Powell faces a tricky balancing act as the Fed attempts to bring interest rates toward historical averages.
According to CNBC, the Reserve released new data this week showing the GDP forecast rose to almost 3%, up from the previous predictions of 2.7%.
Policy makers said in a one-page statement that the labor market "has continued to strengthen" and than economic activity "has been rising at a solid rate".
The federal funds target rate, which is now between 1.75 and 2 percent, is the highest it's been in almost a decade, indicating that the nation's central bank has confidence the economy will continue to expand.

With the economy now nine years into an expansion, the move reflects the steadiness of growth, the job market's strength and inflation that's finally nearing the Fed's target level. The Fed's preferred price gauge - the Commerce Department's personal consumption expenditures index - rose 2 per cent from a year earlier in March and April, after spending most of the past six years below it.
Besides raising its projection for rate increases this year from three to four, the Fed removed a key sentence from the previous statement that had been viewed as foreseeing a need to keep rates low for an extended period. With higher interest rates, this means that real interest rates will push higher.
The Federal Reserve is guiding a USA economy that is as close to ideal as it could have dreamed a decade ago, when the darkest days of the recession forced it to take big risks to protect workers, banks and economies around the world from further devastation. Borrowers are likely to see higher bills next month on credit cards and mortgages, especially those with adjustable rates.
Mr Powell called the figures "encouraging" but said the bank wants to see the economy sustain that rate of inflation before it declares victory. Unemployment, now at an 18-year low of 3.8 percent, would drop to 3.6 percent by year's end and to 3.5 percent in 2019 and 2020 - levels not seen in 49 years. Most officials expect the Fed would need to raise rates at least three more times next year and at least once more in 2020, leaving rates in a range between 3.25% and 3.5% by the end of 2020, the same end point officials projected in March. That's weaker than the White House's forecast for 3% growth in 2021, suggesting the Fed is less optimistic about the boost from tax cuts. At this point, there's been little evidence that wage or price inflation is accelerating. That could spark higher inflation. Inflation for the next two years is expected to remain at 2.1%, unchanged from the previous forecast. The stance of monetary policy remains accommodative, thereby supporting strong labour market conditions and a sustained return to 2 per cent inflation. This assessment will take into account a wide range of information, including measures of labour market conditions, indicators of inflation pressures and inflation expectations, and readings on financial and worldwide developments.
