Thursday, we remain on the dry side in advance of a slowly approaching surface front across the US now that Maria is moving away. 08 && .AVIATION... 18Z TAF Discussion. Nothing noted on radar at the moment, but a nice cumulus field has developed. Look for scattered convection today, but expected coverage still only warrants VCTS mention for the afternoon hours. As is typical in the summertime, activity will diminish this evening. Winds will be easterly around 5 kts. Widespread fog is not anticipated overnight. However, some patchy fog is possible near bodies of water and in areas that receive rain today. 19 && .FIRE WEATHER... Isolated to scattered showers and storms are expected through Saturday. Rain chances trend lower Sunday and Monday. Relative humidity values only drop into the upper 40s and 50s. Transport winds remain rather light which will keep dispersion values too. && .PRELIMINARY POINT TEMPS/POPS...
