500 MB TROFF MOVES ACROSS ALASKA OVER THE NEXT 60 HRS. THIS PUSHES A
COLD FRONT OVER NORTHERN ALASKA WHICH IN TURN PUSHES THE THERMAL
TROFF FROM CENTRAL AK OVER SOUTHCENTRAL AND SOUTHWEST AK.  WITH 850
MB TEMPS WARMING AND COLDER AIR ALOFT WITH THE UPPER WAVE THINGS ARE
SETTING UP TO BE RATHER CONVECTIVE THE NEXT FEW DAYS. FIRST SHORT
WAVE WILL MOVE ACROSS OUR AREA WEDNESDAY MORNING TO TRIGGER
THUNDERSTORM DEVELOPMENT EARLY IN THE DAY. THE THERMAL TROFF DEVELOPS
IN THE AFTERNOON TO KEEP IT GOING INTO THE EVENING HOURS. THE NEXT
WAVE CROSSES SOUTHCENTRAL THURSDAY AFTERNOON BUT MAY HAVE TOO MUCH
CLOUD COVER TO REALLY SET OFF THE THUNDERSTORMS.  BY THIS TIME THE
APPROACHING LOW OUT NEAR ADAK HAS PUSHED THE COLDER AIR BACK TO THE
NORTH AND THE PATTERN MOVES ON.

OUT IN THE BERING THE SUMMER PATTERN OF LOW CLOUDS AND LIGHT PRECIP
CONTINUES UNDER THE NORTHERLY FLOW UNTIL THE APPROACHING NORTH
PACIFIC LOW TURNS THE WINDS TO THE SOUTHWEST MID WEEK.
