Current-Tonight-Fri...isolated to WDLY SCT showers/lightning storms over the local coastal waters may occasionally brush the coast in the SSE steering flow this morning. Otherwise continued mild and muggy with temps and dewpoints generally in the 70s areawide. The Atlantic ridge axis will remain near to just north of ECFL thru late work-week. This will continue a SERLY (southeasterly) flow across the area. Morning winds 5-10 mph increasing to 10-15 mph along the coast with sea breeze passage. Remaining moist for one more day with PWATs (Precipitable Waters) surging north of 2 inches, then drier air moves into the area on Fri. Keeping 50-70pct for Probability of Precipitation across the coverage warning area today (highest inland from the coast), then chances decrease into Fri (20-30pct coast & 30-50pct interior). Aloft, height rises occur in the mid-levels as ridging builds westward toward the peninsula, though still rather cool temps aloft forecast (-7C to -9C at H500). Primary storm impacts remain occasional to frequent cloud-to-ground lightning strikes, gusty winds locally 40-50 mph, and torrential downpours - minor/nuisance flooding possible for locales that have recently seen multiple rounds and other prone low-lying areas.

Increasingly hot and humid conditions, with highs in the L90s today and L-M90s on Fri. Peak afternoon heat indices range from 102-107 degrees each day. Overnight lows will continue in the 70s with conditions humid.

Sat-Tue...The broad mid-level ridging builds over the peninsula on Sat, then pushes into the Gulf Sunday and across the Deep South Mon- Tue, resulting in mid-level height decreases across the peninsula late in the period. At the surface, weak ridging settles across the area Sat-Sun, then into south FL Mon-Tue. Heat and humidity continue to build across the area into the weekend and on Monday with highs in the L-M90s, falling slightly to the L90s everywhere on Tue. Cannot rule out a few U90s over the interior this weekend. Have presently capped peak heat indices in the grids at 107F for the extended, but potential is there for some readings above 108F which could reach Heat Advisory thresholds - esp across the interior. Any relief from the heat may come from sea breeze passage near the coast and scattered afternoon/evening showers/storms, but coverage will be lower this weekend (highest across the interior). Probability of Precipitation forecast to increase gradually early next week as deeper moisture may move back into the area. Overnight lows continue in the 70s with conditions muggy.

Today-Mon...The Atlantic ridge axis remains fixated near to just north of the local waters into late week, slowly sliding south into early next week. A persistent ESE/SE flow thru Sat, becoming light offshore Sat-Sunday nigheights - though daily sea breezes will transition flow onshore during the afternoon/early evening periods this weekend. Wind speeds typically at or below 15 kts. Seas primarily 2-3 ft. Winds/seas locally higher in the vicinity of showers and lightning storms. Fairly high precipitation coverage again, today, then drier air moves into the area Fri-Sunday (below normal rain chances), then slightly increasing chances again on Mon. Primary storm threats remain cloud-to-water lightning strikes, gusty winds, and heavy downpours.
