The Rockies will be hot and the West Coast will be warm and dry. The Pacific Northwest will remain mild and dry.

Severe Weather: There will be a wide area for potential strong to severe storms from the Great Lakes into the Northeast and then back through the Gulf Coast and Southeast. The biggest threat looks to be damaging winds and hail.

Major Weather Impacts Discussion for July 19, 2013:

Day 1-3: A storm system moving through the Great Lakes will bring showers and thunderstorms to the region. These storms will extend into the Northeast and also along the frontal boundary back into the Gulf Coast. High pressure will keep the weather nice from the Plains to the Rockies and over most of the Western United States. Day two the frontal boundary will push into the East Coast and the storms will extend from the Northeast to the Gulf Coast. Afternoon showers and thunderstorms will also impact parts of the Plains region. The period will finish with storms over the Mid-Atlantic back into the Gulf Coast, another storm system pushing into the Northern Plains, and the southwest monsoon bringing more showers to the Southwest.

Day 4-7: The period will start with showers and thunderstorms over the Southeast and Gulf Coast. High pressure will push through the Great Lakes and Northeast. A cold front will bring showers and thunderstorms to the Northern Plains. A few showers will be possible over the Southwest. Day five will have a new low pressure forming along the Mid-Atlantic and the cold front pushing into the Northeast. This will bring an area of heavy rainfall to the Northeast and Mid-Atlantic regions. The period will finish with another low pressure area moving through the Plains towards the Great Lakes bringing showers and thunderstorms to the region.

Day 8-12: The period will start with low pressure along the East Coast bringing showers and thunderstorms to the region. The stationary boundary will extend along the Gulf Coast. High pressure will be over the Northern Plains. A new storm system will begin to develop over the Southern Plains. Day ten the frontal boundary along the East Coast will bring heavy rainfall to the Mid-Atlantic region. Showers and thunderstorms will be over the Gulf Coast as well. There will be a few showers and thunderstorms over the Northern Plains. The period will finish with a strong piece of upper level energy moving over the Gulf Coast that will bring possible severe weather to the region.

Long Range Outlook: The long range will start with a low pressure over the Southeast and the cold front back into the Gulf Coast bringing showers and thunderstorms to the region. The middle of the period will have a storm system moving through the Ohio River Valley and Great Lakes extending to the Gulf Coast. This will be the focus for showers and thunderstorms. A tropical wave will be pushing towards Puerto Rico. The period will finish with the tropical wave entering into the Gulf of Mexico.

Ask The Weatherman for July 19, 2013:

Question: What are gust fronts?

Answer: This feature is a group of clouds that develop ahead of a thunderstorm. What happens is that as the thunderstorm gets stronger the winds and rain begin to sink in the storm. As this occurs it begins to push the clouds ahead. The cloud that we see looks like a horizontal rolling cloud. As this cloud moves through the winds will increase. Reports have been of this cloud bringing winds in a range of 45mph (weaker storms to well over 100mph the stronger storms). These clouds can also create straight line wind damage.
