FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID JUN 17/1200 UTC THRU JUN 20/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR
UPDATE
THE PRELIM DAY 1 QPF WAS ADJUSTED FOR THE EVOLUTION OF THE
ORGANIZED CONVECTION. THIS COMPLEX IS BEGINNING TO WEAKEN BUT
SHOULD STILL PRODUCE SOME MODERATE AMOUNTS EARLY THIS PERIOD
ACROSS THE SOUTHERN PLAINS TOWARD THE LOWER MS VALLEY.
OVERALL---NO SIGNIFICANT CHANGES MADE TO THE PRELIM DAY 1 QPF FOR
THE FINAL ISSUANCE.
DAY 1
SOUTHERN PLAINS INTO THE LOWER MS VALLEY---TN VALLEY---CENTRAL
GULF COASTAL REGION AND SOUTHERN APPALACHIANS
A RATHER LOW CONFIDENCE FORECAST THIS PERIOD FROM THE SOUTHERN
PLAINS---EASTWARD INTO THE LOWER MS VALLEY AND TN VALLEY REGION.
ORGANIZED CONVECTION THAT IS MOVING VERY QUICKLY SOUTHEASTWARD
INTO THE SOUTHERN PLAINS WILL LIKELY WEAKEN BY OR SHORTLY AFTER
1200 UTC. AFTER THIS---UNCERTAINTIES ARE HIGH AS TO HOW
ADDITIONAL CONVECTION WILL DEVELOP. IN GENERAL---PW VALUES WILL
REMAIN ABOVE AVERAGE ACROSS THESE REGIONS---SUPPORTING POTENTIAL
FOR HEAVY RAINS WHERE ADDITIONAL CONVECTION DEVELOPS. WHERE THIS
ADDITIONAL ACTIVITY DEVELOPS MONDAY IS NOT VERY CERTAIN WITH LARGE
SPREADS IN QPF DETAILS AMONG THE LATEST SUITE OF MODELS. THERE
WILL BE ADDITIONAL SHORTWAVES MOVING ALONG THE SOUTHERN EDGE OF
THE WESTERLIES THAT COULD SPAWN ADDITIONAL ORGANIZED
CONVECTION---BUT WITH CONFIDENCE LOW---HEAVY AMOUNTS NOT DEPICTED
IN THE DAY 1 QPF. INSTEAD A BROAD REGION OF .25-.50"+ AREAL
AVERAGE AMOUNTS DEPICTED FROM THE SOUTHERN PLAINS---THROUGH THE
LOWER MS VALLEY---TN VALLEY---CENTRAL GULF COASTAL REGION INTO THE
SOUTHERN APPALACHIANS.
ACROSS THE CENTRAL PLAINS----EQUALLY LOW CONFIDENCE WITH
ADDITIONAL CONVECTION POTENTIAL HERE AS FOR POINTS FARTHER TO THE
SOUTH AND EAST. LOW LEVEL EASTERLY TO SOUTHEASTERLY FLOW MAY
RE-FOCUS INTO THE LEE OF THE CENTRAL ROCKIES/CENTRAL HIGH PLAINS
REGION LATE MONDAY AFTERNOON/EVENING---HELPING TO DEVELOP
ADDITIONAL CONVECTION THAT THEN PUSHES EASTWARD INTO THE CENTRAL
PLAINS. SIMILAR TO THE POTENTIAL CONVECTION ACROSS THE SOUTHERN
TIER---LARGE SPREADS IN MODEL QPFS AND RESULTANT LOW CONFIDENCE
HAS KEPT THE DAY 1 QPF FROM DEPICTING MORE THAN MODERATE AMOUNTS
IN THE .10-.25"+ AREAL AVERAGE RANGE.
COASTAL PACIFIC NORTHWEST
NO SIGNIFICANT MODELS DIFFERENCES WITH THE EASTWARD PUSH OF THE
STRONG NORTHEASTERN PACIFIC CLOSED LOW TOWARD THE PACIFIC
NORTHWEST THIS PERIOD. THE DAY 1 QPF DID NOT DEVIATE FROM THE
MODEL CONSENSUS OF LIGHT TO MODERATE AREAL AVERAGE AMOUNTS ALONG
COASTAL SECTIONS OF WA STATE AND OR.
NORTHERN TIER FROM THE UPPER MS VALLEY---GREAT LAKES INTO THE
NORTHEAST
SCATTERED CONVECTION POSSIBLE DAY 1 AHEAD OF A SURFACE FRONTAL
BOUNDARY SINKING SOUTHWARD ACROSS THE NORTHERN TIER OF THE COUNTRY
FROM THE UPPER MS VALLEY---THROUGH THE GREAT LAKES AND INTO THE
NORTHEAST. PW VALUES ARE NOT VERY HIGH IN THE VICINITY OF THIS
FRONT---GENERALLY BELOW SEASONAL NORMS. LOW CONFIDENCE WITH QPF
DETAILS ACROSS THESE AREAS--WITH LIGHT TO LOCALLY MODERATE
PRECIPITATION AMOUNTS DEPICTED.
