Just stopped for lunch in Geneva, Nebraska. Cumulus are now covering the sky although as expected, high based. Cold front is moving in from the north-west, with some kind of pre-frontal wind shift evident too. Latest short-range convection-allowing model guidance still tries to break out thunderstorms close to here by 1800 local time, although it's a little touch a go. With such a stout cap, being close to the front is probably necessary, but the same front will likely undercut cells rather early on in development. However, we'll see - stranger things have happened!
