NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND 
220 PM PDT SUN MAR 29 2015

.SYNOPSIS...MILD AND MOSTLY DRY WEATHER WILL CONTINUE THROUGH MON AS 
A FLAT UPPER LEVEL RIDGE REMAINS OVER THE PAC NW. A COLD FRONT WILL 
PUSH ACROSS THE REGION MONDAY EVENING USHERING IN A MUCH COOLER AND 
MORE SEASONABLE AIR MASS ALONG WITH SHOWERS AND LOWER SNOW LEVELS 
THAT WILL LAST THROUGH THE END OF THE WEEK.
 
&&

.SHORT TERM...LIGHT RAIN SPREAD DOWN TO THE S WA COAST THIS 
AFTERNOON...DRIVEN BY WEAK ISENTROPIC LIFT DOWN NEAR 290K ISENTROPE. 
ECWMF INDICATES THIS AREA TO LIFT N OVERNIGHT...WHILE GFS HANGS ON 
TO SOME WEAK LIFTING INTO MON MORNING SO WILL NEED TO HANG ON TO 
SOME LOW POPS THERE INTO MON MORNING. ELSEWHERE EXPECT DRY WEATHER 
TO CONTINUE THROUGH MON AS THE FLAT UPPER RIDGE HOLDS. GOOD 
RADIATIONAL CONDITIONS TONIGHT OVER MUCH OF THE SE PART OF THE ARE 
WILL ALLOW TEMPS TO DIP DOWN CLOSE TO NORMAL...WITH ABOVE NORMAL 
AFTERNOON TEMPS RETURNING MON. 

MODELS REMAIN SIMILAR WITH THE NEXT SYSTEM ARRIVING MON NIGHT... 
PUSHING A COLD FRONT INLAND DURING THE EVENING. TIME HEIGHT CROSS 
SECTIONS SHOW STRONG LIFT AND MOISTURE BELOW 500 MB TO JUSTIFY 
CATEGORICAL POPS FOR MON NIGHT. THIS USHERS IN A COOLER UNSTABLE AIR 
MASS FOR TUE AND CONTINUING INTO WED AS A COLD UPPER TROUGH MOVES 
ACROSS. WITH H8 TEMPS EXPECTED TO DROP A FEW DEGREES BELOW ZERO C 
SURFACE HIGH TUE AND WED ARE LIKELY TO COME BACK DOWN CLOSER TO 
NORMAL. MODEL SOUNDINGS INDICATING GOOD INSTABILITY TUE...AT LEAST 
BY PACNW STANDARDS...WITH GFS AND NAM CAPE VALUES MAXING OUT IN 
TRIPLE DIGITS. WITH THE TOP OF THE UNSTABLE LAYER APPROACHING 20K FT 
IN ADDITION TO SHOWERS LIKELY WILL NEED TO INCLUDE A CHANCE FOR 
THUNDER IN THE AFTERNOON AND EVENING AS THE COLD TROUGH ALOFT MOVES 
ACROSS. ANOTHER SHORTWAVE WITH A COLD POOL ALOFT...H5 TEMPS AGAIN 
DOWN NEAR -32...WILL ADD IN A SLIGHT CHANCE FOR THUNDER AGAIN WED. 
 
.LONG TERM...THE COLD UPPER TROUGH OF MIDWEEK IS DEPICTED BY MODELS 
EXITING THE REGION THU...WITH A WEAK RIDGE MOVING ACROSS LATE THU 
AND FRI. GFS AND ECMWF BOTH INDICATE SOME LIGHT RESIDUAL 
PRECIPITATION THU...BUT WITH UPPER DYNAMICS SHIFTED E AND MAINLY 
JUST SOME SHALLOW LOW LEVEL MOISTURE LEFT WILL CUT BACK ON POPS A 
BIT FOR THU. 12Z MODEL RUNS ALSO A BIT SLOWER IN DIGGING IN THE NEXT 
TROUGH AND COLD FRONT LATE FRI SO WILL BACK OFF ON POPS ACROSS THE S 
PART OF THE FORECAST AREA FRI. OVER THE WEEKEND MODELS NOW TENDING 
TO DIG THE NEXT TROUGH DOWN OFF THE COAST...CLOSE ENOUGH TO PUSH A 
FRONT THROUGH SAT AND KEEP THE REGION IN A COOL UNSTABLE AIR MASS 
FOR SUN.
&&

