Images are in the following order from left to right: 
250 hPa geopotential height (dam, contours) and wind (m s[SUP]-1[/SUP], shaded) 
500 hPa geopotential height (dam, contours) and absolute vorticity (10[SUP]-5[/SUP] s[SUP]-1[/SUP], shaded) 
850 hPa geopotential height (dam, contours) and wind (m s[SUP]-1[/SUP], shaded) 
MSLP (hPa, solid contours), 1000-500 hPa thickness (m, dashed contours), and PWAT (mm, shaded)
