UPDATE: Grand slam homer under a rainbow. Maybe it's a good night after all. Woo Hoo! 

Earlier: Not a great night to be at the ballpark. Baltimore remains under a flash flood watch, with a cold front marching through and wringing a lot of this moisture out of the atmosphere.

Here's the bad news:

"SHOWERS AND THUNDERSTORMS WILL CONTINUE UNTIL EARLY THIS EVENING.
THUNDERSTORMS WILL BE CAPABLE OF PRODUCING VERY HEAVY RAINFALL
WHICH COULD CAUSE FLASH FLOODING. THE MOST SUSCEPTIBLE AREA FOR
FLASH FLOODING WILL BE ACROSS THE WASHINGTON-BALTIMORE METRO
CORRIDOR WHERE A FLASH FLOOD WATCH IS IN EFFECT UNTIL 8 PM.

"IN ADDITION...SOME THUNDERSTORMS ACROSS THE OUTLOOK AREA MAY BE
SEVERE...PRODUCING DAMAGING WIND GUSTS AND LARGE HAIL."

The radar loop shows the bad stuff beginning to clear the area, slowly.

The good news is the front should move through, and begin to clear the skies and dry the air after 8 p.m. The temperature, which never got much above 70 degrees today, will turn toward a damp, chilly low of 64 degrees, with northwest winds 6 to 9 mph. 

Let's hope the game gets the green light and the O's heat things up.

UPDATE: But you already know this. Clouds are thinning and the game is underway.
