AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE TAUNTON MA  
108 PM EST FRI JAN 12 2018  
   
SYNOPSIS
 
 
MULTIPLE LOW PRESSURE AREAS ALONG AN APPROACHING COLD FRONT WILL  
BRING HEAVY RAINFALL, POTENTIAL FLOODING AND GUSTY WINDS LATER TODAY  
AND TONIGHT. A SHARP TURN TO MUCH COLDER WEATHER OCCURS RAPIDLY  
SATURDAY WHICH WILL ALLOW RAIN TO END AS A BIT OF LIGHT FREEZING  
RAIN AND SLEET ...BUT MORE IMPORTANTLY A FLASH FREEZE IS EXPECTED  
ACROSS ALL OF SOUTHERN NEW ENGLAND. MAINLY DRY BUT COLD WEATHER  
IS EXPECTED SUNDAY AND MONDAY, BUT WILL HAVE TO WATCH THE  
POTENTIAL FOR SOME SNOW MID WEEK.  
 

 
   
NEAR TERM /UNTIL 6 PM THIS EVENING/
 
 
***HEAVY RAINFALL DEVELOPING THIS AFTERNOON ACROSS WESTERN MA  
AND NORTHERN CT***  
 
***NEAR RECORD HIGH TEMPS THIS AFTERNOON***  
 
1 PM UPDATE...  
 
BAND OF HEAVY RAIN ACROSS FAR WESTERN MA AND SLOWLY MOVING  
EAST. FOCUS FOR HEAVY RAINFALL WILL REMAIN ACROSS WESTERN MA AND  
NORTHERN CT WHERE 1-2 INCHES IS POSSIBLE. SHOWERS HAVE MOVED  
EAST ACROSS RI AND EASTERN MA WHERE LOW LEVEL JET IS SUPPLYING  
LOW LEVEL CONVERGENCE, BUT HEAVY RAIN IN THE COASTAL PLAIN WILL  
HOLD OFF UNTIL EVENING.  
 
RECORD HIGH TEMP HAS BEEN BROKEN AT BDL AND TIED AT ORH. WITHIN  
ONE DEGREE AT BOS/PVD.  
 
GETTING SOME GUSTS TO 40 MPH ACROSS RI AND SE MA WHERE TEMPS  
AROUND 60 ENHANCING LOW LEVEL MIXING. THIS WILL CONTINUE THIS  
AFTERNOON WITH GUSTS 40-50 MPH POSSIBLE.  
 
PREVIOUS DISCUSSION...  
 
RAIN IS OVERSPREADING WESTERN NEW ENG LATE THIS MORNING AND  
WILL CONTINUE TO SLOWLY MOVE EAST THROUGH THE AFTERNOON.  
STRONGEST FORCING FOR ASCENT FOCUSED ACROSS THE WEST THIS  
AFTERNOON ALONG THE AXIS OF THE 850MB JET WHERE HEAVY RAINFALL  
IS LIKELY. IN FACT, THE HI-RES GUIDANCE IS INDICATING 1-2 INCHES  
OF RAIN ACROSS WESTERN MA AND NORTHERN CT WITH LOCALLY HIGHER  
AMOUNTS. SOME MARGINAL ELEVATED INSTABILITY SUPPORTS ISOLD  
THUNDER IN THE WEST AS WELL. AREAS OF URBAN AND POOR DRAINAGE  
FLOODING IS EXPECTED WHICH WILL IMPACT THE EVENING COMMUTE IN  
WESTERN NEW ENG.  
 
ACROSS EASTERN NEW ENG, MAINLY DRY CONDITIONS WILL PREVAIL INTO  
THE AFTERNOON WITH JUST A FEW SHOWERS POSSIBLE. LEADING EDGE OF  
STEADIER RAINFALL WILL APPROACH THE I-95 CORRIDOR BY LATE  
AFTERNOON BUT PORTIONS OF FAR SE MA AND CAPE/ISLANDS MAY REMAIN  
MOSTLY DRY THROUGH THE DAYLIGHT HOURS OTHER THAN A FEW SHOWERS.  
 
TEMPS ALREADY WELL INTO THE 50S AND WILL SEE SOME HIGH INTO THE  
LOWER 60S ACROSS PORTIONS OF RI AND EASTERN MA. NEAR OR RECORD  
HIGH TEMPS LIKELY ACROSS PORTIONS OF SNE. WINDS WILL BE  
INCREASING WITH THE WARMER TEMPS HELPING TO ENHANCE LOW LEVEL  
MIXING IN THE COASTAL PLAIN WHERE GUSTS 30-40 MPH POSSIBLE  
MID/LATE AFTERNOON. STRONGER GUSTS POSSIBLE TONIGHT AS CORE OF  
LLJ MOVES INTO THE REGION.  
 
