COOLER TEMPERATURES ALOFT APPEAR TO BE SOMEWHAT OFFSETTING THE
COOLER TEMPERATURES AT THE SURFACE. STRONGER NEARLY UNIDIRECTIONAL

SEGMENTS AND SPLITTING SUPERCELLS...AND ANTICYCLONIC MID LEVEL
ROTATION HAS RECENTLY BEEN OBSERVED ON RADAR IN A SUPERCELL LOCATED
IN CNTRL KLAMATH COUNTY. STORMS WILL REMAIN NEARLY STATIONARY OR
VERY SLOWLY PROGRESS TOWARDS THE WNW WITH TIME...WITH THE STRONGER
CORES PRODUCING LARGE HAIL AND/OR DMGG WINDS. FREQUENT LIGHTNING CAN
BE ANTICIPATED.
