QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
539 AM EDT TUE MAY 22 2012
FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID MAY 22/1200 UTC THRU MAY 25/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR
DAY 1...
06Z UPDATE...
ONLY MINOR ADJUSTMENTS WERE MADE TO PRELIM GUIDANCE BASED ON
INCLUSION OF 00Z ECMWF AS WELL AS LATEST SATL/RADAR TRENDS.
...EASTERN U.S...
WEAK UPPER TROF OVER THE MID ATLC REGION IS EXPECTED TO SHEAR NEWD
DAY 1 WHILE SECONDARY TROF DROPS SEWD TOWARD THE SRN APLCNS TUES
NIGHT/WED MRNG. PCPN PATRN OVER MUCH OF THE EAST WILL LIKELY BE
DOMINATED MORE BY MESOSCALE PROCESSES GIVEN WEAK FORCING ALOFT AND
WEAKENING SFC COLD FRONT EDGING EWD THRU THE APLCNS. THE ONLY
ORGANIZED WAVE OF NOTE IS WITH SYSTEM LIFTING NEWD EARLY IN THE PD
ACRS COASTAL SECTIONS OF THE NE WHERE WEAK ONSHORE FLOW IS
EXPECTED TO BRUSH PARTS OF THE NE..ESPECIALLY DOWNEAST MAINE.
OTHERWISE..WITH MESOSCALE FEATURES DOMINATING MUCH OF THE FORCING
HERE..HAVE TAKEN AN ENSEMBLE APCH TO QPF ACRS MUCH OF THE
EAST..WITH POCKETS OF SOMEWHAT HIER ORGANIZED RAINS WITH HEIGHT
FALLS DROPPING INTO THE SRN APLCNS..AS WELL AS WEAK CONVERGENCE LO
LEVEL FLOW EARLY IN THE PD ACRS PARTS OF MDT NWD INTO CNTL PA/SRN
NY.
...EXTREME SRN FL...
PROXIMITY TO STG UPR JET DYNAMICS AS WELL AS DEEP MSTR NEAR AND
SOUTH OF THE KEYS SHOUDL RESULT IN THE DVLPMNT OF SHWRS OVR THE
EXTREME SRN PORTION OF THE PENINSULA WITH PERHAPS SOME 1 INCH OR
GREATER AMOUNTS OVER EXTREME SRN FL.
...PAC NW TO THE NRN PLAINS/UPR MS VALLEY...
STG UPR JET PUNCHING ACRS THE PAC NW/NRN INTERMOUNTAIN REGION WILL
PUSH AN AREA OF HEIGHT FALLS RAPIDLY ACRS THE PAC NW INTO THE NRN
PLAINS BRINGING WIDESPREAD SHWRS ACROSS THIS REGION TUES. LOW
PRES IS EXPECTED TO ORGANIZE OVER THE NRN PLAINS AND LIFT NEWD
INTO SCNTL CANADA WED MRNG AND AS IT DOES...STRENGTHENING LOW
LEVEL JET AHEAD OF THE LOW AND ACCOMPANYING WAA PATRN/MSTR ADV
WILL LEAD TO INCREASED CONVECTIVE POTNL OVER PARTS OF ERN ND INTO
WRN MN TUES NIGHT. MODELS ACTUALLY SHOW REASONABLY GOOD
AGREEMENT OF THE LARGER SCALE PATRN WITH THE EXCEPTION OF MINOR
TIMING DIFFERENCES OF EMBDD WEAK IMPULSES..AND HENCE OPTED TO
BLEND THE QPFS MOST AREAS..WITH AN EMPHASIS ON WLY FACING UPSLOPE
AREAS IN THE WEST.
DAYS 2 AND 3...
...CENTRAL PLAINS INTO UPPER MS VALLEY...
THE MODELS SHOW A PAIR OF LOW PRESSURE CENTERS-THE FIRST OVER
ONTARIO ON DAY TWO DRIVES A COLD FRONT SLOWLY EAST ACROSS THE
NORTHERN PLAINS TO THE UPPER MS VALLEY. THE SECOND AREA IS THE
DEVELOPMENT OF LOW PRESSURE OVER THE CENTRAL PLAINS...WHICH MOVES
NORTHEAST ALONG THE FRONTAL BNDRY TO THE UPPER MS VALLEY ON THU. A
HIGH AMPLITUDE UPPER DIVERGENCE/LOWER CONVERGENCE COUPLET DEVELOPS
IN THE VICINITY OF THE FRONT IN THE UPPER MS VALLEY IN THE RIGHT
ENTRANCE REGION OF THE UPPER LEVEL JET.
