More severe weather... They are using the Gulfstream IV hurricane hunter aircraft for some of these missions.
"The medium range guidance remains very persistent suggesting a deep cut off low develops in Northern Mexico, west of the Big Bend Region bringing copious heavy rains and severe weather chances across the S Plains and the Lower Mississippi during the January 24-26 period before ejecting NE affecting the EC. PW's near 1.7, which are rather impressive for January, will provide deep moisture and favorable upper level dynamics will set the stage for a severe weather event. The HPC has tasked WSR (Winter Storm Reconnaissance) for 22/00Z with additional missions possible from HI and AK. There does remain some uncertainty of potential phasing with the northern stream energy as the cyclone ejects NE."

More concern mounting for next weeks event. This was just posted by a meteorologist on a forum I visit:
"Just gave the final thumbs-up for tonights NOAA G-IV flight. A good case as it's a fairly major event and the models evolve it into some kind of east coast event after drenching Texas.
No flights for 1/23 but maybe one for 1/24 for a PacNW moderate/heavy precip event. "

What are we looking at Steve, more storms and tornados?

Yes. This event around the 24-26th might very well be a major severe weather event. The models are indicating a very strong area of low pressure forming in Texas that will bring large amounts of rain. One major concern is if this system phases with a branch of the jetstream and makes an even stronger system.

Temps will be falling behind the front. 40's are already entering northwest Georgia.
