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)
