The episode as NWS JAX wrote it up.
Deep tropical moisture was in place (PWAT 2.5) with the area on the east side of TS |Cristobal as the storm approached the LA Gulf Coast. Waves of moderate to heavy rainfall with isolated embedded thunderstorms pivoted northward across the local forecast area into the evening with a more solid band of moderate to heavy rainfall developing across north Florida as low level convergence increased between a lifting frontal zones across south-central FL and a persistent low level ridge axis holding firm just north of the Altamaha River basin. This ridge will limit the northward extend/expansion of the convective band into Sun, and generally focused a W-E oriented swath of heavy rainfall generally near and south of the I-10 corridor overnight into Sunday morning on 6/7. The ridge strengthened north of the Altamaha Region Sun afternoon 6/7, which shunt the corridor of heavy rain SSW toward the I-75 corridor of NE FL with drier mid level air (700-500 mb) decreasing rain chances across SE GA and eastern NE FL into Sun evening. In addition to heavy rainfall potential, there was a low tornado threat for NE FL into the evening of 6/6 with elevated 0-1 km shear values 20-25 kts with low level ESE winds under increasing SSW winds out of the GOMEX, with speeds increasing to 35-45 kts at 850 mb through 06z Sun 6/7.
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 Jun 5, 7:46 PM EST, 3 hours 14 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 846 PM EDT Fri Jun 5 2020 .UPDATE... Warm, humid conditions continue this evening with 8 PM temperatures across the area still in the low 80s to upper 70s and dewpoint temperatures in the 70s. Light rain will remain possible overnight, mostly across north-central Florida. No major changes wit this forecast update. && .PREV DISCUSSION [728 PM EDT]... .NEAR TERM [Through Saturday]... The cirrostratus shield will continue to advance northward and will blanket all of inland southeast Georgia late this afternoon, which may put a lid on convective coverage where hotter temperatures were experienced today, although some isolated convection may be possible early this evening along the Altamaha River as outflow boundaries from convection over central Georgia press southward into a moderately unstable air mass. Otherwise, the shield of heavy showers associated with a deep surge of tropical moisture associated with Tropical Storm Cristobal will cross I-4 before sunset, with short-term, high resolution guidance indicating that this shield will erode after sunset as mostly stratiform rainfall reaches north central Florida. A lull in rainfall is likely overnight, followed by another round of stratiform rainfall overspreading the Nature Coast and Florida Big Bend region during the predawn hours as Cristobal begins to strengthen over the southern Gulf of Mexico. This rainfall should reach into north central Florida and southern portions of the Suwannee Valley by sunrise. Otherwise, cirrostratus will continue to thicken over the rest of our region, keeping lows mostly in the lower 70s. Troughing aloft over the Tennessee and lower Mississippi Valleys and stout ridging building over the eastern Bahamas and Cuba will keep deep southwesterly flow in place over Cristobal and over our region this weekend, which will focus several convective bands over the eastern Gulf of Mexico and the Florida peninsula through Sunday morning. Guidance indicates that a particularly heavy outer band will rotate north-northeastward from the Florida peninsula on Saturday afternoon, with heavy downpours progressing into north central Florida by early afternoon and then the rest of northeast Florida by the mid to late afternoon hours. PWATS will rise to the 2.2-2.4 inch range by sunset, increasing the potential for heavy rainfall amounts during a relatively short period of time within this initial outer rain band that will move through our region. Overall soil moisture levels remain too low for a Flood Watch in north central Florida and the Suwannee Valley at this time, but localized flooding will be possible in these locations, particularly in urban and low lying areas, given warm temperatures aloft and the deep tropical air mass that will be in place. Highs on Saturday will again be warmer in southeast Georgia, where mid 80s will prevail, while afternoon rainfall keeps highs closer to 80 in north central Florida. .SHORT TERM [Saturday Night through Monday Night]... Tropical Storm Cristobal will continue moving northward through the central and then the northern Gulf of Mexico on Saturday night and Sunday. Global models indicate that significantly drier air currently positioned west and northwest of Cristobal will wrap around the tropical cyclone's circulation by early Sunday, which should begin to shutoff convective potential over our region towards noon on Sunday. Bands of heavy showers and a few embedded thunderstorms will continue to stream northward through our area on Saturday night, with some model guidance even depicting locally heavy rainfall shifting over southeast Georgia overnight, providing more beneficial rainfall for those locations through Sunday morning. Heavy rainfall and localized flooding will continue to be our main hazards locally, with a few training bands of convection possible in the Suwannee Valley and north central Florida, where higher rainfall amounts of 