SUBVORTEX STATUS MESSAGE DATE: 6/9/98 STATUS: GO...11 AM DEPARTURE EQUIPMENT STATUS: Mobile Mesonets: DOWS: operational UMASS Radar: down indefinitely Rockets: not operational Turtles: operational RALPH: operational NOAA P-3: 3 pm departure SYNOPSIS: Front is stalled from MAF to SPS to PNC. Latest RUC guidance suggests winds behind front will veer to easterly or southeasterly this afternoon. Moisture may be advected westward onto higher terrain producing CAPE anywhere from 500 J/kg to 4000 J/kg. Upper flow is very strong (perhaps too strong) at speeds at or above 100 kt at 10 km. 850 mb winds are progged to become SE over all of the High Plains by evening. DAY 1 FORECAST: See above. DAY 2 FORECAST: Upper flow is expected to become more meridional as heights rise on the Plains in association with digging trough in west. Deep-layer shear will probably not be sufficient for classic supercells along the dryline, however, the warm front may provide the better shear needed...although this may be too far north for us to target at this stage. DAY n FORECAST: Heights on the Plains are progged to fall slightly, with upper flow becoming less meridional once again. Operations are possible Thursday and/or Friday. MISCELLANEOUS: 1. Drivers are reminded that they should be watching the road and not the storm. 2. Some laptop disk drives are quickly running out of space. This is easy to correct by deleting unneeded application software. Team leaders should check disk space regularly on the laptop and let either J. Straka or D. Blanchard know if space is low.
