DB Engine :: Partition Function With Where Clause

I am facing issue in generating total sum and daily sum from table ThresholdData.

DailyTransactionAmount should be sum of todays amount in the table
TransactionAmount should be sum of all amount in the table.

Basically,

1. I don't want to scan ThresholdData table twice.
2. I don't want to create temporary table/table variable/CTE for this.
3. Is there is any way to make it done in single query.

I hope, where criteria is not possible in partition function. I am trying query something as given below,

SELECT  TransactionDate,
  TransactionAmount,
  ROW_NUMBER() over (order by TransactionDate) AS TransactionCount,
  SUM(TransactionAmount) over (partition by id ) AS TransactionAmount, 
  SUM(TransactionAmount) over (partition by id ,CONVERT (DATE, @TodaysTransactionDate)) AS DailyTransactionAmount
 FROM ThresholdData
 WHERE id = @id
 AND transactiondate >= dateadd(d,-@TransactionDaysLimit,@TodaysTransactionDate)
