Not a real problem Rated 5 out of 5 stars
There are slight differences in the reported weather and I 'think' this is mainly because the reports are gathered from data collected at local airports by the weather services. My international airport is about 12 to 15 miles south east of my location and our local airport is about 8 miles south west of my location and that alone with cause variations in the actual local weather where you are.
However my situation is a bit different, I live less than 1-mile from Lake Erie and sometimes I find that the marine forecast can be a bit more accurate because the 'near-shore-marine-forecast' is dependent on what is going on over the open water in the warmer months and ice cover in the colder months. Also lake effect snow falls 15 to 25 miles east of my location, so when the alert starts flashing, it usually is for the whole state and may not effect me directly, but its still good to know and have the alert as a back-up and a general idea as to what the weather is doing.
