Amar is correct, again. The
PDX discussion
posted a few house ago:<br>
LONG TERM...(FRIDAY THROUGH MONDAY) SPLIT-FLOW PATTERN WILL CONTINUE OVER THE EASTERN PACIFIC FRI. DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES LIKELY DURING THE WEEKEND AND INTO EARLY NEXT WEEK.<br><br>HAVE BACKED OFF ON PRECIP CHANCES THU NIGHT AND FRI. THE PAST COUPLE OF DAYS THE MEDIUM RANGE MODELS WERE GENERALLY ADVERTISING A SERIES OF SYSTEMS TO MOVE ACROSS THE AREA DURING THE MIDDLE AND LATTER PORTIONS OF THIS WEEK. NOW IT IS BACK TO A SPLIT PATTERN WITH THE MAIN ENERGY HEADING SOUTH ALONG THE CALIFORNIA COAST...AS HAS BEEN THE CASE ALL WINTER. SPAGHETTI CHARTS VALID FRI SHOW SOME UNCERTAINTY AS TO THE OVERALL PATTERN...BUT THE 00Z RUN AND OPERATIONAL GFS RUN FAIRLY SIMILAR WITH TROUGHINESS OVER CALIFORNIA. THE ECMWF AND UKMET ALSO INDICATING CLOSED UPPER LOW NEAR KSFO 00Z SAT. 00Z CANADIAN GIVES A DIFFERENT SOLUTION...WITH THE UPPER TROUGH FURTHER WEST...OUT AT 130W. LEFT CHANCE POPS FRI WITH SPLITTING SYSTEM AND POTENTIAL DEFORMATION ZONE OVER EXTREME SRN OREGON. SUSPECT THE FORECAST AREA WILL END UP DRY. SAT STARTS THE NEXT DRY SPELL AS 500 MB RIDGING BUILDS OVER THE PAC NW. SPAGHETTI CHARTS VALID 00Z SUN MUCH MORE IN TUNE...WITH JUST A COUPLE OUTLIER MEMBERS. UPPER LEVEL RIDGE TO HOLD FIRM SUN THRU THE MIDDLE OF NEXT WEEK. ECMWF ADVERTISES 1000-500 MB THICKNESS VALUES IN THE MID 550S SUN AND MON WITH 850 MB TEMPS AROUND 10C. THIS WOULD TRANSLATE TO AT LEAST LOWER TO MID 60S IN SEVERAL AREAS. THE 8-14 DAY PROGS DO NOT BODE WELL FOR TRYING TO MAKE UP THE CURRENT PRECIP DEFICIT. THE GFS MAINTAINS A REX BLOCK PATTERN THROUGH AT LEAST DAY 13 (MARCH 13). WEISHAAR
<br><br>I plan to do a lot of driving south this Spring.
