-- Changed Discussion --
Thunderstorms continue to cross through the northern forecast area staying primarily in Alabama and Georgia. PoPs were bumped up in the current period to match the pattern of precipitation, but from 06Z to 12Z rain chances will remain just at or below 20 percent. High relative humidities will accompany minimum temperatures in the lower 70s tonight. Besides adjusting the PoPs, the previous forecast remains on track.

&& .SHORT TERM [Tuesday Through Wednesday Night]... Weak upper level troughing across the southeast states will continue through the short term period. A weak frontal boundary will sag southward into the area on Tuesday and Wednesday and provide a focus for scattered afternoon convection, mainly across the northern areas on Tuesday and then pushing farther south on Wednesday. Temperatures will remain near the seasonal averages. && .LONG TERM [Thursday through Monday]... A fairly seasonal period is expected with scattered afternoon and evening convection each day. Some days will likely have slightly higher PoPs than others depending on the timing of individual weak shortwaves, which is hard to forecast in the long term. No major synoptic scale systems are expected to impact the area during the period. Temperatures are expected to remain near their seasonal averages. && .AVIATION...

[Through 00z Wednesday] With storms dissipating as the evening continues, VFR conditions will be seen overnight for all terminals. KDHN, KVLD, and KABY are expected to see MVFR Cigs from 09Z to 14Z. After this period VFR conditions will once again prevail. After 18Z tomorrow, the northernmost terminals will have the greatest chance for TSRA to develop, but as of right now only VCSH are included in the TAFs.

&& .MARINE... The subtropical ridge will be the dominant feature across the northern Gulf of Mexico this week, yielding mainly light southwest to west flow and low seas. && .FIRE WEATHER... Red Flag conditions are unlikely this week as RH values will remain above locally critical levels. The combination of deep mixing and somewhat stronger winds aloft will help dispersion values climb above 75 Tuesday afternoon. && .HYDROLOGY... River gauges are expected to remain below flood stage for at least the next several days. && .PRELIMINARY POINT TEMPS/POPS...