.AVIATION...VFR CONDITIONS EXPECTED TO CONTINUE THROUGH TODAY AND
TONIGHT WITH VARIABLE HIGH CLOUDS. VFR CIGS ABOVE 6000 FT CONTINUE
ALONG THE NORTH COAST NEAR KAST...BUT MAY GRADUALLY LOWER INTO
LOWER VFR OR PERHAPS HIGHER MVFR AFT 03Z. A POSSIBILITY EXISTS
THAT THESE WILL MAKE THEIR WAY FURTHER SOUTH TOWARDS KONP AFT
07Z...BUT CONFIDENCE IS LOWER FOR THIS. ELSEWHERE...VFR LIKELY
PERSISTS WITH VARIABLE HIGH CLOUDS. MAY AGAIN SEE SHALLOW FOG OR
STRATUS DEVELOP LATE TONIGHT/EARLY MON PARTICULARLY IN THE SOUTH
VALLEY AND IN MORE FOG-PRONE LOCATIONS. INCREASING AND LOWERING
MID/HIGH CLOUDS INTO THE COAST AFT 09Z AND INTERIOR AFT 12-18Z
MON.

KPDX AND APPROACHES...VFR CONDITIONS CONTINUE TODAY AND TONIGHT
WITH A BROKEN HIGH CLOUD DECK. INCREASING AND LOWERING MID/HIGH
CLOUDS LATE AFT 15Z MON BUT REMAINING VFR THROUGH NEXT 24 HOURS.
CULLEN

&&

.MARINE...SOUTHERLY WINDS CONTINUE THIS AFTERNOON AND HAVE
REMAINED A LITTLE GUSTY...AROUND 20 KT...PARTICULARLY IN THE
NORTHERN ZONES AS ANTICIPATED IN THE MORNING UPDATE. WINDS WILL
MAINTAIN OR EASE SLIGHTLY EARLY TONIGHT... BUT THEN AGAIN INCREASE
ON MONDAY AHEAD OF THE NEXT FRONTAL SYSTEM THAT WILL CROSS THE
WATERS TOMORROW. SMALL CRAFT ADVISORY FOR WINDS WILL BEGIN AT 5 AM
IN THE NORTH WHERE WINDS WILL INCREASE TO 20 KT. EXPECT WINDS TO
PEAK AROUND 25 KT WITH GUSTS TO 30 KT DURING THE LATE AFTERNOON
AND EVENING HOURS. MODELS ARE IN GOOD AGREEMENT THAT STRONGER
WINDS WILL NOT ARRIVE IN THE SOUTHERN WATERS UNTIL THE AFTERNOON
SO THE ADVISORY BEGINS AT 2 PM FOR THE CENTRAL OREGON WATERS.
WINDS SHOULD EASE BY 11 PM ACROSS ALL WATERS.

MEANWHILE SEAS REMAIN AROUND 10 TO 11 FT IN THE NORTHERN ZONES.
SPARSE OBSERVATIONS MAKE IT A BIT TOUGHER TO DISCERN IF SEAS HAVE
DROPPED OFF A BIT IN THE SOUTH...SO ELECTED TO MAINTAIN THE
ADVISORY FOR HAZARDOUS SEAS AS IS...THROUGH 5 AM. THIS WILL LIKELY
NEED TO BE EXTENDED IN THE NORTH...BUT SUSPECT ENOUGH OF A RESPITE
IN SEAS WILL OCCUR IN THE SOUTH TO LET IT EXPIRE. HOWEVER...SEAS
AGAIN WILL BUILD TO NEAR 12 FT ACROSS ALL WATERS BEHIND THE FRONT
AND INTO TUESDAY. CULLEN
