Developmental Probabilistic Snow Accumulation Forecast (DIA)
National Weather Service Denver/Boulder, Colorado
2108 MDT Wednesday, April 02, 2025

--------------------------------------------------------------------------------
This developmental product contains the probabilities (%) that the given snow
amounts (inches) will occur at Denver International Airport during the respective
3 hour or 12 hour periods.  The probabilities indicate the amount of snow that
is expected to accumulate on runways and other concrete surfaces at DIA.
[T (trace) means more than zero.]
--------------------------------------------------------------------------------

Discussion (03/00-04/00 MDT): Snow will develop in the area by 9-10 am Thursday,
with the main band of snow likely to move across the airport between 11 am and 3
pm, and then off and on showers will linger thereafter through Thursday evening.
There should be a break between midnight Thursday night and early Friday
morning, before the next round of light snow develops Friday mid morning. With
regard to accumulations, snowfall is expected to be light and temperatures
holding just above freezing. Thus, accumulation on Thursday is expected to be
less than an inch on the grass, and little to no impact on runways. At worst
case, there would be a brief period of heavier snow and brief slush on runways,
but that`s only about a 10% chance at this point. Similar chances for
accumulation can be expected Friday, although by Friday evening temperatures
will be turning colder allowing for a little higher chance of snow to accumulate
on runways. But again, those amounts would be light.
