Flood in Rhode Island, June 21, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
944 AM EDT SUN JUN 21 2015

.SYNOPSIS...

REMNANTS OF TROPICAL STORM BILL WILL BRING A PERIOD OF HEAVY RAIN
THIS MORNING FOLLOWED BY DRIER WEATHER THIS AFTERNOON AS IT MOVES
INTO THE GULF OF MAINE. WARM AND DRY WEATHER FOLLOWS MONDAY. THERE
IS THE POSSIBILITY OF STRONG TO SEVERE WEATHER FOR TUESDAY. QUIET
WEATHER FOR WEDNESDAY INTO THURSDAY. AN UNCERTAIN FORECAST FRIDAY
INTO NEXT WEEK THOUGH A MORE ACTIVE PATTERN APPEARS PLAUSIBLE.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

***RAIN ENDS BY EARLY AFTERNOON IN MOST LOCATIONS FOLLOWED BY AN
  EXTENDED PERIOD OF DRY WEATHER***

***A FEW MARGINALLY STRONG THUNDERSTORMS WITH GUSTY WINDS ARE
  POSSIBLE ACROSS WESTERN MA AND NORTHERN CT BETWEEN 5 AND 9 PM THIS
  EVENING***

943 AM UPDATE...

CLUSTER OF STRONG THUNDERSTORMS WITH BRIEF HEAVY RAIN/LIGHTNING
PRODUCING 30 TO 45 MPH WERE EXITING THE CAPE/ISLANDS AT MID TO LATE
MORNING.  OTHERWISE...NUMEROUS SHOWERS WERE STILL AFFECTING MUCH OF
SOUTHERN NEW ENGLAND.  WILL CONTINUE THE FLOOD WATCH FOR ANOTHER
HOUR OR TWO ACROSS RI/SOUTHEAST MA...WHERE SOME POOR DRAINAGE STREET
FLOODING IS STILL POSSIBLE.  WILL PROBABLY BE ABLE TO CANCEL BY NOON.

OTHERWISE...MOST AREAS SHOULD BE DRY BY MID AFTERNOON.  IN
FACT...EXPECT TO SEE PARTIAL SUNSHINE EMERGE AT LEAST ACROSS THE
INTERIOR DURING THE AFTERNOON.  THIS WILL RESULT IN A LATE DAY RALLY
WITH REGARDS TO TEMPS.  EXPECT MAX TEMPS BY LATE AFTERNOON TO REACH
INTO THE LOW/MID 80S IN THE CT VALLEY WITH THE EXPECTATION OF PARTLY
SUNNY SKIES DEVELOPING...AND UPPER 70S REST OF SNE EXCEPT COOLER S
COAST.

AFTER AN EXTENDED PERIOD OF DRY WEATHER A SHORTWAVE WILL APPROACH
OUR WESTERN ZONES...PROBABLY AFTER 5 PM.  0 TO 6 KM SHEAR VALUES ARE
PRETTY GOOD ON THE ORDER OF 35 TO 40 KNOTS...BUT NOT SURE THAT WILL
BE ABLE TO MUSTER MORE THAN 500 TO 1000 J/KG OF CAPE AND MID LEVEL
LAPSE RATES ARE WEAK.  NONETHELESS...THE RISK FOR SCATTERED SHOWERS
AND A FEW THUNDERSTORMS ARE EXPECTED IN WESTERN MA/NORTHERN BETWEEN
5 AND 9 PM.  A FEW OF THE THUNDERSTORMS MAY BE STRONG AND RESULT IN
LOCALIZED STRONG WIND GUSTS...BUT PROBABLY WILL REMAIN BELOW SEVERE
LIMITS. AFTER THAT TIME...ACTIVITY SHOULD WEAKEN WITH PERHAPS JUST A
FEW BRIEF SPOT SHOWERS SURVIVING INTO EASTERN NEW ENGLAND LATER THIS
EVENING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
A FEW SHOWERS/TSTMS POSSIBLE IN THE EVENING ACROSS W MA AND N
CT...OTHERWISE A MAINLY DRY NIGHT AS REMNANT LOW PRES LIFTS NE
FROM THE GULF OF MAINE. A MUGGY NIGHT WITH LOWS IN THE 60S AND
EXPECT SOME STRATUS AND PATCHY FOG...ESPECIALLY CAPE/ISLANDS.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
*/ HIGHLIGHTS...

