I bought the HD Weather Station on Jan 16th 2017 and now its been roughly 2 months since I've owned it. Despite it running through the calibration phase, I've noticed that the forecast is almost always wrong. I understand how it works as I'm a meteorologist, it goes off pressure tendencies and lately here in Amarillo,TX...all the storms are missing us. So while we may go through an insane pressure drop due to a nearby low pressure system developing we get winds not rain. The few times we've gotten snow it says clear and never said snow prior to the day...seems pretty inaccurate to be honest, contemplating asking for a refund.
