Thunderstorm Outlook: Weekend 3 - 4 September

An unstable airmass will be present over southern Germany, northern Italy, and also the area of southwestern France/northern Spain. However, for Saturday night, models forecast only precipitation at the south side of the Alps, so that those will likely be tonight's only sustained storms... which has come to be typical this summer. For Sunday night a cold front will affect western France, and thunderstorms should result because of that, but models are late with generating precipitation - destabilization might not be enough for storms to develop before midnight.
