Description:"Forecasting and warning for flood and flash flood producing rainfall is a great challenge for operational meteorologists. Reviewing flood events is an important step in improving our ability to evaluate flood potential. This case illustrates the complexities involved in diagnosing flood potential. Depending on atmospheric moisture, stability and wind characteristics, warm season closed 500 hPa lows can produce a wide variety of weather. A slow moving closed upper-level low spawned scattered flooding and severe weather as it crossed the northeastern United States during 14-16 July 2000. While this by itself was not an unusual pattern, this was an especially interesting case for two reasons. First, copious amounts of rain fell (three-day rainfall as high as 30 cm [12 in]) in parts of eastern New York and western New England. Second, with the passage of the upper low, distinctly different mechanisms combined to generate flooding rains on each of three days. Using available synoptic and mesoscale data, we will examine how subtle changes within this large scale upper low resulted in substantial changes in sensible weather"--Abstract.
