DISCUSSION Updated for latest aviation discussion below.

AVIATION 12Z issuance...VFR conditions will continue through the day.

Winds will remain light out of the east. BB 03

PREV DISCUSSION issued 448 AM CST Wed Nov 20 2019 NEAR TERM Now Through Wednesday night ... Another quiet day is on tap as high pressure dominates the forecast today. A Mid-level shortwave ridge over the central US will strengthen and slowly drift east as the next system to bring us rain moves into the Pacific Northwest. At the surface, high pressure over the central gulf will shift over central Alabama. Strong subsidence is expected to continue leading to another clear sky day with light winds. The 00z LIX RAOB still showed mid-level backing with a solid subsidence inversion which will lead to low-level insolation. Given this and the models rough week with high temperatures, it felt safe to bump daytime highs into the low to mid 70s. Lows will remain in the 40s inland to 50s along the coast as minimal to no moisture advection will keep dewpoints in a rather stable diurnal state. BB 03 SHORT TERM Thursday Through Saturday ... Thursday into Friday, an upper ridge over the Eastern Conus begins to de-amplify as a shortwave trough swings south over the Great Lakes Region. A upper low over the Desert Southwest shifts east, taking a significantly slower progression than yesterday's 00z guidance.

This slows the eastward progression of a cold front over the Plains towards the forecast area. Onshore flow returns to the region Thursday, beginning the process of bringing Gulf moisture back to the forecast area. Subsidence from the upper ridge will continue to bring temperatures above seasonal norms Thursday into Friday, with low to mid 70s expected Thursday, mid to upper 70s Friday. Lows in the 50s expected Thursday night.

Friday night through Saturday, a weak to moderate cold front moves across the forecast area as the Southwestern Conus upper low moves east. Guidance has slowed down in the timing of the front's passage, as the Southwestern upper low takes a more leisurely track. The GFS has slowed the most, the NAM the least, and the ECMWF in the middle. Fropa with yesterday's guidance was in the 12z + - time frame, whereas the latest 00z guidance is advertising a 15-18z + - frontal passage. Have slowed yesterday's timing down to a 15z + - timing, leaving any more timing changes to following issuances. With that said, general rain is still expected with enough instability over open Gulf waters for thunderstorms to mix in late Friday night through Saturday morning. With the slightly slower passage of the cold front, sounding indicate enough of an increase in instability ahead of the front to warrant the addition of isolated thunderstorms over land area Saturday morning, mainly near the front. Instability will still be limited, limiting any strong storms much less marginally severe. With the slower passage, am also expecting more of the forecast area to see above seasonal temperatures Friday night, with low temperatures generally in the low to mid 60s expected. With cooler air overspreading the forecast area behind the front's passage Saturday, high temperatures ranging from the low to mid 70s southeast of the I-65 corridor are expected, with temperatures tapering downward to the low to mid 60s northwest of I-65.

16 LONG TERM Saturday Night Through Tuesday ... Temperatures around seasonal norms return to the forecast area for the latter half of the weekend as post-frontal cool air overspreads the area. A weak upper ridge quickly passes over the Southeast early in the coming week, bringing a return of above seasonal temperatures back to the forecast area. Onshore low level flow returns to the forecast area by Tuesday, with guidance advertising another front crossing the region Tuesday night into Wednesday.

16 MARINE... Light easterly flow will develop this afternoon as the surface high pressure moves north across central Alabama. Winds will eventually become more onshore as the week progresses in ahead of an advancing cold front. Seas and winds will likely increase as the pressure gradient strengthens ahead of the front Saturday. A few showers and storms could be possible ahead and along the front.

Behind the boundary, moderate northwesterly flow will develop.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