DAYS 2/3...
...PACIFIC NORTHWEST/NORTHERN ROCKIES/NORTHERN PLAINS...
AN INCREASING SOUTH TO SOUTHEAST LOW LEVEL FLOW AHEAD OF A CLOSED
MID LEVEL LOW OVER THE PACIFIC NORTHWEST WILL TRANSPORT MOISTURE
FROM THE WESTERN PLAINS AND FUEL CONVECTION ACROSS THE REGION.
THE HIGHER MOISTURE SHOULD BE FOCUSED ON MT... RAISING THE SPECTER
FOR HEAVY TO LOCALLY EXCESSIVE RAINFALL AMOUNTS ACROSS PORTIONS OF
NORTHERN MT.
THE COMBINATION OF HEAVY RAIN AND RELATIVELY LOW FLASH FLOOD
GUIDANCE NUMBERS PROMPTED THE ISSUANCE OF A SLIGHT RISK FOR
EXCESSIVE RAINFALL AREA OF A PORTION OF NORTHERN MT ON DAY 3. THE
00Z MODEL SUITE CONTINUED TO SHOW GOOD CLUSTERING WITH RESPECT TO
THE EVOLUTION OF THE CLOSED LOW (WITH THE EXCEPTION OF THE 00Z
UKMET...WHICH WAS TOO FAST...AND THE 00Z CMC...WHICH LOOKED TOO
SLOW). THE QPF FORECAST WAS BASED PRIMARILY ON A 00Z ECMWF/GFS
BLEND.
THE DEEP CLOSED MID LEVEL LOW COMES ASHORE LATE DURING DAY 2. AS
THE CLOSED LOW ARRIVES...IT WILL RESULT IN LOWERING HEIGHTS ACROSS
THE PACIFIC NORTHWEST... STEEPENING LAPSE RATES AND PRODUCING
MARGINAL INSTABILITY. THE MID LEVEL FLOW SHOULD SUPPORT THE BEST
LIFT IN THE HIGHER TERRAIN...AND A SWATH OF 0.15 TO 0.35 INCHES OF
QPF WAS PLACED ACROSS THE OLYMPICS AND OR COASTAL RANGE ACROSS THE
WEST...AND 0.25 TO 0.50 IN PORTIONS OF THE CASCADES.
OVER ID AND MT...THE LOW LEVEL SOUTH TO SOUTHEAST FLOW WILL JUST
BE DEVELOPING DURING DAY 2. ON THE NOSE OF THE 20 TO 30 KNOT LOW
LEVEL INFLOW...PRECIPITABLE WATER VALUES WILL INCREASE TO CLOSE TO
AN INCH (WHICH IS TWO STANDARD DEVIATIONS ABOVE NORMAL) ACROSS THE
REGION. MODEL SOUNDINGS SHOW MARGINAL TO LOCALLY MODERATE
INSTABILITY...SO CONVECTION SHOULD PRODUCE AN AREA OF 0.20 TO 0.40
INCHES OF QPF ACROSS NORTHERN ID AND WESTERN MT.
SHORT WAVES RIDING THROUGH THE EASTERN SIDE OF THE CLOSED MID
LEVEL SYSTEM WILL HELP SPARK CONVECTION ACROSS THE PACIFIC
NORTHWEST ON DAY 3. COOLING MID LEVEL TEMPERATURES WILL RESULT IN
MARGINAL INSTABILITY...AS PRECIPITABLE WATER VALUES REACH NEAR
0.75 INCHES. THE COMBINATION OF MOISTURE AND INSTABILITY SHOULD
FAVOR CONVECTIVE DEVELOPMENT...FOCUSED ON THE HIGHER
TERRAIN...PRODUCING A SWATH OF 0.25 TO 0.50 INCHES OF QPF ON THE
HIGHER TERRAIN OF WA AND OR.
