ZackH Posted May 8, 2011 Share Posted May 8, 2011 My team and I are heading towards the Valentine, NE area to most likely bunk for the evening while hopefully running into an isolated beauty on the way. At least we'll be in good position for tomorrow. Link to comment Share on other sites More sharing options...

THIS CONVECTION IS INDICATIVE OF THE VERY STEEP LAPSE RATES IN PLACE ACROSS THE CNTRL HIGH PLAINS WHERE SFC TEMPERATURES HAVE WARMED INTO THE MID 80S. LATEST THINKING IS SUSTAINED CONVERGENCE ALONG THE DRYLINE SHOULD PROVE FAVORABLE FOR ENCOURAGING SUSTAINED DEEP UPDRAFTS/TSTMS BY 00Z-02Z.

SEMIweather Posted May 8, 2011 Share Posted May 8, 2011 If I'm seeing things correctly out my window things are definitely getting going to my SW...going outside to get a better look. Link to comment Share on other sites More sharing options...
baroclinic_instability Posted May 8, 2011 Share Posted May 8, 2011 It looks like there is some sort of upper disturbance moving through aiding in the OK/TX development. Yeah no doubt about that. There is some impressive lee induced cirrus and a number of standing waves which would only be forced by an upper wave. Link to comment Share on other sites More sharing options...
thewxmann Posted May 8, 2011 Share Posted May 8, 2011 Maybe the smoke feeding into the area is aiding mass ascent and magically weakening the cap. Magic aside... the cap down in S OK/N TX has been more breakable than usual this year. Hence the drought relief in the DFW area. Have there been any studies on the influences of smoke/fire on convective initiation? Link to comment Share on other sites More sharing options...

Have there been any studies on the influences of smoke/fire on convective initiation? There was something in BAMS not too long ago about the effects of smoke on either convection or clouds and the effects on the microphysics. I don't remember what it was exactly though.

thewxmann Posted May 8, 2011 Share Posted May 8, 2011 LOL, just walked outside and couldn't believe my eyes... guess I'm off to Chickasha. With the high LCL's and CINH today, you might get some good structure to photograph. *crosses fingers* Link to comment Share on other sites More sharing options...
SEMIweather Posted May 8, 2011 Share Posted May 8, 2011 LOL, just walked outside and couldn't believe my eyes... guess I'm off to Chickasha. I'd go down that way if I had a car, gonna have to hope this can make it to Norman. Link to comment Share on other sites More sharing options...

L.B. LaForce Posted May 8, 2011 Share Posted May 8, 2011 movin on up Oh yes! was starting to doubt tomorrow, but this gives me hope. I will have to look into things a bit more in depth tonight. Link to comment Share on other sites More sharing options...
Hoosier Posted May 8, 2011 Share Posted May 8, 2011 Oh yes! was starting to doubt tomorrow, but this gives me hope. I will have to look into things a bit more in depth tonight. I've been liking the Monday potential for a couple days even if it is conditional on things being surface based. The directional shear is ridiculous...if there's such a thing as too much directional shear then tomorrow might be it. Link to comment Share on other sites More sharing options...
