No posts on what looks to be an cute little severe event this afternoon on the llano estacado?  CAMs are pretty enthusiastic about generating some supercells that should be surface-based for at least a couple of hours until they outrun the best surface instability and evolve into elevated clusters.  Not like there's going to be a huge tornado outbreak or anything, but its better than nothing . . .

It's definitely been a pretty boring stretch of weather the last month or so (or more?). At least this week there's been slight chances of afternoon thunderstorms, but I can't seem to cash in on one. NWS has a 50% chance for today so we'll see, I'm not holding my breath.

Other than a PDS tornado watch earlier this year (that didn't pan out), and a soggy February, I've been pretty underwhelmed by this spring.

DFW sounding showed some pretty good lapse rates this morning

and 3km nam really ramps up the surface instability later on. Windfields are a bit of a mess, though strong aloft.  The storm complex in OK is through Ardmore at present and hasn't weakened too much just yet... If it can keep pushing past the Red River I think there's a decent shot SPC ups the metroplex to slight risk later on.  Forcing is pretty weak without that OFB...

Mesoscale Discussion 0516
   NWS Storm Prediction Center Norman OK
   1121 AM CDT Fri May 25 2018

   Areas affected...North Texas

   Concerning...Severe potential...Watch unlikely 

   Valid 251621Z - 251845Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A few strong wind gusts are possible as storms move south
   across the area today, but severe weather is not expected.

   DISCUSSION...A complex of storms with southward-surging outflow is
   currently crossing the Red River into TX. These storms are not
   severe as of 16Z, but have produced 30-40 mph wind gusts. Some
   increase in intensity is possible this afternoon.

   The 12Z FWD sounding shows around 3000 J/kg MUCAPE when modified for
   current surface conditions. Although shear profiles are weak, storms
   are expected to forward-propagate and maintain and/or increase
   slightly. An isolated severe wind gust cannot be ruled out, but
   severe coverage is not expected to warrant a watch at this time. In
   addition to wind, marginal hail is possible as well given cool
   temperatures aloft and substantial instability.

Looks like the city had 0.5-1.0 inches of rain today, with areas west of town reporting up to 3 inches and a couple confirmed tornado. Lots of hail and thunder around too. Rained so hard it was actually fell into the upper 50s around 3 pm, which is an amazing outcome for June.

thunderstorm complex held together better than expected this morning and dropped a fair amount of precip across the metroplex, particularly east of Dallas (Garland/Mesquite) where they're pushing 2-3".  Parts of Ft Worth did ok too, and along the I35E corridor.

Just a few sprinkles so far IMBY. Clouds for most of the day from the MCS that fell apart to the west did a decent job of holding down temps. There's a few severe thunderstorms in the area but they're mostly just to my south. If I'm lucky I might get grazed by a shower and pick up 0.05" or so. I'm still holding out hope for more development overnight into tomorrow. I guess I better start my rain dance.
