"It's not a flowing area of steady rain on the monitor," said Tom Moore, coordinating meteorologist at The Weather Channel, an NBCUniversal company. (NBCUniversal is also the parent of CNBC.) There might be a light drizzle or a steady downpour, depending on how the storm progresses. "What I'm not really sure of, is, will it rain hard enough to cause some kind of weather delay during the game?" he said.
Decisions on whether to delay or call a rainout will be made Thursday night by Major League Baseball officials and the game's umpires. The Yankees have not announced a weather contingency plan.

At current prices, tickets for the game are still substantially higher than for your typical regular-season Yankees game, where the average ticket runs $116 but smart fans can snap up bleacher seats for under $10. It's a veritable bargain for Jeter's last home game, however. "The lowest [get-in] prices have dropped after his announcement was $220," Matcovich said.
Fans holding out on buying to see if either the weather clears or prices drop may not see any better deals. "We're down to just over 1,000 tickets available, and the price hasn't moved much," he said.

If there is a rainout Thursday night, ticket brokers could lose out on some $12.5 million in profits, according to SeatGeek.com. But consumers have some recourse. Most secondary market sites will refund buyers their total cost paid—a relief for those who bought tickets with a significant markup. (Still hunting? Check for that assurance in the fine print before you buy.) Fans who bought directly from the box office can get a refund for the face value, too.
Heading to Boston for Sunday's matchup against the Red Sox isn't much pricier—there, the get-in price is $242. But Yankees manager Joe Girardi has said he would give Jeter the option of resting or playing in that last series, so fans should be aware of that risk when buying. "Wait for confirmation that he's playing," said Matcovich.
