The Convective Initiation group compared simulated ABI and current GOES water vapor imagery to examine the dry line over Texas and western Oklahoma and to evaluate the performance of the NSSL-WRF through early morning. The presence of lee waves downstream of the mountains in extreme southwest Texas was noted on the imagery. Overall, the NSSL-WRF accurately depicted most of the large-scale features, with the usual differences in the locations of individual cloud and convective features. The simulated imagery indicates that convective initiation will occur later in the day along the dry line from south-central Kansas to north Texas. The dry line was also evident in the mid-level (band 9) water vapor imagery prior to convective initiation.
