thankyou for your development work on the SkewT plugin.....I have been waiting a while for this addition to the Windy project.
Could I highlight one fault with your plugin and I believe it has to do with the date time used in the SkewT plot not being the same as the Windy background time display.
1/ In the top image (for time 950hpa wind field at 2200local /12Z), the SkewT wind at 950hpa is ~080/45kts.
2/ When I skipped ahead by three time steps (or advanced ahead by 9 hours - see bottom image for 0700local/ 21Z ), I found that the SkewT diagram was now indicating a 950hpa wind of 080/20kt.
a/ The wind field display at the pointer location within the 21Z frame indicates a strong wind 080/45kt. This displayed an inconsistency with the SkewT 950hpa wind 080/20kt for the same time step.
3/ It appears that the wind speed at 950hpa on the SkewT display for the Windy time step 12Z, coincided with the 950hpa wind field image at the pointer location for Windy 21Z display time.
In other words, the SkewT display/time stamp is 9 hours ahead of the Windy display/time stamp.
I looked closer at this because I found inconsistencies with the T/Td trace compared to the displayed cloud fields.
I tested this with other time steps and areas where winds changed noticeably in speed and direction and found the same inconsistency.
Please take a look at your programming. I hope you can see this and are able to rectify this.......I would love to be able to continuing using this plugin.