ACROSS NORTHERN ID AND WESTERN MT...THE 25 T0 35 KNOT INFLOW WILL
TRANSPORT 1.25 INCH PRECIPITABLE WATER VALUES (WHICH IS BETWEEN
TWO AND THREE STANDARD DEVIATIONS ABOVE NORMAL) INTO NORTHERN AND
EASTERN MT. THE EAST SOUTHEAST FLOW WILL FOCUS THE MOISTURE ON THE
HIGHER TERRAIN ALONG A FAIRLY STRONG PACIFIC FRONT (WITH AN
ANOMALOUS LOW PRESSURE SYSTEM ON THE FRONT). MODEL SOUNDINGS SHOW
MODERATE INSTABILITY IN THE AREA...WITH GOOD LOW LEVEL
VEERING...WHICH COULD SUPPORT CONVECTIVE CLUSTERS. THE COMBINATION
OF MOISTURE AND INSTABILITY SHOULD BE FOCUSED ON NORTHERN ID AND
NORTHERN MT...WHERE A LARGE AREA OF 0.75 TO 1.25 INCHES OF QPF WAS
PLACED. THESE NUMBERS WOULD SURPASS THE THREE HOUR FLASH FLOOD
GUIDANCE VALUES. BECAUSE OF THIS...A SLIGHT RISK AREA WAS PLACED
OVER NORTHERN MT.
...CENTRAL/SOUTHERN ROCKIES...
A DEVELOPING UPSLOPE FLOW IN AN INCREASINGLY MOIST ENVIRONMENT
SHOULD RESULT IN CONVECTION ACROSS THE SOUTHERN AND CENTRAL
ROCKIES...MAINLY DURING DAY 2. THE 00Z MODEL SUITE HAD GOOD
CLUSTERING WITH RESPECT TO THE OVERALL PATTERN...AND THE QPF
FORECAST WAS BASED ON A 00Z ECMWF/GFS/NAM BLEND.
A DEVELOPING 25 TO 35 KNOTS SOUTH SOUTHEAST LOW LEVEL JET WILL
TRANSPORT PRECIPITABLE WATER VALUES NEAR AN INCH (WHICH IS BETWEEN
ONE AND TWO STANDARD DEVIATIONS ABOVE NORMAL) INTO THE REGION.
MODEL SOUNDINGS SHOW MARGINAL TO LOCALLY MODERATE INSTABILITY WITH
GOOD LOW LEVEL VEERING...SUGGESTING SOME ORGANIZATION OF THE
CONVECTION ON THE FRONT RANGE. INITIATION SHOULD OCCUR DURING THE
AFTERNOON...AND THE ORGANIZED CONVECTION COULD LAST INTO THE LATE
EVENING AS IT ROLLS EASTWARD.
THE COMBINATION OF MOISTURE AND INSTABILITY SHOULD RESULT IN AN
AREA OF 0.25 TO 0.50 INCHES OF QPF STRETCHING FROM SOUTHEAST WY
ACROSS THE EASTERN THIRD OF CO.
...CENTRAL/SOUTHERN PLAINS INTO THE SOUTHEAST STATES...
A STATIONARY FRONT STRETCHED FROM THE CENTRAL AND SOUTHERN PLAINS
TO THE SOUTHEAST STATES WILL BE THE FOCUS FOR QPF ON BOTH DAYS 2
AND 3. THE LATEST 00Z ECMWF DID NOT APPEAR TO HANDLE THE DETAILS
ON THE FRONTAL POSITION AS WELL AS ITS PREDECESSOR...SO THE QPF
FORECAST WAS BASED ON A 00Z GFS/12Z ECMWF BLEND.
THERE COULD BE AN MCS IN THE PROCESS OF DECAYING AT THE BEGINNING
OF DAY 2 ACROSS THE CENTRAL PLAINS. ITS ASSOCIATED MCV COULD THEN
BECOME A SOURCE OF LIFT ACROSS THE SOUTHERN PLAINS INTO THE LOWER
MS VALLEY AND LOWER OH VALLEY DURING THE REMAINDER OF DAY 2. MODEL
SOUNDINGS AHEAD OF THE MCV (OR WEAK MID LEVEL SHORT WAVES) SHOW
MODERATE TO STRONG INSTABILITY ACROSS THE STATIONARY FRONT...WHICH
WILL ACT TO FOCUS THE CONVECTION. PRECIPITABLE WATER VALUES
RANGING BETWEEN 1.75 AND 2.00 INCHES WILL FUEL THE
CONVECTION...RESULTING IN A LONG BAND OF 0.75 TO 1.25 INCHES OF
QPF ACROSS THE ABOVEMENTIONED AREA. NONE OF THESE QPF VALUES ARE
ABOVE THE THREE HOUR FLASH FLOOD GUIDANCE NUMBERS...SO NO
ORGANIZED FLOODING IS EXPECTED.
