Are you dreaming of a White Christmas?

You could be in luck if you live in certain spots of the Bay State.

A few rounds of snow showers in the days leading up to Dec. 25 means there’s a “decent chance” for a White Christmas in parts of Massachusetts, according to the National Weather Service’s Boston office.

The first round of snow is expected to come late Friday night into Saturday from an offshore coastal storm. Meteorologists are forecasting about 1 to 3 inches of snow, with the highest amounts across interior eastern Massachusetts.

“… Not expecting much in the way of impacts from this wintry system, more of a festive pre-Christmas snowfall that will drop anywhere from a coating to an inch or two from Friday into Saturday afternoon,” reads the National Weather Service’s forecast discussion.

Following the snow, get ready to bundle up. It will get downright frigid over the weekend.

“It will be one of the coldest air masses we’ve seen so far in the early portion of these winter months,” Andrew Loconto,a  meteorologist at the National Weather Service’s Boston office, told the Herald.

High temps on Saturday will be around freezing, and then the coldest air will be on Sunday when high temps will be in the low 20s — with wind chills around 10 to 15. The wind chills Sunday night could drop to five below zero.

Temps Monday should rebound into the upper 20s before ticking up for Christmas Eve and Christmas Day.

But as far as precipitation goes for Christmas Eve and Day, there could be rain or snow depending on where you live. It’s looking more likely for rain in southeastern Massachusetts, and snowfall across the interior.

A White Christmas is defined as one inch of snow depth measured on Christmas morning.

“The areas with the best shot for an inch of snow is probably interior New England,” Loconto said. “There’s a decent chance (for a White Christmas) for those interior areas, and for northeastern Massachusetts.”

Mega Millions lottery tickets will more than double in 2025, but the Massachusetts Lottery says you’ll have a better chance of winning.

The Lottery says, “Mega Millions, the multi-state lottery game that has produced a record six jackpot wins exceeding $1 billion, is getting ready for a ‘mega’ overhaul with plans to be bigger and better than ever when the new and improved game launches in April of 2025.”

The Massachusetts Lottery promises “improved odds to win the jackpot, bigger jackpots more frequently, larger starting jackpots, faster-growing jackpots, a built-in multiplier on every play, automatically improving every non-jackpot win by 2X, 3X, 4X, 5X, or 10X – up to $10 million for matching the five white balls, and no breakeven prizes, meaning when a player wins they’ll always win more than the cost of the ticket.”

Five jackpot prizes have been paid out in Massachusetts since the Mega Millions game began in 2022.

Forty-five states and two U.S. territories participate in the Mega Millions game.

The Associated Press quotes Christian Teja, the Massachusetts Lottery Director of Communications, as saying that “They’re constantly looking at ways to enhance the games, maybe make them a little bit different than Powerball.”

“You have probably heard about jackpot fatigue, it used to be $100 million and everybody was playing. Then it became $300 million,” Teja said. “Then it was $500 million. Now, it’s really approaching a billion dollars before you see the sales kick up.”

It currently costs $2 to play Mega Millions but the ticket price will increase to $5 in April 2025. Perhaps the lure of bigger prizes and better chances to win will overshadow the higher ticket cost.
