Comparing Forecasts: Snow Predictions Differ for Friday in Paramus
The weather can be unpredictable. Even some of the most well-trusted meteorologists can get it wrong sometimes, but it is interesting to observe how different forecasts are to each other. Many people rely on the weather app on their iPhone, but their predictions can be widely different than that of other weather forecasts.
Let’s compare the forecasts of Friday’s snowy day in Paramus between the iPhone weather app in the latest iOS version to the National Weather Service.
Examining the iPhone Weather App: How Does it Get its Data?
As of 1 p.m. on Friday, the National Weather Service predicted Paramus to have an accumulation of snow “mainly before 5 p.m.” with a 50% chance of snow in the evening, mainly before 8 p.m. The iPhone weather app gives a more descriptive look at the weather. At 1 p.m., they said there was a 90% chance of snow within the next hour, but starting at 3 p.m. Apple only showed clouds in their future forecasts for later that day. From 3 p.m. until later in the evening, Apple showed no percentage of snow for any of the hourly forecasts. The National Weather Service and the iPhone weather app shared some similarities with their prediction of wind gusts estimations being in the same range and temperatures also being nearly identical. While one weather forecasts predicted snow throughout the day, the other had snow stopping in the early afternoon and not continuing. Let’s take a closer look at why these predictions were so different in the same area.
Accuracy Comparison: Which Forecaster is More Reliable?
Apple gets its weather data from a variety of sources. Its temperature and precipitation forecasts are provided by the Weather Channel. Apple’s air quality map comes from data through BreezoMeter and QWeather. The National Weather Service has their own data from satellites, doppler radars, computer models and high-speed communication systems. Forecast Advisor, which tracks the accuracy of weather forecasts, shows that for the Hackensack area code it was The Weather Channel, which provides weather to Apple, that had the most accurate forecasts in December at about an 89% accuracy rate. Meanwhile, the National Weather Service Digital Forecast and AccuWeather had about an 80% accuracy rate in the month of December for Hackensack.
Understanding Forecasting Challenges: Why are Predictions Inaccurate?
The National Weather Service explains the challenges with trying to predict the weather saying that the amount of research and data that goes into forecasting makes for a complicated process. NWS Forecaster Mark Bloomer explains that they deal with many forecast models that run several times a day and they must decide which ones are the most reliable through “how well they seem to be handling current weather, how realistic their output is, and how consistent the forecast models are being from one run to the next.” Meteorologists are never going to be 100% accurate whether it is through your phone app or through NWS. So check the forecast, but be prepared for anything.
Weather Forecasts: Be Prepared for Anything, Even with the Best Technology
The weather can often surprise us, and even the most advanced technology and accurate forecasting models can still lead to inaccurate predictions. Whether you rely on the iPhone weather app or trust the National Weather Service, it is important to remember that no forecast is foolproof. While it’s always beneficial to stay informed about the weather conditions, it is equally important to be prepared for unexpected changes. Carry an umbrella, keep warm clothing handy, and remain cautious when venturing out in uncertain weather conditions. Despite advancements in technology, weather forecasts are still subject to the inherent challenges and complexities of predicting nature’s whims. So, while we can certainly rely on weather apps and services to provide us with valuable information, it’s wise to temper our expectations and be prepared for anything.
