Springfield Storms

We’re currently analyzing storms developing in the Springfield Missouri WFO.  Right now I’m using various tools to monitor if these storms will become severe.

Right now I’m using a combination of radar, GLM, nucaps, and the All sky products. Currently the most helpful tools on top of what I normally use are allsky and the lightning products.

The allsky cape helped to find CAPE gradients and an increase in CAPE. The northern batch of storms were pushing into an area of increasing CAPE and in return they did intensify.

While deciding whether or not to issue a warning I also looked at AFA GLM data to see if there were new flashes developing which can be indicative of growing convection. That flashes aligned with radar and increased my confidence that storms would intensify.

That lead to me issuing a severe thunderstorm warning. The prob severe data also ramped up. So I felt confident about my warning.

I also used NUCAPS sounding predictor to look at the cape during the rest of the afternoon.

 

While watching storms in the Springfield area I tried using  NMDA. Even after magnifying the product it was still a bit hard to see. I’m note sure if there’s a way to make the circle bigger or more pronounced. It can get busy on an active day.

As I continue to track storms I’m using Allsky CAPE to see what type of environment they are moving into. The CAPE does increase farther east so that makes me anticipate convection wane over the next few hours. I will though pay close attention to the storm farther north since they will move along the cape gradient.

I also used probsevere to increase my confidence in warning for a cell in pulaski county. The velocity ramped up as well as vil values.

 

The increase in probsevere over a few scans prompted me to issue a severe thunderstorm warning.

New development over southern MPX

With new development popping up along the outflow boundary from northern storms earlier, used AllSky and NUCAPS to analyze the environment over southern MPX’s area.  That airmass is a little drier and a little less unstable compared to where the earlier complex was.

Reissue

Have never re-issued a warning for the exact same area before.  Western cells were not moving and still very tall, so re-issued.  MESH still showing potential for quarters or a little more there.

EAX Mesoscale Type Discussion (Mountain Bone)

 

Continuing to see clearing behind the decaying MCS as of 21z. This has allowed ML Cape values to jump above the 2000 – 3000 J/KG range along and northwest of I-35 per the All-Sky Layer Convective Available Potential Energy product. This is in general agreement with 18z NUCAPs soundings with further downstream propagation of best CAPE region likely over the next few hours per the NUCAPs forecast products. With that being said, not sold on the availability of an efficient enough lifting mechanism across this region over the next few hours to get widespread initiation underway. Best chance of seeing that will be further east of I-35 where a pretty pronounced differential heating boundary exists per in-situ observations.

Convection development and location is too uncertain to entertain a watch issuance this far north as of 21z Tuesday.

FED, ENTLN comparison

Noticed the FED was matching up well with ENTLN data in our eastern cells, but then the cells to the west should have been electrically active as well.  ENTLN data shows several flashes, but FED from GLM is minimal.

McLeod Co., MN Hail

The public reported golf ball size hail 1 SW of Silver Lake in McLeod Co. at 348 pm CDT.  At this time, ProbSevere depicted 99% for severe hail, and there was a ZDR minimum within the core of the storm, and the hydro class showed giant hail as the precip type ( not shown).

Forecast NUCAPS Info

NUCAPS data indicates well the area that has received rain, and the airmass the current cluster will be going into (the colors just outside of the blacked-out area.

As we were thinking of some tornadogenesis earlier, seeing the relatively high LCLs from this product may deter us from issuing a later TOR warning.

EAX Near-Term AFD (Mountain Bone)

A decaying MCS continues to progress northeast across the central portions of northernmost Missouri, allowing for destabilization to begin in its wake. This is especially true along and west of Interstate 35 in NW Missouri/eastern-most KS where clouds have cleared for several hours according to GOES_East Channel 2 imagery. With in-situ observations showcasing upper-60s to low 70s dewpoints at the surface across the central and eastern portions of the state, it likely won’t take much in the way of surface heating to allow for convective initiation this afternoon and evening.  Based on downstream NUCAPs soundings, rather robust SFC CAPE values in the 3000 – 4000 J/KG range will likely spread northwestward with time, which should be ample to support some convection this afternoon and evening. Best (early) thoughts on initiation location this afternoon will be across the easternmost portions of the CWA along a line from Boonville to Centerville along the eastern most periphery of the nearly stalled MCS, which could provide for enough lift to get things firing by late afternoon and evening. Also keeping an eye on a downstream shortwave clearly evident in GOES_East water vapor imagery which could push an additional round of multicellular convection through late this afternoon and evening. Most likely to brush the southern and eastern portions of the CWA, which currently finds itself adjacent to a severe thunderstorm watch extending to its south and eastward. .

Any storms that do form or push into the area should have plenty of moisture and instability to sustain themselves. All_Sky TPW and NUCAP soundings show a plume of 1.3 to 1.5 inch PWATT values extending north throughout the entire CWA, which also brings the concern for some additional flooding, especially across the southeastern portions of the CWA which will likely see more numerous coverage of storms. Low 0-1km and 0-6km effective shear values should limit the presence of sustained supercells, however, a strong to severe thunderstorm or two will remain possible this afternoon and evening.
