Rain is real, not just a shower. We could get well over an inch out of it.
The question is timing. Current models have it sunny through lunchtime on Sat., mid 50's warming to mid 60's, so like the beginning of a nice warm day. Then clouds start rolling in during early afternoon, limiting the continued warming. Rain starts around dinnertime, gets steadier, goes pretty much all night, fading to showers sometime Sunday.
That could be moved up, or back, by 12 hrs or so between now and Sat., and that'd make all the difference for our purposes.
Weather channel plays it safe and tells you everything is coming as early as it COULD come, then will move it back as things become more certain. Accuweather takes a different approach, and throws "showers" over the whole period where it may happen, when the reality is that it will be "steady rain" for only part of that period. I hate that none of them just tell you the truth "here's what we know, here's what we don't".
