The episode as NWS JAX wrote it up.
Southwest steering flow brought a more dominant west coast sea breeze regime. A few strong to severe storms developed along outflows and mergers in the afternoon and evening. Convection was fueled by elevated mean layer moisture and diurnal instability.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Aug 1, 1:02 PM EST, 2 hours 16 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 202 PM EDT MON AUG 1 2016 .SHORT TERM /This afternoon through Tuesday/... Pattern shift with increasing rain chances as surface ridge weakens over the area and mean layer trough axis deepens down the SE Atlantic coast states. Numerous showers and tstorms will gradually build eastward across our interior Ga zones and the Suwannee River Valley through mid afternoon with more isolated activity forming along the east coast sea breeze over our SE Fl zones where mid level subsidence was slightly stronger under the 1000-500 mb ridge axis. Best chances of late afternoon and early evening convection will be across SE Ga and across inland NE Florida where sea breezes/outflows will converge under an increasingly moist airmass...with convection fading through midnight with loss of heating. Cannot completely rule out a rouge shower across the area after midnight tonight due to mean layer trough axis currently across AL/Western GA positioning and lingering across the local area...but at this time indicated 10% rain chances after midnight with muggy overnight conditions with lows in the mid/upper 70s. Tuesday elevated rain chances continue with a pattern similar to today but with greater coverage as the mean layer trough deepens across the area and the ridge axis shift farther south. A light westerly flow will again bring a more dominant west coast sea breeze regime...with locally heavy rainfall likely with PWATs increasing to near 2.2-2.3 inches across the county warning area by late in the day. Scattered strong to isolated severe thunderstorms will be possible both today and again Tue during peak heating and into the early evening hours. Main convective concerns will be very heavy rainfall given high deep layer moisture content and very weak storm motion. In addition to the heavy rainfall...precipitation loading will also favor strong wet downbursts. Increased cloud cover will temper high temperatures compared to recent days which will generally range in the low/mid 90s with heat index values near 105. Low temperatures will range in the mid 70s inland to upper 70s coast with muggy overnight conditions. .LONG TERM /Wednesday through Sunday/... Forecast area will be on the eastern side of Southern Plains/Gulf Coast Region upper ridge...with another ridge over the western Atlantic...and a weakness over our forecast area. At the surface will have a persistent weak surface trough over ctrl GA and afternoon sea breezes moving inland from the Atlantic and Gulf. Model guidance maintains moist unstable environment over the area through this period...with an axis of max precip water /2.1-2.25/ over the forecast area. This should be supportive of numerous afternoon/evening showers and t-storms each day. Strongest storms...likely associated with sea breeze and outflow collisions...could generate strong wet microbursts. Guidance shows a slight lowering of max temps from mid 90s inland/lwr 90s coast Wed to around 90 inland/upr 80s coast Friday...with slight increase in max temps next weekend. && .AVIATION...Prevailing VFR conditions with temporary restrictions due to afternoon and evening convection possible especially at inland terminals. Lingering debris clouds overnight with a return of showers and tstorms Tue. && .MARINE...High pressure will persist east of the local waters as a surface trough deepens and lingers across the SE Atlantic seaboard states through Friday. This regime will bring a persist southerly flow regime with nocturnal wind surges near 15 kts at times under SW flow and daytime surges from the SSE along the coast due to the east coast sea breeze. Headlines are not expected at this time. Rip Currents: Low risk of rip currents through Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
