AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
406 AM EDT MON JUL 17 2006

.SYNOPSIS...A WEAK WEATHER DISTURBANCE ACROSS THE NORTHERN PART
OF THE STATE WILL MOVE EAST INTO NEW BRUNSWICK THIS MORNING. A
COLD FRONT WILL PRESS INTO QUEBEC LATER TODAY AND REACH NORTHERN
AREAS LATE TONIGHT. THE FRONT WILL MOVE ACROSS THE REGION ON
TUESDAY FOLLOWED BY HIGH PRESSURE FOR WEDNESDAY AND THURSDAY.

&&

.SHORT TERM /TODAY THROUGH TUESDAY/...
THE ONGOING CONVECTION MAINLY THROUGH THE NORTHERN AREAS AND THEN
CONVECTION ASSOCIATED WITH STRONG COLD FRONT MOVING THROUGH THE CWA
ON TUESDAY ARE THE MAIN CONCERNS FOR THE SHORT TERM.

WEAK SURFACE LOW ASSOCIATED WITH SHORT WAVE OVER THE SAINT
LAWRENCE VALLEY MOVING EASTWARD THROUGH WEAKLY DIFLUENT FLOW HAS
RESULTING IN ISOLATED/SCATTERED CONVECTION MAINLY THROUGH THE
NORTHERN ZONES EARLY THIS MORNING. AS THIS FEATURE MOVES EAST INTO
THE MARITIMES THIS MORNING...WEAK SHORT WAVE RIDGE SUPPORTING WARM
MID LEVEL THERMAL RIDGE MOVES INTO THE CWA THIS AFTERNOON. WILL
GRADUALLY LOWER POPS FOR THIS AFTERNOON BUT STILL HOLD ONTO A
SLIGHT CHANCE.

VERY WARM HUMID CONDITIONS PREVAIL ACROSS THE CWA WITH A RETURN OF
PATCHY FOG LATER TONIGHT. LATER TONIGHT...INSTABILITY INCREASES
AHEAD OF A STRONG COLD FRONT MOVING SOUTHEAST THROUGH QUEBEC
PROVINCE BENEATH HEIGHT FALLS ASSOCIATED WITH STRONGER MID LEVEL
TROUGH. BUFKIT SOUNDING PROFILES INDICATE CAPE VALUES INCREASING
TO AROUND 1000 J/KG ACROSS THE NORTH AND 1500 TO 2000 J/KG
DOWNEAST ALONG WITH LIS LOWERING TO AROUND MINUS FIVE. COOLING
MID LEVELS AND WARM SURFACE TEMPERATURES WILL ENHANCE LAPSE RATES
ALONG WITH RRQ OF 90+ KT JET SUPPORTING INCREASED LIFT AHEAD/ALONG
THE COLD FRONT TO DURING TUESDAY. BASED ON THIS STRONGER WINDS
ALOFT MAY ACCOMPANY THE CONVECTION AND SPC HAS INCLUDED THE CWA IN
A SLIGHT RISK FOR SEVERE THUNDERSTORMS WITH MAINLY STRONG WINDS
THE MAIN CONCERN ACCOMPANYING CONVECTION DURING TUESDAY.

MODELS CONTINUE TO INDICATE RAPID DRYING OF THE ATMOSPHERE IN WAKE
OF THE FRONT NORTHWEST TO SOUTHEAST ESPECIALLY DURING TUESDAY
AFTERNOON. WILL CONTINUE THIS THEME IN THE GRIDS.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...A COLD FRONT WILL PUSH
SOUTH OF THE AREA AND OUT TO SEA TUESDAY EVENING AS HIGH PRESSURE
BUILDS IN FROM QUEBEC. THIS HIGH WILL BRING DRIER AIR ALLOWING
TUESDAY NIGHT TO BE MAINLY CLEAR AND A BIT COOLER. HIGH PRESSURE
OVER THE AREA WEDNESDAY WILL BRING A DRY DAY WITH SUNSHINE MIXED
WITH A FEW CUMULUS CLOUDS. WEDNESDAY NIGHT WILL THEN TURN OUT
MAINLY CLEAR WITH SOME PATCHY VALLEY FOG BY MORNING. THE HIGH WILL
MOVE EAST ON THURSDAY ALLOWING INCREASINGLY HUMID AIR TO RETURN
FROM THE SOUTH SOUTHWEST. A STRONG COLD FRONT MAY THEN APPROACH
LATE THURSDAY NIGHT OR EARLY FRIDAY WITH THE POTENTIAL FOR SHOWERS
AND THUNDERSTORMS.

&&

.AVIATION...VFR CONDITIONS OVER THE NORTH WILL OCCASIONALLY LOWER
TO MVFR IN LOW CLOUDS EARLY THIS MORNING. THERE IS A POTENTIAL FOR
A THUNDERSTORM OVER NORTHERN AREAS EARLY THIS MORNING WHICH MAY
LOWER CONDITIONS TO IFR IN SOME AREAS. LIFR CONDITIONS IN LOW
CLOUDS AND FOG DOWNEAST ARE EXPECTED TO IMPROVE TO VFR DURING THE
MID MORNING HOURS. VFR CONDITIONS ARE EXPECTED ACROSS THE AREA
THIS AFTERNOON INTO EARLY THIS EVENING. FOG MAY REMAIN ALONG THE
COAST...AND WATCH FOR FOG TO RETURN TO INTERIOR DOWNEAST AREAS
LATER THIS EVENING.

&&

.MARINE...
SHORT TERM: WEAK FLOW REMAINS IN PLACE KEEPING WIND/SEAS BELOW SCA
CRITERIA THROUGH TONIGHT. SEAS APPROACH FIVE FEET AHEAD OF THE
FRONT DURING TUESDAY. WILL HOLD OFF ON ANY HEADLINES SINCE ITS A
THIRD PERIOD AND ALSO LOW CONFIDENCE IN WAVE WATCH GUIDANCE FOR
LATER TUESDAY.

LONG TERM: HIGH PRESSURE DOMINATES OVER THE WATERS KEEPING
WINDS/SEAS BELOW HEADLINE CRITERIA TUESDAY NIGHT INTO THURSDAY.
