WARSAW, Sept 2 (Reuters) - Central European currencies weakened on Tuesday, shedding some of the gains made a day earlier as markets await the Polish central bank's decision on interest rates and CPI data from the Czech Republic later this week.

"Today should be rather quiet in the region ahead of a busier second half of the week with the National Bank of Poland meeting and inflation prints in Turkey and the Czech Republic," ING analysts wrote in a note to clients.

"CEE FX is supported by a weaker USD and a rebound in global equity markets, which may change quickly due to the local story in the coming days. EUR/PLN, on the other hand, should head back down below 4.250 if the NBP makes a hawkish cut."

The U.S. dollar clawed back some ground in Asian trading on Tuesday following five days of selling, ahead of the return of U.S. traders from the Labour Day holiday.

The zloty EURPLN= lost 0.2% to 4.2645 per euro at 0759 GMT.

The National Bank of Poland is expected to resume lowering interest rates on Wednesday, a majority of respondents in a Reuters poll said, as inflation falls within the bank's target range.

The NBP will cut its key rate by 25 basis points to 4.75%, according to 26 of 30 analysts polled, while four expect it to remain steady at 5%.

Polish inflation eased more than forecast in August, preliminary data showed last month, strengthening expectations for a cut, although these were somewhat offset by projections for a higher than expected budget deficit in 2026.

"This downside surprise solidifies expectations for a rate cut... Given the uncertainty around the NBP's short-term reaction function, the scope for surprises in either direction remains substantial," Goldman Sachs said.

"However, reflecting Poland's weak underlying inflation dynamics and the high level of policy rates, we think the risks are skewed towards a 50 basis points cut rather than unchanged rates."

The Czech crown EURCZK= had inched down 0.1%, trading at 24.4640 per euro

"The EUR/CZK move down seems too fast to us given the move in rates, and although we remain bullish on the CZK due to the end of the Czech National Bank cutting cycle, some correction here would not surprise us," ING said.

Elsewhere, Hungary's forint EURHUF= fell 0.4% to 396.60 to the euro and Romania's leu EURRON= was down 0.2% at 5.0806.

"The forint firmed past 395 to the euro yesterday... it firmed briefly past this support level during yesterday's strengthening but this morning we can see a correction, with an important resistance level at around 396.40 and then at 397.60," brokerage Equilor said.

Stock markets also mostly fell, led by a 1.5% loss in Warsaw .WIG20. The main index of the Budapest bourse .BUX was stable.
