1032 AM EDT SAT JUL 1 2006

.SHORT TERM /REST OF TODAY/...
VISIBLE SATELLITE LOOP SHOWING AREA OF CU ALONG A WEAK BOUNDARY ACROSS
NORTHERN NEW YORK AND NORTHERN VERMONT AT THIS TIME...WITH COMPOSITE
RADAR LOOP SHOWING SOME WIDELY SCATTERED SHOWERS DEVELOPING ACROSS
SAINT LAWRENCE AND FRANKLIN COUNTIES IN NORTHERN NEW YORK AT THIS
TIME AS WELL. BUFKIT SOUNDINGS SHOW STEEP LOW LEVEL LAPSE RATES
ACROSS NORTHERN NEW YORK AND NORTHERN VERMONT THIS AFTERNOON...SO WILL
UPDATE THE ZONE FORECASTS AND GO WITH A 20 PERCENT CHANCE OF A
SHOWER OR THUNDERSTORM FOR TODAY. WILL ALSO MAKE SOME MINOR
TWEEKS TO WIND SPEEDS ANDS DIRECTIONS IN THE ZONES AS WELL.
OTHERWISE...NO CHANGES TO THE REMAINDER OF THE FORECAST AT THIS TIME.
&&

.PREV DISCUSSION...
 /ISSUED 408 AM EDT SAT JUL 1 2006/

SHORT TERM /TODAY THROUGH MONDAY NIGHT/...
ACTIVE SHORT TERM WX PATTERN CONTINUES ACROSS THE NORTH COUNTRY OVER
COURSE OF NEXT 36 HOURS...AS WEAK HIGH PRESSURE GIVES WAY TO
AMPLIFIED AND HIGHLY DYNAMIC SYSTEM APPROACHING FROM GREAT LAKES
TONIGHT. LATEST SYNOPTIC MAP PLACES WEAK/FLAT RIDGING FROM SFC TO
MID LVLS ACROSS NERN QUARTER OF NATION AT THIS HOUR W/MAINLY CLR TO
PC CONDS AREA WIDE. AN ISOLD SHOWER OR TWO HAS DEVELOPED ACROSS NRN
NY EARLY THIS MORNING...BUT NOT EXPECTING ANY ADDL DEVELOPMENT
THROUGH SUNRISE. SFC TROUGH NORTH OF SLV ACROSS SC ONTARIO/QUEBEC
DRIFTING SLOWLY SOUTH AT THIS HOUR...AND EXPECT THIS FEATURE TO LIMP
SLOWLY SOUTH TODAY AND BECOME STATIONARY JUST NORTH OF BORDER LATER
TODAY BEFORE LIFTING NORTHWARD AS A WARM FRONT OVERNIGHT. MODELS
STILL HINTING AT WDLY SCT CONVECTION ALONG THIS BNDRY FROM A
CYOW-CYUL-CYSC LINE LATER THIS AFTERNOON AND SEE NO REASON TO
DISCOUNT THIS SCENARIO ATTM AS AT LEAST SOME MOISTURE CONVERGENCE
AND INSTABILITY STILL EVIDENT IN MODEL SOUNDINGS/PROGS. CANNOT
COMPLETELY RULE OUT A STRAY SHOWER OR STORM ALONG NORTHERN BORDER
LATER TODAY...BUT WILL LEAN CLOSER TO GFS SOLN AT THIS POINT AND
PRECLUDE MENTION OF ANY PCPN. AMPLE BNDRY LYR MIXING TO ABOVE 850
HPA LVL ALONG W/MEAN 850 HPA TEMPS IN THE 12-14C RANGE ARGUE FOR A
NICE REBOUND TO SUMMERTIME TEMPS TODAY...WITH MANY LOCALES CLIMBING
INTO THE 80S UNDER AMPLE SUN.

GENERAL WX THEN BECOMES RATHER CONCERNING LATER TONIGHT..ESP
NORTHERN NEW YORK AS AFOREMENTIONED WARM FRONT LIFTS NORTH INTO
CANADA AND POTENTIAL CONVECTIVE COMPLEX PUSHES EASTWARD FROM GREAT
LAKES STATES OVERNIGHT. DESPITE STABLE LOWER NOCTURNAL BNDRY
LYR...TREMENDOUS LL JET MAX FROM 45 TO 55KT FROM 2-3KFT SURGES INTO
NRN NY...ESP SLV AFTER 06Z ABOVE SHALLOW INVERSION (ONLY 1KFT) AS
PCPN APPROACHES. NOT FULLY CONFIDENT THAT ANY OF THESE SPEEDS WILL
MIX DOWN...BUT DUE TO STRENGTH OF JET...AND POSSIBILITY THAT
CONVECTION WILL OCCUR (NEG SHOWALTER INDICES)...WILL OPT FOR
ENHANCED WORDING IN ANY STORMS ACROSS WRN PORTIONS OF NRN
NY...MAINLY SLV/WRN DACKS LATER TONIGHT. FURTHER EAST...DEEPER
NOCTURNAL BNDRY LYR AND WEAKENING TREND OF CONVECTION SHOULD
PRECLUDE ANY MENTION OF STRONG STORMS.

