PREPARING FOR MORE RAIN.  PEEKING AT WATER VAPOR LOOP...TRACKING AN
EXTREMELY LONG PLUME OF TROPICAL MOISTURE...STRECTHING WEST TO THE
PACIFIC ITCZ SOUTHEAST OF HAWAII.  THIS MOISTURE IS SURGING FROM THE
SOUTHWEST AROUND THE BASE OF A LARGE POSITIVELY TILTED TROF FROM
NORTHERN MINNESOTA TO BAJA CALIFORNIA.  THIS JUICY AIR IS RIDING
OVER A RESIDUAL...SOMEWHAT HARD TO IDENTIFY...SURFACE FRONT JUST
SOUTH OF THE AREA.  KSJT AND KDYS 88DS ARE LIT UP LIKE CHRISTMAS
TREES WITH ALL OF THE PRECIP GOING ON.  WITH AN UPPER RIDGE LOCKED IN
OVER THE NORTHERN GULF OF MEXICO...THE PREVIOUSLY MENTIONED TROF
SHOULD NOT SLIDE EAST...AND MODELS GIVE ALL INDICATION OF A
SOUTHWEST DRIFT AS IT INTENSIFIES...HELPED ALONG BY A 100 KNOT SPEED
MAX ROTATING AROUND ITS BASE.  WITH NO MOVEMENT IN THE ORIENTATION
OF THE TROPICAL PLUME...NO SUPPORT TO PUSH THE SURFACE FRONT OUT OF
THE AREA...AND AN EXPECTED WARM AND JUICY AIRMASS IN PLACE...SEE
MORE RAIN IN THE NOT TOO DISTANT FUTURE.  TIMING OF SHORT WAVE
ENERGY IS THE ONLY LIMITING FACTOR IN PINPOINTING PRECIP...BUT A
SNEEZE IS ALL THE LIFT NEEDED TO TAP INTO THIS MOIST AIRMASS.
BASICALLY...WILL EXTEND AND EXPAND THE FLASH FLOOD WATCH GOING...
NOW INCLUDING ALL OF THE FORECAST AREA.  WITH ALL OF THE CLOUD COVER
AND THE PRECIP...DIURNAL TEMPERATURE RANGE WILL REMAIN SMALL.