 - FAIR WEATHER AND QUIET FOR MONDAY INTO MONDAY NIGHT
 - SEVERE WEATHER POSSIBLE FOR TUESDAY...SOME UNCERTAINTY
 - SLIGHTLY BELOW SEASONABLY AND DRY WEDNESDAY-THURSDAY
 - AN UNCERTAIN FORECAST FOR THE LATE-WEEK / WEEKEND PERIOD

*/ DISCUSSION...

QUIET PATTERN FOR MONDAY INTO MONDAY NIGHT. WEAK RIDGING AND HIGH
PRESSURE DURING THE DAY. FAIR WEATHER CONDITIONS WITH A MIX OF SUN
AND CLOUDS WARMING INTO THE 80S FOR MUCH OF THE REGION. W/NW-FLOW.
OVERNIGHT...WARM-FRONT ALOFT LIFTING THROUGH THE AREA THOUGH BENEATH
THE RIGHT-EXIT REGION OF THE UPPER-LEVEL-JET. AN UNFAVORABLE REGION
OF DEVELOPMENT SO EXPECT JUST STREAMING AND THICKENING CLOUDS ACROSS
THE AREA AS WINDS INCREASE OUT OF THE S PER AN ISALLOBARIC RESPONSE.
BETTER WET-WEATHER CHANCES N AND W ASSOCIATED WITH THE CLOSED LOW
OVER THE N GREAT LAKES REGION AND TIGHTER THERMAL PACKING E OF THE
LOW BENEATH THE ACCOMPANYING LEFT-EXIT REGION OF THE UPPER-LEVEL-JET.

TUESDAY COULD BE A POTENTIALLY DANGEROUS SITUATION WITH A POSSIBLE
SEVERE WEATHER OUTBREAK. NOT FULLY CERTAIN AS THERE ARE BOTH SPATIAL
AND TEMPORAL CONSIDERATIONS. FORECAST SOLUTIONS CONTINUE TO WOBBLE
WITH RESPECT TO POTENTIAL ENVIRONMENTS AND FRONTAL TIMING. ECHO THE
PREVIOUS FORECASTER...TRYING TO FORECAST A POTENTIAL SEVERE WEATHER
EVENT IN ADVANCE IS CHALLENGING...EVEN MORE DIFFICULT THAN A WINTER
STORM SINCE MANY MORE MESOSCALE FEATURES GO INTO THE CONVECTIVE
PROCESSES. BASED ON A CONSENSUS OF FORECAST GUIDANCE MINUS THE 21.0Z
NAM WHICH APPEARS TO BE AN OUTLIER /93 OVER 73 IN HARTFORD AT 2M AT
18Z/ HERE IS WHAT IS WORTH NOTING:

SYNOPTICALLY...WARM FRONT LIFTS N/E DURING THE MORNING HOURS PERHAPS
STALLING IN VICINITY TO THE E-COAST AGAINST COOLER WATERS ASSOCIATED
WITH THE GULF OF MAINE. STRONG SW-FLOW IN RESPONSE TO THE DEEPENING
LOW TO THE N YIELDS AN ENVIRONMENT OF RICH-DEEP WARM-MOIST AIR INTO
THE INTERIOR NE-CONUS AHEAD OF A SWEEPING COLD FRONT PARENT TO THE
LOW. LOOKING AT A STRONG PUNCH OF HIGH THETA-E AIR AHEAD OF THE COLD
FRONT IN AN ENVIRONMENT OF STRONG DEEP-LAYER SHEAR ESPECIALLY AT 0-1
KM ORIENTED ROUGHLY PERPENDICULAR TO THE FRONT WHILE PARALLEL TO THE
MEAN-WIND. 0-1 KM VALUES AVERAGING 20-30 KTS WITH 0-3 AT 40-50 KTS.
WOULD BE PARTICULARLY CONCERNED IF WE GOT A MORE S-COMPONENT OF THE
WIND LIKE THROUGH THE CT-RIVER-VALLEY.

