IF I DID NOT KNOW ANY BETTER I WOULD SWEAR WE ARE HEADED BACK INTO A WINTER PATTERN AND YET IT IS SUMMER. THE UPPER LEVEL PATTERN IS TRENDING BACK TOWARD SOME MAJOR AMPLIFICATION OF THE RIDGE IN THE WESTERN UNITED STATES. TYPICALLY WHEN THIS HAPPENS...A DEEP DIGGING TROUGH DEVELOPS OVER THE EASTERN UNITED STATES SENDING THE POLAR JET STREAM WELL SOUTH INTO THE SOUTHERN STATES. THE OTHER ISSUE AT HAND IS THE DEVELOPMENT OF THE UPPER LEVEL LOW OVERHEAD THAT REMAINS NEARLY STATIONARY THROUGH THE END OF THE FORECAST PERIOD.
AN UPPER LEVEL PATTERN LIKE THIS WILL CONTINUE TO ROTATE MOISTURE INTO THE FORECAST AREA AND KEEP A RELATIVELY COOL POOL OF AIR ALOFT OVER THE REGION. THIS WILL HELP TO SUPPORT THE DEVELOPMENT OF CONVECTION OVER THE REGION THROUGH MUCH OF THE EARLY PART OF THE FORECAST PERIOD. DAY TIME HEATING ALONG WITH THE UPPER LEVEL THERMAL PROFILE AND UPPER LEVEL POSITIVE VORTICITY MAXIMUMS ROTATING AROUND THE LOW WILL ALSO SUPPORT THE CONVECTION EXPECTED. SO WILL KEEP THE MENTION OF SHOWERS AND THUNDERSTORMS SATURDAY AND POSSIBLY INTO SUNDAY.
