Display screen with transitional graphical user interface

FIG. 1 is a front view of a first image in a sequence for a display screen with transitional graphical user interface, according to the new design; and,

FIG. 2 is a second image thereof.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-2 . The process or period in which one image transitions to another image forms no part of the claimed design.

The portions of the graphical user interface that are shaded depict a contrasting appearance. The longer outermost broken lines showing an electronic device illustrate environmental subject matter. The broken line rectangle showing a display screen and all other broken lines showing elements of the graphical user interface illustrate portions of the article. The broken lines form no part of the claimed design. The narrow double lines, including a broken line segment at the left end of the lower line, form part of the claimed design.
