Overnight Forecast Discussion: April 5, 2012

Hotspot Tonight: Southeast
As a string of storm systems move offshore, showers and thunderstorms will remain in the area, thanks in part to a trough still stretched into Louisiana that should keep skies cloudy for a bit. Severe weather is possible, but not too likely with the loss of daytime heating.

Central/Southern Plains
A low pressure system with attached trough will be moving into the area. While no precipitation is currently expected due to the proximity of the system to the dry, cold mountain air, it requires watching for a severe weather threat in the near future.

Rocky Mountains
Snow and rain showers are expected in the mountains tonight as a couple storm systems and attached troughs move through the area.

Severe Weather Ongoing in Southeast

Severe storms are ongoing in the Southeast this afternoon as a cold front progresses eastward and crashes into warm, humid Gulf of Mexico air. Just taking a brief glance at frontal positions and isobars, it looks like the areas that are most in line for severe weather are mainly along the horizontally positioned frontal boundary as well as northern mississippi and places around that region.
To the south, some lower dewpoints reside, making the area a bit less favorable for severe weather.

Severe Thunderstorm Warnings for Mississippi, Louisiana

Severe thunderstorms are moving into mississippi at this time in the form of a bowing segment. a frontal boundary is currently moving east, and showers and thunderstorms are being provoked by the presence of that frontal boundary.
Gusty winds and fairly large hail (half dollar size) hail can be expected from these storms. Tornadoes are unlikely due to the nature of the storms and how linear they are.
