Lightning jump and high dvil values prompted to svr

First srv of the day across the OAX area based on lightning jump, cold cloup tops and dvil values.

Derived CAPE

Increasing levels of CAPE showing up on the derived GOES-16 product. CAPE values from the GOES data shows 1700-1900 in the central part of the CWA. This matched pretty well with the 18Z special sounding which was around 1500.

Sampling on VIS

Sampling on VIS now gives a percentage where on GOES 13/15 it gave a count. The count is frequently used on GFE tools for populating SKY grids. Either the GFE toolk that uses this needs to be updated or sampling needs to include count. -ams

NuCaps Compare - TOP

20Z TOP Sounding

1834Z NuCapps Sounding near TOP

For comparison. Steeper mid-levels in reality. NuCAPS misses the mid-level Capping inversions. TPW is pretty close to the Derived TPW from ABI.

ABI Cirrus Ch 4

Here is an example of thin cirrus that is more visible over PA than on the CH2 Red VIS image. Top image is the Ch4 -ams

pre storm enviroment

Starting off with a relatively stable environment, especially over the southern CWA. SGF and OAX soundings (TOP not available) showed with heating instability would increase. Will track the evolution of CAPE with the derived product. Favorable shear for supercell development.

Fire Temperature RGB

So outside of my operational area today but checked out the Fire Temperature RGB of a fire back in NC. Very cool and useful to see the the flare up of the fire. Even as wide view it stuck out.

NuCaps/MET OP sounding Locations thought

Generic comment.

Need some location ID on these sounding. Hard to remember which 'dot' one actually chose. Only one sounding at a time now but someday it may be more.

Reference in upper left of Lat/Lon isn't quite good enough.

Which dot is it?

Outflow/TPW/MetOPs A

Series of pictures showing the derived TPW picking up on increased moisture behind an outflow boundary. Lower dewpoints in the post outflow area (mid/upper 60s) vs. ahead of boundary (70-72). Soundings show the lower TPW in southern MO vs. higher TPW near Topeka (like the derived ABI). Actual numbers are little different but trends similar.

17Z TPW

 Springfield area.

EWP Week 2 Day 4

Participants will be working out of the Omaha, NE and Topeka, KS CWAs today.
