No major updates needed on the forecast this morning, scattered thunderstorms will be possible this afternoon and evening, mainly along the east coast and over north central Florida.

NEAR TERM

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

The weak low pressure will move offshore by the early daylight hours today. As a result, breezy northeasterly onshore flow will become established, leading to gusts of up to 20 mph possible mainly along coastal locations and the St Johns River basin. The frontal boundary from the past couple of days will start to make its way southward with the departure of the low pressure.
Remaining tropical moisture over the area will allow for some showers and thunderstorms during the afternoon hours along the coast and eastward towards US-301 along north central Florida. With the onshore flow, temperatures along the coast will remain in the upper 80s, while inland areas will temperature highs from the low 90s in SE GA and NE FL, with warmer temperatures likely over far inland NE FL. By the evening hours, lows will dip to the lower 70s and the mid to upper 70s for the coast.

A stalled front over the waters will allow for showers and thunderstorms over the waters through Friday.

SHORT TERM
(Friday through Saturday night)
Issued at 313 AM EDT Thu Jun 13 2024

The surface low that originated over the Gulf of Mexico will be well off the Carolina coast by late Friday with occluded front just south of I-10. Strong surface high pressure centered over the Great Lakes will extend southward into the Mid South and northern Georgia while the upper level ridge builds into the region. This regime will keep a east-northeast flow over the region. The highest moisture content will stay in place south of I-10 allowing for scattered to numerous showers with embedded afternoon thunderstorms Friday. North of I-10 the moisture content is considerably less with precipitable water value's between 1.25 to 1.5 inches while south of I-10 values will be 1.5 to 1.8 inches. Hence the stratification of POPs with highest chances over north central FL at around 60 percent with 30-50 percent POPs across most areas south of I-10. The highest rainfall totals and threat for localized flooding will be over Marion county and southern Flagler counties. Highs Friday will be in the mid 90s inland near 90 at the immediate beaches. Lows during this period are forecast to be in the lower 70s inland, with mid to upper 70s at the coast. Temperatures will briefing heat back up into the mid to upper 90s (near 100 in inland SE GA) on Saturday as the front passes to our south, lowering precipitation chances for Georgia, however scattered thunderstorm potential will remain over NE FL with numerous showers and storms north central Florida.

LONG TERM
(Sunday through Wednesday)
Issued at 313 AM EDT Thu Jun 13 2024

Upper level ridge will remain entrenched over the region on Sunday and Monday. This favors more typical diurnal convection later into the weekend and early next week with an easterly flow on tap. Isolated to widely scattered showers are expected across SE GA and scattered showers and storms over NE FL with storms more widespread across north central Florida.
The easterly flow remains in place Tuesday and Wednesday where similar highest chances of diurnal storms will be over northeast Florida and with isolated to widely scattered showers and storms over southeast Georgia. The rest of the period will have near
