Scientific Project......

I've been a ham for 30+ years and I still don't get all the 'indexs' they they
use if forming a DX Forcast, so, i'm trying something different. I may have
to ask NOAA, NW7US Tomas, or the 4-lander that gives out wx forcast for
help. When I contact a station and talk to them, I'll ask for the temperature
barometric pressure, humidity, & are the wx conditions, rainy, clody clear,
snow, or etc. I'll also note the weather conditions at my QTH.

Eventually, I'll wind up with enought data to put out a report of some kind,
like a scientist fair project.

What say you?

That could be helpful and of merit, if you're talking about VHF-UHF.

On HF, it wouldn't matter at all. All our WX is within the troposphere; our HF propagation is ionospheric. Big difference.

Ain't no "weather" up there.

But you may find if "weather" up there has any effect on "weather" down here.

Ditto what was said about VHF/UHF. If it's HF you use, what's happening BETWEEN you and the other station may be more useful. I can only think of two WX conditions at path end points that affected QSOs, precipitation static and lightning. For the latter I don't stick around chewing the rag long enough to learn about. You really need to know what's going on well above even the highest clouds, which seldom reach 10 miles.

Radio propagation aside, I can recall being amazed how one of my elmers showed me how he could get accurate weather predictions by calling stations to the west of us and getting their current conditions. This was before CNN and The Weather Channel.

I recall when I was heavily involved in 2M SSB/CW, I checked the WX maps daily , looking for fronts and air mass boundaries .
There was ducting of VHF/UHF signals and you could tell where some medium range DX may come from if it was along this path.
As for WX affecting HF propagation,
Some investigation of sporadic E phenomina indicates the high density ionization may occur above the highest clouds in a thunderstorm area.
This is noticed mostly on 6 and 10M so you could call that marginally HF..

A lot of hams have automated weather beacons on APRS. You can see them online, too. This could be helpful for VHF propagation.
