SYNOPSIS:

Dying MCS in central and eastern TX.  Upper flow and vertical shear are
weaker than yesterday.  Supercells anywhere on the southern High Plains 
are not anticipated today as upper level geopotential gradient continues 
to weaken. 


DAY 1 FORECAST:

See above.  Supercells are not expected in the Southern Plains.


DAY 2 FORECAST:

Eta forecasts a dryline to be in western OK during afternoon/evening.  
Deep-layer shear is expected to be too weak to support supercells for any 
convection that may be initiated along the dryline.


DAY n FORECAST:

MRF and NOGAPS are almost identical with the MRF being slightly slower 
than the NOGAPS by about 12 hours.  NOGAPS brings 50-70 kt 200 mb flow 
back to the High Plains of New Mexico and W TX by Friday evening.  MRF 
brings 50 kt flow into the High Plains by Friday evening, with 50-70 kt 
brought in by Saturday morning.  By Saturday evening, both models bring a 
strong jet into the central Plains, and several days of fast upper 
tropospheric flow may persist beyond Saturday.  

Operations are anticipated for Friday and Saturday, and possibly into 
early next week.  A multi-day road trip may be necessary.


MISCELLANEOUS:

1. There is a slight chance we may need to depart tomorrow (Thursday) 
afternoon or early Fri morning depending on how far north we need to be 
on the High Plains.
