Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:33 am PDT on April 1, 2015


... Isolated thunderstorms... small hail... and locally heavy rain
possible again today...

An unsettled weather pattern will once again bring the potential
for a few heavy rain and small hail showers to develop across
southwest Washington and northwest Oregon today. The cool and
unstable environment may also allow some isolated thunderstorms
to develop this afternoon and evening.

Heavier showers yesterday produced localized issues with ponding
of water on roadways... as well as some localized accumulation of
small hail. Similar issues will probably occur today... but again
they will be fairly localized to stronger showers.

While most locations will just experience occasional showers...
drivers should be aware of the potential for rapidly changing
conditions especially this afternoon. Ponding of water in heavier
showers may cause fast moving vehicles to hydroplane. Small hail
may briefly accumulate on roadways... making roadways locally
slick.

Stay informed of the latest weather information by visiting our
web site at www.Weather.Gov/Portland... or by checking your
favorite media source or weather smart phone application.

NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND 
320 AM PDT WED APR  1 2015

.SYNOPSIS...COOL ONSHORE FLOW AND ANOTHER UPPER LEVEL TROUGH WILL
KEEP THE WEATHER UNSETTLED WITH NUMEROUS SHOWERS TODAY. ONCE AGAIN
HEAVIER SHOWERS MAY PRODUCE ISOLATED THUNDER AND SMALL HAIL. SHOWERS
WILL TAPER OFF TONIGHT AS A RIDGE OF HIGH PRESSURE BUILDS IN FOR A
DRIER DAY THURSDAY. ANOTHER FRONT IS EXPECTED FRIDAY FOLLOWED BY
ANOTHER ROUND OF SHOWERY WEATHER INTO NEXT WEEKEND. SNOW LEVELS WILL
BE BELOW THE CASCADE PASSES MUCH OF THE TIME THROUGH EARLY NEXT WEEK.
 
&&

.SHORT TERM...TODAY THROUGH FRIDAY...EXPECT ANOTHER DAY OF UNSETTLED
WEATHER ACROSS SOUTHWEST WASHINGTON AND NORTHWEST OREGON TODAY. COOL
ONSHORE FLOW CONTINUES THIS MORNING...WITH SEVERAL SHOWERS STILL
MOVING ACROSS THE FORECAST AREA DESPITE RELATIVELY COOLER SFC TEMPS.
CONVECTION HAS BEEN MOST ACTIVE OFF THE CENTRAL OREGON COAST...WHERE
A FEW LIGHTNING STRIKES WERE DETECTED JUST BEFORE A BATCH OF SHOWERS
MOVED ONSHORE JUST AFTER MIDNIGHT. THE FACT THAT SHOWER ACTIVITY
CONTINUES THIS MORNING IS A TESTAMENT TO THE COOL AIR ALOFT AND THE
RESULTING INSTABILITY IN PLAY FOR TODAY.

EXPECT SHOWERS TO CONTINUE THROUGH MIDDAY...WITH THE HEATING OF THE
DAY ONLY WORKING TO ENHANCE CONVECTION AS THE DAY PROGRESSES. NAM
BUFR SOUNDINGS CONTINUE TO SHOW RATHER STEEP LAPSE RATES UP TO
450-400 MB AND LITTLE TO NO CIN...WITH SFC PARCELS IN THE LOWER 50S
REACHING AN EQUILIBRIUM LEVEL OF 20-25 KFT. WITH ANY SUNBREAKS...OR
EVEN POSSIBLY WITHOUT THEM...SFC TEMPS SHOULD EASILY REACH THE LOWER
50S IN THE LOWLANDS. SO...OVERALL THE CONVECTIVE ENVIRONMENT TODAY
WILL BE VERY SIMILAR TO TUESDAY...PERHAPS SLIGHTLY LESS FAVORABLE DUE
TO SLIGHTLY MORE CLOUD COVER. 

