Posted: Tue Nov 03, 2009 12:43 pmCURRENT PROBLEM:
LONG WAVE PATTERN AT THE MOMENT IS STILL HIGHLIGHTED BY A LARGE SCALE UPPER RIDGE AT THE DATELINE WITH A MINOR LONG WAVE TROF NORTH OF HAWAII. THE UPPER JET IS PRETTY ZONAL BY THE WEEKEND WITH SHORT WAVE ENERGY SPLITTING DOWN STREAM OF THE UPPER HIGH AS IT WEAKENS INTO THE DOWNSTREAM UPPER RIDGE OVER THE FAR WEST US. THE NOSE OF A 170 KNOT UPPER JET WILL BE APPROACHING PORTLAND THURSDAY NIGHT...AND INTO OREGON FRIDAY...WELL TO THE NORTH OF CENTRAL CA.....AND EVEN THE TAHOE AREA TO DO MUCH GOOD. UNTIL THE DATELINE RIDGE REDEVELOPS FURTHER TO THE EAST OR WEST....OUR PATTERN WILL REMAIN DRIER THEN NORMAL.
SPECULATION:
I STILL LIKE TO USE THE INTER-SEASONAL TOOL (PHASE SPACE) ASSOCIATED WITH MJO FOR THE PROSPECTS OF CHANGE. AS INDICATED YESTERDAY, THE MJO IS TRACKING EAST AT A PRETTY GOOD CLIP NOW. AT THIS PACE, WE SHOULD "BEGIN TO SEE IN THE MODELS" RETROGRESSION IN THE PACIFIC PATTERN BY THIS WEEKEND AND REALIZE POSSIBLY A COLDER INSIDE SLIDER PATTERN LATER THAT WEEK. BEYOND THAT, BEST GUESS, A LONG WAVE TROF SETS UP "ABOUT" OR DURING THE TIME AFTER THE 15TH. THAT IS, IF THE INTER-SEASONAL OSCILLATION GETS INTO PHASE SPACE 4/5 BY THEN.
IT WILL BE INTERESTING TO SEE IF A PATTERN CHANGE COINCIDES WITH THIS EASTWARD SHIFT OF MJO. HOWEVER, IT IS UNDERSTOOD THAT THE RESULTS WOULD STILL NOT BE CONCLUSIVE...JUST INTERESTING TO NOTE.

At least it'll be cold enough for some productive snowmaking.
