.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ACROSS THE NORTH
COUNTRY THIS AFTERNOON...WITH A FEW STRONG STORMS POSSIBLE. THESE
STORMS WILL BE CAPABLE OF PRODUCE DIME SIZE HAIL AND LOCALIZED WIND
GUSTS TO 50 MPH...ALONG WITH FREQUENT CLOUD TO GROUND LIGHTING AND
BRIEF HEAVY DOWN POURS. TEMPERATURES WILL WARM INTO THE 70S TODAY
WITH A SOUTHERLY WIND SHIFTING TO THE NORTHWEST BY EVENING. ANOTHER
CHANCE FOR SHOWERS ARRIVES ON SATURDAY WITH ABOVE NORMAL

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 128 PM EDT FRIDAY...MINOR ADDL UPDATES AS OF EARLY
AFTERNOON...PRIMARILY TO LOWER MAX TEMPS BY A FEW DEGREES. REST OF
FCST IN GOOD SHAPE.

PRIOR LATE MORNING DISCUSSION...
MINOR UPDATE TO CLOUD COVER AND T/TD DATASETS AS OF LATE MORNING
BASED OFF LATEST OBSERVATIONS. A QUICK LOOK AT FORECAST/OBSERVED
SOUNDINGS AND MODEL PARAMETERS GIVE ME INCREASED CONFIDENCE THAT
CONVECTION TODAY WON'T GET TOO OUT OF HAND...MAINLY DUE TO VRB MID
LVL CLOUDS AND COOLER PBL TEMPS. WE MAY EVEN STRUGGLE TO REACH
CONVECTIVE TEMPS IN MANY AREAS...ESP AS INCOMING NAM SUGGESTS
CLOUDS/LIGHT SHOWERS ACT TO SUPPRESS PBL HEATING EVEN FURTHER.
WILL CONTINUE TO MONITOR...

&&

.SHORT TERM /8 PM THIS EVENING THROUGH 6 PM SATURDAY/...
AS OF 435 AM FRIDAY...CONVECTION WL QUICKLY DECREASE ACRS OUR CWA
THIS EVENING...AS S/W ENERGY SHIFTS EAST AND INSTABILITY
DISSIPATES. WL MENTION LOW CHC POPS FOR CENTRAL/EASTERN CWA THRU
02Z. OTHERWISE...EXPECT AREAS OF FOG TO DEVELOP...ESPECIALLY
LOCATIONS WHICH RECEIVED RAINFALL DURING FRIDAY AFTN. TEMPS WL
COOL INTO THE 40S MTNS AND 50S VALLEYS. FOR SATURDAY...A SHARP
MOISTURE GRADIENT DEVELOPS ACRS OUR CWA...ASSOCIATED WITH A
DEVELOPING WARM FRNT. WL PLACE THE HIGHEST POPS ACRS THE SOUTHERN
SLV INTO THE DACKS...WITH NIL POPS ACRS THE NEK. THIS WAA AND
ASSOCIATED SFC BOUNDARY AND ENERGY LOFT WL HAVE TO BE WATCHED
CLOSELY FOR A POTENTIAL SHIFT NORTH. THIS WOULD CARRY THE THREAT
FOR ADDITIONAL POPS INTO CENTRAL/NORTHERN VT AND ACRS MOST OF THE
DACKS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
AS OF 435 AM EDT FRIDAY...NORTHWEST FLOW ALOFT BECOMES RATHER PRONOUNCED
SATURDAY NIGHT WITH SURFACE HIGH PRESSURE BUILDING IN. THIS
SHOULD KEEP CONVECTIVE ACTIVITY SOUTH OF THE AREA AND THIS WILL BE
THE START OF A DRY PERIOD WITH UPPER RIDGE BUILDING INTO THE AREA
BEGINNING ON SUNDAY. WARM AIR ADVECTION AT 925/850MB DEVELOPS ON
SUNDAY AND HIGH TEMPERATURES WILL RANGE FROM THE MID 70S TO THE
LOWER 80S. THE WARM AIR ADVECTION BECOMES EVEN MORE PRONOUNCED ON
MONDAY AND TUESDAY WITH TEMPERATURES IN THE UPPER 70S TO MID 80S
EXPECTED. CLOUDS AND MOISTURE INCREASE ON TUESDAY AS UPPER RIDGE
MOVES EAST OF THE AREA AND AN UPPER LEVEL TROUGH OF LOW PRESSURE
APPROACHES FROM THE WEST. THE CHANCES FOR CONVECTION SHOULD
INCREASE LATE IN THE DAY TUESDAY OUT ACROSS THE SAINT LAWRENCE
VALLEY AND THEN ACROSS THE ENTIRE AREA TUESDAY NIGHT INTO
WEDNESDAY. UPPER TROUGH SHEAR APART AND LIFTS NORTHEAST WEDNESDAY
NIGHT INTO THURSDAY. THIS WILL KEEP THE AREA IN SOUTHWEST FLOW
ALOFT...SO WE WILL SEE HIGH TEMPERATURES AT OR SLIGHTLY ABOVE
SEASONAL NORMALS ALONG WITH THE POTENTIAL FOR SOME
CONVECTION...ESPECIALLY OVER OUR EASTERN AREAS.
