Severe Weather Outbreak 02/16-02/17

Forgot the important stuff.

 Medium-range guidance is in good agreement that a strong shortwave
   trough will drop southward from the Pacific Northwest into southern
   CA on D4/Monday and D5/Tuesday. This shortwave is then expected to
   eject eastward across the Southwest/northern Mexico into the
   southern Plains on D6/Wednesday before continuing northeastward
   across the Mid MS Valley and Lower/Middle OH Valley on D7/Thursday. 

   Very strong mid-level flow will accompany the shortwave, with strong
   low-level flow anticipated throughout the warm sector ahead of the
   shortwave as well. This strong low-level flow will contribute to
   robust moisture advection, with upper 50s dewpoints into southern OK
   and low 60s dewpoints through much of central TX by early
   D6/Wednesday evening. This moisture advection will continue on
   D7/Thursday, with upper 50s dewpoints likely reaching into the
   middle OH Valley by D7/Thursday evening.

   The combination of lift, strong vertical shear, low-level moisture,
   and buoyancy will likely result in severe thunderstorms. Current
   guidance indicates the most probable location for severe storms on
   D6/Wednesday is from central TX northeastward across eastern OK,
   central/western AR, and northwest LA. For D7/Thursday, the severe
   risk extends from the Lower MS Valley through the Mid-South into the
   Lower OH Valley.

Doesn’t look like a major outbreak. Thursday probably has the most potential of the two days. 
 

Timing has slowed down, trending threat areas farther west. Wednesday looks like mainly a nocturnal threat at this juncture across Texas and possibly parts of Oklahoma. Thursday could be more potent across the lower Mississippi Valley.

Looks like we got our first severe thunderstorm warning over Odessa, with a risk for 70 mph wind gusts.  Dew points are only in the 30s and 40s there, but there is still a little instability present.

Very strong wind fields - 00z MAF (Midland-Odessa) sounding sampled 107 knots of 0-6 km shear. Impressive wind profiles will drive the severe threat through Thursday night.

I guess this isn't getting a lot of discussion, but may very well be a dangerous tornado outbreak

That's what I'm leaning more towards. SB & MLCAPE are solid, condensation level is basically on the ground, and both shear & SRH are pretty high.

I will say though it's lining a bit much this early in the game and maybe pushing too far east of where the best dynamics are

Second tornado warning on this cell, first was (inexplicably in my opinion) allowed to expire about 20 minutes ago.

There is too much throwing out the word outbreak with limited data to back it up. Again today was not an outbreak by any means not even close. If the hype is all that is put out you will see people not believing it when the data really supports it.  Remember part of the issue that was looked at after Joplin was the number of tornado warnings issued by NWS Springfield that were not backed up by what really was occuring.
