Once again, snow forecasts differ wildly

What’s with the Patch?
By Will Collette

The official forecast from the National Weather Service for Charlestown for today through Monday calls for scattered flurries and no accumulation today, only a 20 to 40% chance of flurries on Saturday with maybe an inch or less of accumulation, and a 50 to 60% of snow on Sunday and Monday.

The Weather Channel’s forecast for Charlestown calls for a 30 to 50% of snow showers on Saturday and, like the Weather Services, less than an inch or maybe nothing. Sunday night, they say we have a 70% chance of getting an inch. On Monday, the odds are higher of precipitation – 80 to 80% and one to three inches of that dreaded “winter mix.”

All of which we should be able to handle. But then there’s the South Kingstown-Narragansett Patch forecast with this headline:

 

It’s OK for a forecaster or two – there now are many different weather forecasting models in play – to be an outlier. Sometimes they’re right.

But so far this winter, the Patch has run a long string of Snowmeggedon headlines like this, only to have the actual results be much less.


In many professions, the secret to success is to “under-promise, then over-achieve.” But the sure way to lose your credibility is to “over-promise and under-achieve.” Ask Brian Williams.

As my colleague Tom Ferrio noted in comments on one of my earlier storm stories, Patch seems to have been doing this sort of exaggerated weather reporting for a while, perhaps to draw more readers to click on the story. Great for short term numbers, but lousy for building trust with your readership.
