Are the short range precipitation forecasts particularly inaccurate this summer?

[DaveNay]

Is it just me or do the short range precipitation forecasts seem to be more inaccurate this summer? It seems like the 72-120 hour forecasts are very flakey. From one update to another they will cycle from 10% chance of rain to 80% chance of rain. Even the 24-48hr forecasts seem to have a lot more "misses" than in previous summers.

Was there a recent change to the models used for precipitation forecasting that I am noticing behaving different?
