redOrbit Meteorologist Joshua Kelly A potent weather system has been impacting regions from the Great Lakes to the Atlantic Seaboard. Where did this thing start and why was it so strong? The first thing we will look at is the 300mb level upper level wind flow chart analysis which shows us the winds associated with the Polar Front Jet. The reason it is important to look at this chart is because we need to evaluate the strength of the cold air being pushed southward. (Image...
redOrbit Meteorologist Joshua Kelly Big Story Weather from October 17: The front worked its way south overnight through Tennessee, Arkansas and mostly Mississippi, leaving a few tornadoes in its wake. There were reports of a lot of damage and also some injuries due to the tornadoes that went through Northern Mississippi.

The Canadian High pressure center shifts into the United States throughout the year and has a major impact on the weather from season to season. In the summer when this high pressure moves in, the temps usually cool off by about 10-15 degrees. For example: if the temp was 91F in Fargo, it would cool down into the 70s once this high moved in. The high also creates drier weather. In winter when this system moves in the weather pattern is the same in that the temps will drop and the air...
A look at the temps from the 4th show that another colder pocket of air is moving into the region. Aug 29: The max temps warmed to 1C, while the overnight lows dropped to 0C. Aug 30: A burst of colder air was over the polar cap as high temps only made it to -3C, and the overnight lows dropped to -6C. Aug 31: Brought a touch of warmer air back into the region as high temps rose back to 1C, while the overnight lows hit -2C. September 1: High temps again rose to 1C, while overnight lows...
Today on Weather Pack we are going to examine the surface wind around a mature low pressure system, which means that the low pressure has an occluded front associated with it. Yellow Star: The forecasted surface winds would be out of the Northwest as the flow behind the low is counter-clockwise. Green Star: Anyone that is forecasting for the green star would be looking at the winds coming from the South-Southeast just right ahead of the warm front of the low pressure system. Red...
Looking at the upper air map for the entire region from Alaska to the Atlantic Ocean we can identify a few significant features. The first is the deep low height center over Alaska, this is telling us that at 30,000ft the air is rising upwards allowing for the surface low to still be gaining strength. Also if you look to the west of that closed low you will see what is referred to as a jet max getting ready to enter the base of the low height center. This will further amplify the low...
The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...
