QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
359 PM EST TUE FEB 20 2018


PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID FEB 21/0000 UTC THRU FEB 24/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR

DAY 1

...LARGE SCALE HEAVY RAIN / FLOOD EVENT...

...EASTERN PLAINS / MID-UPPER MS VALLEY / GREAT LAKES / UPPER OHIO
VALLEY...

A SYNOPTIC PATTERN THAT SHOULD SPARK GREAT CONCERN OVER HEAVY
RAINFALL CONTINUES TO COME INTO PLACE...WITH LARGE SCALE
AMPLIFICATION OF THE WESTERN U.S. TROUGH...BLOCKED BY A 594 DM
RIDGE IN THE ATLANTIC...ALLOWING FOR PROLONGED ELONGATED MOISTURE
TRAJECTORIES EMANATING FROM THE CARIBBEAN BEFORE ENCOUNTERING A
SLOW MOVING FRONTAL ZONE IN THE MIDDLE OF THE NATION. PWAT VALUES
REMAIN WELL ABOVE NORMAL...WITH NEAR RECORD TO RECORD VALUES
STRETCHING FROM EAST TX ALL THE WAY INTO THE GREAT LAKES REGION.
SYNOPTICALLY HAVE SHORTWAVE ENERGY EJECTING INTO THE NORTHERN
PLAINS...HELPING INTENSIFY THE UPPER JET OVER THE AREA. INCREASED
ASCENT IN THE RIGHT ENTRANCE REGION OF THIS JET WILL HELP MORE
WELL DEFINE THE COLD FRONT OVER THE MIDDLE OF THE COUNTRY...AND
HELP PUSH IT EASTWARD WITH TIME. FROM THE MID MS VALLEY NORTHEAST
INTO THE OH VALLEY AND GREAT LAKES...THE FRONT WILL BE MORE
PROGRESSIVE IN NATURE HELPING CAP RAINFALL MAGNITUDES. STILL LOOKS
LIKE A BROAD SWATH OF MODERATE RAINFALL TOTALS THOUGH...AND SOME
WEAK INSTABILITY MAY TRY TO MOVE NORTH AHEAD OF THE EASTWARD
MOVING FRONT. THIS COULD RESULT IN SOME EMBEDDED CONVECTIVE
ELEMENTS AND LOCALLY HEAVY RATES INTO PORTIONS OF MO/IL/IN/MI INTO
THIS EVENING. GIVEN THE DEEP FROST DEPTHS AND INCREASINGLY
SATURATED CONDITIONS OVER THIS AREA...SHOULD THESE HIGHER RATES OF
BETWEEN 0.5"-1" IN AN HOUR MATERIALIZE...A FLASH FLOOD THREAT IS
POSSIBLE ON TOP OF THE ONGOING AREAL FLOODING.

THE FOCUS FOR HEAVIEST RAINFALL THROUGH THE DAY 1 PERIOD IS FROM
NORTHEAST TX INTO SOUTHEAST OK...AR AND NORTHERN LA. IT IS ACROSS
THIS AXIS WHERE THE COLD FRONT SHOULD BECOME NEARLY STATIONARY (OR
AT LEAST SLOW) THIS EVENING. CONTINUED MOISTURE TRANSPORT INTO
THIS BOUNDARY SUPPORTS TRAINING CONVECTION INTO TONIGHT. ON
WEDNESDAY AN ADDITIONAL WAVE APPROACHES FROM THE WEST ALONG WITH
THE LEFT EXIT REGION OF THE SUBTROPICAL JET. THIS SHOULD SUPPORT
AN INCREASE IN 850 MB MOISTURE TRANSPORT INTO THE
BOUNDARY...RESULTING IN INCREASING CONVECTIVE COVERAGE/INTENSITY
THROUGH THE DAY. CONVECTION SHOULD BE ABLE TO TAP INTO ENOUGH
INSTABILITY TO SUPPORT A CONTINUED EASTWARD PROGRESSION WITH TIME.
FOR THIS REASON FAVORED A BIT MORE OF THE PROGRESSIVE GUIDANCE
ACROSS TX/AR/LA ON WEDNESDAY. THIS INCLUDED THE 12Z RUNS OF THE
HRW ARW/ARW2/HRRR EXPERIMENTAL AND 0Z UKMET. ALL OF THESE
SOLUTIONS WERE A BIT MORE PROGRESSIVE THAN OUR PREVIOUS FORECAST
ACROSS THE LOWER MS VALLEY AND SEEMED TO FIT OUR EXPECTATIONS
BEST. THE DAY 2 (12Z WED-12Z THU) MODERATE RISK WILL THUS BE
SHIFTED A BIT SOUTHEAST TO MATCH THIS QPF AXIS. IT SHOULD BE NOTED
THAT SOME UNCERTAINTY WITH THIS AXIS ON WEDNESDAY REMAINS...WITH
SOME GUIDANCE EVEN MORE PROGRESSIVE THAN OUR NEW FORECAST...AND
OTHERS STILL SLOWER. THUS WILL NEED TO CONTINUE TO MONITOR TRENDS.
FOR NOW OUR 30 HOUR TOTALS (18Z TUE-0Z THU) SHOW 3-6" FROM
NORTHEAST TX INTO SOUTHEAST OK...CENTRAL AND WESTERN AR AND
NORTHERN LA...WITH A 4-7" MAX OVER NORTHEAST TX.


