Days out: the forecast we are already watching
Once a pour date is on the calendar, we are checking the forecast for it the same way you probably are. Rain and cold are the two things that actually change the plan. A wet forecast for pour day itself is the clearest signal, and a hard freeze overnight right after a pour is the other one, because a slab that freezes before it sets is a slab that gets poured twice.
This is also the stretch where we compare notes with the ready mix plant, since a forecast that moves your date usually moves several dates on the schedule at once. That is part of why an early heads up on a marginal forecast helps everybody land on a real date instead of guessing.
The morning of: what we are actually looking at
The morning-of check is where a marginal forecast gets settled. Radar timing matters more than the percentage chance of rain, because a pour that finishes an hour ahead of a system is a different day than one that starts as the rain arrives. Overnight lows for the next day or two matter as much as the daytime number, since a slab does most of its early curing after the crew has already gone home.
A forecast that looked fine three days out can shift overnight, so the morning-of read is not just a formality. It is the last honest look before a truck gets ordered, and it is the one that actually decides whether the day goes ahead.
- Rain timed to arrive before finishing is done
- An overnight low that drops the fresh slab toward freezing
- A sharp, fast-moving system that changes the radar picture within hours of the call
What does not cancel a pour
A cold morning that warms up through the day, a light shower well before or after the pour window, or a breezy, sunny day are not cancellation weather. Those change how the crew runs the day, starting earlier in the heat, moving faster on a dry, windy afternoon, working the mix and the timing for a cold snap, but they do not move the date on their own.
If your date moves
We call you. The pump moves with us because it sits on our own trailer, so a reschedule is not waiting on somebody else's equipment or somebody else's calendar the way it might be for a crew that has to borrow one. Loads get booked ahead and the good pouring days fill fast, so the sooner a date needs to move, the sooner we can find you the next one.
What it costs you when weather moves the date
Nothing changes on the number you already approved. A weather delay is not a change in scope, so it does not touch your written estimate. You are simply on a different day for the same job at the same price.
