Water leaking under Exterior Sunroom Wall

Hi all, I live in Phoenix, AZ. During this monsoon season we've had some pretty hefty rain storms. The past two days, we have experienced a little water leakage under the exterior wall of our sunroom. It has seaped inside and pooled on the floor, and soaked into the baseboards/wall.
The exterior and interior walls are both of the same material, a wood paneling. There is a pool deck that meets the exterior of the wall, and unfortunately slopes toward the wall. The water only pools against the house near the corner where the brick is and maybe 5 feet to the left.
I know the grading is wrong, but that would be a big expensive project to correct. I have briefly looked into installing some sort of drainage channel along the exterior wall in the ground. I was just looking to see if anyone had some other solution or a quick fix to just get me through the end of monsoon season next month so I can save up some money for a more permanent solution. Thanks!

You might get some responses if you draw the way the water travels on that part of the floor on your pictures. Also, maybe put a leveler there to see how off it is or how many degrees the the floor is and take some pics. I can't see your gutter on the sunroom and I don't see where it shots the water to.
I've seen some products that you can apply over existing concrete (e.g. Top 'N Bond Concrete Patcher being sold by H.D. but no personally tested yet). Since this is not a heavy traffic area that *might* work. I'm interested to hear what the pros here have to say.
Perhaps someone might be able to come up with a McGyver idea to use a rotary tool with a concrete blade to draw a path between the area the water sits and where you want to water to be dumped (a channel).

I would probably suggest you remove the 1x4 trim at the base of the siding...remove the corner post trim if you have to... then make sure the siding is cut at least 1" above the concrete. After you do that, you will have room to caulk the exterior side of the sill plate, sealing it to the concrete. Use the same type of sealant you would use on vertical concrete cracks... in our area Lowe's carries Vulkem, so that might be one suggestion. They also have Loctite S10 polyurethane. Then put the trim back on.
