NortheastPAWx Posted October 27, 2012 Author Share Posted October 27, 2012 Rainfall amounts backing off a bit on modeling...seeing 4" at most this morning, some areas near 5". NVM, end of the run tacks on the rest of the precip. Link to comment Share on other sites More sharing options...
JamieOber Posted October 27, 2012 Share Posted October 27, 2012 Well guys how does GFS look? To me it looks really intense and gets a lot of us northeast of the center....however I am terrible at interpreting maps lol. Those of us who have power will see some intense images out of NYC if that happens. Link to comment Share on other sites More sharing options...
Santa Clause Posted October 27, 2012 Share Posted October 27, 2012 Quiet in here....lol. Here is my first guess. Widespread 25 to 35 mph sustained winds...gusts to 50-55. Heavy rains of 3 to 6 inches, with localized flooding on some creeks and streams. Link to comment Share on other sites More sharing options...

NeffsvilleWx Posted October 27, 2012 Share Posted October 27, 2012 Upside of being a renter outside of a flood plain....lol lol one of many upsides. I spent the morning at the grocery store (it was PACKED, and absolutely NO water on the shelves), then filled a propane tank, mowed, cleaned out gutters, secured lawn ornaments/furniture. Also visited one of our dogs at the vet. He was admitted to the pet ER last night, he's doing much better today, hope to bring him home tomorrow.

djr5001 Posted October 27, 2012 Share Posted October 27, 2012 Looking at some of the models - no offense to Zak, but I think the 6"+ is way overdone. cannot rely on model precip output... in convective bands it doesnt take much to surpass what the models projected... take early last september for example... very strong PWAT anomaly flowing into eastern PA but models were not predicting the 1-2"+/hr rainfall rates we ended up with before the flooding started...

djr5001 Posted October 27, 2012 Share Posted October 27, 2012 latest AFD... .LONG TERM /MONDAY THROUGH SATURDAY/... AFTERWARD...THE WAITING GAME NEARS ITS GRAND FINALE /WITH RESPECT TO SANDY'S HEAVY RAIN AND LANDFALL LOCATION/ AS SHE BEGINS HER NORTHWEST CURL TOWARD THE MID ATLANTIC SEABOARD FROM THE WARM GULF STREAM WATERS VERY EARLY MONDAY MORNING. A LARGE SWATH OF INCREASINGLY HEAVY RAIN WILL SPREAD NNWD WELL AHEAD OF SANDY...AND INTO THE SOUTHEASTERN PART OF THE CWA LATE SUNDAY NIGHT...BEFORE EXPANDING INTO THE CENTRAL PA ZONES ON MONDAY. LATEST 00Z-06Z MODEL GUIDANCE CONTINUES TO TIGHTEN UP THE RANGE OF POSSIBLE LANDFALL LOCATIONS...WITH THE MEAN NOW BEING BETWEEN ATLANTIC CITY NEW JERSEY...AND OCEAN CITY MARYLAND MONDAY EVENING. THIS PATH IS VERY OMINOUS FOR THE LARGE POPULATION AREA OF SOUTHEASTERN PA AND THE LOWER SUSQ VALLEY...WITH BANDS OF SQUALLS CONTAINING EXCESSIVE RAINFALL AND STRONG DAMAGING WIND GUSTS IMPACTING THE REGION. TO COMPLICATE MATTERS...THERE WILL ALSO LIKELY BE A SEVERE WEATHER/TORNADO THREAT NEAR...AND TO THE NORTH OF THE KLNS AND KMDT AREAS LATER MONDAY NIGHT. WIND FIELDS SURROUNDING THE LOW CENTER WILL BE VERY IMPRESSIVE MONDAY INTO TUESDAY AS SANDY TAKES A LIKELY TRACK WWD INTO CENTRAL OR SOUTHERN PENN. NORTHEAST TO NW WINDS OF 60 PLUS KTS ARE FCST TO BE ONLY ABOUT 2 KFT AGL...WITH THE 50 KT CONTOUR AT 1 KFT AGL. THESE WINDS WILL EASILY BE MIXED DOWN TO THE SFC BY THE HEAVY RAIN-BANDS...BUT LIKELY MOST SEVERELY IMPACT THE HIGHER TERRAIN OF THE SOUTH AND EAST...BEFORE BECOMING SLIGHTLY DAMPENED TWD THE CENTRAL MTNS. HEAVIER QUASI-SPIRAL RAIN BANDS WILL EASILY MIX OUT OCNL GUSTS AROUND 50KTS SHOULD THIS EXPECTED MODEL MEAN TRACK /AND TPCS/ VERIFY. WE POSTED A FLOOD WATCH FOR THE SE ZONES A SHORT TIME AGO...AND IT WILL RUN FROM 06Z MONDAY THROUGH 00Z WED...WITH 4 INCHES OF MORE LOOKING LIKE A GOOD POTENTIAL. LOCALIZED MUCH HEAVIER AMOUNTS OF 6-10 INCHES ARE ALSO WITHIN THE REALM OF POSSIBILITIES AS THE HYBRID STORM IN CAPTURED...THEN ABSORBED BY THE AMPLIFYING AND STRONGLY NEG TILT UPPER TROUGH. IN ADDITION TO THE PLETHORA OF PROBLEMS RELATED TO WIND...RAIN AND POTENTIAL SEVERE CONVECTION...THE POTENTIAL FOR SEVERAL INCHES OF HEAVY WET SNOW STILL REMAINS FOR THE RIDGES OF THE LAUREL HIGHLANDS BEGINNING LATE MONDAY OR MONDAY NIGHT...AND CONTINUING THROUGH TUESDAY AS THE 850 MB WET BULB TEMPS COOL TO JUST UNDER 0C FROM THE SOUTHWEST. MUCH HEAVIER SNOW IS EXPECTED FURTHER SOUTH ACROSS THE MTNS OF WVA. SANDY AND THE UPPER TROUGH CAPTURING IT FROM THE WEST...EVOLVE INTO A LARGE/STACKED LOW ACROSS THE NRN VIRGINIAS OR CENTRAL PENN TUESDAY BEFORE GRADUALLY FILLING AND DRIFTING NNE DURING THE MIDWEEK. SCATTERED TO NUMEROUS RAIN SHOWERS...MIXED WITH SOME WET SNOW ACROSS THE RIDGES WILL FOLLOW FOR THE MID-WEEK/HALLOWEEN PERIOD. Link to comment Share on other sites More sharing options...

