What happened

The episode as NWS CAR wrote it up.

An area of low pressure rapidly intensified while tracking from the southeastern states to the southern New England coast from the 15th to the 16th. A tight pressure gradient developed between the low and high pressure centered over eastern Canada which also blocked the northern movement of the low. The intense low slowly drifted east from the 16th through the 19th while high pressure remained across eastern Canada. The storm had many impacts on the region including strong damaging winds...heavy rain with urban and small stream flooding and coastal tidal flooding. These impacts were most significant across Downeast areas...particularly near the coast. In addition...the storm brought locally heavy snow to some higher elevations of northern and northwest Maine.|The tight pressure gradient supported strong east to northeast winds across mostly central and Downeast portions of the region through the 16th and 17th. Disturbances rotating around the main low contributed to several surges of strong winds over the course of the event. Winds gradually diminished during the 18th and 19th...though gusty winds still lingered during this time particularly near the Downeast coast.|Damaging winds occurred across all of Downeast Maine...particularly near the coast where some wind gusts exceeded 70 mph. Damaging winds extended inland to central Piscataquis...central Penobscot and northern Washington counties. The combination of strong winds and saturated ground from the heavy rains which accompanied the storm and the spring thaw contributed to the uprooting of numerous trees with many other trees snapped and broken. Several trees fell on structures and vehicles causing damage. Other trees and branches brought down powerlines when they fell...with power poles also snapped and toppled due to the strong winds which contributed to thousands of power outages. Fallen trees and power lines also blocked roads.|The combination of astronomical high tides...amongst the highest of the year...along with persistent strong onshore winds and large waves contributed to coastal flooding during high tide cycles starting on the evening of the 16th and continuing through the evening of the 19th. During high tides...overwash flooded some coastal roads resulting in road closures. Debris was washed onto roads with some roads also damaged. A causeway connecting the mainland with Deer Isle was closed several times during the event due to overwash and flooding.|The storm also brought heavy rain to the region. The heaviest rains occurred across central and Downeast areas...along with the favored upslope areas of Piscataquis county. Rainfall totals across central and Downeast areas generally ranged from 2.50 to 4.00 inches...with local totals in excess of 5.00 inches. Across Piscataquis county...rainfall totals generally ranged from 2.50 to 4.00 inches with local totals approaching 5.00 inches. The heavy rain contributed to rapid rises on smaller rivers and streams across the region some of which overflowed onto surrounding low land areas. The small river and stream flooding caused some road closures. Urban and poor drainage flooding also occurred which led to additional road closures and contributed to basement flooding. Mainstem rivers also rose during this time but crested below flood stage.|Enough cold air was in place to support an interval of heavy snow during the early stages of the event across the higher terrain of Piscataquis county and northern Somerset county. Snowfall totals across some higher terrain areas ranged from 8 to 12 inches...with local totals in excess of 12 inches. Lesser snow acumulations occurred at lower elevations.

INTENSE LOW PRESSURE JUST EAST OF THE MARYLAND COAST WILL
MOVE TO NEAR NEW YORK CITY BY EARLY MONDAY BEFORE BECOMING
NEARLY STATIONARY LATE MONDAY INTO TUESDAY. A WIDE VARIETY OF
PRECIPITATION...RANGING FORM LOCALLY HEAVY WET SNOW OVER THE
HIGHER ELEVATIONS OF WESTERN MAINE TO LOCALLY HEAVY RAINFALL
ACROSS DOWNEAST...WILL SPREAD OVER THE REGION OVERNIGHT AND
CONTINUE INTO TUESDAY. VERY STRONG WINDS ARE ALSO EXPECTED
FROM THIS STORM ESPECIALLY OVER CENTRAL AND DOWNEAST MAINE.
&&

.NEAR TERM /THROUGH MONDAY/...
NO SIGNIFICANT CHANGES FROM THE PREVIOUS FORECAST THIS AFTERNOON.
SURPRISE TO SEE THE GFS LOWER QPF AMOUNTS SO USED A BLEND OF THE
NAM/GFS/HPC FOR FINAL AMOUNTS. THROUGH TUESDAY AFTERNOON EXPECT 3
TO 4 INCHES OF LIQUID ACROSS DOWNEAST WITH 2 TO 3 INCHES THROUGH
CENTRAL MAINE AND 1 T 2 INCHES ACROSS NORTHERN SECTIONS. SNOWFALL
AMOUNTS STILL LOOK GOOD WITH OVER A FOOT FOR WESTERN MTNS, 3 T0 5
INCHES IN THE FOOTHILLS AND OVER NORTHEAST SECTIONS WITH A COUPLE
OF INCHES FOR THE BANGOR AREA. EXTENDED COASTAL FLOOD WATCH INTO
WASHINGTON COUNTY FOR MONDAY AS STORM SURGE OF 1 TO 2 FEET MAY
CAUSE SOME FLOODING OF PIERS AND LOW LYING AREAS. HEAVY WET SNOW
WILL PRODUCE A HIGH IMPACT OVER THE MOUNTAINS WITH A MIXTURE OF
SNOW AND RAIN ELSEWHERE PRODUCING A SLUSHY MESS. STRONG EASTERLY
WINDS WILL IMPACT DOWNEAST AND CENTRAL SECTIONS AFTER MIDNIGHT AND
MOST OF THE DAY ON MONDAY. WITH UNFROZEN GROUND WINDS MAY KNOCK
DOWN TREES AND POWER LINES PRODUCING POWER OUTAGES.
&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
TRIED TO STAY THE COURSE W/THIS SYSTEM. BLENDED THINGS IN ESP FOR
THE QPF & TEMPERATURES. ALL MEDIUM RANGE GUIDANCE COMING IN LINE
WITH INTENSE LOW PULLING SLOWLY ESE AWAY FROM THE AREA. LARGE ESE
FETCH WILL CONTINUE TO BRING DECENT AMOUNTS OF PRECIP INTO THE CWA
RIGHT INTO TUESDAY EVENING AND THEN THINGS START SHIFTING TO THE
SSE BY WEDNESDAY AND BEST FORCING SHIFTING ESE.

