A LARGE UPPER TROF DEVELOPS OVER THE WESTERN CONUS THROUGH
TONIGHT, THEN TAKES ON A POSITIVE TILT THROUGH TUESDAY TO EXTEND
FROM THE NORTHERN PLAINS TO THE SOUTHWESTERN STATES. THE PATTERN
EVOLVES TO A MERIDIONALLY ORIENTED UPPER TROF OVER THE PLAINS BY
THURSDAY, THEN MUCH OF THE UPPER TROF (ALONG WITH A QUICKLY
FOLLOWING SYSTEM) EJECTS OFF ACROSS THE NORTHEAST STATES OVER THE
WEEKEND. A NARROW UPPER RIDGE MEANWHILE BUILDS ACROSS THE EXTREME
SOUTHEAST STATES THROUGH TUESDAY THEN GRADUALLY WEAKENS WEDNESDAY
INTO THURSDAY AND DISSIPATES BY FRIDAY AS THE UPPER TROF BEGINS
TO PROGRESS ACROSS THE NORTHEAST STATES ALONG WITH A SERIES OF
SHORTWAVES WORKING INTO THE AREA. A SOUTHERLY DEEP LAYER FLOW
OVER THE FORECAST AREA WILL LEAD TO IMPROVING MOISTURE BELOW 800
MB ON MONDAY WHILE DRY MID LEVEL AIR PERSISTS. ANTICIPATE THAT
ISOLATED TO POSSIBLY SCATTERED CONVECTION WILL DEVELOP ON MONDAY
IN RESPONSE TO A FEW MODEST SHORTWAVES MOVING ACROSS THE AREA AND
AIDED BY THE SEA BREEZE. THE DRY MID LEVEL AIR WILL AID IN
DOWNDRAFT PRODUCTION, THOUGH SEVERE STORM DEVELOPMENT IS NOT
ANTICIPATED AT THIS TIME.
SUBSIDENCE EFFECTS ASSOCIATED WITH THE UPPER RIDGE LOOK TO
INHIBIT CONVECTIVE DEVELOPMENT ON TUESDAY, ALTHOUGH A FEW
SHOWERS/STORMS WILL BE POSSIBLE. AS THE UPPER RIDGE SLOWLY WEAKENS
WEDNESDAY AND THURSDAY (EVENTUALLY DISSIPATING BY FRIDAY), A
SERIES OF SHORTWAVES BECOME MORE ACTIVE OVER THE AREA. WILL HAVE
SLIGHT CHANCE/CHANCE POPS OVER MUCH OF THE AREA ON WEDNESDAY
GRADUALLY TRENDING TO CHANCE TO LIKELY POPS BY SATURDAY. A LOW
RISK OF RIP CURRENTS TONIGHT WILL BE FOLLOWED BY A MODERATE RISK
FROM MONDAY THROUGH THURSDAY. PATCHY FOG WILL BE POSSIBLE TONIGHT
AND MONDAY NIGHT, MAINLY OVER INTERIOR AREAS. GUIDANCE INDICATES
THAT DENSE FOG MAY BE POSSIBLE EAST OF I-65 MONDAY NIGHT WHICH
WILL BE MONITORED. /29
