Big Story Weather from October 18-20:

Severe weather was very limited over this weekend. There was some snow in the Northern Rockies. There were also some frost/freeze reports all the way down into the northern part of Alabama and Mississippi.

Big Story Weather Discussion for October 21:

Surface Map: Low pressure moving through the Great Lakes will bring rain showers to places like Chicago and around the lakes. Behind it a brisk area of high pressure extends from Texas northward into Minnesota. This area of high pressure is responsible for some very cold air. A new low pressure area will be pushing out of the Rockies and into the Plains. This area will bring rain and snow to the Northern Plains. High pressure will dominate the weather over the West Coast. A strong temperature gradient along the Gulf Coast will produce a few showers today.

Severe Weather: No severe weather for today.

Winter Weather: There will be rain and snow over the Northern Plains. Snowfall accumulations should remain below 3 inches. Frost/freeze warnings will be in effect for the Great Lakes. Another area of frost/freeze warnings will extend from Northern Mississippi to Maryland.

Flooding: No flooding expected today across the country.

Tropical Weather: No forecasted impacts today.

Winds: Strong gradient winds will be over the Great Lakes today with winds around 40-50mph very possible for some locations.

Ask The Weatherman for October 21, 2013:

Question: What is a blocking high?

Answer: When you hear the meteorologist use the term “blocking high,” what they are referring to is a high pressure center that has been cut off from the jet stream pattern causing the high pressure to stall in the area it’s at. This can lead to significant weather issues for the region that has the high pressure center such as very warm or cold and dry weather. The regions to the west of the blocking high will see ample amounts of moisture as the rainfall or snowfall gets stuck.

To the west of that a low pressure area moving over the Great Lakes will bring snow showers to parts of the lakes. High pressure over Texas will bring a cool but sunny day to the region. A few showers will be along the Gulf Coast as well. A new low pressure area moving into the Northern Rockies and Northern Plains will bring rain and snow showers to the region. The West Coast will enjoy high pressure. Day two a few showers will remain along the Gulf Coast. A potent high pressure area will bring another round of cold weather to the Plains and also the Mississippi River Valley and over to the Ohio River Valley. The period will end with a few snow showers over the Western Great Lakes. High pressure over the Southeast will keep the region dry and cool. This will extend into the Eastern US as well. Another shot of cold Arctic air will push southward with the next high pressure center over the Northern Plains bringing another round of cold weather. The West will remain dry and mild.

Day 4-7: The period will start with a few snow showers over portions of the Mid-Atlantic region. High pressure will dominate the weather from the Plains to the Gulf Coast with more cool to cold weather. The West will enjoy another day of high pressure and mild weather. Day six high pressure will slide into the Southeast allowing for a shot of cold air and snow showers to move into the Great Lakes again. The West will remain dry and mild.

Day 8-12: The period will start with high pressure along the East Coast and into the Gulf Coast. A powerful storm system will arrive into the Northern Plains bringing rain and snow to the region. Some snowfall could become heavy. Day nine low pressure will extend from the Great Lakes to the Gulf Coast. Look for rain and snow over the Great Lakes becoming rain over the Mid-Mississippi River Valley and even a few thunderstorms along the Gulf Coast. Strong high pressure will bring the Rockies another shot of cooler air. Day ten heavy rainfall will be along the Gulf Coast and another clipper system bringing snow showers to the Great Lakes. Day eleven a strong storm system will be over the Northeast with heavy rainfall and a few places getting some snowfall as well. A new clipper system will be pushing into the Northern Plains with rain and snow showers.

A tropical feature will be moving towards the Baja bringing rain showers to the region. The middle of the period will have high pressure over both coasts. A storm system will move through the Plains bringing rain and snow showers to the region. This will extend into the Northern Rockies as well. The period will finish very active with multiple storm systems moving through the country.
