AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
322 AM EDT THU JUL 27 2006

.SYNOPSIS...A SERIES OF UPPER LEVEL TROUGHS CROSSING THE REGION
WILL PRODUCE SHOWERS AND THUNDERSTORMS TODAY AND FRIDAY. A COLD
FRONT WILL CROSS THE STATE ON SATURDAY BRINGING RELIEF FROM THE
WARM AND MUGGY WEATHER AS CANADIAN HIGH PRESSURE BUILDS OVER NEW
ENGLAND SUNDAY AND MONDAY.

&&

.SHORT TERM /TODAY THROUGH FRIDAY/...
MAIN FOCUS WILL BE SVR WX & FLASH FLOOD POTENTIAL. SPC HAS THE CWA
W/THE EXCEPTION OF THE COAST IN A SLGT RISK FOR SVR WX FOR TODAY.
MAIN THREAT LOOKS TO BE DAMAGING WINDS. COLLABORATED W/SPC & GYX.
GYX...WE WOULD APPRECIATE ANY INFORMATION YOU CAN PASS ON TODAY IN
REGARDS TO CELLS THAT YOU SEE ON YOUR RADAR.

USED A MODEL BLEND APCH W/THE POPS/SKY & TEMP GRIDS THROUGH
TONIGHT & THEN USED THEGFS FOR FRIDAY. GFS APPEARS TO BE
HANDLING THINGS WELL PER LATEST REGIONAL RADAR & IR/WV SATL
IMAGERY. WEAK FRONTAL BOUNDARY HANGING OVER THE CWA COUPLED
W/UPPER TROF APCHG FROM QUEBEC TODAY WILL HELP TO GET THINGS
GOING. ST & FOG THIS MORNING WILL QUICKLY BURN OFF W/THE HELP OF
THE SUN AIDING IN DESTABLIZATION. NICE JET LET BETWEEN H8 & H7
(AROUND 35 KTS) TO MOVE THROUGH THE NRN & CNTL PORTION OF THE CWA
THIS AFTERNOON. BUFKIT & TOOLKIT SOUNDINGS SHOW CAPES TO HIT 1000+
J/KG FOR NRN & CNTL CWA W/KIS INTO THE MID 30S & PWS RUNNING 1.5+
INCHES. DEEP LAYER SHEAR IS EVIDENT THROUGH 6 KM POINTING TO
DAMAGING WIND POTENTIAL. HIGH WBZS & FRZG LVLS WILL LIMIT HAIL
THREAT. THAT IS NOT SAYING THAT HAIL IS NOT POSSIBLE IF 60 DBZ
CORE CAN PUNCH THROUGH -20C LAYER. POTENTIAL FOR CELLS TRAINING
OVER THE SAME AREAS WILL LEAD TO FLASH FLOOD THREAT AS WELL.
BEEFED UP WORDING IN THE GRIDS & ZPF TO REFLECT STRONG WINDS & HVY
RAFL. HWO WILL BE ENHANCED AS WELL.

CONVECTION SHOULD WIND DOWN THIS EVENING AS UPPER TROF PUSHES
INTO NEW BRUNSWICK. KEPT CHC POPS ALONG ERN 3RD OF THE CWA
OVERNIGHT. ADDED AREAS OF FOG AGAIN TONIGHT W/LLVLS MOIST & THE
POTENTIAL FOR SOME PARTIAL CLEARING. HUMID NIGHT W/DEWPOINTS
REMAINING WELL INTO THE 60S.

ANOTHER ROUND OF CONVECTION SET TO GO ON FRIDAY AS SFC TROF &
UPPER LVL SUPPORT MOVE INTO THE REGION FROM THE W. USED THE GFS
TIMING & PLACEMENT & THEN MODIFIED THE POP GRIDS ACCORDINGLY. WENT
W/WARMER TEMPERATURES W/80+ CWA WIDE W/THE EXCEPTION OF THE COAST
THANKS TO SEA BREEZE INTERACTION.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
UPPER TROUGH WILL MOVE EAST OF THE REGION FRIDAY NIGHT WITH
SHOWERS AND THUNDERSTORMS MOVING SOUTHEAST OF THE AREA. A COLD
FRONT WILL CROSS THE STATE ON SATURDAY. BOTH GFS AND NAM INDICATE
A DRY FRONTAL PASSAGE WITH LIMITED MOISTURE BUT WILL MENTION AT
LEAST A SLIGHT CHANCE IN THE GRIDS SINCE FRONT CROSSES THE STATE
IN THE AFTERNOON. CANADIAN HIGH PRESSURE BUILDS ACROSS THE REGION
SUNDAY INTO MONDAY BRINGING RELIEF FROM THE WARM AND MUGGY WEATHER.

&&

.AVIATION...
WITH PLENTY OF LOW LEVEL MOISTURE...MVFR CIGS AND VSBY AT ALL
SITES THIS MORNING WITH IFR POSSIBLE AT KBGR. STRATUS AND FOG WILL

EXPECT STRATUS AND FOG TO REDEVELOP LATER TONIGHT.

TONIGHT & THEN SLIGHT INC IN THE GRADIENT WILL BRING SPEEDS UP TO
15 KTS ON FRI.

LONG TERM: SOUTHWEST FLOW BELOW 15 KT FRIDAY NIGHT WILL TRANSITION