AS THE FRONT DROPS SOUTH ON DAY 3...THE FOCUS FOR CONVECTION AND
QPF DROP SOUTH WITH IT. THERE DOES NOT APPEAR TO BE AS MUCH FOCUS
IN THE MID LEVELS...SO THE CONVECTION MAY TEND TO BE MORE
SCATTERED THAN DAY 2. THE OVERALL AIRMASS DOES NOT CHANGE...SO
LOCALLY HEAVY RAIN IS POSSIBLE IN CONVECTION ALONG THE FRONT. THIS
SHOULD SUPPORT 0.50 TO 1.00 INCHES OF QPF ACROSS THE LOWER MS
VALLEY INTO GA AND SC.
...SOUTHERN NEW ENGLAND/MID ATLANTIC...
A FRONT DROPPING SOUTH THROUGH SOUTHERN NEW ENGLAND AND THE
NORTHERN MID ATLANTIC STATES LATE ON DAY 2 WILL BECOME THE FOCUS
FOR CONVECTION. LOW PRESSURE DEVELOPING ON THE FRONT LATE IN DAY 2
INTO DAY 3 COULD PRODUCE A LARGER AREA OF PRECIPITATION DURING DAY
3. THERE WAS GOOD 00Z MODEL CLUSTERING CONCERNING THE MID
LEVELS...THOUGH THERE WAS SOME SPREAD ON JUST HOW FAST TO BRING
THE SURFACE FRONT SOUTH...THEN WHERE TO PLACE THE SURFACE WAVE ON
IT. TO HELP SMOOTH OUT THE DIFFERENCES...THE QPF WAS BASED ON A
00Z ECMWF/GFS BLEND.
A SHORT WAVE MOVING FROM THE GREAT LAKES TO THE MID ATLANTIC
STATES WILL HELP PROVIDE GENERAL SYNOPTIC LIFT AHEAD OF THE FRONT
ON DAY 2. THE WEST SOUTHWEST FLOW AHEAD OF THE SOUTHWARD DROPPING
FRONT WILL USHER IN PRECIPITABLE WATER VALUES AS HIGH AS 1.75
INCHES INTO THE REGION AHEAD OF THE FRONT. THE MOISTURE WILL HELP
FUEL CONVECTION NEAR THE FRONT...AIDED BY DIFLUENCE ASSOCIATED
WITH THE RIGHT REAR QUADRANT OF A 90 KNOT JET STREAK OVER NORTHERN
NEW ENGLAND. THE CONVECTION SHOULD MOVE ALONG THE FRONT...AS MODEL
SOUNDINGS SHOWED UNIDIRECTIONAL SHEAR. THE HIGH PRECIPITABLE WATER
RAISES THE POTENTIAL FOR LOCALLY HEAVY RAIN...IN THE FORM OF A
SWATH OF 0.75 TO 1.25 INCHES OF QPF STRETCHING FROM SOUTHERN NEW
ENGLAND INTO MD AND VA. THESE VALUES ARE ABOVE THE THREE HOUR
FLASH FLOOD GUIDANCE NUMBERS...SO NO ORGANIZED FLASH FLOOD THREAT
IS EXPECTED.
AS THE FRONT DROPS SOUTH...THERE IS MODEL CONSENSUS THAT A SURFACE
LOW WILL DEVELOP ON THE FRONT IN RESPONSE TO LIFT AHEAD OF A MID
LEVEL SHORT WAVE. THE MID LEVEL FRONTOGENETIC FORCING ASSOCIATED
WITH THE SURFACE LOW AND SHORT WAVE COULD ENHANCED RAINFALL ACROSS
THE MID ATLANTIC STATES ON DAY 3...WITH 0.25 TO 0.50 INCHES OF QPF
POSSIBLE.
...FL....
MAINLY DIURNAL CONVECTION DRIVEN BY A MOIST EAST SOUTHEAST FLOW
WILL AFFECT THE PENINSULA ON DAY 2. THE 00Z MODEL SUITE CLUSTERED
WELL CONCERNING THE OVERALL SYNOPTIC PATTERN...SO THE QPF FORECAST
WAS BASED ON A 00Z ECMWF/GFS/NAM BLEND.
HIGH RESOLUTION MODELS SUGGEST THAT THE EASTERN SEA BREEZE
CONVERGENCE WILL BE THE MAIN FOCUS FOR CONVECTION. MODEL SOUNDINGS
SHOW MARGINAL TO LOCALLY MODERATE INSTABILITY IN A WEAKLY SHEARED
ENVIRONMENT...WITH INITIATION DURING THE EARLY AFTERNOON.
PRECIPITABLE WATER VALUES AT OR ABOVE 1.75 INCHES SUGGEST THAT THE
CONVECTION COULD LAST A COUPLE OF HOURS AFTER 00Z. A STRIPE OF
0.15 TO 0.25 INCHES PF QPF WAS PLACED IN THE EXPECTED VICINITY OF
THE CONVECTION.
