Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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 00:00Z, 4.4 hours before the alert went out and 66 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.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tampa Bay, FL wrote its last area forecast discussion before this tornado warning went out at Jun 6, 8:09 PM EDT, 4 hours 15 minutes earlier.

Area forecast discussion, Jun 6, 8:09 PM EDT, 4 hours 15 minutes before

Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
809 PM EDT Sat Jun 6 2020

.UPDATE...

Numerous vortices spinning up this afternoon across the area along
with very heavy rain in the band moving onshore. Behind the band
there appears to be some subsidence and dry air, although most
recently a few showers have developed. The question is where will
the band sit and where will the drier section set up. The
sustained strong winds over the coastal waters have yet to
develop. There is no reason to adjust the forecast at this time.

&&

.Prev Discussion... /issued 215 PM EDT Sat Jun 6 2020/

DISCUSSION...

In the short term Cristobal will dominate our weather with rain
bands moving onshore at least through Sunday. The flood watch will
remain in effect. There is still the chance of locally heavy rain
if a band trains over a specific area. As the storm moves out the
subtropical ridge will again dominate our weather with east
southeast winds and afternoon and evening showers and
thunderstorms. Late in the week a very weak front stalls over the
Big Bend area and could be the focus for heavy rain.

AVIATION...

Temporarily showers have backed off but there is redevelopment in
the Gulf. For now I have kept a tempo for showers in northern
airports VC in the south. Expect some amendments as showers move
onshore.

MARINE...

SCA conditions overnight, SCEC Tampa Bay waters, Charlotte will be
a last minute decision as winds will be borderline. As the week
progresses the subtropical high will dominate our weather with
light southeast winds.

FIRE WEATHER...

No issues.
