SIOUX CITY, Iowa (KTIV) -

You might have seen snow this time of the year, but have you ever seen it pile up like it did today?

It's been decades since Mother Nature has delivered us any accumulating snow during the month of May.

Many of us have probably seen snow flakes fall in May, but accumulate?

Now, that's a different story.

The last time that happened, on May 28th, 1947, when Sioux City received 0.8" of snow.

The reason for the 66 year gap, warm ground.

"It's not unusual to get spring snowstorms, but with warm soil temperatures, it's really tough for it to accumulate," Brad Adams, Hydro-Meteorological Technician.

High temperatures in the 70s and 80s the past several days, along with above freezing temperatures at night, also meant that Wednesday's snow battled some warm ground.

So how did any of it pile up?

Sometimes the snow is falling so quickly, that despite warm ground, it still manages to accumulate.

High precipitation rates can also drop air temperatures.

In fact, from 6 a.m. to 7 a.m. Wednesday, temperatures dropped 7 degrees at Sioux Gateway Airport from 43 to 36 degrees, as rain changed to snow on Sioux City's northside.

But no matter how you slice this latest snowfall, one thing is for sure, a strong May sun along with warmer temperatures, means the snow will soon only be a memory.

But one that will still stick in the minds of many for years to come.
