Looking at the weather map above we can see that we have three and four digit numbers on the map. These numbers are known as Sea Level Pressure. They are recorded in MB. Looking at the Northern part of South Dakota we see a number at 995mb while over parts of Maine we see the number closer to 1020mb. So we would say that high pressure is over Maine, while low pressure is over the Dakota’s...
On June 17, 2012 a line of strong storms began to develop around 5pm CDT. These storms started forming multiple funnel clouds with one confirmed tornado that hit near a small town called PeeverSD. The size of the tornado has not been confirmed yet. There is one report of damage of a pickup truck and trailer thrown into the ditch off the I-29 interstate. Also multiple houses have loss portions...
Atlanta Georgia is located in the Southeast part of the United States, which supports a warmer summer with showers and thunderstorms. The winter months can be colder due to its higher elevation than the coastal cities of Georgia. Temperatures for Atlanta GA: January through February, which is the peak of winter for Atlanta, sees average lows around 30 with daytime highs near 50F. March and...
Onshore flow describes the movement of any weather feature moving towards the shore. The most common weather features that are affiliated with onshore flow are Hurricanes and the daily sea breeze. What happens with a hurricane is the Northeast side of the storm will produce winds out of the Southeast to South which will force the ocean water (Storm Surge) towards the coast along with all the...
As of 2:30pm Friday afternoon an area of disturbed weather has intensified in coverage over the Northeast Gulf of Mexico. At this time the NHC has given the area a 0% of development. As it continues to track westward across the Gulf of Mexico it will bring increased winds/seas and heavy precipitation to the area. Severe weather also can’t be ruled out with this system as it continues westward...
Cumulus clouds are white in appearance and are formed when warm moist air near the earth’s surface is forced aloft by day time heating. Cumulus clouds are usually associated with nice weather, however if they continue to grow and get more moisture and instability with them they can turn into Towering Cumulus and CB clouds which would change the weather to increase the chance of seeing...
The first topographic feature that I would like to talk about today is the Rocky Mountains. The Rocky mountains with their rugged terrain and high elevation can really become a large impact on weather patterns in the United States. First, the Rockies provide the Central Plains with the cold air aloft that is needed in the formation of severe weather to include tornadoes. Secondly, the...
Tropical Storm Beryl, the second named storm of the Atlantic Hurricane Season 2012, began in advance of the actually start of the season. On the evening of May 25, 2012 Beryl started out as an area of Low pressure off the Southeast Coast with an estimated pressure near 1002mb. Beryl further moved southeastward towards the Florida coast near Jacksonville. Beryl also intensified into a...
When it comes to learning about the weather it is very important to understand about the oceans. The reason for this is that ocean currents can play a major role on not only weather but also the climate of a region. The current that we are looking at is called the Loop Current. If you look at the image above you can see that it’s situated just off the west coast of Florida and extends into...
GULF COAST UNITED STATES The weekend of June 8-10, 2012 was one of the wettest weekends in a very long time for this region. Thunderstorms and very heavy rain started in the middle of the afternoon on Friday and continued all the way through Sunday Night. An upper level feature began to slide through Eastern Texas towards the Gulf of Mexico and this interacted with a quasi-stationary...
