It's that time of year when over-excited meteorologist wannabees start posting to social media computer model output showing ridiculous snow totals. Experienced meteorologists know better than to treat a single these single panels of QPF (quantitative precipitation forecast) as a legitimate forecast, particularly when the model output is for many days into the future.
Copying and pasting a panel from the 10-day GFS or European Model is not the same as considering the actual meteorology of the situation and making a reasonable forecast.
However, social media is already filling up with "potential" snowstorms that look official but are not.
There is always uncertainty with weather forecasting. When these unfortunate posts are readily spread around social media by your friends and presented as "another opinion," the confusion surrounding winter forecasting is multiplied. It is best to stick to legitimate weather sources and tune out the debris flying around the web.