BY SUNDAY...ENTIRE FA IN WARM SECTOR OF IMPRESSIVE AUTUMN LIKE
SYSTEM RACING ACROSS SRN ONTARIO/QUEBEC. AMPLE SHEAR PARAMETERS
COMBINED W/SFC BASED INSTABILITY AND WARM BNDRY LYR CONDS ARGUE FOR
ADDL STRONG CONVECTIVE ACTIVITY ACROSS MUCH OF AREA. BEST FORCING TO
OCCUR ACROSS THE NORTH THROUGH EARLY AFTERNOON...AND ACROSS THE
SOUTH FROM MID TO LATE AFTERNOON HOURS. SOUNDING PROFILES WOULD
SUGGEST BOTH STRONG WIND AND LARGE HAIL (LOWER WBZ HEIGHTS) POTL
EXISTS W/STRONGER CELLS.

AFTERWARDS...MAINLY CLEAR AND SEASONABLY COOL SUNDAY NIGHT AS
FRONTAL BNDRY SAGS SOUTHWARD INTO SRN NEW ENGLAND...THEN MAINLY
SUNNY/PC AND SEASONABLY WARM FOR MONDAY AS SHORTWAVE RIDGING AFFECTS
REGION. SOME HINTS THAT ADDL SHORTWAVE ENERGY MAY AFFECT FA LATER
MONDAY NIGHT (AFTER MIDNIGHT) W/ADDL CONVECTIVE ACTIVITY. THIS
FEATURE APPEARS RATHER INNOCUOUS PER MODEL SOUNDINGS/DYNAMICS...BUT
WITH INHERITED FCST ALREADY HAVING MENTION OF PCPN FOR THIS
PERIOD...SEE NO REASON TO DISCOUNT ATTM.

LONG TERM /TUESDAY THROUGH FRIDAY/...
NO CHGS TO EXTENDED PORTIONS OF FCST ATTM. LATEST OPERATIONAL SOLNS
ADVERTISE BROAD SW FLOW FROM SFC TO ALOFT THROUGH MOST OF THE PERIOD
AS LARGE UPPER TROUGH/CLOSED LOW DUMBBELL SLOWLY SOUTHWARD ACROSS NE
CONUS. RATHER MOIST BNDRY LYR CONDS COMBINED WITH AVBL DYNAMICS WILL
ARGUE FOR A CONTINUED CHC OF MAINLY AFTERNOON/EARLY EVE CONVECTION
MOST DAYS...WITH BEST CHC OF DRY WEATHER WOULD APPEARING TO COME BY
LATER WED INTO WED NT AS FLOW INITIALLY BACKS. TEMPS TO REMAIN NEAR
SEASONAL EARLY JULY NORMS...PERHAPS SLIGHTLY BLW NORMAL ON A FEW
DAYS DUE TO MORE CLOUD COVER.

AVIATION...
FEW CLOUDS ARE EXPECTED ACROSS THE AREA THIS MORNING AND AFTERNOON
RESULTING IN VFR CONDITIONS. THE ONLY EXCEPTION TO THIS WILL BE
BETWEEN 08Z AND 12Z WHERE AREAS OF LOW CLOUDS AND FOG CAN BE
EXPECTED...ESPECIALLY AT KSLK AND KMPV.  THIS WILL RESULT IN A
PERIOD OF IFR AND LIFR CONDITIONS AT THESE LOCATIONS.  WINDS WILL BE
INCREASING FROM THE SOUTH AND SOUTHWEST TODAY WITH HIGHER GUSTS IN
THE LARGER VALLEYS LATER TODAY AND TONIGHT.  NO PRECIPITATION IS
EXPECTED THROUGH THIS PERIOD...BUT SHOWERS AND THUNDERSTORMS WILL
BEGIN TO MOVE INTO NORTHERN NEW YORK AFTER 06Z TONIGHT.
