NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Jul 23, 6:42 PM EST, 48 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 742 PM EDT Tue Jul 23 2024 ...New AVIATION... .SYNOPSIS... Issued at 229 PM EDT Tue Jul 23 2024 Afternoon surface analysis depicts the axis of Atlantic high pressure (1027 millibars) centered to the east of Bermuda that was extending its axis across northeast FL. Meanwhile, a wavy frontal boundary remains stationary across the Mid-Atlantic states, the Tennessee Valley, the Ozarks and eastern Texas. Aloft...deep-layered ridging was building westward towards the southeastern seaboard, while broad troughing was digging southward from the western Great Lakes and Upper Midwest towards the southern Plains states. Latest GOES-East derived Total Precipitable Water imagery indicates that a patch of drier air (likely a decaying Saharan Air Layer, or SAL) extends across locations south of the Interstate 10 corridor, where PWAT values were around 1.7 - 1.8 inches, while a seasonably moist air mass remains in place for locations north of I-10, where values were generally around 2 inches. Scattered convection was developing along a slow moving Gulf coast sea breeze for locations along the FL Big Bend and Nature coasts, with only isolated activity developing along the Atlantic sea breeze boundary along the I-95 corridor in southeast GA. Temperatures at 18Z ranged from the upper 80s to the mid 90s, with dewpoints mostly in the mid 70s, creating heat index values in the 100-105 range at most locations. && .NEAR TERM... Issued at 229 PM EDT Tue Jul 23 2024 The decaying SAL layer that has been limiting convective development thus far today will lift northward later this afternoon towards the I-10 corridor before dissipating this evening. Increasing PWAT values and a prevailing southeasterly wind regime for locations south of I-10 will tend to focus convection for locations along and west of the U.S.-301 corridor during the late afternoon hours, with isolated convection otherwise developing along the inland moving Gulf and Atlantic sea breeze boundaries. Mesoscale boundaries colliding over north central and inland portions of northeast FL late towards sunset will result in pulsing storms, with the decaying SAL layer possibly providing a boost to downdraft potential for storms that will be moving west-northwestward and crossing the U.S.-301 corridor, mainly for inland locations south of I-10. This activity will progress into the Suwannee Valley and possibly the Okefenokee Swamp early this evening, where scattered to numerous storms are expected. Stronger storms in these inland locations will be capable of producing downburst winds of 40-50 mph, frequent lightning strikes, and locally heavy downpours. Convection may linger around the I-75 corridor in the Suwannee Valley and across inland portions of southeast GA through the mid-evening hours before dissipating before midnight. Gradually deepening southeasterly low level flow overnight could bring a few coastal showers into play during the predawn hours, but coverage should be isolated at best. Otherwise, debris cloudiness leftover from inland evening convection will thin out overnight from east to west, with lows ranging from the mid 70s inland to the upper 70s/around 80 at coastal locations, where a light southerly breeze will prevail overnight. && .SHORT TERM... (Wednesday through Thursday night) Issued at 229 PM EDT Tue Jul 23 2024 Stacked ridging starts to get a bit more squeezed Wednesday and into Thursday. A frontal boundary to the northwest makes some progress southeastward into central GA through Wednesday before stalling out, while an upper low east of the Bahamas slowly pivots further northwestward towards the FL peninsula. What this means for us is essentially a slightly stronger daily southeasterly sea breeze, with again the main focus areas being further inland, meeting up with the Gulf sea breeze between about HWY 301 and I-75 where the best chance for stronger storms will be. Temps aloft warm just a bit for this period, which should limit severe potential with just the usual gusty wind/frequent lightning/heavy rain with some stronger storms where the best boundary collisions occur. The aforementioned boundary over GA should increase convective coverage for interior southeast GA compared to Tuesday as well. Similar temperatures in the low to mid 90s will be expected for areas from near I-95 and towards the coast Wednesday and into Thursday. Further inland, the stronger southeasterly flow and increased convective coverage closer to the front will drop temps towards the low 90s with some upper 80s possible north and west of Waycross by Thursday. && .LONG TERM... (Friday through next Tuesday) Issued at 229 PM EDT Tue Jul 23 2024 The work week ends with a pretty similar pattern to Wednesday and Thursday before some changes to the pattern synoptically. An upper trough over the northeast US actually digs pretty far south given the time of year by this weekend and into the start of next week, which drops a new frontal boundary towards potentially as far south as at least southern GA by Sunday before becoming more diffuse. The vicinity of this boundary should certainly keep daily convective chances high for at least the weekend, though some drier air could make it's way far enough south to limit some of this coverage north of about I-10 pending how far south the boundary gets. The general flow direction also gets more uncertain by the weekend and into Monday, depending on the same factors. This period starts generally near climo with respect to temperatures, though trend near to slightly below average by the weekend and into Monday. && .AVIATION... (00Z TAFS) Issued at 742 PM EDT Tue Jul 23 2024 Storms will linger near GNV over the next couple of hours before dissipating. Winds will calm overnight for inland TAF sites. Patchy fog may develop at VQQ in the pre-dawn hours. Light southerly winds around 5 kts develop after 15Z. Winds shift to easterly and increase to 10 kts for the coastal and JAX metro TAF sites after 18Z as the Atlantic sea breeze shifts inland. Scattered showers and storms will form along the sea breezes and be in the vicinity of the TAF sites between 18-23Z. && .MARINE... Issued at 229 PM EDT Tue Jul 23 2024 The axis of Atlantic high pressure will extend its axis westward across the northeast Florida waters through tonight, creating a prevailing south to southeasterly wind flow. Only isolated showers and thunderstorms are possible tonight and Wednesday morning. Seas of 3-5 feet will prevail throughout our local waters from this evening through Thursday night. Otherwise, Atlantic high pressure will lift northward on Wednesday and Thursday, extending its axis across the Georgia waters. This will result in a prevailing southeasterly wind flow throughout our local waters, with scattered showers and thunderstorms possible. A weakening frontal boundary will then sink into the southeastern states late this week, causing Atlantic high pressure to shift its axis south of our local waters, creating a prevailing south- southwesterly flow pattern. Coverage of showers and thunderstorms will gradually increase across our local waters late this week and into the upcoming weekend. Seas of 2-4 feet are forecast throughout our local waters from Friday through the weekend. This frontal boundary will likely cross our local waters on Saturday night and Sunday, with high pressure wedging down the southeastern seaboard resulting in northeasterly winds by late in the weekend. Rip Currents: Prevailing onshore winds will combine with a persistent easterly ocean swell to create a moderate rip current risk at all area beaches this afternoon. Onshore winds will prevail through Thursday, with a slight increase in surf heights that will keep a moderate risk in place at all area beaches through at least Friday. && .PRELIMINARY POINT TEMPS/POPS...