STILL SOME PATCHY DENSE FOG IN THE CT VALLEY AND HIGHER  
ELEVATIONS IN CENTRAL MA, BUT VSBYS ARE IMPROVING AND EXPECT  
THIS TO CONTINUE AS RAIN OVERSPREADS THE REGION.  
 

 
   
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
 
 
***UNSEASONABLY MILD THIS AFTERNOON AND INTO TONIGHT WITH HEAVY RAIN  
OVERSPREADING THE REGION ALONG WITH THE POTENTIAL FOR SIGNIFICANT  
URBAN STREET FLOODING***  
 
***FLASH FREEZE SATURDAY ALONG WITH A BRIEF PERIOD OF FREEZING  
RAIN/SLEET***  
 
THIS AFTERNOON AND TONIGHT  
 
ANOMALOUS HIGH PWATS 4-5 STANDARD DEVIATIONS ABOVE NORMAL COUPLED  
WITH A SOUTHWEST LOW LEVEL JET 3+ ABOVE NORMAL WILL SET THE STAGE  
FOR HEAVY RAIN AND POTENTIAL FLOODING. WHILE SHOWERS WILL INCREASE  
IN COVERAGE DURING THE AFTERNOON...THE HEAVIEST OF THE RAIN WILL  
PROBABLY HOLD OFF UNTIL LATE AFTERNOON ACROSS THE INTERIOR AND THE  
EVENING ACROSS EASTERN MA/RI. THE RAIN WILL CONTINUE HEAVY AT TIMES  
THROUGH TONIGHT. THIS IS WHEN THE STRONG FORCING ACTS ON PWATS  
AROUND OR EVEN A BIT HIGHER THAN 1.5 INCHES. THE STRONG SOUTHWEST  
LOW LEVEL JET WILL ALSO ALLOW MILDER AIR TO MIX DOWN FROM ABOVE  
BRINGING AFTERNOON HIGH TEMPERATURES INTO THE UPPER 50S AND LOWER  
60S. THESE TEMPERATURES WILL NOT FALL MUCH TONIGHT LEADING TO RAPID  
SNOWMELT.  
 
PUTTING IT ALL TOGETHER...HEAVY RAINFALL COUPLED WITH RAPID SNOWMELT  
WILL RESULT IN A SIGNIFICANT URBAN STREET FLOODING THREAT MAINLY  
LATE THIS AFTERNOON AND INTO TONIGHT. DEWPOINTS RISING WELL INTO  
THE 50S WILL RESULT IN MUCAPE VALUES OF A FEW HUNDRED J/KG, SO  
CERTAINLY THE RISK FOR A RUMBLE OR TWO OF THUNDER. OVERALL...EXPECT  
STORM TOTAL RAINFALL OF 1 TO 3 INCHES WITH LOCALIZED 4 INCH  
AMOUNTS POSSIBLE. SOME GUIDANCE SUGGESTS THE BEST CHANCE FOR  
THESE HIGHER AMOUNTS WILL OCCUR ACROSS SOUTHEAST NEW ENGLAND ON  
THE NOSE OF THE LOW LEVEL JET. SOME OTHER DATA SUGGESTS IT MAY  
OCCUR FURTHER BACK INTO THE INTERIOR WHERE SOME ENHANCED SURFACE  
CONVERGENCE MAY OCCUR. ULTIMATELY...THIS WILL COME DOWN TO MANY  
MESOSCALE FACTORS BUT THE MAIN IDEA IS THE POTENTIAL FOR  
SIGNIFICANT URBAN STREET FLOODING EXISTS ESPECIALLY WITH SNOW  
CLOGGED STORM DRAINS. SOME MINOR RIVER AND STREAM FLOODING IS  
ALSO POSSIBLE AND WE CAN NOT RULE OUT ISOLATED ICE JAM FLOODING  
GIVEN THE BITTER COLD OF THE LAST TWO WEEKS.  
 
WE ALSO DID HOIST A WIND ADVISORY TONIGHT FOR THE FAR SOUTHEAST NEW  
ENGLAND COAST. DESPITE THE STRONG INVERSION IN PLACE...MOST OF THE  
MESOSCALE MODEL GUIDANCE WAS SHOWING A SOUTHWEST 925 MB LOW LEVEL  
JET OF OVER 80 KNOTS. ANY CONVECTION OR HEAVIER RAIN ELEMENTS MAY  
BRING SOME OF THAT WIND DOWN BEGINNING THIS EVENING AND THROUGH  
DAYBREAK SATURDAY. THEREFORE...FELT THE POTENTIAL FOR SOME 40 TO 50  
MPH WIND GUSTS WARRANTED THE WIND ADVISORY.  
 
