AREA FORECAST DISCUSSION

.DISCUSSION...
A BROAD AREA OF LOW PRESSURE AT THE SURFACE CENTERED OVER NORTHERN
TEXAS COUPLED WITH A DEEP TROF ALOFT STRETCHING FROM CANADA ALL THE
WAY DOWN TO THE SOUTHERN GULF OF CALIFORNIA IS BRINGING RAIN TO THE
MID-MISSISSIPPI VALLEY THIS MORNING.  WATER VAPOR IMAGERY IS ALSO
SHOWING A GOOD SUB-TROPICAL JET STREAMING UP OUT OF THE EASTERN
PACIFIC WITH WHAT LOOKS LIKE DECENT DIFLUENCE ALOFT OVER US AS WELL.
THE SURFACE WARM FRONT WHICH IS NOW NEAR THE MO/AR BORDER WILL SLIDE
NORTH TODAY TO NEAR I-70 AS THE SURFACE LOW RIPPLES NORTHEAST ALONG
IT.  STRONG LOW LEVEL WARM ADVECTION ALONG AND AHEAD OF THE FRONT
WILL CONTINUE THROUGHOUT THE DAY...AND THIS WARM ADVECTION COUPLED
WITH THE UPPER DYNAMICS SHOULD KEEP US WET ALL DAY LONG.  TO USE A
GREAT PHRASE THAT ANOTHER FORECASTER HERE LIKES IF EVERY SQUARE
INCH OF THE FORECAST AREA DOESNT GET RAIN TODAY...WELL MISS A DARN
GOOD CHANCE.  FEEL THAT GOING FORECAST WITH MENTION OF HEAVY RAIN
IS EXCELLENT...AND WILL KEEP IT GOING...ALONG WITH THE FLOOD WATCH
THROUGH 00Z THIS EVENING.

THE UPPER TROF CONTINUES TO DEEPEN EVEN AS THE SURFACE LOW RIPS OFF
TO THE NORTHEAST OVERNIGHT TONIGHT AND INTO WEDNESDAY.  THE UPPER
TROF CUTS OFF AND ANOTHER SURFACE LOW FORMS OFF THE TEXAS/LOUISIANA
COAST AND MOVES NORTHEAST INTO THE OHIO VALLEY.  GOOD ISENTROPIC
LIFT IS INDICATED BY BOTH THE ETA AND GFS ACROSS THE AREA STARTING
OVERNIGHT TUESDAY NIGHT AND ON WEDNESDAY...BUT MORE SO WITH THE
ETA.  THE WARM CONVEYER BELT TRIES TO WRAP ALL THE WAY AROUND THE
SYSTEM...SO WOULD EXPECT SOME GOOD DEFORMATION ZONE-LIKE RAIN AND
DRIZZLE ON AFTER 06Z WEDNESDAY AND CONTINUING DURING THE DAYTIME
HOURS.  PROBLEM IS...THIS IS A MAJOR SHIFT IN THINKING FROM PREVIOUS
RUNS.  I INHERITED A FORECAST WITH 10 POPS IN IT FOR WEDNESDAY...AND
I AM RELUCTANT TO HIKE THE POPS UP TO MORE THAN 50 PERCENT GIVEN THE
UNCERTAINTY OF THE FORECAST.  HAVE GONE AHEAD WITH MID-HIGH CHANCE
POPS FOR THE ENTIRE CWFA ON WEDNESDAY.  WILL BRIEF THE DAY CREW ON
THIS CHANGE AND HOPEFULLY THEY WILL HAVE SOME BETTER MODEL
CONTINUITY TO WORK WITH.

HAVE KEPT TEMPERATURES FAIRLY COOL THROUGHOUT THE PACKAGE WHAT WITH
ALL THE PRECIP HANGING AROUND.  TODAY WILL BE TOUGH TO PIN DOWN
EXACTLY SINCE SO MUCH WILL DEPEND ON THE NORTHWARD PROGRESSION OF
THE WARM FRONT.  GENERALLY STUCK CLOSE TO TO A COMPROMISE BETWEEN
MOS NUMBERS FOR THE ENTIRE SHORT TERM.
