This is my first post here, so please go easy on me.
Just a bit of background. I have 2 degrees in meteorology, although I never went into the field. However my interest in the field has always remained high and I’ve always had well-respected weather stations at home.
This is my first experience with the WeatherFlow weather station and I certainly liked the concept. I was aware of some of the issues that were being worked on, but I don’t know what the current state of development of these issues are.
It’s only been a bit less than 24 hours since I installed the Air & Sky units, but we’ve had a decent sampling of weather already. I’ve been very impressed with the unit, I really have. I was not expecting the barometric pressure to calibrate as quickly as it did. My temperature, humidity/DP, barometric pressure and rain totals all seem to be spot on. I was surprised at how accurate the rain totals were as I thought that was initially an issue. if it was, it seems to have been solved.
On the wind side it’s a mixed bag. Prior to the onset of a storm we’re currently experiencing here in N.Y., my winds seemed to be very accurate and comparable to my Davis VP2, but a bit higher, which is good as I’ve always felt the VP2 was reading somewhat low. Additionally, the VP2 often misses gusts that occur outside of the reporting period. As an example, my Sky reported a gust to 30mph and my Davis totally missed it. I confirmed conditions at that time by looking at both the neighboring PWS (which obviously vary hugely in accuracy) and the more trusted NWS/FAA locations. The latter reported similar gusts at about the same time. Kudos to WeatherFlow!
However my wind went downhill once we had a period of moderate to heavy rain. Rain intensity has lessened as I post this info. My unit was reporting frequent gusts of 25 to 35mph when, in actuality, the winds may have been 5mph. I confirmed this by observation (branches on trees hardly moving in all areas and finally, stepping out on to my deck where there was almost no wind at all yet a gust was recorded of 25mph. So the combination of wind & rain is obviously causing an issue. I also confirmed this with neighboring stations, both PWS and NWS.
I seem to recall having read that WeatherFlow was working on a fix for this, but I’m not sure what the current status of this is.
The other interesting thing, and contrary to what I thought others were reporting, is lighting detection. In my case we actually had one of those relatively rare winter thunderstorms. Lightning strikes were reported about 5 miles away and thunder was clearly heard at my site. Yet there was no recording of lightning on my unit. I thought others had lightning detection when there was none, yet here I had none when there was.
Finally the last of my 3 issues is a more minor one, involving graphing. For some reason the graphing of rain rates seems very off. Looking at the actual data from my unit, I show a rain rate of .08"/hr (which is correct), but the graphing of that data shows a virtually constant .55"/hour for over 2 hours. That’s not even close to what’s happening over the past 2 hours where the rain has lessened in intensity. So it seems to be a bug in the graphing software (unless I’m not interpreting this graph properly) since the actual data page seems correct.
Other than those 2 points, I’ve been very impressed with the unit as well as the great staff here! Any information on these issues would be greatly appreciated and I hope I’m posting in the correct area.