SATURDAY  
 
RAPIDLY CHANGING WEATHER CONDITIONS AS TEMPERATURES CRASH FROM THE  
50S TO NEAR 60 AND INTO THE 20S FROM NORTHWEST TO SOUTHEAST IN A  
MATTER OF HOURS. WE DO NOT OFTEN SEE TEMPERATURES DROP THAT QUICKLY  
IN THIS PART OF THE COUNTRYBUT ONCE THE COLD FRONT CROSSES SHALLOW  
COLD AIR WILL SURGE INTO THE REGION. WHILE THE BULK OF THE  
PRECIPITATION WILL LIKELY BE OVER BY THE TIME TEMPERATURES DROP  
BELOW FREEZING...THERE IS LIKELY TO BE A BRIEF PERIOD OF LIGHT  
FREEZING RAIN/FREEZING DRIZZLE AND SLEET. WE ARE ACTUALLY MORE  
CONCERNED THOUGH ABOUT A FLASH FREEZE GIVEN ALL THE RAIN THAT WERE  
EXPECTING THROUGH DAYBREAK SATURDAY. USUALLY MOST OF OUR FLASH  
FREEZES OCCUR WHEN WINDS TURN NORTH TO NORTHEAST AS OPPOSED TO  
NORTHWEST AS WE ARE EXPECTING ON SATURDAY. HOWEVER, GIVEN THE RAPID  
TEMPERATURE DROP DO NOT THINK WILL BE ABLE TO DRY UP FAST ENOUGH TO  
PREVENT AT LEAST SOME ISSUES. THEREFORE...WE HAVE HOISTED A WINTER  
WEATHER ADVISORY GENERALLY ALONG AND NORTHWEST OF A BOSTON TO  
PROVIDENCE CORRIDOR. IT IS MAINLY FOR THE FLASH FREEZE CONCERN, BUT  
ALSO FOR THE POTENTIAL FOR A BIT OF LIGHT FREEZING RAIN/FREEZING  
DRIZZLE.  
 

 
   
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
 
 
*/ HIGHLIGHTS...  
 
- COLD SUNDAY THROUGH MONDAY, OCEAN-EFFECT SNOWS OVER  
CAPE/ISLANDS  
 
- POTENTIAL WINTER STORM TUESDAY INTO WEDNESDAY  
 
OVERVIEW AND MODEL PREFERENCES...  
SHIFT TOWARD POSITIVE NAO/AO AND PNA AS ROBUST BLOCKING RIDGES  
FORM ACROSS THE W CONUS AND THE N CENTRAL ATLANTIC. PV ANALYSES  
SUGGEST THE RESULTING PHASED POSITIVE HEIGHT ANOMALIES BETWEEN  
THESE TWO BLOCKS THEN FORCE A LOBE OF THE BAFFIN ISLAND VORTEX S  
AS A COLD UPPER LVL CUTOFF, WHICH THEN SETTLES ACROSS THE GREAT  
LAKES THROUGH EARLY NEXT WEEK. BAROCLINIC ZONE E OF THIS CUTOFF  
WILL PROVIDE THE LOWER LVL MECHANISM BY WHICH SFC LOW PRES  
DEVELOPS, BENEATH THE EASTWARD SHIFTING POLEWARD EXIT REGION OF  
THE JET ROTATING S OF THE CUTOFF AND LONGWAVE TROF. THIS LOW  
PRES, AND THE POTENTIAL FOR TYPICAL COASTAL ENERGY TRANSFER IS  
THE FOCUS FOR TUE AND WED, SUGGESTING A RISK FOR A WINTER STORM.  
THE BREAKDOWN OF THE POSITIVE PNA AS SHORTWAVE SHIFTS ONSHORE  
FROM THE PACIFIC WILL FORCE THE CUTOFF AND LONGWAVE TROF TO  
SHIFT TO THE E, BUT BOTH DETERMINISTIC AND ENSEMBLE PROGS VARY  
GREATLY WITH THE RESULTING DEPTH OF THE WAVE AS IT SHIFTS TOWARD  
NEW ENGLAND, WHICH ALTHOUGH IT ALLOWS DRIER CP AIR TO FILTER  
IN, MAKES FOR AN UNCERTAIN THERMAL FORECAST. GIVEN THE GRADUAL  
BREAKDOWN IN MASS/THERMAL FIELD AGREEMENTS BEGINNING WITH THE  
MID WEEK SYSTEM, WILL CONTINUE TO LEAN MOST HEAVILY ON ENSEMBLE  
MEANS TO ACCOUNT FOR THE FULL ENVELOPE OF POTENTIAL SOLUTIONS.  
 
DETAILS...  
 
