building paver patio in sections?

I just dug out the foundation for a 300 sq ft patio and ready to pour sand and lay the pavers.

I live in an area where it has afternoon t-storms almost every other day (although we had a 3-day stretch of no rain) and I'm afraid to pour the sand since there's no way I can get it done in a day... probably not even in 2 days.

So my question is, is it possible to level the sand and lay the pavers in small sections at a time? I'm sure it would make leveling very difficult but can it be done?
I'm sure I'm not the first patio-installer with weather issues...

Place and compact all of your sand to finished grade. Then just cover everything with a well-secured tarp to keep any rain damage to exposed sand to a minimum. "Only sugar melts in rain", as our high school football coach used to say.

You say you dug out the foundation and are ready to pour sand - you did put in a compacted base material, right?

The slope comes from that, you just use something like 1" pipe so you can screed the sand to a depth of 1".

yeah crushed gravel will be in place tomorrow. I just heard that it's not good to get the sand wet once you even it out... maybe I'm being too cautious?

The sand is just spread and screeded off (uncompacted) and it called a "setting bed". The intent is to use a clean sand and which will be pulled up and the surface sand worked into the tight joints as the surface is run over with a vibratory plate compactor to even out the surface. If some setting bed sand is moved around during a storm, the surface can easily be cleaned up using the edge restraint as vertical guide.

Since the compacted base is usually not disturbed, I have seen 10 or 20 acre installations covered with the 1" setting bed sand and touched up before setting, if necessary. This was for a "high-strength", high-tech" for industrial sites.

Sand should not be the compacted base material. The Interlocking Concrete Paving Institute (ICPI) has a great site for installation "work-arounds" if the proper materials are not available.
