LAP Total PW and Good Sampling with Clear Skies.

The 4 panel image below shows the cursor readout over the middle of the Memphis CWA. The LAP total precipitable water image in the lower right shows a plume of modest moisture entering the CWA, moving southeastward with a pre-frontal trough. This is associated with showers developing, with the CI product (not shown) showing some lower end probabilities. This image also shows no CAPE in the upper right image, with positive LI values (stable airmass) in the lower right image. The upper right image shows good sampling of the airmass ahead of the pre-frontal trough, with mainly clear skies. These images suggest that a stable airmass remains over the area, despite the modest moisture plume moving into the area with the pre-frontal trough. It may be tough to get convection to initiate given how stable it is at the moment. JJW