EasternUSWX Posted October 27, 2012 Share Posted October 27, 2012 Looking at some of the models - no offense to Zak, but I think the 6"+ is way overdone. No way.

Blizzard92 Posted October 27, 2012 Share Posted October 27, 2012 No way. This is a tropical system, which usually over produce compared to the models. I agree, with PWATs near +3SD given the time of year in association with the system's tropical origins, I would anticipate possible localized rain totals exceeding 10in in parts of southern and eastern Pennsylvania. The long duration of the event will also make this threat a higher likelihood. Mesoscale banding cannot be picked up on operational global models, so that is where people are getting confused when analyzing QPF. Link to comment Share on other sites More sharing options...
canderson Posted October 27, 2012 Share Posted October 27, 2012 T minus 48 hours until crap hits the fan. My parents got to town last night and have tickets to fly out!onday at noon.

JamieOber Posted October 27, 2012 Share Posted October 27, 2012 I mean wind speed wise...I was right on. Gusts over 60? Probably be a few of those reports around here. The worst part of this is you really don't need that high winds to cause a lot of problems with the saturated ground. We lost a tree down at the end of our property last September in like 40 mph winds due to the ground being so wet. OT, it's still alive, believe it or not. Part of its roots system must still be attached. It's down in the wooded end so we don't care. Link to comment Share on other sites More sharing options...
Eskimo Joe Posted October 27, 2012 Share Posted October 27, 2012 Looking at some of the models - no offense to Zak, but I think the 6"+ is way overdone. I tend to disagree with you. The structure of the storm, the moisture feed and jet stream alignment will make Sandy a highly efficient rain producer. Also, the storm will be lingering over Central PA for 18 - 22 hours so whoever gets under that stalled western flank of heavy rain is going to get soaked.
