Weather Educartion: Impacts Of The Canadian High Pressure Center
2012-12-29 11:43:39

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...

Weather Pack For September 6, 2012
2012-09-06 08:00:38

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...

Upper Air Map Identification for July 6, 2012.
2012-07-06 12:00:10

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...
