Unfortunately, she's really not glowing today with intelligence.

okay, danke :-)

glowing with intelligence, Bill? Do you really say that? Usually, women are said to glow when they're pregnant.

I probably would say something like "unfortunately, she's not her usual intelligent self today." Or maybe, "She's having a blonde moment right now," if the context fits.

Dude - no, not a blonde moment. That's MCP to say the least.

Women glow where men perspire :)

Maybe 'sparkle with intelligence', not glow (in BE, at least).

?

Hier noch ein Vorschlag: I must say she's far from being bright today.

Edit: Oh, ich sehe gerade, das die Anfrage schon ganz alt ist. Na ja, eine zusätzliche Antwort schadet ja nicht...
