What day did that "powerful windstorm" hit?

Just a follow-up to my previous post...

On page 156 of "The Grail Bird", Tim Gallagher writes:

On our last day in the swamp, a powerful windstorm came up . Shocking in its violence and intensity, the wind roared through the forest canopy, bending and shaking the tops of the tall trees. Huge limbs creaked and moaned and frequently came crashing down near us, causing an explosion of water. At times it felt like being in the target zone of a mortar attack. For the entire day we rarely saw or heard any birds.

Again, according to the official timeline, the Gallagher/Harrison Cache River sighting took place on 2/27/04, and Gallagher informed Fitzpatrick in person at Cornell on 3/1/04.

A reader pointed out that we can take a look at historical NOAA wind reports here (below the midpoint of the screen, there's a box where you can type in the date of your choice).

Sometime between the two dates above, given Gallagher's storm description, I'd expect to see some wind reports from Arkansas, but I don't see any until Thursday, 3/4/04.

I'm not claiming that this question is necessarily of huge importance, yet I'm curious. Again, if anyone has some helpful information on the windstorm/timeline questions, please drop me an email.
