Yeah I see chances of rain on Saturday. I look at weather computer models all the time and each model has the front diving into our area. Us meteorology majors and our professors are trying to figure out the timing but most models are pushing the storms in around game time and maybe a little earlier. The rain saturated ground could be very conducive to flooding again as it did in 21 Apartment complex in my parking lot, the creek behind my building, and one of the buildings did actually get water in the 1st floor. Luckily I'm on the 4th floor. Here is a link to some precipitation data. BTW the day it flooded this past Friday we got 3.5 inches of rain WOW.

Let me get a few models and show you guys a little of what we do..There are chances for some isolated strong to severe storms but its still a little to far out to say for sure. Anyway here are a few..You scroll over the times. By the way Z time, you subtract five hours from what it says. 0Z=midnight in England which is what Z time is based on so all forecasts come out at the same Z time. 0Z is midnight then it goes like a 24 hr clock up until at midnight it changes to 0. So the time of a forecast for 9/26 Saturday at 0Z would actually be for 7PM on Friday night. When the time changes in November, we'll be 6 hours behind Greenwich, England, not 5 so you would subtract 6 then and 0Z would be 6PM, not 7PM but don't worry about that.
GFS:
http://www.txtornado.net/GFS/wna_slp_gfs_12z.htm (look at 60-84hrs out so the forecast is from 0Z Saturday-0Z Sunday [7PM Friday to 7PM Saturday]). You can see rain beginning Friday night and lingering into Saturday with coverage and intensity increasing as the heat of the day on Saturday fuels the storms.
NAM:
http://www.txtornado.net/NAM/wna_slp_nam_12z.htm (60-84 hrs out). This shows much lighter rainfall and less coverage Friday. This is probably more of scattered showers and not as much heavy rain than the GFS.
CMC (Canadian Weather Model):
http://www.txtornado.net/gem/gem_12z.htm (60-84hrs out). This shows a line of storms moving into our area on Friday night into Saturday with the storms increasing in intensity. The precip map is at the bottom right hand corner of the screen. Watch it while you move your mouse over the times. Also don't think this is what the rain will look like for sure. These are computer models and are fairly accurate, but individual storms (convective storms) it sucks at.
What I can see is that the CMC and GFS are pushing the storms through slower than the NAM and have higher intensity rainfall. I'll have to watch how much moisture is being brought in closer to time and what the wind shear (changing wind with height) and instability (how unstable the atmosphere is) before I can forecast intensity like amount of rain and severe storm possibilities.
Here is a satellite imagery where you can see this huge upper level low pressure over the Plains that will connect back with the jet stream in a day or two and help to provide favorable environment for storms to develop and push the storms into our area.
