DISCUSSION
KEY MESSAGE 1
INTO TONIGHT, YET ANOTHER SHORTWAVE SWINGS DOWN ALONG THE PERIPHERY
OF A MID LEVEL TROUGH CENTERED OVER THE WESTERN ATLANTIC.
ASSOCIATED SURFACE LOW PRESSURE AND COLD FRONT PUSH SOUTH THROUGH
NEW ENGLAND, BEFORE MOVING THROUGH LOCALLY TONIGHT. THE SYSTEM
IS MUCH LESS VIGOROUS THAN YESTERDAY'S COASTAL LOW, AND LIMITED
MOISTURE SHOULD PRECLUDE MOST FROM SEEING MUCH IN THE WAY OF
PRECIPITATION. BEST CHANCES FOR A FEW SHOWERS LOOK TO BE ACROSS
SE CT WHERE FORCING IS BEST, AND CAN'T RULE OUT A QUICK DOWNPOUR
OR TWO HERE WITH WEAK INSTABILITY. ELSEWHERE, A SPOTTY SHOWER IS
POSSIBLE, BUT COVERAGE LOOKS MUCH MORE WIDELY SCATTERED TO ISOLATED.
ANY RAIN SHOULD TAPER BY DAYBREAK OR SHORTLY THEREAFTER. GIVEN
A WEAK PRESSURE FIELD, WINDS REMAIN LIGHT.
METEOROLOGICAL SUMMER THEN KICKS OFF ON A RELATIVELY TRANQUIL NOTE
AS HIGH PRESSURE BUILDS SOUTH FROM CANADA. A FEW DIURNALLY DRIVEN
SHOWERS REMAIN POSSIBLE MONDAY AFTERNOON, MAINLY ACROSS INTERIOR
S CT, GIVEN A BIT STEEPER LAPSE RATES WITH THE COLD POOL OVERHEAD.
OTHERWISE, DRY, COMFORTABLE CONDITIONS PREVAIL WITH TEMPERATURES
TOPPING OUT IN THE LOW TO MID 70S, OR NEAR CLIMO FOR THE START
OF JUNE.
KEY MESSAGE 2
THE COMBINATION OF AN INCREASING SW WIND AND AN E SWELL
OF 3-4 FEET AT 10S FROM DEPARTING LOW PRESSURE WILL RESULT IN A
MODERATE RISK FOR ALL AREAS TODAY. THE MODERATE RISK CONTINUES ON
MONDAY WITH AN E/SE FLOW PICKING UP TO 10-15 KTS COMBINED WITH
A SOUTHERLY SWELL. MONDAY IS CLOSER TO A HIGHER END LOW/LOWER END
MODERATE, BUT RCMOS WAS SHOWING MODERATE FOR ALL BEACHES, SO
CONTINUED TO STICK WITH THAT. THE RISK FINALLY LOWERS TO LOW FOR
TUESDAY WITH A S WIND UNDER 10 KT AND 2-3 FT 5-7S SWELL OUT OF THE E.
KEY MESSAGE 3
BY MIDWEEK, SURFACE HIGH PRESSURE DROPS FROM HUDSON BAY DOWN INTO
THE GREAT LAKES AS RIDGING ALOFT AMPLIFIES OVER THE CENTRAL US.
THIS RIDGE GRADUALLY BUILDS EAST INTO THE REGION THROUGH LATE WEEK,
PROMOTING RISING TEMPERATURES WITH IT.

REMAINS IN PLACE THROUGH AT LEAST EARLY NEXT WEEK.
