Hi Gillis

Please see the WWLN at:

You'll find there a number of plots that show where lightning has 
occured within the past hour or so.  Use this to determine if QRN is 
going to be an issue.

As a very general statement, large T-storms within about 2000-4000km 
most likely will make hearing DX difficult to impossible during mutual 
darkness conditions between you and the QRN source.  However, if you 
time the sunset/rise times over the QRN source and your QTH 'windows' 
can be found in a nights session to make it worth while.

Good luck with your tests!
