March 18th SE Weather Edition

Models are starting to come into better agreement with the next system across the Southeast. 00z GFS is slightly faster then the 00z ECM with bringing rainfall into the southeast. GFS brings rainfall into the Southeast between Sunday 6 Z and 12 Z while the ECM does not start to bring precipitation into the SE till between 12 Z and 18 Z with the more steady precipitation over the areas by the overnight period on sunday.
Another major difference with the ECM tonight is that it is not as cold as it was at 12 Z behind the cold front. So with less of a difference with the air mass ..instability might not be as strong and this could cut down on the severe weather potential. However..this is something that we will continue to keep an eye on as we are still a few days out. ECM moves the rainfall out of the southeast by late monday evening..
It appears that with the flow being southwest out ahead of the front that temperatures ahead of the front will range anywhere from 60-65 across the western areas to 65-75 across the eastern areas.
Real Weather Services at this point and time is thinking that this will be an all rain event with temperatures so warm out ahead of the front and behind the front the temperatures are not really cold enough to support anything frozen.
Its possible that the higher elevations may still see some flakes flying in the sky but Real Weather Services does not anticipate any accumulations...