MEANWHILE...AN UPPER LEVEL TROUGH CROSSING 130W IS AIMING STRAIGHT
FOR THE PAC NW COAST AND IS DUE TO ARRIVE THIS AFTERNOON. THIS WILL
ONLY SERVE TO ENHANCE LIFT AND PROMOTE DEEPER CONVECTION. LATEST HRRR
AND SPC SSEO RUNS SHOW THIS NICELY. THEREFORE WE FEEL CONFIDENT
ENOUGH TO CONVERT THE SLIGHT CHC THUNDER TO ISOLATED THUNDER THIS
AFTERNOON AND EVENING. WILL LIKELY SEE SOME POCKETS OF SMALL HAIL AND
LOCALLY HEAVY RAINFALL ONCE AGAIN. DIFFICULT TO TELL EXACTLY
WHERE...BUT THE TRAJECTORY OF THE UPPER TROUGH MAY FAVOR THE EAST
PORTLAND/VANCOUVER METRO FOR PERSISTENT TERRAIN-INDUCED CONVERGENCE
AND HEAVY RAINFALL RATES. WILL LIKELY ISSUE A SPECIAL WEATHER
STATEMENT TO MENTION THE POTENTIAL FOR ACCUMULATING SMALL HAIL AND
PONDING OF WATER DUE TO HEAVY SHOWERS AND ISOLATED THUNDERSTORMS. 

WHILE DIRECTIONAL SHEAR LOOKS SLIGHTLY BETTER THAN YESTERDAY...
MAGNITUDES DO NOT LOOK VERY IMPRESSIVE TO SUPPORT ROTATING UPDRAFTS.
THEREFORE INDIVIDUAL CELLS SHOULD BE SHORT-LIVED AND COLD CORE
FUNNELS ARE STILL UNLIKELY. HAIL SIZE SHOULD REMAIN WELL BELOW SEVERE
THRESHOLDS...BUT SMALL HAIL MAY STILL ACCUMULATE AND CAUSE LOCALIZED
TRAVEL ISSUES. 

AS FOR THE CASCADES...SNOWFALL AMOUNTS WERE A LITTLE MORE IMPRESSIVE
THAN EXPECTED YESTERDAY. TOTALS GENERALLY RANGED BETWEEN 4-7 INCHES
ABOVE 3500 FT...BUT TIMBERLINE AND SANTIAM PASS RECEIVED NEARLY A
FOOT FROM PERSISTENT SNOW FROM CONVECTIVE DEBRIS. WE DO NOT EXPECT
QUITE THIS MUCH SNOW TODAY...BUT IT IS NOT OUT OF THE QUESTION FOR A
COUPLE LOCATIONS RECEIVING MORE THAN 6 INCHES FROM CONVECTIVE DEBRIS
ONCE AGAIN. THIS SHOULD NOT BE WIDESPREAD...SO WILL OPT NOT TO ISSUE
A WINTER WX ADVISORY. SNOW LEVELS SHOULD REMAIN AROUND 3000 FT TODAY.

HIGH PRESSURE AT THE SURFACE AND ALOFT BUILD IN FROM THE SOUTHWEST
TONIGHT AND THURSDAY...CAPPING THE CONVECTION AND EVENTUALLY CAUSING
SHOWERS TO TAPER OFF. THERE COULD BE A COUPLE LINGERING SHOWERS INTO
THURSDAY...BUT THEY SHOULD BE MOSTLY CONFINED TO THE HIGHER TERRAIN.
WITHOUT MUCH LOW-LEVEL FLOW...LOW CLOUDS WILL PROBABLY HANG ON FOR A
GOOD PART OF THE DAY...KEEPING TEMPS MAINLY IN THE 50S FOR THE
LOWLANDS.

MODELS ARE TENDING TO FLATTEN THE SHORTWAVE RIDGE AHEAD OF THE
INCOMING FRONT ON FRIDAY...PERHAPS ALLOWING IT TO MOVE ONSHORE BY
FRIDAY MORNING AND SPREAD RAIN ACROSS MUCH OF THE FORECAST AREA BY
FRI EVENING. SNOW LEVELS WILL RISE A BIT AHEAD OF THE FRONT...
PERHAPS CLOSE TO CASCADE PASS LEVEL. HOWEVER COOLER AIR BEHIND THE
FRONT WILL CAUSE SNOW LEVELS TO DROP BACK DOWN TO AROUND 3000 FT IN
SHOWERS FRIDAY NIGHT. OVERALL...A FAIRLY TYPICAL EARLY SPRING
PATTERN...BUT MUCH MORE WINTER-LIKE THAN WHAT WE HAVE EXPERIENCED
MUCH OF THIS SEASON.  WEAGLE
 
