*************************************************************  

WITH THE MID LVL TROF STILL HANGING BACK...A CYCLONIC LOOK TO THE 
SURFACE FLOW AND CONVECTIVE TEMPS WELL WITHIN REACH...KEEPING SOME 
CLOUDS IN FOR TODAY AND SOME FLURRIES IN THE FAR NW CONT TO LOOK 
LIKE A GOOD IDEA. THE SEASONABLY COLD AIR HAS ARRIVED...BUT THE 
ARCTIC SHOT COMES THROUGH AS THE UPPER JET FINALLY MOVES PAST US 
TONIGHT INTO TOMORROW. A FRESH WIND TODAY...THEN PERHAPS A BIT OF AN 
INCREASE IN THE FLOW TONIGHT INTO WED ON THE STRONG CAA. AMTSPHR 
DEFINITELY DRIES OUT GIVEN MODEL SOUNDINGS...AND SO CONFINED THE TUE 
NIGHT AND WED SHSN OR FLURRIES TO THE NWRN ZONES. ON TEMPS...LCL 
SCHEME AND CONTINUITY GENERALLY COME INTO AGREEMENT ON THE MAXES. 
DID THINK THE MET TEMPS WERE A BIT HIGH ON WED GIVEN THE H8 TEMPS. 
POSITION OF THE HIGH WED NIGHT SUGGESTS IT MIGHT BE TOUGH TO 
DECOUPLE AND RADIATE...AND PERHAPS SOME CI WILL BE MOVING IN THAT 
NIGHT TO BOOT...BUT STAYED ON THE LOW SIDE OF GUIDANCE WED NIGHT 
ANYWAY SINCE CLIMATOLOGY IN THE FOURTH PD MINS WOULD TEND TO PULL 
THEM UPWARD.  

FCST FROM THU ON LOOKED REASONABLE. MADE A LTL CHANGE TO WINDS ON 
FRI AND FRI EVENING FOR BETTER COORDINATION WITH SURROUNDING OFFICES.
