Question

5.Note the temperature and dewpoint in the station model at New Orleans, LA. New Orleans’ temperature at map time was 71 °F and the dewpoint was [(68)(65)(56)] °F. New Orleans was south of the stationary front. [ ]68 [ ]65 [ ]56

6.The temperature at San Antonio, in south-central Texas, was 52 °F with a dewpoint of [(26)(35)(48)] °F. San Antonio was representative of the cold air north of the stationary front. [ ]26 [ ]35 [ ]48

7.Dewpoints, as shown by station models along the Gulf coast south of the stationary front, indicated air with relatively [(high)(low)] concentrations of water vapor. (A guide is that an increase of 18 F° in dewpoint indicates about a doubling of water vapor concentration.) [ ]high [ ]low

8.Winds in the region from Brownsville, Texas to the Florida panhandle, displayed a generally [(northward)(southward)] flow of humid air toward the stationary front. [ ]northward [ ]southward

9.The wind direction at Lake Charles, in southwestern Louisiana, was generally from a [(southerly) (northerly)] direction west of the stationary front. [ ]southerly [ ]northerly

10.The differing wind directions across the region where the stationary front was located suggested that the near-surface airflows were generally [(diverging)(converging)] along the frontal boundary. This aided cloud development and subsequent precipitation, eventually leading to thunderstorms. [ ]diverging [ ]converging