.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...AFTER A COLD FRONT MOVES
ACROSS THE FORECAST AREA FRIDAY...EXPECT A RETURN TO COOL AND
UNSETTLED WEATHER FOR THE WEEKEND. MODELS ARE INCREASINGLY IN
AGREEMENT THAT A COOL UPPER LOW FROM THE GULF OF ALASKA WILL SETTLE
SOMEWHERE NEAR THE PAC NW COAST BY SUNDAY. STABILITY PROFILES THIS
WEEKEND LOOK SIMILAR TO YESTERDAY AND TODAY...PARTICULARLY SUNDAY.
BASED ON THIS WE ADDED A SLIGHT CHANCE OF THUNDER TO SUNDAY. MOST
MODELS CONTINUE TO DIG THE UPPER LOW INTO SW OREGON/NORTHERN CA EARLY
NEXT WEEK...WITH SHOWERS GRADUALLY ENDING MIDWEEK. KEPT POPS CLOSE TO
CLIMO MON/TUE...WITH TEMPS SLOWLY REBOUNDING TOWARD MIDWEEK.  WEAGLE 

&&

.AVIATION...AN UPPER LEVEL DISTURBANCE MOVING ONSHORE EARLY THIS
MORNING IS KEEPING SHOWERS AND ISOLATED COASTAL THUNDERSHOWERS
GOING...BUT EXPECT SHOWER ACTIVITY TO TAPER OFF FOR A WHILE AFTER
12Z. ANOTHER DISTURBANCE WILL INCREASE SHOWERS AGAIN LATER THIS
MORNING AND THIS AFTERNOON. SIMILAR TO YESTERDAY...EXPECT TO SEE SOME
SMALL HAIL AND ISOLATED THUNDER IS SOME OF THE BETTER SHOWERS.
MAINLY VFR CONDITIONS SHOULD PREVAIL THROUGH 12Z THU WITH BRIEF
PERIODS OF MVFR POSSIBLE IN THE HEAVIER SHOWERS. SHOWERS WILL
DIMINISH SIGNIFICANTLY LATER THIS EVENING INTO THU MORNING.

KPDX AND APPROACHES...SHOWERS TO CONTINUE TODAY. MUCH LIKE
YESTERDAY...EXPECT HEAVIER SHOWERS TO CONTAIN SMALL HAIL. THERE
WILL AGAIN BE A CHANCE FOR THUNDERSHOWERS LATER THIS MORNING AND
THIS AFTERNOON. CONDITIONS SHOULD BE MOSTLY VFR WITH BRIEF MVFR
POSSIBLE IN HEAVIER SHOWERS. SHOWERS TO TAPER OFF LATER THIS
EVENING. PYLE

&&

.MARINE...EXPECT WESTERLY WINDS LESS THAN 20 KT ON WED AND THU AS
HIGH PRES REMAINS OVER THE NE PAC. SEAS ARE ALSO EXPECTED TO REMAIN
STEADY AT 8 TO 9 FT DURING THIS TIME WITH A WESTERLY SWELL AT 12
OR 13 SECONDS. SHOWERS WILL CONTINUE THROUGH THIS EVENING...WITH
THE CONTINUED POSSIBILITY OF ISOLATED THUNDERSTORMS AND CONVECTIVE
WIND GUSTS UP TO AROUND 25 KT.

A FRONT IS MODELED TO MOVE INTO THE COASTAL WATERS FRI MORNING AND
PUSH INLAND FRI AFTERNOON. IT APPEARS THAT THE FRONT WILL BE
WEAKENING SIGNIFICANTLY AS IT NEARS SHORE...BUT IT MAY STILL
PRODUCE A PERIOD OF SMALL CRAFT ADVISORY WINDS. A LARGE UPPER
LEVEL LOW PRES SYSTEM WILL MOVE IN OVER THE WEEKEND AND THEN A
PROGRESSIVE WEATHER PATTERN IS EXPECTED INTO NEXT WEEK. FCST
DETAILS ARE SOMEWHAT UNCERTAIN GOING INTO THE WEEKEND...BUT THERE
DO NOT APPEAR TO BE ANY MAJOR WIND IMPACTS. HOWEVER...INCREASING
SWELL IS EXPECTED TO ARRIVE FRI AND INTO THE WEEKEND...LIKELY PUSHING
SEAS INTO 10 TO 12 FT RANGE. PYLE


&&

.PQR WATCHES/WARNINGS/ADVISORIES...
OR...NONE.
WA...NONE.
PZ...SMALL CRAFT ADVISORY FOR ROUGH COLUMBIA RIVER BAR UNTIL 8 AM  
     PDT THIS MORNING.

     SMALL CRAFT ADVISORY FOR ROUGH COLUMBIA RIVER BAR FROM 1 PM  
     THIS AFTERNOON TO 7 PM PDT THIS EVENING.
