For the rest of today, low pressure system over Oklahoma will be accompanied by a trough pointing northwards. That trough should be the initiation of some showers and snow showers as they pass through. The low pressure will also put in energy to assist the development of this precipitation.
There will be a risk of severe weather today which will be outlined in a post soon. It does appear a warm front will be the result of the severe weather.
Today, warm temperatures will exist across the South US, but accompanied with clouds as the low pressure passes.
Low pressures over the Rockies will create mountain snows and rain in lower elevations. A storm off the West Coast will also begin to create problems along that area.
