It would be great if we could set up an alert for when forecast lightning flash density or CAPE exceeds a certain value of our choosing at a location.

I’d imagine it wouldn’t take too much time to add this capability since it would just be using the same technique as the existing alerts we already use for other parameters such as wind speed, temperature, etc…. except it would just sample the gridpoint value of forecast lightning flash density or CAPE.

Even better would be if such an alert could be triggered when a combination of both lightning (or CAPE) and 500hpa wind speeds (a proxy for shear) exceeds a certain threshold. This could provide a useful heads up on the potential for severe thunderstorms.

Adding precipitation types such as rain vs snow vs freezing rain (perhaps using colour-coding) to work out where snow would be more likely than rain would be great!

@korina oh and sorry, one more suggestion before I forget. Not sure if this deserves a separate thread but it would also be extremely useful if there was an optional setting where alerts extend out to 7 or 10 days.

I know accuracy is lower at that type of range but if it was available as an option that could be turned on or off by premium or more advanced users (while keeping the default alerts to 5 days unless the user forces a change) and adding a disclaimer that skill will be lower, I think it would be a great addition.

Hello, I'm not sure if this belongs in the Bug reporting topic or on here but ever since about a week or so ago, both the forecast and observed soundings look very compressed vertically compared to what they used to look like, no matter what web browser I use. Has this been intentionally changed recently?

I've attached a couple of before and after screenshots to illustrate my point:

@korina thanks very much Korina :) I'm thinking maybe that could also be extended to cover fog for example, since it's a major issue in aviation without much extra coding work required since it would simply use the existing code for things like rainfall and wind alerts.

Daily max temps below a user-adjustable value would also be useful although perhaps the latter might be more complex considering the different timezones.

@idefix37 thanks very much for that, I've been trying it out and that's awesome! I've just been encountering one problem though - after I load up a skew-T for a location and I step forward or backward in time, the sounding seems to update at erratic time intervals and sometimes even disappears completely at certain forecast time steps. Is this a known issue?

Are there any plans to change the forecast soundings to the internationally recognised skew-T format?

Awesome app by the way. I’ve been using it for a number of years now and the aviation layers are especially useful.

Actually disregard, I just tested it on a few locations within very light precip areas and it looks like the threshold is now around 0.2mm or so. Thanks for getting back to me.

What is the lowest rainfall amount that the maps now show? The lowest value on the scale still shows up as 1.5mm

I think someone else may have mentioned this awhile ago as well but it'd be great if the ECMWF rainfall maps showed precip as low as say 0.2 or 0.1mm so areas of light precipitation don't get missed.

The lowest value currently shown on the scale for ECMWF 3hr precip is 1.5mm while for the rain accumulation, it's 5mm (although I'm not totally sure if lower amounts still show up on the maps?)
