High-Risk Days of the 1980s and 1990s:

April 06, 1972, the Severe Local Storms Unit of the National Severe Storms Forecast Center began issuing a new forecast product designed to provide an at-a-glance assessment of the thunderstorm potential across the continental United States. Early outlooks were quite simple. As forecasting technology improved, the outlooks became more detailed. The modern Storm Prediction Center convective outlook provides a complete breakdown of where thunderstorms/severe thunderstorms are expected, why they are expected, what the main threats are expected to be, and more.

Modern convective outlooks divide the thunderstorm potential into four threat levels. General (non-severe) thunderstorms, slight risk of severe thunderstorms, moderate risk of severe thunderstorms, and high risk of severe thunderstorms. This archive focuses on those days when a high risk was included in the outlook, because a high risk is only issued when the forecasters expect a major (perhaps even historical) tornado outbreak and/or damaging convective windstorm (derecho).

This section includes those high-risk days prior to 1999. Any high risks issued before 1988 are missing because of a lack of information. The archives are quite sketchy up until about 1997, because there are relatively few convective outlooks and storm chaser accounts still online for the older events.

March 13, 1990:
We could not find any references to the outlook risk level on this day, much less any actual SELS/NSSFC outlooks.  We have been told that it was a moderate risk event.  A massive 59-tornado outbreak (including 2 F5s, 2 F4s and 10 F3s) across Kansas, Oklahoma, Nebraska, and Iowa. Casey Osburn sent me this message:
I remember in ensuing days, there was talk among my meteorologist friends that it certainly *should* have been a high risk due to the results of the day. But March 13, 1990, was most certainly a moderate risk for portions of the central plains. And back then (as you probably know,) if there was a high risk, then there was no moderate region...a slight risk would surround the high risk region.

Omega, Oklahoma Tornado Video

June 01, 1990 It is my understanding from some meteorologists and severe weather researchers that June 01, 1990 was a high risk day that ended up as a bust.  Casey Osburn has sent me an email with the following information:  June 1, 1990, there was a high risk along the high plans from North Dakota to west Texas...total bust. This was the precursor to the high risk further east on June 2. Only a couple of watches were issued on June 1, but no significant tornadoes happened on this day.


June 02, 1990:
A major tornado outbreak struck the Ohio Valley and Midwest during the evening into the overnight hours of June 02-03, 1990. 55 tornadoes including 7 F4s touched down. Nick Smith has kindly provided a wealth of information about the outbreak, including saved radar images and screenshots from The Weather Channel's coverage.

There is a well-known video of a tornado in this outbreak that was so picturesque that storm chaser Doug Speheger, a member of Howard Bluestien's research team exclaimed "Ooh, what a classic!"  Few NSSFC products are available.

Kingfisher, Oklahoma Tornado Video


April 26, 1991:
Significant Kansas/Oklahoma outbreak that made the 12th seem like a fair-weather day by comparison. Three of the approximately fifty tornadoes have been immortalized either by the scars they left on the communities they affected, by the incredible video taken of them, or both. These are:

The Andover, Kansas tornado, which devastated a trailer park in that community, killing 13. This tornado also hit McConnell Air Force Base and parts of south Wichita. This tornado was among the most destructive in recent memory (perhaps not surpassed until May 3, 1999) and was rated F5.

The tornado near Red Rock, Oklahoma. It fortunately occurred mostly in open country and received an official rating of F4, but the mobile Doppler radars measured winds of 287 MPH within the vortex, which is in the F5 estimated wind speed range.

The Kansas Turnpike Overpass tornado. This was produced by the same supercell that spawned the Wichita/Andover tornado mentioned above, but contrary to what some sources will tell you, it was NOT the same tornado. It also was not a violent (F4 or F5) tornado. It did roll and tumble the cars and trucks in its path along the highway, but it did not loft them into the air and throw or carry them long distances, which is a characteristic of violent tornado damage. It also did NOT pass directly over the people taking shelter under the bridge. The acceleration of the wind seen in the video is due to inflow blowing toward the tornado. The highly publicized and incorrect notions that the tornado was violent and made a direct hit on the bridge is responsible for a widespread public belief that overpasses are safe shelter from tornadoes. More recent disasters have shown that this is not necessarily the case.

March 08, 1999:
As is rather common with early season situations (January 21 was a major exception!), marginal instability prevented cellular convection from forming in extreme-shear environment and a squall line was the dominant storm mode. There were a couple of tornadoes in addition to some severe wind and hail, but severe weather was not widespread enough to justify a high risk.

Widespread damaging straight-line winds were more prevalent on the 5th, with fewer tornadoes than the previous 2 days (18 compared with 39 on the 4th and 77 on the 3rd), but three people lost their lives to an F4 tornado in Tennessee.

Nashville, TN NWS Summary

Wikipedia Article


Note: Starting with June, 1999, SPC Preliminary Storm Reports are available on-line in their entirety, so I will be linking to the full listings, rather than to forecaster John Hart's graphical archive.
   


June 05, 1999:
Although the forecasted major outbreak never materialized, a few photogenic tornadoes developed in Nebraska and South Dakota. Several chasers had successful trips. The same storm system brought another round of widespread severe weather to the upper Midwest on the next day, when Andy came face to face with it.
