April 6-19, 2024 | Severe Weather


Recommended Posts

High ceiling but low floor kind of day. May not be a lot of storms but the ones that do form could be significant tornado producers, especially in KS and NE. 

Significant cloud cover here in OK so far

Well - first light revealed the carnage that was our last nights storm. Look like I took a hit from a damned bomb - stuff scattered everywhere. Even old timey completely iron lawn chairs - tossed aside some 5 yards from where they had been. Those chairs never move in any normal level winds. 

Then, the old "tin" roofed pavilion. Nearly a full third of the roof panels had been lifted and, go figure - 75 year old annular nails could not hold the ancient oak framing. I spent nearly the entire day refastening with grommeted ringed nails. 

Some of my local weather followers are asking me if we had a "nado" last night. I'm telling them no - but it's hard to convince some of them.

 DISCUSSION...As of 2355 UTC, regional radar showed multiple clusters
   of storms, and occasional supercell structures, ongoing across parts
   of central and eastern VA. The environment ahead of these clusters
   remains broadly favorable for damaging winds and hail given 500-1000
   J/kg of MLCAPE and 35-40 kt of effective shear. Recent hi-res
   guidance suggest the ongoing clusters will continue to track
   east/southeast this with gradual upscale growth. Damaging gusts
   appear to be the most likely hazard with storm interactions and
   relatively modest boundary-layer moisture present over parts of
   eastern VA. However, severe hail should still remain possible,
   especially with any supercellular elements, given robust mid-level
   lapse rates of 7-8 C/km. The strongest activity should remain
   focused over the southern half of the Watch area, though more
   isolated development will remain possible on trailing outflow and
   over the higher terrain in western VA/WV through the next few hours.

It was those "damaging gusts" what got us last evening.

Storms are finally developing in the eastern panhandles/western Oklahoma. The environment... whew.

Whatever that was, failed to be sustained. Guess it's not surprising given this mid-level profile was being advected into the area.

Parameters are pretty good right now for severe weather today

I feel like I’m the only person in Ohio that’s watching this lol… maybe I’m missing something.

95% probability.

   Areas affected...portions of eastern IN into central OH

   Concerning...Severe potential...Tornado Watch likely 

   Valid 171550Z - 171715Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Severe potential will increase over the next 1-2 hours
   across parts of eastern Indiana into western Ohio. All severe
   hazards will be possible and a tornado watch will likely be needed
   in the next hour.

   DISCUSSION...Heating into the upper 60s to low 70s and dewpoints in
   the low 60s is resulting in modest instability (MLCAPE up to 1000
   J/kg). Effective shear magnitudes greater than 40 kt will support
   organized convection, with supercells and some small line segments
   possible. Damaging gusts to 65 mph and large hail to 1.5 inches in
   diameter will be possible with this activity. Additionally, some
   backing of low-level flow is possible, especially into parts of Ohio
   this afternoon. Forecast and regional VWP data indicates enlarged
   low-level hodographs. Steepening low-level lapse rates and
   increasing 0-3 km MLCAPE with time amid favorable low-level shear
   will support tornado potential in addition to the wind/hail risk. A
   tornado watch will likely be needed within the next hour.