...ELSEWHERE...

LITTLE CHANGE TO THE FORECAST OUT WEST BENEATH THE DIGGING UPPER
TROUGH. THE SAME BLEND USED FOR THE EASTERN U.S. WAS APPLIED HERE
AS WELL. SOME OF THE HEAVIER SNOWFALL SHOULD OCCUR IN
WESTERN/CENTRAL COLORADO AND NORTHERN NEW MEXICO... SEE QPFHSD FOR
DETAILS.


DAYS 2/3...


...PACIFIC NORTHWEST/INTERMOUNTAIN WEST...

SHORT WAVE ENERGY DROPPING INTO A REFORMING LONG WAVE TROUGH OVER
THE WESTERN UNITED STATES PROVIDES SUFFICIENT LIFT FOR QPF ACROSS
THE PACIFIC NORTHWEST DURING DAY 2. MEANWHILE...SHORT WAVE ENERGY
EJECTED FROM THE BASE OF THE REFORMING TROUGH PROVIDES LIFT OVER
AN ARCTIC FRONT FOR QPF ACROSS THE GREAT BASIN AND SOUTHERN
ROCKIES.

DURING DAY 3...ADDITIONAL SHORT WAVE ENERGY DIVES INTO THE BASE OF
THE LONG WAVE TROUGH...PROVIDING LIFT FOR QPF OVER THE SIERRA
NEVADA RANGE IN CA...AS WELL AS THE GREAT BASIN...SOUTHERN ROCKIES
AND SOUTHWEST.

THERE IS GENERALLY GOOD MODEL AGREEMENT WITH RESPECT TO THE TIMING
OF THE SHORT WAVE ENERGY DIVING INTO THE INTERMOUNTAIN
REGION...ESPECIALLY ON DAY 2.  BUT THERE CONTINUES TO BE
INCREASING SPREAD IN THE MODEL SOLUTIONS CONCERNING HOW THE LONG
WAVE TROUGH REFORMS DURING DAY 3. IN AN ATTEMPT TO MITIGATE SOME
OF THE DIFFERENCES...THE WPC QPF WAS BASED ON A BLEND OF THE 12Z
ECMWF/GFS...WITH MORE EMPHASIS PUT ON THE GFS CONSIDERING HOW ITS
PRECIP FIELDS WERE A BETTER FIT TO THE TERRAIN OF THE COASTAL
RANGES AND TO THE UINTAS AND SAN JUANS ON DAY 3 AS WELL AS TO THE
WAY THEY FIT DYNAMICS.

...CENTRAL PLAINS INTO THE UPPER MS VALLEY/SOUTHERN LAKES TO THE
EAST COAST...

