Today was a very quiet day. One group operated in Florida (Miami and Tampa Bay), monitoring ongoing convection coming off the GoM. The other group operated in the Memphis CWA, tracking sub-severe convection associated with a cold core low advancing through the region.
LAP
- Correctly increased CAPE... GFS has been underdone for CAPE each day this week, so it was nice to see LAP correctly increase the values.
- Clear sky and cloudy sky retrieval values were closer to other data sources than were GFS values.
- Convection developed within the max in LAP PW, which was maximized vertically through the atmosphere at that location as seen in layer PW
- Participants commented that they like the inclusion of GFS model data to fill holes in retreivals
CI
- Pinged development in S Florida
- It worked well for us yesterday.
- There were some that it missed, but there were hits too.
ProbSevere
- Never got out of the single digits. It was still useful information, since convection was not severe
- Having estimates of CAPE and shear were useful
- Confirmed our thinking of what the mesoscale environment would be like
- It did pick out cells within the large cloud shield
- Broadcaster: In my office, we use GR, so we could pull in probsevere files
SRSOR
- In the mid-level cloud plume along the pre-frontal trough, it was helpful to see convective clouds poking through.
- It is helpful to compare SRSOR with radar imagery to match up cells
- I liked the sandwich product, this would be helpful to watch in real-time
SRSOR winds
- The winds nicely showed the shift with drier air moving through.
Lightning Jump
- The few jumps we had were low, which fit the situation.
NUCAPS
- I looked at NUCAPS offshore, which showed drier air aloft, which made sense as drier air was moving in.
- The modified sounding over W TN showed around 500 j/kg of CAPE, which looked right, giving we confidence in how the environment had evolved since 12Z.
- With the Plan view displays it was helpful to see the environment at a particular level.
- With the plan view, you can quickly see how the airmass is changing, more or less stable, based on mid-level cooling temperatures which steepens lapse rates
- The Plan view display is most beneficial in the clear sky pre-convective environment
- I would use theta-e to diagnose areas of CSI and strong frontogenesis.
