Storm Photography forecast update 9, for May 11
Over the past 48 hours, multiple models have started to indicate - with consistency - a observing-favorable pattern beginning around next weekend, and continuing long-term. What some of the runs have been trending toward is a pattern for multiple-day supercell and tornado events like we haven't seen in many seasons in the Plains: a long-term southwesterly jet aloft with multiple "shortwaves" of energy ejecting (each of which can produce enhanced tornado potential) and with good low-level moisture remaining in place for the duration of the pattern.

Even a muted version of this pattern would likely produce one or two trip-worthy events. For this reason, my confidence in an expedition beginning sometime after Friday is unusually high for a system nearly a week out. Higher probabilities are precluded by the fact that there is still time for a catastrophic reversal in model forecasts. If, however, the models are correct about the long-term nature of this pattern, the result would be a unusually-lengthy expedition akin to the ones I embarked on in 2004 and 2005, with possibly 5 or more big storm photography days in the mix.
To summarize: a severe weather-favorable pattern in the Great Plains looks to get into high gear soon and possibly stay that way for much of the last half of May!
The following table charts the probabilities for a Plains storm photography expedition taking place for the date ranges shown:
