AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
300 PM CDT WED JUL 21 2004

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT
UPPER RIDGE HOLDING OVER THE AREA THIS AFTERNOON AND WILL GENERALLY
CONTINUE UNTIL FRIDAY WITH SOME MINOR CHANGES. COLD FRONT WILL
APPROACH FROM THE NORTH BUT WILL LIKELY HANG JUST NORTH OF THE
AREA INTO FRIDAY. SHOULD SEE LITTLE CHANGE TONIGHT THROUGH THURSDAY
NIGHT WITH NOT MANY CLOUDS AND PRACTICALLY NO CONVECTION AS CAPPING
SHOULD DOMINATE. TEMPS SHOULD BE CLOSE TO PERSISTENCE ALTHOUGH MAXES
MAY MOVE UP A LITTLE FROM EFFECTS OF THE APPROACHING FRONT. STILL
NOT A LOT OF CONFIDENCE IN TIMING OF FRONTAL PASSAGE ACROSS THE
AREA AS THE UPPER RIDGE REMAINS IN THE AREA. THERE STILL LOOKS TO BE
A SIGNIFICANT SHORT WAVE RIDING ALONG THE NORTHERN EDGE OF THE RIDGE
WHICH COULD HELP SEND THE FRONT INTO THE STATE LATE FRIDAY AND FRIDAY
NIGHT AND A SECOND SHORT WAVE SATURDAY MAY GIVE IT ANOTHER SHOVE.
WILL GO WITH THE FRONT BEING NEAR THE NORTHERN BORDER ON FRIDAY
AND SLOWLY MOVING TO THE SOUTH ACROSS THE STATE SATURDAY. MUCH OF
THE CONVECTION SHOULD BE ALONG OR BEHIND THE FRONT SO WILL NOT BEGIN
POPS IN THE NORTH UNTIL FRIDAY AND WILL INCREASE TO CHANCE POPS LATE
IN THE DAY. MEANWHILE...A SHORT WAVE FROM THE SOUTH SHEARS INTO
THE AREA FRIDAY AND WILL PUT SLIGHT CHANCE POPS IN THE SOUTH ON FRIDAY
DUE TO THIS. WILL KEEP POPS OUT OF CENTRAL SECTIONS FOR FRIDAY FOR
NOW. WILL INCREASE POPS TO CHANCE CATEGORY ACROSS THE AREA FRIDAY
NIGHT INTO SATURDAY AS THE FRONT MAY SHIFT TO THE SOUTH AND THE
REMNANTS OF THE SOUTHERN SHORT WAVE REMAIN IN THE AREA. GFS HINTING
AT AREA OF OVERRUNNING SATURDAY AND SATURDAY NIGHT. WILL GO LOWER ON
MAXES SATURDAY DUE TO EFFECTS OF THE FRONT AND THE ASSOCIATED CLOUDS
AND RAIN. MINS LIKELY WILL NOT CHANGE MUCH EXCEPT IN THE NORTH.
&&

.LONG TERM...SUNDAY THROUGH WEDNESDAY
DUE TO STRONG HIGH PRESSURE...THINK THAT THE FRONT WILL HAVE A HARD
TIME MAKING IT THROUGH THE STATE. AS SUCH...HAVE INTRODUCED POPS
FROM LITTLE ROCK SOUTH ON SUNDAY TO ACCOUNT FOR TIMING ISSUES. FOR
THE REST OF THE EXTENDED...WILL CONTINUE THE DRY FORECAST. NEW GFS
RUN STILL SHOWS CUT OFF LOW FORMING IN THE PLAINS/MISSISSIPPI
VALLEY...AND DO NOT THINK THAT IS FEASIBLE FOR THIS TIME OF YEAR.