THE MODELS ARE IN BETTER THAN AVERAGE AGREEMENT ON THE
AXIS/ORIENTATION OF SHOWERS/STORMS DEVELOPING ACROSS MN INTO SERN
SD/NWRN IA AND EASTERN NE.
THU NIGHT...THE UKMET/ECMWF/NAM MODELS SHOW A DEVELOPING 850 MB
CIRCULATION/FRONT DRIFTING NORTH ACROSS NORTHERN KS/MO TOWARDS
NE/IA. A STRONG 850 MB THETA-E ADVECTION MAXIMA IN THE AXIS OF
THE 850 MB JET SHOULD HELP TRIGGER SHOWERS/STORMS NORTH OF THE
BNDRY. THIS IS SUPPORTED BY A 30 MB DIVERGENCE MAXIMUM STREAKING
EAST NORTHEAST ACROSS SOUTHERN NE TO IA 00-12Z FRI.
HPC GENERALLY FOLLOWED A BLEND OF THE 12-00Z ECMWF/00Z UKMET/00Z
NAM/00Z CANADIAN GLOBAL 12Z WED-12Z THU...AND THE 12-00Z ECMWF/00Z
UKMET 12Z THU-12Z FRI.
...FLORIDA...
A GREAT DEAL OF MODEL SPREAD ON THE QPF OVER FL WHICH RELATES TO
WHETHER A CLOSED LOW DEVELOPS AND THE EXTENT OF LOW LEVEL MOISTURE
CONVERGENCE WITHIN THE LOW-MID LEVEL FLOW. THE NAM HAS THE BETTER
DEFINED SFC-700 MB LOW AND THE MOST RAINFALL...FOLLOWED BY THE
SREF MEAN AND ECMWF...WHICH APPEARS TO HAVE A GRID SCALE FEEDBACK
MAXIMA OVER THE FL KEYS.
THE WEAKER AND MORE PROGRESSIVE WAVE IN THE GFS/CANADIAN GLOBAL
RESULTS IN LOWER QPF AMOUNTS. MANUAL PROGS BLENDED THE 12-00Z
ECMWF/GFS UNTIL BETTER AGREEMENT DEVELOPS.
...MID-ATL INTO NORTHEAST...
A BROAD DIFFUSE MID/UPR LEVEL TROUGH NEAR THE SRN APPALACHIANS
WILL GRADUALLY WEAKEN AND FILL... WHILE DRIFTING OFF TO THE NORTH
AND EAST INTO THE MID-ATL STATES ON THURS. EXPECT DIURNALLY
ENHANCED SHOWERS/THUNDERSTORMS EACH DAY... WITH NIGHT
SHOWERS/STORMS WHERE LOCAL MAXIMA IN UPPER DIVERGENCE OCCUR. WITH
DEEP MOISTURE AND LITTLE DIRECTIONAL SHEAR/LIGHT DEEP LAYER
WINDS...SLOW MOVEMENT OF CELLS COULD GENERATE LOCALLY HEAVY
RAINFALL TOTALS. HPC FOLLOWED A BLEND OF THE 12-00Z ECMWF/00Z
UKMET FOR AREAL AVGS OF A .5 TO 1 INCH TOTALS EACH DAY. LESS
WEIGHTING WAS GIVEN TO THE GFS AS IT RAISES HEIGHTS FASTER THAN
THE ECMWF AS THE TROUGH GRADUALLY EJECTS FROM THE SOUTHEAST TO THE
MID ATLANTIC...AND THIS IS AN BIAS OF THE GFS TO MOVE UPPER
TROUGH/LOWS TOO QUICKLY.
PACIFIC NORTHWEST/NORTHERN ROCKIES...
OVER THE PACIFIC NW INTO THE NRN ROCKIES...DIFLUENT FLOW ALOFT
SOUTH OF AN UPPER LOW ALONG THE US/CANADIAN BORDER COMBINES WITH
PERSISTENT ONSHORE FLOW AND MOISTURE TRANSPORT TO YIELD MDT QPF
FROM COASTAL WA/OR TO THE NRN ROCKIES ON WED BEFORE CLOSED UPPER
LOW CENTER DROPS ACROSS WA/OR AND THE ONSHORE FLOW WEAKENS/MOVES
FURTHER SOUTH...ALONG WITH LOW LEVEL CONVERGENCE MAXIMA. MANUAL
PROGS BLENDED THE 12-00Z ECMWF/00Z UKMET/00Z NAM...WITH LESS
WEIGHT ON THE GFS...WHOSE HIGHER AMPLITUDE 700 MB CONVERGENCE
MAXIMA IN ID IS NOT REFLECTED IN THE OTHER MODELS.
