Astrologically, I think this deadly weather is related to the angular Uranus-Pluto square in the 2011 Aries ingress(spring equinox) chart, and the transit of Uranus to the Aries ingress Vertex- which signifies fateful encounters. I don't normally include the Vertex when casting a mundane chart, but in this case it seems to be a worthwhile factor to consider. (The May 1 assassination of Osama bin Laden in Pakistan also fits the Uranus-Vertex contact, with the ingress Vertex in the 7th house of open enemies. We might also expect retaliatory attacks from Al Qaeda in some form or another.) Uranus reflects sudden shocks/events that that are often radical and unpredictable. While Pluto symbolizes power, ruthless forces, and destructive upheavals. (The transit of Uranus to the US Sibly chart Venus(3 Cancer) might also reflect extreme weather, as Venus rules the natal 4th house.)

The Cancer ingress(summer solstice) chart for Washington, D.C., appears nearly as stressful as the Aries ingress, with Uranus on the Vertex and square Pluto. Again, the epic square is on the angles and therefore capable of producing forceful effects locally. Although Saturn is not conjunct the ingress Ascendant, it is near the star called Vindemiatrix- the 'widdowmaker', long associated with natural disasters. And as Saturn rules the ingress 4th house(weather, land, and homes), it's conjunction with a malefic star is not a favorable sign for the U.S. regarding 4th house matters.
Looking ahead, the Sept. 27 Libra New Moon is a flashpoint for major U.S. events that resonate with the intense Uranus-Pluto square. The exact nature of these prospective events is not exactly clear- but further extreme weather, earthquakes, and political upheaval are likely.
"If our current civilization were to disintegrate, we might face an apocalyptic passage, forcing us to evolve at high speed. Breakdown(Pluto) and breakthrough(Uranus) may happen simultaneously." ~Daniel Pinchbeck
