  1. AIRMET Zulu ✔
  2. AIRMET Sierra
  3. AIRMET Tango

Why: There are three AIRMETs. Sierra covers IFR conditions and mountain obscuration, Tango covers moderate turbulence, sustained surface winds of 30 knots or more and low-level wind shear, and Zulu covers moderate icing and freezing levels.

Huh, didn't know that: AIRMETs over the lower 48 states are issued every 6 hours, at 0245, 0845, 1445 and 2045 UTC.

The dad joke
AIRMET Zulu warns of icing. AIRMET Tango warns of bumps. My dance moves warn of both.
