Personally, I'd do my work up in a spreadsheet or on a sheet of paper. If you want them SOMEWHERE in YNAB, you can put things into the scheduler at the bottom of the register with the date that they're due. But know that they'll pop up into the register on that date and if you don't have the money to pay them, you'll need to delete them and change the date of the next iteration that's in the scheduler to reflect the one you haven't paid yet. Or, be pro-active and push the date forward BEFORE they pop up into the register.
I'd make columns with your husband's pay periods and, if you know when you've got some income coming in in the next bit of time (here's where a spreadsheet is better than paper, you can insert columns later) include columns for them too. I'd put up near the top of the column how much you expect to get at that time.
Down the side, I'd put my categories. You can even print your budget from YNAB and write on that. You can print it for some future or past month with no numbers in it, I think. (I'd say to export the budget and use that for this spreadsheet, but I think it might be a little involved...but if you're somewhat proficient on a spreadsheet, that'd be the way I'd go.)
Then I'd figure out how I'll probably slice up the 6/29 check and the next income after that if you can tell when that will be. You know you'll need $121 out of the 6/29 check for the car, then go back down the 4-walls list. Repeat with the next. If things get super tight this is when you see if you want to check into some kind of assistance to get through the next couple months, call some of the bills and see about getting a bit of extra time, or whatever.
YNAB tries to get away from projections, but when things are this tight you need to look ahead and just make sure the basics can be covered AND hopefully use it as a wake up call that there can be NO extras for the time being. AND use it as motivation towards, when the income situation improves (and in your case you know when that'll be) to get things into good shape ASAP.