PART ONE OF SEVERAL ROUNDS OF HEAVY TO EXCESSIVE RAINFALL SHOULD
BE ON GOING AT THE START OF THE DAY 2 FORECAST PERIOD AT
22/0Z...WEDNESDAY EVENING.  MODEL AGREEMENT REMAINS GOOD EARLY IN
THE PERIOD IN TERMS OF WHERE THE AXIS OF ANOMALOUS PRECIPITABLE
WATER VALUES SET UP AND THE BEST CHANCES FOR PRECIPITATION MAINLY
FROM THE CENTRAL PLAINS TO THE GREAT LAKES.  BY THE END OF DAY
2...THOUGH...AN IMPORTANT DIFFERENCE OPENS UP BETWEEN THE GFS
ATTEMPTING TO MOVE ITS SURFACE FRONT FASTER TO THE SOUTHEAST THAN
DID THE NAM/ECMWF/UKMET. GIVEN SPRAWLING HIGH PRESSURE TO ITS
NORTH AND A SECOND AREA OF HIGH PRESSURE PRETTY WELL LOCKED IN
OVER THE WESTERN NORTH ATLANTIC OCEAN...THERE DOES NOT SEEM TO BE
A LOT OF ROOM FOR TOO MUCH SOUTHWARD ADVANCEMENT OVER THE
APPALACHIANS AND EASTERN TN VALLEY.  WPC KEPT CLOSER TO THE
NAM/ECMWF AND UKMET.  OVERALL...THOUGH...THE OVERALL IDEA THAT
PRECIPITATION ASSOCIATED WITH THIS WAVE WILL BECOME LESS INTENSE
AS THE SYSTEM PROGRESSES EASTWARD.

ON THE NORTHERN SIDE OF THIS SYSTEM...THE MODELS ARE ADVERTISING A
SECOND AREA OF LIGHT PRECIPITATION DEVELOPING OVER THE UPPER MS
VALLEY IN RESPONSE TO ISENTROPIC UPGLIDE THAT DEVELOPS IN THE WAKE
OF DEPARTING HIGH PRESSURE.  THERE WAS SOME CONVERGENCE IN THE
MODEL SOLNS AND A GENERAL MODEL BLEND WAS EMPLOYED HERE.


...SOUTHERN PLAINS/LOWER AND MID MS VALLEY INTO THE WESTERN OH/TN
VALLEY...

ROUND 2 OF HEAVY RAINFALL SHOULD DEVELOP LATE EARLY ON DAY 3 OVER
PORTIONS OF THE SOUTHERN PLAINS AS LOW LEVEL FLOW ACCELERATES AND
RIDES UP AND OVER THE SYNOPTIC BOUNDARY LEFT BEHIND BY THE FIRST
SYSTEM.  THE MODEL QPF WAS RATHER CHAOTIC EARLY ON DAY 3 AS THE
ATMOSPHERE GOES THROUGH A TRANSITION...BUT THE MODELS THEN
CONVERGE ON THE IDEA OF INCREASING COVERAGE OF RAINFALL AND
INCREASING RAINFALL RATES OVER PARTS OF TX/OK/AR ON DURING THE
LATTER HALF OF DAY 3.  WE TENDED TO SIDE WITH THE WETTER CAMP OF
MODEL GUIDANCE SINCE PRECIPITABLE WATER ANOMALIES ARE STILL
FORECAST TO RUN ROUGHLY 2.5 STANDARDIZED ANOMALIES ABOVE
CLIMATOLOGY. 

BASED ON A SHIFT SOUTH AND EASTWARD IN QPF DURING THE LATTER PART
OF THE DAY 2 OUTLOOK...NUDGED THE SOUTHERN AND EASTERN BOUNDARY OF
THE MODERATE RISK SOUTHWARD. 

WENT THROUGH ANOTHER ITERATION ABOUT WHETHER OR NOT TO UPGRADE THE
SLIGHT RISK AREA IN THE CURRENT DAY 3 EXCESSIVE RAINFALL OUTLOOK. 
OPTED TO KEEP THE SLIGHT RISK IN PLACE AND NOT UPGRADE TO A
MODERATE...PRIMARILY SINCE THE HEAVIEST RAINFALL ON DAY 3 FALLS
AFTER THE END OF THE DAY 3 EXCESSIVE RAINFALL OUTLOOK
/SPECIFICALLY IN THE 23/12Z TO 24/00Z PERIOD/.  IT IS ASSUMED THAT
THIS SECOND BOUT OF MODERATE TO HEAVY RAINFALL WILL NEED TO BE
ACCOUNTED FOR IN SUBSEQUENT OUTLOOKS.
