Morning MCS over the southeastern Texas panhandle has resulted in a north-westward propagating outflow boundary.  This boundary has merged with a loosely defined dryline in northern parts of the CWA, with the dryline then extending further to the south.  More elevated values of GOES CI (30-60%) has focused very well along these boundaries.  An area of 75% probability was indicated at 1937 UTC.  By 1956, a weak echo was apparent in the AMA radar reflectivity.  By 2008 UTC, the intensity had increased to 50-60 dBz.
