Today is the 20th anniversary of incapacitating snowstorms in Indiana. What are the chances of a white Christmas in Indianapolis in 2024?
What is a white Christmas?
It need not snow Dec. 25 to fit the weather service’s definition of a white Christmas: There just needs to be at least 1 inch of snow on the ground. A trace amount of snow does not count. On average, about 38% of the contiguous 48 states has an inch of snow on the ground on Christmas Day, according to 21 years of data compiled by National Oceanic and Atmospheric Administration.
Will it snow in Central Indiana this Christmas?
On Christmas Eve, there’s a 20% chance of rain after 1 p.m., with patchy fog before noon, according to the National Weather Service. The high is expected to be near 41 degrees. There’s a 50% chance of rain at night, mainly after 1 a.m.
It will be a mild Christmas Day. Expect rain, mainly before 1 p.m. The high will be near 42 degrees. At night there’s a 20% chain of rain before 1 a.m., with the low around 39 degrees.
Indianapolis this year experienced its third warmest fall on record, according to a recent report by NWS. Average temperatures hovered near 60 degrees, roughly four degrees above normal.
Record-breaking pre-Christmas snowstorms’ 20th anniversary
Christmas 2024 will be quite a bit different from Christmas Day twenty years ago when pre-Christmas back-to-back snowstorms dumped a total of more than two feet of snow on central Indiana, shut down highways and resulted in Blackhawk helicopters being resued to find stranded motorists.
According to the National Weather Service, two separate snowstorms started in the Central Plains and eventually hit southern and central Indiana on December 22 and December 23. They brought record or near record snowfall to parts of south central and east central Indiana and significant snowfall to the rest of central Indiana.
Snowfall totals exceeded 20 inches across most of southeastern Indiana with Seymour reporting a two-day record of 29 inches. The area bounded by Vincennes, Terre Haute, Muncie and Kokomo saw a general eight to 12 inches with snowfall amounts diminishing to just a few inches northwest towards Lafayette.
The weather closed Interstates 64, 65 and 74 in various locations across the state, crippled Interstate 70, and caused a train derailment and collision in southern Indiana.
One hundred National Guardsmen were called out in some areas, particularly in those areas where motorists were stranded. Two Blackhawk helicopters and 47 Humvees were used in searching for stranded motorists.
