716 FXUS62 KJAX 021800 AFDJAX Area Forecast Discussion National Weather Service Jacksonville FL 200 PM EDT Sat Aug 2 2025 ...LOCALIZED FLOODING POSSIBLE FROM JAX NORTHWARD INTO SOUTHEAST GA THIS AFTERNOON AND EVENING... ...WETTER THAN NORMAL PATTERN CONTINUES THROUGH AT LEAST MONDAY... ...New NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE... .NEAR TERM... Issued at 153 PM EDT Sat Aug 2 2025 Showers and storms are beginning to move across the local area early this afternoon, with activity over SE GA moving along the frontal boundary draped over northern SE GA. Satellite derived PWATs still indicate values above 2" across the local area with higher amounts of 2.25" to 2.35" along the frontal boundary over SE GA. Activity will begin to increase in the next hour or so, primarily along the frontal boundary where periods of heavy downpours will bring the threat for localized flooding along urban areas and poor drainage areas for locations generally north of the I-10 corridor and northward across SE GA. These heavy downpours could result in rainfall rates 3"/hr or greater as numerous to widespread showers and storms develop during the afternoon hours and into the early evening hours. WPC has expanded the Slight (level 2 of 4) Risk of flash flooding rainfall southward a bit towards the I-10 corridor over NE FL as well as the Marginal (level 1 of 4) Risk of flash flooding rainfall to include all of NE FL. The frontal boundary will continue to shift southward towards the FL/GA state line through the evening, with showers and storms likely to develop along the I-10 corridor and towards the I-95 corridor. With the cloudier skies over much of the local area and wetter pattern, max Temps will top out in the lower 90s for most locations, with a few locations potentially hitting the mid 90s. Overnight lows will span in the 70s, with lower 70s over SE GA and mid to upper 70s for NE FL and along coastal locations.

(Sunday through Monday night) Issued at 153 PM EDT Sat Aug 2 2025 A stalled frontal boundary will remain draped across the FL/GA state border into early next week continuing the wet and unsettled pattern. Deep tropical airmass situated over the region will support waves of numerous to widespread showers and storms capable of producing heavy downpours. Stronger storms will be mainly focused along the frontal boundary and sea breeze interactions along and north of the I-10 corridor. The main hazards will be localized flash flooding especially where storms train and gusty winds. A north-south temperature gradient will develop with the front dividing the area with highs ranging from the mid 80s along the Altamaha river basin to the mid 90s in north-central FL. Overnight lows will be in the 70s. && .LONG TERM... (Tuesday through next Saturday) Issued at 153 PM EDT Sat Aug 2 2025 A weakening frontal boundary over the FL/GA state border on Tuesday will gradually shift southward through the week. Slightly drier air filters into the area as high pressure builds back into region returning to a more typical diurnal pattern of showers and thunderstorms developing along the sea breezes in the afternoons/evenings. However, saturated soils from the recent multi-day rainfall will make it easier for areas to flood. Temperatures will be around seasonable with highs in the upper 80s to low 90s and overnight lows in the 70s. && .AVIATION... (18Z TAFS) Issued at 153 PM EDT Sat Aug 2 2025 Adjusted timing of TEMPO groups from the previous TAF package as convective activity is already impacting a few of the TAF sites early this afternoon. Most showers and storms will continue through the afternoon hours into the evening hours, with showers expected to linger close to 04Z/05Z. Periods of lower vsbys likely during as convective activity moves over the TAFs this afternoon. && .MARINE... Issued at 153 PM EDT Sat Aug 2 2025 The frontal boundary will move towards southeast Georgia waters later this afternoon, resulting in numerous showers and thunderstorm to develop by this afternoon and continue into the evening hours, with the potential for some embedded strong storms. The frontal boundary will push towards the northeast Florida waters by Sunday and residing through Monday, weakening as high pressure wedges in from the north. High pressure remains wedged to the north as coastal troughing lingers offshore from Tuesday onward, setting up a predominant onshore flow. Rip Currents: Low to moderate rip current risk today with surf/breakers only in the 1-2 ft range. A more solid Moderate risk of rips will develop later on Sunday into Monday as a more onshore wind component pushes surf/breakers into the 2-3 ft range. && .PRELIMINARY POINT TEMPS/POPS...
