High Wind in Maine, January 21, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
241 PM EST TUE JAN 21 2003

.SYNOPSIS...INTENSE LOW PRESSURE OVER THE MARITIMES WILL CONTINUE TO BRING
VERY COLD ARCTIC AIR ON STRONG WEST WINDS TONIGHT INTO WEDNESDAY...CREATING
DANGEROUS WIND CHILLS ACROSS ALL OF NORTHERN AND DOWNEAST MAINE. LIGHT SNOW
IS LIKELY WEDNESDAY NIGHT INTO THURSDAY MAINLY ACROSS THE NORTH AS MOISTURE
CIRCULATES BACK SOUTHWARD AROUND THE INTENSE LOW OVER THE MARITIMES. ANOTHER
LOW EXPECTED TO DEVELOP OFF THE MID ATLANTIC COAST WILL BRING A CHANCE OF
SNOW TO MAINLY DOWNEAST MAINE THURSDAY NIGHT AND FRIDAY.

DISCUSSION...TNGT AND WED: ALL MODELS INDICATE CONTINUING WIND ADVISORY WIND
SPEEDS OVERNIGHT. WINDS ACCOMPANIED BY FALLING TEMPS WHICH SHOULD EASILY
REACH THE -10S MOST LOCATIONS LATE TNGT WILL JUSTIFY EXPANDING THE WIND
CHILL WARNING TO THE COAST...WHICH WE PLAN ON KEEPING IN PLACE THROUGH WED
MORN. CLDS HAVE BEEN MUCH LESS THAN ANTICIPATED ACROSS THE N...SO WE WILL
INDICATE A GRADUAL INCREASE IN CLDS LATE TNGT INTO WED...MENTIONING
FLURRIES N ON WED AS THE BEGINNING OF MID LVL WARM ADVCN FROM THE MARITIMES
LOW WARM OCCLUSION BEGINS TO APPCH.

WED NGT AND THU: ALL GUIDANCE CONTINUES TO INDICATE INTENSE LOW PRESSURE
WILL REMAIN NEARLY STATIONARY OVER THE MARITIMES. AVN SOLUTION IS SHOWING
WARM AIR PIVOTING AROUND THE TOP OF THE LOW AND SETTING UP OVER-RUNNING FROM
WARM ADVECTION COMING DOWN FROM THE NORTH. THEREFORE...WE WILL CONTINUE TO
ADVERTISE POPS BOTH PDS WEIGHTING HIGHER LIKELY POPS ACROSS THE N WED NGT.

THU NGT AND FRI: WE NOTED  BIG DIFFERENCES BETWEEN THE ETA AND AVN FOR
THIS PTN OF THE FCST...WITH THE AVN INDICATING A DEFORMATION BAND OF CLDS/SN
SETTING UP OVR THE REGION...SPCLY DOWNEAST MAINE...AS LOW PRES ASSOCIATED
WITH A DIGGING S/WV FROM THE MIDWEST DEEPENS OFF THE MID ATLC COAST AND
TURNS NE TOWARD NEWFOUNDLAND. THE ETA KEEPS THIS SYSTEM...ALONG WITH ANY
MOISTURE WELL TO OUR S. WILL KEEP CONTINUITY FROM PREVIOUS FCST AND MENTION
OF CLDS AND BEST CHC OF SN ACROSS DOWNEAST MAINE THESE PDS.

EXTENDED: NEXT CHC OF SIGNIFICANT PRECIP WILL BE WITH TWO S/WVS HERALDING
WARM ADVCN AND MILDER TEMPS FROM THE WEST NEXT WEEK. THE FIRST SHOULD
ARRIVE LATE SUN INTO MON. THE NEXT SYSTEM SHOULD ARRIVE LATE DAY 7...
I.E...TUE NGT. MRF 1000-850 MB THICKNESSES OF GREATER THAN 1300 M FOR
DOWNEAST MAINE FOR THIS EVENT ARE NOT SUPPORTED BY THE OTHER EXTENDED
MODELS...SO WE KEPT PRECIP TYPE AS SN FOR THIS PD.

LEANED WITH A BLEND OF AVN AND MRF ENSEMBLE TEMP/POP MOS THROUGH THE
SHORT RANGE. OVERALL CONFIDENCE WITH THIS FCST UPDATE IS AVG.

COASTAL WATERS...WINDS NEVER CAME CLOSE TO STORM FORCE OVR OUR WATERS TDY.
LOOKING AT ETA BUFKIT PROGGED WIND PROFILES INDICATE STRONGER WINDS...IN
THE ORDER OF 45 TO 50 KT...WORKING DOWN THE SOUNDING TO 2000 FT ABV MSL
FROM 5000 FT LATER TNGT. THIS WOULD IMPLY WINDS INCREASING TO STRONG GALE
CATEGORY LATE TNGT INTO ERLY WED WITH POSSIBLE STORM FORCE WINDS...BUT
ATTM WE DO NOT BELIEVE WINDS SHOULD AVG STORM FORCE OVR THE WATERS FOR MORE
THAN AN HOUR OR TWO...SO WE WILL ADVERTISE STRONG GALES THRU WED MORN...
LESSER GALES LATE WED INTO WED NGT...DIMINSHING TO SCA ON THU AS THE MSL
PRES GRAD/LLVL COLD ADVCN WEAKENS.

.CAR...WIND CHILL WARNINGS TNGT AND WED MORN ALL ZONES.
       WIND ADVISORY (WORDING IN WIND CHILL WARNING) TONIGHT
       ZONES 1>6/10/11/15>17/29>32.