3-4" will occur on a widespread basis this weekend, with locally higher totals possible. Rainfall amounts elsewhere in northeast Florida of 1-3" are forecast this weekend, while later arrival of downpours keeping totals in southeast Georgia mostly below 1 inch. The dry slot advecting into our region on Sunday afternoon should result in breaks in the thick cloud canopy, allowing highs to climb to the mid and possibly upper 80s inland, while breezy southeasterly winds keep coastal highs mostly in the lower 80s. Convective coverage may increase somewhat by late Sunday afternoon and early evening along inland moving sea breeze boundaries as instability increases, with most of Cristobal's outer bands shifting west of our region as the cyclone reaches the Louisiana coast. Deep-layered ridging will continue to shift westward and directly over our region by Monday afternoon, with morning subsidence allowing for more insolation that should drive highs back into the lower 90s inland, with active afternoon sea breezes keeping coastal highs in the mid 80s. Scattered to numerous thunderstorms should congregate along U.S. Highway 301 by late afternoon Monday as the Gulf and Atlantic sea breezes collide, with a few storms pulsing to strong levels as greater instability develops locally, with downburst winds and heavy rainfall being the primary hazards. Convection should remain mostly diurnal in nature early next week, and a tropical air mass will result in lows around 70 degrees. .LONG TERM [Tuesday Through Thursday Night]... Deep-layered ridging in place locally on Tuesday will begin to break down by midweek as ridging aloft builds over Texas and forces Cristobal's remnant tail of deep moisture slowly eastward across the Florida panhandle. Relatively light flow throughout the atmospheric column on Tuesday should allow for widespread diurnal convection to erupt along inland moving sea breeze boundaries. Stronger surface ridging should then build north of our region towards midweek, possibly advecting a drier and more subsident air mass into our area from the Atlantic waters by midweek, trapping Cristobal's remnant moisture just west of our area. This moisture may then reach our region late in the week. Higher convective coverage on Tuesday may keep highs in the upper 80s to near 90 inland, and then deeper easterly low level flow should keep highs mostly in the mid to upper 80s for most locations on Wednesday and Thursday. Lows may fall into the mid to upper 60s at inland locations by midweek as a drier and more subsident air mass potentially moves overhead, with onshore flow keeping coastal lows in the lower 70s. .AVIATION... [Through 00Z Sunday] Patches of light rain this evening, mostly across north-central FL and the NE FL coastline. Increasing chances of showers after 06z near GNV, after 16Z everywhere else. Winds mostly from the southwest this evening, becoming light and variable in the next couple of hours. Winds will pick back up late Sat morning/early Sat afternoon, becoming southerly at 5-10 kt, with southeast winds at GNV. .MARINE... Tropical Storm Cristobal will emerge over the southern Gulf of Mexico early this evening and will be steered northward towards the central Gulf coast region this weekend by Atlantic ridging that will be centered just east of the Bahamas. Prevailing south- southwesterly winds tonight will shift to south-southeasterly by Saturday afternoon, with Caution speeds of 15-20 knots expected throughout our local waters through Saturday evening. Seas should build to 3-5 feet offshore by Sunday, with 2-4 foot seas expected this weekend near shore. Winds and seas will then diminish early next week as Cristobal's remnants move into the lower Mississippi Valley. .FIRE WEATHER... Southwesterly surface and transport winds this afternoon and evening will shift to southerly overnight. Heavy showers and embedded thunderstorms will then overspread north central Florida by the early afternoon hours on Saturday and will reach the rest of northeast Florida by the late afternoon and early evening hours. Surface and transport winds will shift to east- southeasterly in northeast and north central Florida, with cloudiness and widespread rainfall resulting in low daytime dispersion values. Showers and thunderstorms will increase in coverage across southeast Georgia from Saturday evening through Sunday morning. Surface and transport winds will remain southerly on Saturday and Saturday night in southeast Georgia. Higher rainfall coverage will then shift to the Suwannee Valley and inland portions of southeast Georgia by Sunday afternoon, with low daytime dispersion values expected for most locations. .HYDROLOGY... Heaviest rainfall amounts this weekend are forecast to occur in north central Florida and the Suwannee Valley, where widespread 3-4 inch totals are expected, with locally higher totals possible. Widespread 1-3 inch totals are forecast elsewhere across northeast Florida, with totals likely an inch or less throughout most of southeast Georgia. Given antecedent dry soil moisture, our main concerns for localized flooding this weekend will be in urban and low-lying locations, but locations in the Suwannee Valley and north central Florida will be closely monitored on Saturday night and Sunday for training bands of convection on the far eastern periphery of Cristobal's circulation. && .PRELIMINARY POINT TEMPS/POPS...