SAT NIGHT INTO MON...  
COLDER AIRMASS ASSOCIATED WITH THE ARCTIC VORTEX LOBE MENTIONED  
ABOVE SETTLES OVER NEW ENGLAND THROUGH THE PERIOD ALLOWING H92  
TEMPS TO DIP AS LOW AS ABOUT -12C BY MON MORNING. THIS SUGGESTS  
A PERIOD WITH BELOW NORMAL TEMPERATURES ONCE AGAIN, AS HIGHS  
WILL REMAIN IN THE 20S WITH LOWS IN THE SINGLE DIGITS AND LOW  
TEENS, COLDEST MON NIGHT THANKS TO RADIATIONAL COOLING SETUP.  
WHILE THE HIGH PRES AND STRONG SUBSIDENCE INVERSION IMPLIES  
MAINLY DRY CONDITIONS FOR MOST, ECHO THE PREVIOUS FORECASTERS  
CONCERNS FOR OCCASIONAL LIGHT SHSN ACROSS ESPECIALLY THE OUTER  
CAPE. N-NW FLOW SHOULD ALLOW ENOUGH FETCH GIVEN AT ITS COLDEST  
THE SST TO H85 DELTA T-VALUES SETTLE AROUND 15C. HOWEVER, THE  
STRONG SUBSIDENCE INVERSION MAY RESTRICT THE MIXED LAYER MAINLY  
BELOW H85, WITH THE STEEPEST LAPSE RATES IN DRIER AIR AND LITTLE  
TO NO MOISTURE IN THE DGZ, SO SNOWFALL RATES SHOULD REMAIN  
LIGHT. WILL CONTINUE TO HIGHLIGHT THIS RISK INTO THE DAYTIME ON  
MON, BEFORE THE TRAJECTORY SHIFTS.  
 
TUE INTO WED...  
AS UPPER LVL JET STREAK ROUNDS THE BASE OF THE DEVELOPED  
LONGWAVE TROF/CUTOFF ACROSS THE GREAT LAKES, THE SFC CLIPPER  
WILL BEGIN TO SHIFT INTO NEW ENGLAND. ENOUGH MOISTURE IN THE  
DGZ, COMBINED WITH THE MODEST CLIPPER LIFT SHOULD YIELD SOME  
SNOWFALL WIT THE ARRIVAL OF THIS FEATURE AS EARLY AS LATER TUE.  
HOWEVER, THERE IS SOME SUGGESTION OF A GRADUAL TILT TO THE  
LONGWAVE, ENHANCING THE LOWER LVL BAROCLINIC ZONE OFF THE COAST,  
WHICH MAY ALLOW FOR ENERGY TRANSFER IN THE FORM OF SECONDARY  
REDEVELOPMENT. ECMWF LEADS THE CHARGE HERE, AS IT DEEPENS AND  
TILTS THE TROF MORE SIGNIFICANTLY. WHILE THIS IS A TYPICAL BIAS,  
IT HAS BEEN MOST PERSISTENT WITH THIS THINKING. DUE TO THE  
FURTHER AMPLIFICATION, IT ALSO DELAYS THE PROCESS, POTENTIALLY  
YIELDING IMPACTS INTO EARLY THU. ENSEMBLE MEANS FROM THE ECENS  
AND GEFS DO SUPPORT THIS TO SOME EXTENT, BUT WITH OBVIOUS  
DEFERENCE TO SOME OF THE MORE PROGRESSIVE MEMBERS. WILL CONTINUE  
WITH THIS TIMING AND THERMAL PROFILES IN SUPPORT OF MAINLY SN  
(H92 TEMPS REMAIN BELOW -2C EVEN ON THE DETERMINISTIC ECMWF).  
WHILE CONFIDENCE CONTINUES TO RISE IN A PERIOD OF AT LEAST  
LIGHT-MODERATE SNOWFALL, THE AMPLIFICATION AND FINAL TILT WILL  
ULTIMATELY DETERMINE HOW STRONG AND HOW MUCH SNOW ULTIMATELY  
FALLS, SOMETHING THAT WILL BECOME BETTER RESOLVED AS THE ARCTIC  
WAVE BECOMES BETTER SAMPLED LATER THIS WEEKEND.  
 
THU INTO FRI...  
SHOULD THE ECMWF OR ENSEMBLE MEMBERS THAT SUPPORT THE MORE  
AMPLIFIED PATTERN BE CORRECT, IMPACTS FROM THE POTENTIAL  
SNOWSTORM COULD LINGER INTO THU. HOWEVER, AT THIS TIME, GIVEN  
THE OVERALL LACK OF CONFIDENCE DUE TO PROG VARIANCE WILL TREND  
TOWARD SOMEWHAT COLDER THAN NORMAL CONDITIONS GIVEN THE ARCTIC  
WAVE IS EXPECTED TO OPEN, MODERATE AND SHIFT OVER NEW ENGLAND.  
LOWER END POPS WILL COVER ANY PRECIP RISKS AT THIS TIME.
