March 18 Forecast Discussion

This is an image from the 18z GFS 24 hours out.
FORECAST DISCUSSION
Fairly weak low pressure over the Northern Rockies will once again bring a warm up to the Rocky Mountain areas. This low pressure will create windy conditions in the Nebraska area. This is not due to a warm air transport area but a small skirmish against warm and mild air masses.
High pressure in Canada will provide a Canadian cold air mass to move south into the Northeast region. Should current projections play out, that low pressure may be able to begin a battle of severe weather over the Plains into the Midwest.
Down in the south, high pressure will dominate the weather as it sits off the coast, providing for a warm and humid tomorrow. This will be assisted by another high pressure to the east of Florida.
When all is set and done, it is possible there could be a severe weather event in the Plains down south to the South Central regions of the US, back up possibly into the Midwest.
Another Forecast Discussion will be issued tomorrow.
