Big Story Weather from September 9:
Yesterday was another hot day over the middle of the United States with temps soaring into the upper 90’s and heat index values near 105F. Flooding rains were also a big concern as places in the Rockies saw well over 3-5 inches of rainfall leading to large flash flooding events. Cold weather was a big impact as well with some places in the Northeast getting into the lower 30’s last night. Severe weather was fairly limited; however we did get the largest hail of 1.0 inch in both Michigan and Southern California. The strongest damaging winds came from Nebraska with wind gusts around 80mph.
Big Story Weather Discussion for September 10:
Surface Map: High pressure off the Mid-Atlantic coast will bring return flow over the Southeast and a few thunderstorms. An upper level ridge over the middle of the United States will be responsible for another hot day with high temps in the upper 90’s and heat index values soaring over 100. Low pressure near the Baja will bring another day of monsoonal rains to the Southwest including Colorado. A strong cold front moving through the Plains and Western Great Lakes will be the focus of heavy rainfall today along with severe weather.
Severe Weather: Today we will be watching an area over the Southeast mostly for heavy rains and damaging winds. There will also be a large area of potential severe weather from the Plains into the Great Lakes along the frontal boundary. This area will mostly be damaging winds, large hail and heavy rainfall. The third place will be over the Southwest where there will be strong winds along with flash flooding.
Flooding: There will be a high chance for flooding over the Southwest today as monsoonal rains unleash heavy rainfall.
Heat: A strong upper level high over the middle of the US will be responsible for some very dangerous heat over Iowa to the Chicago and Detroit areas today as high temps soar into the 90’s and heat index values reach 105F.

Ask The Weatherman for September 10, 2013:
Question: What are some types of low clouds?
Answer: Low clouds come in two classes. The first is Stratus and the second is Cumulus. . If you get up in the morning and you see that it’s foggy out, those are stratus clouds on the ground. When you see white puffy clouds in the sky, those are cumulus clouds. When you see large puffy white to dark clouds, those would be the cumulus-nimbus clouds – storm clouds. These are just a few examples of low clouds.
