The onshore east to northeast winds did its "dirty work" Wed. with extremely heavy rain in localized coastal areas while amounts near & especially west of Highway 301 were far less & -- in some cases -- none at all. Photos below are from Richard in St. Johsn Co. looking east toward a late afternoon waterspout....Martha Nourse, Vilano Beach as a squall approaches the coast....3rd photo is from Shelby Ellis, S'side street flooding. A few rainfall reports:

I-295/Gate Parkway: 7.02"

San Marco: 4.26"

Orange Park: 3.09"

St. Augustine: 2.07"

Arlington: 1.49" (local Arlington reports 3")

Mayport: 1.37"

Jax Beach: 0.98"

JIA: 0.44"

Scattered showers will continue to move west/southwest off the Atlantic through Thu. but will be less organized/less persistent so amounts will be less overall despite brief downpours. Breezy to windy onshore east/northeast winds will blow for another day creating a high rip current risk at area beaches. Nice weather for Fri./Sat. though temps. will be hot with high humidity. Afternoon highs will reach the mid 80s to around 90 degrees.

Radar imagery below courtesy S. Fl. Water Management District:

The weekend weather still looks to be dominated by a surge of tropical moisture combining with a cool front & weak low pressure (possibly a tropical disturbance) to produce heavy rain & storms across the First Coast. So it looks like September will live up to its wet reputation in what is climatalogically the wettest month of the year (averages 8.19").

The question is the exact timing. Sat. should be the "pick day" of the weekend but hot & humid. The sea breeze will likely set off a few showers & storms but rain will be only widely scattered. Sunday is the day in question. It appears rain & storms will increase in the afternoon & become widespread Sun. night into at least part of Mon. Depending on how things evolve (temps., moisture, instability), rain could be very heavy & there might be a severe storm threat.

From NASA:

What is Solar Weather?
solar weather is the changing conditions in the space surrounding Earth that is affected by activity on the Sun.
