Today's verdict

Thunderstorms in the forecast — lightning and cyclists are a bad combination.

Thunderstorms — lightning and cyclists do not mix — get off the road before they arrive.
Pavement: wet — wet during the likely ride window — reduced braking, road spray, limited visibility to drivers.
NWS alert active — check the alert before rolling out.
25 mph wind — strong — plan for slow outbound if wind is against you.
Exposed + wet + windy — on road traffic in wet windy conditions — visibility and handling margin drop together.
