Tornado forecast spring 2011

March 2, 2011 at 12:32 pm

Tornado production is a result of Lunar declinational tides pulling air masses from more equatorial areas into the mid-latitudes, so the peak production times when they form can be predicted as the periods from Maximum North culmination to three days after, a couple of days when the moon crosses the equator headed North, and as the moon reaches maximum South declination and several days after.

These effects are due to the production of the primary and secondary tidal bulges in the atmosphere, that arrive at the same time as the ion content of the air masses reaches a local maximum. Between the induced charge differential between the +ion concentrations riding on the more equatorial sourced air mass, established ahead of the dry line front of -ion concentrated more polar air mass, that sweeps in from the West, forcing the precipitation into the rapidly moving narrow band of severe weather from which the tornadoes form on the trailing edges.

The periods when these effects will be most likely to occur this spring,
2-25/28 for three days, which we just had, around max South.
3-5/7 slight chance of small outbreak
3-12/17 starting in Arkansas through Kentucky and the Ohio river valley
3-25/30 Starting Texas/Oklahoma/Arkansas through Ohio river valley the beginning of a long period of very wet activity most of April.
4-5/8 start up of activity
with the re-enactment of the 1974 outbreak most possible in the period
4-8/13 Maps of the expected precipitation can be found on my site, bearing in mind that the tornado and severe activity usually forms in the fast moving part of the frontal and not usually in the areas of heaviest total daily precipitation.

On the maps show on my site you can expect to see the tornado development in the areas with the “netted” looking precipitation patterns due to the usual nature of the part of the front where they occur.

1974 is one of the analog years for my forecast method, which is why I mention we may see a replay of that out break. It is also why I am in Mesa Az., instead of Kansas this spring.
