August 19-21, 2010 Forecast Results

Four areas were highlighted in the August 19-21 forecast for severe weather.
Aug 19b
The first area was the eastern Texas/Louisiana area. I'd been expecting tropical activity there. The above map is for August 19th. The Weather Channel reported that eastern Louisiana and southern Mississippi was picking up 1 to 3 inches of rain due to the prolonged stay of the remnants of Tropical Depression 5. On the 20th, torrential rains hit western Alabama.

Aug 21d
The next area mentioned in the forecast was the Bahamas/Southern Florida area. I expected tropical storm formation around this time. We were spared the tropical system but as can be seen from the Weather Channel map above for August 21st, strong thunderstorms developed over the area.

On the 20th the National Weather Service issued a Flood Advisory for the Miami-Dade county area as 2 to 3 inches of rain had fallen. A Significant Weather Advisory was issued for Broward county for frequent to excessive lightning and gusty winds of 45 mph. Strong thunderstorms were also reported in Seminole and Volusia counties. Today, locally heavy downpours continue over Florida.

19 Northern Plains
The third area mentioned for severe weather was the Minnesota/Wisconsin area. The above Accuweather map is for August 19th. The northern Plains was hit by severe thunderstorms and on the 20th, severe storms threatened areas from Upper Peninsula of Michigan and Wisconsin southwestward through eastern and central Kansas and northern Oklahoma.

The fourth area mentioned was the U.S. Desert Southwest in and around Arizona. On the 19th, Flash Flood Warnings and Severe Thunderstorm Warnings were issued for Utah as storm produced 1 to 2 inches of rain per hour. On the 21st, Flash Flood Warnings were issued for Arizona due to heavy rainfall. Nevada had Red Flag Warnings prompted by dry conditions and sustained winds of 20 to 25 mph with gusts up to 40 mph.
