Area Forecast Discussion National Weather Service Jacksonville FL 927 PM EDT Sun Jun 11 2017 ...Locally Heavy Rainfall in Daily Thunderstorm Activity remains the main threat this week... .UPDATE...East coast sea breeze has pushed westward past the western edges of the interior SE Georgia and Northeast Florida. Some locally heavy rain fell across northeast Florida where some pockets of 2-4" rain amount occurred.In the wake of the sea- breeze, stratiform rain continues across most areas of North Floria west of I-95. This stratiform light rain as also persists across interior SE Georgia. Another batch of light rain is pushing up from north central Florida. The areal coverage of precipitation should wane during the late evening hours. Both the HRRR amd NAM show coverage of shower activity increasing toward daybreak over coastal Georgia waters advecting in particular toward the mouth of the Altamaha River Basin with offshore Atlantic activity increasing during the post midnight hours. South of the Georgia waters across the NE Florida waters...short range models show little additional convection overnight except some isolated activity across the offshore Atlantic waters late. For Monday...Model guidance supports repeat performance with greater coverage of afternoon showers/t-storms west of I-95 corridor in onshore flow pattern. Once again...greatest threat will be very heavy downpours and strong wind gusts. Consensus guidance supports high temps in mid to upr 80s. && .AVIATION...Scattered to Broken deck of IFR low clouds expected at times through 02z where there is stratiform rain occuring on axis from Gainesville to Cecil Field. Otherwise, VFR conditions expected for most terminals during the remaining nocturnal hours with mid to high clouds persisting overnight. Saint Simons being the exception during the late night-time hours leading up to daybreak, where Atlantic showers and low clouds may advect into coastal Georgia with some intermittent IFR conditions possible between 10-14z. Deep moisture and light easterly low level flow will tend to focus scattered convection toward the interior by mid to late afternoon on Monday. There will be a short window in the late morning to mid afternoon for coastal terminals to see isolated to perhaps scattered SHRA/TSRA before they transition inland. Some heavy downpours may bring IFR conditions to Cecil and Gainseville in the afternoon as showers push inland. && .MARINE...High pressure ridge remains just north of the region with a weak pressure gradient over the waters. This will support generally light winds and low seas through the upcoming week. Rip Currents: Moderate risk in the onshore flow. && .PRELIMINARY POINT TEMPS/POPS...
