Meteorological history

An area of low pressure moved generally eastward from Oklahoma and produced heavy rains from Missouri to Ohio on February 8. By February 9, it had reached Kentucky. A new, secondary low pressure system formed over Georgia along the warm front associated with the primary low. As the secondary low matured along the U.S. East Coast, the initial center weakened rapidly, and heavy rainfall developed over the Carolinas in association with the new low. Mixed precipitation soon spread across the Mid-Atlantic States, and heavy snow began to fall from New Jersey northward by 1200 UTC on February 9.

The primary low dissipated, and the secondary low continued to intensify as it moved northeastward from the North Carolina coast to Long Island. Its forward motion slowed substantially, leading to increased precipitation totals over land. By 0000 UTC on February 10, the storm deepened to 970 millibars, having strengthened 32 millibars in an 18-hour period. At 1200 UTC, it was situated off Cape Cod, still an intense cyclone. On February 11, the storm moved out of the region.
