We present a measurement of the cross section for W-boson production in association with jets in pp collisions at {radical}(s)=1.96 TeV. The analysis uses a data sample corresponding to an integrated luminosity of 320 pb{sup -1} collected with the CDF II detector. W bosons are identified in their electron decay channel and jets are reconstructed using a cone algorithm. For each W+{>=}n-jet sample (n=1-4) we measure the differential cross section d{sigma}(pp{yields}W+{>=}n-jet)/dE{sub T}{sup nth-jet}xB(W{yields}e{nu}) with respect to the transverse energy E{sub T} of the nth-highest E{sub T} jet above 20 GeV, and the total cross section {sigma}(pp{yields}W+{>=}n-jet;E{sub T}{sup nth-jet}>25 GeV)xB(W{yields}e{nu}), for a restricted W{yields}e{nu} decay phase space. The cross sections, corrected for all detector effects, can be directly compared to particle level W+jet(s) predictions. We present here comparisons to leading order and next-to-leading order predictions.
