Great idea!
I'd love to have it into the Windy platform
instead of running the plugin any time I need it.

@LucianoGIS @TomSlavkovsky
Luciano, it'd be great if you could contribute in Blitzortung project to cover your area.

Think about it!

@rittels
You are awesome! thx

@WXcycles
... also by using "airgram"

@rittels
Thanks a lot.
I think that trajectory tool is also usefull for very short range forecast (up to 2 hrs)
for thunderstorm movement (by experience I use 700 hPa winds).

..... For an airport you can have the declination following steps 1,2,3,4

@MacRob-0

As magnetic declination varies a lot across a map,
the compass indication (you ask for) would be right for place A but wrong for place B......

Very interesting! Thank you!

How can I see the duration and the "start" button?
I think the dark grey window (at lower left) must relocated a little higher.

@Pro-Meteo-User
As I know, COBEL is a 1-D model and must be coupled with a 3-D model (GFS, ECMWF etc)
to simulate the 2m air temperature and relative humidity
over a specific area (e.g. airport) .
It is a usefull tool for fog forecasting (localy), but it is not a global model.

Also you can use this method https://community.windy.com/topic/8455/fog-and-forecasted-fog/3

Long ago I've notified you about wwlln.net
here:
https://community.windy.com/topic/8066/please-put-lighting-spots-on-the-map/13

As I read in http://wwlln.net/new/map/
"WWLLN has a 30-minute delay in the data" and
"presently they have only 40 sensors, worldwide".

You say they provide near real time data (every 1 minute). Is it for free?

@jmh2002
It also happens if receiver's noise exceeding the noise threshold.
Other "strange" images are:
Spirals, due to receiving another radar's transmitted pulse.
Radial spokes, due to WiFi 802.11N base units operating within wx. radar spectrum space (5600-5650 MHZ).

@vicb

250 hPa data are not a simple interpolation.

@jamalas1
IMHO: many years ago, when wx. models provided output only for rain,
it was usefull to have LI, K-index etc, to forecast tstms (or showers).

Now, wx. models (e.g. ECMWF) provide thunderstorm forecasts (light-moderate-heavy), can separate rain-snow-tstms and even provide lightning (density) forecasts.
Those forecasts are considering a lot of parameters (including instability).
I don't think that by consulting one parameter (LI index), I can forecast tstms in a better way than the model which takes into account a lot of parameters.

Personally talking, convective available potential energy (CAPE), already provided by windy, is a better measurement of instability.

@RikusIAANZ
467 kts ??? No way!

@vicb
Thank you very much!
I want to mention that data for 250 hPa (34000 ft) are not included.
Temp. @ d.p. line goes straight from 300 to 200 hPa (30 to 39 kft).
