AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
353 PM CDT MON JUL 4 2005

.SHORT TERM......TONIGHT THROUGH THURSDAY
LOCAL RADARS INDICATE AN AREA OF CONVECTION AFFECTING EXTREME
NORTHEAST SECTIONS OF THE FORECAST AREA...IN A REGION OF THE
GREATEST BALANCE OF SHEAR AND INSTABILITY. SURFACE BOUNDARY FROM
NEAR MOUNTAIN HOME...TO MENA WILL CONTINUE TO MOVE
EAST-SOUTHEASTWARD OVERNIGHT. FORCING ASSOCIATED WITH THIS BOUNDARY
IS EXPECTED TO BE WEAK WITH THIS FEATURE.  STILL EXPECT ISOLATED TO
SCATTERED CONVECTION THROUGH LATE TUESDAY...BEFORE THE BOUNDARY
WASHES OUT.

&&

.LONG TERM......THURSDAY NIGHT THROUGH MONDAY
TROPICAL SYSTEM NO. 3 WILL BE MOVING INTO THE SOUTHEASTERN U.S.
EARLY FRIDAY. THE EFFECTS OF THIS SYSTEM BEING TO THE EAST OF THE
FORECAST AREA WILL BE NORTHEAST WINDS...WHICH TYPICALLY BRING COOLER
AND DRIER AIR TO THE STATE...ALONG WITH MAINLY CLEAR SKIES UNDER THE
SUBSIDENCE ZONE.

HIGH PRESSURE WILL WEDGE ITS WAY INTO THE REGION THROUGH THE
WEEKEND. THE PERSISTENT NORTHEAST FLOW AND UPPER LEVEL RIDGE OUT TO
MAKE FOR A GORGEOUS WEEKEND...ASSUMING YOU ENJOY PLENTY OF SUNSHINE
AND DRY WEATHER. BUT ITS NOT A GOOD THING FOR THE ONGOING DROUGHT.
NO PRECIP ANTICIPATED THROUGH THE WEEKEND. I DROPPED TEMPERATURES A
1-2 DEGREES ON HIGHS AND 2-3 DEGREES ON LOWS TO ACCOUNT FOR THE
COOLER WEATHER. DROPPED DEW POINTS 3-4 DEGREES AS WELL.

ALL LONG RANGE MODELS PICKING UP ON A NEW TROPICAL DISTURBANCE
...CURRENTLY AROUND 62W 11N. THE LATEST GFS BRING THIS SYSTEM OVER
FLORIDA LATE SUNDAY THROUGH MONDAY. AT THIS TIME...LOOKS LIKE THE
SYSTEM WILL STAY EAST OF ARKANSAS. THIS MEANS WELL BE IN THE AREA
OF WRAP AROUND DRY AIR. EXPECT NO PRECIP INTO EARLY NEXT WEEK IF
THIS PANS OUT...WITH CONTINUED TEMPERATURES SLIGHTLY BELOW NORMAL.

CONFIDENCE ON EXTENDED FORECAST FAIRLY GOOD...6/10. WHAT THE GFS IS
DELIVERING FOR THE SOLUTION TO THE WEATHER QUESTION LOOKS ABSOLUTELY
REASONABLE GIVEN THE EXPECTED SCENARIO.
