redOrbit Meteorologist Joshua Kelly Big Story Weather from October 8: The big chill has been on for a good portion of the United States east of the Rockies, while the west is still dealing with very dry conditions in places like Portland and Seattle and also the Southwest. A weak frontal boundary moved through the Northern Plains last night and dropped a few sprinkles across the region. Weather Outlook for October 9: Low pressure moving north of the Great Lakes today will bring...
redOrbit Meteorologist Joshua Kelly Big Story Weather from October 5-7: The big story from the past three days has been the arrival of cold polar air into the United States. We are slowly going to see this modify before the next shot comes in later this week. Frost and freeze warnings have been expanded down into the Southern Plains and eastward across a good portion of the Ohio River Valley. Severe weather was very limited this past weekend due to all the colder air in place,...
NASA's Hurricane and Severe Storm Sentinel or HS3 scientists had a fascinating tropical cyclone to study in long-lived Hurricane Nadine. NASA's Global Hawk aircraft has investigated Nadine five times during the storm's lifetime. NASA's Global Hawk also circled around the eastern side of Hurricane Leslie when it initially flew from NASA's Dryden Research Flight Center, Edwards Air Force Base, Calif. to the HS3 base at NASA's Wallops Flight Facility, Wallops Island, Va. on Sept. 6-7, 2012....
redOrbit Meteorologist Joshua Kelly Big Story Weather from October 4: The first big winter storm of the season has now pushed into Canada.

The cold air was a big story as some places in Montana and the Dakotas dealt with overnight lows into the 20’s. Weather Outlook for October 5: The frontal...
NASA's Aqua satellite provided two different infrared views of the two tropical storms swirling in the Atlantic Ocean. Oscar is battling wind shear that appears destined to tear it apart, while Nadine is merging with a cold front. NASA's Aqua satellite passed over both Tropical Storm Nadine and Tropical Depression 15 (TD15) on Oct. 3 at 1553 UTC (11:53 a.m. EDT), before TD15 became Tropical Storm Oscar. While overhead, the Atmospheric Infrared Sounder (AIRS) instrument aboard Aqua captured...
NASA satellites continue to gather data from Tropical Storm Nadine on its twenty-second day of life in the eastern Atlantic as it threatens the Azores again. NASA data has shown that wind shear is pushing the bulk of clouds and showers away from Nadine's center of circulation A tropical storm warning is in effect for the Azores. The National Hurricane Center (NHC) expects tropical storm conditions associated with Nadine to spread over the northwestern Azores during the night hours on Wed....
redOrbit Meteorologist Joshua Kelly Big Story Weather from October 3: Polar Storm “1” has been moving through the upper Plains and Western Great Lakes bringing with it periods of cold rain, rain-snow mix and also snow to North Dakota and Northwest Minnesota. Some places have started to pick up anywhere from a dusting to a few inches. Severe weather was very limited yesterday as there was only one report of hail in Southern Illinois. Other than that it was a quiet day. Big...
redOrbit Meteorologist Joshua Kelly Big Story weather from October 2: The cold air has started to invade the Northern Rockies and will continue to push southward over the next few days. A quiet day with only one isolated wind report in the Carolina region. Other than that the heat in the Southwest continued. Along with that we had Red Flag Warnings over the Northern Plains with the strong dry southerly winds impacting the area. Weather Outlook for October 3: A few lingering showers...
Forecasters know that Tropical Storm Nadine is a fighter as it continues to stay alive in the eastern Atlantic Ocean. Even satellite imagery shows Nadine's fighting spirit, because although Nadine is now a tropical storm, infrared data clearly shows that Nadine maintained an eye early on Oct. 2. At 11 a.m. EDT on Oct. 2, Nadine remains a tropical storm and appears to be weakening. Nadine's maximum sustained winds were near 65 mph (100 kph). The center of Tropical Storm Nadine was located...

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...