UNCERTAIN...IS WHETHER THE ENVIRONMENT IS PRIMED FOR STRONG - SEVERE
WEATHER. TO CONSIDER...H85-7 TEMPERATURES COULD BE CONSIDERABLY WARM
AT +20-22 AND +10-12 RESPECTIVELY TO CAP THE BOUNDARY-LAYER LIMITING
CAPE. COULD ALSO HAVE ISSUES WITH CONVECTIVE DEBRIS FROM UPSTREAM.
NEVERTHELESS A CONSENSUS OF THE FORECAST GUIDANCE HAS AN AVERAGE OF
1K-2K J/KG MUCAPE WITH A CONSENSUS RANGE FROM 500-4500 J/KG BELIEVED
TO BE CONSEQUENTIAL OF TIMING OF THE LOW / FRONTS WHICH ARE CRITICAL
AS TO WHETHER THERE IS ENOUGH SUNSHINE ALLOWING THE BOUNDARY-LAYER
DESTABILIZATION. ALSO TO BE CONSIDERED IS WHETHER AN ELEVATED MIXED
LAYER /H5-7/ IS A PART OF THE EQUATION THOUGH A FORECAST CONSENSUS
HAS IT SLIPPING AHEAD OF A POTENTIAL FAVORABLE LOW-LEVEL ENVIRONMENT
AND SWEEPING COLD FRONT...AND WHETHER A MODIFIED MARINE LAYER SLIPS
ONSHORE WITH THE EXPECTED S-FLOW.

ALTOGETHER...NOTING THE SHEAR AND POTENTIAL INSTABILITY COUPLED WITH
A FORCING COLD FRONT AND ACCOMPANYING MID-LEVEL IMPULSE ANTICIPATED
TO SWEEP THROUGH THE REGION ALBEIT THE TIMING SOMEWHAT UNCERTAIN...
THERE IS SOME LEVEL OF FORCING AND IT WOULD APPEAR THAT SOMETHING
HAS GOT TO GIVE DURING THE MIDDAY INTO EVENING TIMEFRAME. SPC DY3
OUTLOOK PRESENTLY HAS N/W FORECAST AREAS IN A SLIGHT RISK WITH THE
MAIN THREAT BEING DAMAGING WINDS IN AN ENVIRONMENT OF DEEP-LAYER
SHEAR.

EVALUATING CIPS ANALOGS THERE IS ENOUGH BELIEF THAT SOME SORT OF
CONVECTIVE WEATHER WILL MANIFEST ITSELF BUT NOT ENTIRELY SURE HOW
STRONG TO SEVERE. BEARS WATCHING. WILL NEED TO KEEP AN EYE OUT ON
THE ENVIRONMENT AND CONVECTIVE MODES IF ANY THAT ORIGINATE ACROSS
THE GREAT LAKES REGION MONDAY. SPC PRESENTLY HAS THIS AREA UNDER AN
ENHANCED SEVERE WEATHER OUTLOOK WITH THE ANTICIPATION OF A REGIONAL
SEVERE WEATHER THREAT. IF THE ENVIRONMENT EXPECTED TO TRANSLATE FROM
THE GREAT LAKES INTO THE NE-CONUS IS ESPECIALLY BAD AND DANGEROUS ON
MONDAY...THEN NEARLY MUCH OF THE SAME COULD BE EXPECTED FOR US ON
TUESDAY.

TUESDAY NIGHT APPEARS QUIET AS THE COLD FRONT AND CONVECTIVE THREAT
PUSH OFFSHORE. W/NW WINDS PREVAILING AS HIGH PRESSURE BUILDS INTO
THE REGION LINGERING FOR BOTH WEDNESDAY-THURSDAY PROVIDING SLIGHTLY
COOLER-THAN-AVERAGE CONDITIONS. THE FORECAST HEREAFTER IS FAIRLY
UNCERTAIN. A PATTERN CHANGE AMONG DETERMINISTIC / ENSEMBLE SOLUTIONS
IS EVIDENT WITH A MONSOONAL HIGH OVER THE INTER-MOUNTAIN WEST AND
PREFERRED TROUGHING TO THE EAST. BUT KNOWING EXACT SURFACE OUTCOMES
ACROSS THE NE-CONUS FOR THE LATE-WEEK INTO WEEKEND TIMEFRAME IS
LARGELY UNKNOWN AS RUN-TO-RUN CONSISTENCY AMONG FORECAST GUIDANCE
HAS BEEN POOR OF LATE. A MORE ACTIVE WEATHER PATTERN IS SPECULATED.