AFTER BLEND GUIDANCE W/HPC...ADDITIONAL PRECIP AMOUNTS BY WEDNESDAY
COULD EASILY HIT 1 TO 3 INCH AMOUNTS W/THE HIGHEST AMOUNTS ACROSS
DOWNEAST AND ERN SECTIONS AND UPSLOPE FAVORED REGIONS SUCH AS THE
CENTRAL HIGHLANDS. MUCH OF THIS SHOULD BE IN THE LIQUID FORM W/THE
EXCEPTION FOR THE FAR N & NWRN AREAS AND HIGHER ELEVATIONS WHERE
SNOW WILL OCCUR ESP MONDAY NIGHT AGAIN TUESDAY NIGHT W/DYNAMIC
COOLING OCCURRING. SNOW GRID FOR MONDAY NIGHT PLAYS FOR THIS
THINKING W/1-3 INCHES BACK ACROSS THE FAR N & WRN AREAS. NOT
CHANGE WAS MADE TO TEMPS FOR CONTINUITY PURPOSES.

DECIDED TO HANG ONTO STRONG WIND GUSTS RIGHT INTO TUESDAY AS PRES
GRADIENT REMAINS TIGHT. MOMENTUM TRANSFER FROM THE BUFKIT SUPPORTS
THIS AS WELL. WOULD NOT BE SURPRISED TO SEE AT LEAST ADVISORY
CONDITIONS INTO TUESDAY.

AS FAR AS CONTINUED FLOOD CONCERNS...SEE HYDROLOGY SECTION BELOW.
&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
BASICALLY USED THE HPC GRIDS WHICH FOLLOWED THE ECMWF. COLD
PATTERN FINALLY BREAKS AS LOW PRESSURE FINALLY SLIDES SOUTHEAST OF
THE AREA. HIGH PRESSURE NORTHWEST OF THE AREA WILL PRODUCE A DRY
NORTHERLY FLOW ACROSS THE AREA WITH ABOVE NORMAL TEMPERATURES.
&&

.AVIATION /02Z MONDAY THROUGH FRIDAY/...
VFR CONDITIONS WILL GRADUALLY LOWER TO MVFR AND IFR FROM SOUTH TO
NORTH THE NEXT 24 HOURS. EXPECT MVFR CIGS WITH RAIN/SNOW SHOWERS
WEDNESDAY AND WEDNESDAY NIGHT THEN VFR CONDITIONS FOR THURSDAY AND
FRIDAY.
&&

.MARINE...
980 MB LOW JUST EAST OF THE MARYLAND COAST CONTINUES TO DEEPEN
WITH THE NORTHERN EDGE OF THE PRESSURE GRADIENT STARTING TO
APPROACH THE COASTAL WATERS. HAVE INCREASE SUSTAINED/GUSTS A
CATEGORY AS EXPECT WIND GUSTS TO APPROACH NEAR HURRICANE FORCE AT
TIMES LATE TONIGHT AND MONDAY.

CONTINUED W/STORM FORCE WINDS MAINLY W/THE GUSTS MON NIGHT INTO
TUE. COORD WAS DONE W/GYX AND OPC. LOOKS LIKE THINGS FINALLY DROP
OFF AS LOW FILLS AND PULLS AWAY LATE WED.
&&

.HYDROLOGY...
ADDED N PENOBSCOT AND S AROOSTOOK TO WATCH DUE TO AMPLIFIED LIQUID
PCPN THERE. FEEL THAT THE HEADWATERS OF THE PISCATAQUIS AND
PENOBSCOT NORTH WILL SEE THE MAJORITY OF THERE PCPN AS SNOW...SO
DID NOT ADD N PISCATAQUIS OR AROOSTOOK TO WATCH. PROBLEMS IN THE
WATCH AREA SHOULD BE CONTAINED TO SMALL BROOKS...STREAMS AND URBAN
TYPE ISSUES. WILL HAVE TO KEEP AN EYE ON P TYPE IN THE HEADWATERS
OF THE PISCATAQUIS AS MORE LIQUID THERE COULD CAUSE MAINSTEM
ISSUES FROM BLANCHARD TO MEDFORD.
