On Monday 02/23/04 I posted:

.....The SOI had shifted back to positive a month or so ago and the end result was the cold period between 2/15-20/04 and a less potent subtropical jet stream and therefore weaker low latitude winter storm systems. As an end result here in SW Plant City I've measured only 0.90" of rainfall so far this month. By the way there is an approximate three week lag in sensible weather after the SOI switches sign. Well the SOI has now shifted back to negative again and you guessed it a return to a more potent subtropical jet stream and stronger winter storm systems. And just in time for Florida's severe weather season peak. In any event the (STJ) subtropical jet stream is definitely strengthening again and California can verify that fact, as they have getting slammed by a series of strong winter storm systems deep into the south. Looking within the STJ there are at least four shortwave impulses racing across the southern part of the country towards Florida.....

On 02/24-25/04 here is the result: http://www.kn4lf.com/sub/02242503rainfalltotal.gif Widespread heavy rainfall with a very large coverage area of 3.00-4.00+" with some totals exceeding 8.00", falling in 18 hours, with lot's of severe thunderstorms, straight line wind damage and possibly 6 tornadoes. A classic El Nino winter storm.
