Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Tampa Bay, FL (KTBW), launched 12:00Z, 9.8 hours before the alert went out and 174 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Issued at 402 PM EDT Sat Sep 5 2026 - A wet weather pattern will persist through early next week. The main storm hazard will continue to be the potential for locally heavy rainfall that could lead to mostly minor flooding. - Muggy conditions and seasonably hot temperatures in the upper 80s to low 90s will continue, with peak afternoon heat indices in the triple digits, but below Heat Advisory criteria. - There is Moderate risk of rip currents at all area beaches today. Remember, always swim near a lifeguard and never swim alone. && .DISCUSSION... Issued at 402 PM EDT Sat Sep 5 2026 Today-tonight... Upper level high pressure will remain in place as an upper level trough across the eastern US will continue to slowly shift south and eastward through the period. At the surface, high pressure axis will shift southward into central Florida today. Locally, light south/southwest winds will shift onshore along the coast this the afternoon with the formation of the east coast sea breeze and more westward across the interior with the west coast sea breeze. However, the east coast sea breeze is not expected to push as far inland today, given the deep offshore flow. The sea breeze collision is forecast to occur a little closer to the coast than yesterday, generally around the I-95 corridor, later this afternoon/early evening. Much like yesterday, upper level shortwave energy will aid in storm formation. Scattered to numerous showers and storms are forecast to form this afternoon (PoP 50-70%). Isolated to scattered showers and storms are currently moving across the northern CWA from the west coast of Florida this afternoon, with additional isolated showers forming along the sea breeze in southern Treasure Coast. Highest coverage of storms will be along the sea breeze collision, along the I-95 corridor later this afternoon and into early evening. Storm motion will generally be westerly today, which will bring activity back towards the coast and offshore into the Atlantic. Forecast soundings show a very moist profile, with PW values of 2.0-2.3". The environment supports convection, with plenty of instability (MUCAPE of 1800-2300 J/kg), sufficient buoyancy (lifted index of -5 to -8), and sufficient downdraft potential (DCAPE 700-900 J/kg). However, temperatures aloft remain rather warm (-5C to -6C at 500 mb). Because of this, main storm hazards will be frequent lightning, gusty winds up to 45 mph, and torrential downpours. Quick amounts of 2-4" of rainfall in a relatively short period of time in these slow- moving storms will be possible, promoting minor/nuisance flooding in urban and poor drainage areas. The Weather Prediction Center (WPC) maintains a Marginal (level 1 of 4) Risk for excessive rainfall for portions of east central Florida today, mainly from Cape Canaveral to Lake Kissimmee southward. Temperatures will be humid with seasonable to slightly above normal temperatures once again. Afternoon highs will be in the low to mid 90s with peak heat indices of 100-107F. Warm and muggy conditions will continue overnight, with lows in the low to mid 70s. Sunday-Friday... Upper level high pressure across the Great Plains will shift eastward through mid next week as the trough over the eastern US shifts eastward and offshore through early next week. At the surface, and weak frontal boundary will drop into the Deep south and northern Florida by early next week. There is some discrepancy with exactly how far this frontal boundary will make it before it washes out by mid next week. Regardless, this will result in deep moisture shifting over the area into at least Tuesday. Drier air will begin to filter across the area mid-late week. Because of this, higher coverage of showers and storms are forecast early next week, with PoPs forecast to be 30-50% on Sunday, before increasing to 70- 80% Monday, 70% areawide on Tuesday and Wednesday, and 40-70% Thursday and Friday. Storm motion will generally be light and offshore. Storm hazards will be similar to what they are today. WPC has outlooked portions of east central Florida in a Marginal (level 1 of 4) Risk of Excessive Rainfall on Sunday and Monday. Seasonable temperatures and humid conditions are forecast each day, with highs in the upper 80s to low 90s. Warm and muggy conditions will continue overnight, with lows in the low to mid 70s. && .MARINE... Issued at 402 PM EDT Sat Sep 5 2026 Today-Thursday... Generally favorable boating conditions through the period. High pressure will remain in place through the period. Light S/SW winds will become S/SE at 10-12 KT each afternoon as the east coast sea breeze forms. Diurnal offshore-moving showers/storms into early next week. A few strong storms possible with primary impacts of frequent lightning, gusty winds in excessive of 34 KT or greater, and heavy downpours. Coverage of storms will be fairly high into early next week. Seas locally higher in the vicinity of storms. Seas 2-3 ft today will subside to 1-2 ft Saturday through Monday, before building to 2-4 ft on Tuesday, and up to 5 ft in the offshore waters possible by Tuesday night. && .AVIATION... (18Z TAFs) Issued at 146 PM EDT Sat Sep 5 2026 Scattered showers and storms will continue to approach from the west-northwest this afternoon. In addition, the east coast sea breeze has initiated showers along the Martin Coast. Prevailing westerly flow around 6-10 kts has slowed development of the sea breeze along the rest of the east central Florida coast, and the sea breeze will struggle to push far inland this afternoon and evening. VCTS at all terminals this afternoon with TEMPO MVFR/IFR reductions within thunderstorms. Peak convection should clear from north to south late this afternoon and into the evening, lingering across portions of Okeechobee and the Treasure Coast a few hours beyond sunset. Dry conditions are then forecast overnight. Light south winds into late this evening turn west again on Sunday. && .PRELIMINARY POINT TEMPS/POPS...
