Returning summary data SQL

Last Modified: 2012-08-13
My data looks like so -- column 1 is day, column 2 is week of year and column 3 is value

2009-05-05 00:00:00.000            19      8.00
2009-05-06 00:00:00.000            19      16.00
2009-05-07 00:00:00.000             19      24.00
2009-05-08 00:00:00.000             19      32.00
2009-05-09 00:00:00.000              19      32.00
2009-05-10 00:00:00.000             20      32.00
2009-05-11 00:00:00.000            20      40.00
2009-05-12 00:00:00.000             20      48.00
2009-05-13 00:00:00.000             20      56.00
2009-05-14 00:00:00.000             20      68.00
2009-05-15 00:00:00.000              20      64.00
2009-05-16 00:00:00.000              20      64.00

i want to return the following 2 rows

19     32
20    64

where the value returned corresponds to the final day of the week.  MAX(value) wont work because values earlier in the week can be higher than the final day of the week.

Any suggestions?
Watch Question

Try this code.

You should know that 7 will be SAT.  If that's not what you want use the appropriate number representation of the day of the week you want.  Regardless you can use this function to select only the records from the last day of each week.
Select column2, column3
  from table1
 where datepart(weekday, column1) = 7
