Use the LEFT/RIGHT arrows on your keyboard to navigate between different forecast times (and verification)
Use the UP/DOWN arrows on your keyboard to navigate between:
(1) 300-hPa geopotential heights (dam; solid contours) / temperature (c; dashed red), isotachs (m/s; shaded according to scale), and wind barbs (standard convection)
(2) 500-hPa geopotential height (dam; solid contours), absolute relative vorticity (10-5 s-1, cyclonic only shaded according to scale), and wind barbs (standard convention)
(3)1000-500-hPa thickness (dam; dashed contours with 540 separating red/blue ), precipitable water (mm; shaded according to scale), and mean sea level pressure (hPa; solid contours)
