For those wondering, here is the LCC for weather for Falcon 9:

- sustained wind at the 162 feet (49 m) level of the launch pad in excess of 30 knots (56 km/h; 35 mph)
- upper-level conditions containing wind shear that could lead to control problems for the launch vehicle.
- launch through a cloud layer greater than 4,500 feet (1,400 m) thick that extends into freezing temperatures
- launch within 19 kilometres (10 nmi) of cumulus clouds with tops that extend into freezing temperatures,
- within 19 kilometres (10 nmi) of the edge of a thunderstorm that is producing lightning within 30 minutes after the last -
- lightning is observed.
- within 19 kilometres (10 nmi) of an attached thunderstorm anvil cloud
- within 9.3 kilometres (5 nmi) of disturbed weather clouds that extend into freezing temperatures
- within 5.6 kilometres (3 nmi) of a thunderstorm debris cloud,
- through cumulus clouds formed as the result of or directly attached to a smoke plume,

The following should delay launch:

- delay launch for 15 minutes if field mill instrument readings within 9.3 kilometres (5 nmi) of the launch pad exceed +/- 1,500 volts per meter, or +/- 1,000 volts per meter
- delay launch for 30 minutes after lightning is observed within 10 nautical miles (19 km; 12 mi) of the launch pad or the flight path

Should be into RP-1 tanking now if not scrubbing. (T-73m)

Prop load at T-70mins... if they're gonna make a go for it.

And that's T-70mins. They need to be starting RP-1 load now if they're gonna try.

Local weather (Thunder Cells to the West and Southwest, moving Northeast) does not look good, 70 minutes before scheduled launch time.

Hearing they are in chilldown for RP-1.

NOTE: You continue pressing ahead until an official scrub is called.

Doppler radar is hinting (to me anyway) that the thunder cells in the area are raining out (dying down)
Let hope this continues... $:-\$
