GFS/ECMWF AND NAM SHOW MID/UPPER LVL TROF AXIS BECMG SHARPER...WITH MORE OF A 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 WITH A BOUNDARY NEARBY. THIS SFC BOUNDARY WL SERVE AS A FOCUS FOR ADDITIONAL ROUNDS OF SHOWERS/STORMS...ESPECIALLY ON MONDAY. IN ADDITION...A RRQ OF 25H JET OF 100 TO 120 KNOTS WL BE ACRS SOUTHERN CANADA...PLACING OUR REGION IN FAVORABLE ULVL DIVERGENCE...FOR ENHANCED DEEP LAYER LIFT. STILL SOME UNCERTAINTY WITH REGARDS TO SFC HEATING/INSTABILITY EACH AFTN...PER CLOUD COVER AND BL DWPTS.

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.

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.
