is there a general rule of thumb that east coast mtns follow? if there is no snow but cold weather during the week do they make snow daily? or just make it a few times and groom it over and over again.
i was in mt snow yesterday and it was ICY. i dont see snow on the forecast for this week so im curious what next saturday will look like
My understanding is that those mountains that invest in snowmaking will generally blow whenever it is 28 degrees or colder at night...unless there is rain or significant snowfall in the immediate forecast...to build up a base as much as possible an prolong the season into April.
if they have a good snowmaking system and not a lot of snow... they will be blowing snow all night long..... the bump that i call home blows snow from 10 at night to 10 in the morning every day of the week as long as its 2 degrees celcius or less!
Generally they take a look at the forecast. If they are going to have warm days they generally don't blow snow unless a run absolutely needs coverage. Once the decision to make snow is made they generally wait for temps in the 20 degrees range as the warm it is that the poorer quality of snow that is made. See the below links for more details.
Also remember the warmer it is the more the snow will melt. The more it melts, the more ice you are going to have from running over the melting snow. I went night riding up here in the north east last night and the conditions sucked.
