Local Studies & Presentations:

                          A 3D view of the reflection of a rear inflow jet descending into a storm forcing it to bow out at the ground, using GRAnalyst Software, on March 8, 2009 in Southeast Missouri. This storm produced a tornado that crossed from Bollinger into Cape Girardeau counties.

Part of what we do includes research of old cases to learn how to do better in the future. Our goal is to improve the knowledge and confidence of the forecasters to help them issue timely, accurate warnings.

Observed Tornadoes

For those who have lived in this area for a while, this is nothing new. However, if you are new to the area it may come as a surprise that severe weather is so common. It is not unusual to have severe weather at any time of the year. Below are graphics that depicts when tornadoes have occurred in our county warning area by year and by month.

Additional Information

Local and regional studies are on-going concerning the severe weather in the southeast U.S. At the forecast office in Paducah, we have been studying cool season tornadoes for several years. We consider the cool season to be during the months of November, December, January & February.

For the general public we suggest that keeping an eye on the weather can give you hints as to when tornadoes are possible. If is it warm and humid outside and it is unusual for that time of year...be aware that severe weather may be possible in the next day or two.

To back this statement up, we have been looking at dew point temperatures in Paducah and comparing that with severe weather within our county warning area. The dew point is a measure of the amount of moisture in the atmosphere. During the winter, it may "feel humid" when the dew point temperature reaches 60 degrees. During the summer, we commonly experience dew points in the 70s, but during the winter, when it is generally cool, the days with 60 degree dew points tend to stand out. Our studies suggest that the chances of severe weather increase dramatically when the dew point temperature is in the 58 - 64 degree range in the cool months.
