Tonight's sounding data drawn up by www.rap.ucar.edu and provided to them by the Shreveport National Weather Service shows a slight bit of instability in our atmospheric column. With temperatures close to the mid 90s at the surface, storms have been firing on outflow boundaries mainly in AR. The storms have been the pulse type and have tended to propagate on the boundaries toward the most instability or south were it was hotter.

For any more convection to fire close to our area, it will have to occur on boundaries. Diurnal temps are falling now and the atmosphere is stabilizing. Most of the rain should end later this evening although a few stray showers may linger late near the boundaries especially as the north-south one in NW LA merges with the east-west one south of HWY 82..

With the remnants of Bonnie moving by Monday and the ridge sliding more east, our rain chance is still expected to increase. Here upper atmospheric temperatures will drop and the tropical moisture should pick up. Thus, CAPE values should rise on Monday providing a big ingredient for convection.

Have a nice night.
