Yeah but the convection is well south and east of the center.

Take another look at that image - it was taken yesterday afternoon at 5:27pm CST (2327Z). Look at the purple time stamp near the bottom right of the image. So while the web page was recently updted, the image is 12 hours old.

There does appear to be a little convection developing south of the center now.

What I find interesting about the quikscat is the fact there are TS force winds to the N of the center where there is no convection of note. Sat views do show convection building just S and SE of the center at this time, but there is still no organization that I see of consequence. Now if that convection does wrap the center we could have a slightly different story later today. Sure not going to hold my breath waiting on it though.

It's all in the pressure gradient. There is a high pressure center north of the low, and relativel low pressure south of the low. Therefore, the pressure gradient is tighter to the north of he center - thus the much higher winds there. If not for the high center to its north, the weak low would have winds of about 15 kts around the center.
