SCATTERED CONVECTION WL DECREASE AS SFC INSTABILITY DISSIPATES.
WL MENTION LOW CHC POPS THRU THE EVENING HRS...THEN PATCHY FOG WL

SOUTHERLY FLW AT MID LVLS DEVELOPING BY MONDAY. THIS WL SHIFT OUR
MID LVL FLW FROM SW TO SOUTHERLY AND ADVECT DEEPER MOISTURE BACK
INTO OUR CWA BY MONDAY AFTN. PWS INCREASE TO NEAR 2.0"...ALONG

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 443 AM EDT SATURDAY...FORECAST AREA WILL BE INBETWEEN A DEEP
TROUGH OVER THE MIDWEST AND A STRONG RIDGE OVER THE WESTERN ATLANTIC
FOR MUCH OF THE EXTENDED PERIOD. THE RESULT WILL BE A DEEP AND MOIST
SOUTHERLY FLOW OF AIR AND A CONTINUED THREAT FOR SHOWERS AND
THUNDERSTORMS. CHANCES FOR SHOWERS APPEAR HIGHEST EARLY IN THE
PERIOD WHEN REMNANTS OF SURFACE BOUNDARY WILL BE DRAPED ACROSS
REGION...PROVIDING A FOCUS FOR THE PRECIPITATION. OTHERWISE...
PRECIPITATION CHANCES AND THREAT OF THUNDERSTORMS EXPECTED TO
HIGHEST DURING AFTERNOON AND EVENING HOURS EACH DAY...DURING TIME
OF MAX HEATING AND INSTABILITY. SERIES OF HARD TO TIME SHORTWAVES
LIFTING NORTHEAST ACROSS THE REGION WILL ALSO ENHANCE CHANCES FOR
SHOWERS AT TIMES. WITH PRECIPITABLE WATER VALUES REMAINING VERY
HIGH THROUGH THURSDAY (NEAR 2 INCHES)...THERE WILL BE CONTINUED
THREAT FOR LOCALLY HEAVY DOWNPOURS AND POTENTIAL HYDRO CONCERNS...
GIVEN THE COPIOUS AMOUNTS OF RAIN WE HAVE RECEIVED THIS MONTH AND
THE SATURATED SOIL CONDITIONS. THERE ARE SOME INDICATIONS THAT BY
LATE IN THE WEEK THE RIDGE MAY RETROGRADE WEST FAR ENOUGH TO ALLOW
FOR FLOW TO BECOME MORE WESTERLY AND ZONAL...WHICH WOULD HELP DRY
THINGS OUT JUST A BIT. TEMPERATURES WILL BE ABOVE NORMAL THROUGH
THE PERIOD AND IT WILL BE HUMID. EXPECT VALLEY HIGHS IN THE MID
AND PERHAPS UPPER 80S...WITH LOWS MAINLY IN THE 60S.

MVFR/IFR POSSIBLE IN ANY SCATTERED SHOWERS OR THUNDERSTORMS. MAY
SEE MVFR/IFR IN SOME FOG/BR DURING THE OVERNIGHT HOURS IN ANY
PLACES THAT SEE RAIN.

&&

.HYDROLOGY...
AS OF 420 AM EDT SATURDAY...SCATTERED SHOWERS AND THUNDERSTORMS
ARE EXPECTED DAILY ACRS THE NORTH COUNTRY. THE THREAT FOR
ADDITIONAL FLOODING WITH POSSIBLE FLASH FLOODING WL INCREASE AGAIN
BY EARLY THIS UPCOMING WK...ESPECIALLY AS THE AVAILABLE MOISTURE
IN THE ATMOSPHERE INCREASES. THE COMBINATION OF DEEP MOISTURE
ADVECTION... SFC INSTABILITY...AND SFC BOUNDARY NEARBY WL HELP IN
THE DEVELOPMENT OF DAILY ROUNDS OF SHOWERS/STORMS. GIVEN THE
RECENT RAINS AND ALREADY SATURATED SOILS...VERY LITTLE ADDITIONAL
RAINFALL IS NEEDED TO CAUSE PROBLEMS. RAPID RISES ON LOCAL
WATERWAYS CAN BE EXPECTED IN AND AROUND ANY THUNDERSTORM ACTIVITY.
