Monitoring models (GFS) for possible severe weather Christmas weekend in the south

Computer models are continuing to trend towards a possible impressive Christmas Eve and Christmas Day low pressure storm system to affect the south and southeast United States. Santa might be chasing down supercells and working around a likely strong squall line at some point of his journey.

The southeast looks to take the full brunt of the bad weather starting on Christmas Eve and working all the way into Christmas night. Timing of this system can still change some with it still being out six days away, but it does look like something is coming together for a nasty holiday weekend.

The subtropical jet stream continues to be very active and was expected with the development of El Nino earlier this year. During El Nino winters, the subtropical jet stream shifts further south bringing more low pressure systems and stronger upper level winds to the south and Florida. This all helps to produce above rainfall for the winter dry months and more severe weather.

As I write this, it’s raining hard outside as the easterly flow off the ocean is helping to produce some moderate showers in the onshore flow. Wish I could crawl back into bed until the rain stops! :-P

So, as the weekend nears, I’ll be closely monitoring the model trends and area forecast discussions for a possible Christmas chase weekend in the south…. Stay tuned!
