Springtime showers and thunderstorms dumped heavy rains over parts of
northwestern Arkansas and south central Missouri over the weekend.
Hardest hit was northwestern Arkansas where two children were swept
away by flood waters west of Huntsville, Arkansas. A stationary front
draped across central Arkansas from northern Texas to the Mid-Atlantic
region provided the focus for strong storms as southerly winds pumped
low-level moisture up from the Gulf of Mexico.
The Tropical Rainfall Measuring Mission (TRMM) satellite uses both passive and
active sensors to examine rainfall from space. The TRMM-based, near-real
time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard
Space Flight Center monitors rainfall over the global tropics. MPA
rainfall totals for the period 23-25 April 2004 show up to a foot of
rain (dark red areas) may have fallen over the northern Ozarks near the
Arkansas-Missouri border. The heaviest rains fell on the evening of
Friday the 23rd and early morning of Saturday the 24th (local time).
TRMM is a joint mission between NASA and the Japanese space agency JAXA.

An early spring storm system advanced out of the Southern Plains in mid-March 2008, causing widespread flooding. Strong southerly winds developed ahead of an area of low pressure located over the Southern High Plains and drew moisture up from the Gulf of Mexico across Texas and Louisiana. This warm, moist air collided with a frontal boundary, producing repeated bouts of thunderstorms and heavy rain from central Texas through Oklahoma and into Kansas and Missouri.
