AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1116 AM CDT FRI JUL 20 2007

.DISCUSSION...
WIDESPREAD MID LEVEL CLOUDS ARE STILL EVIDENT ON VISIBLE SATELLITE
IMAGERY LATE THIS MORNING OVER MUCH OF EASTERN LOUISIANA AND SOUTHERN
MISSISSIPPI. FURTHER SOUTH TOWARDS THE NATCHEZ AREA...THIS CLOUD DECK
IS BECOMING MORE CONVECTIVE IN NATURE AND WITH LOWER CLOUD BASES. AS
A RESULT...TEMPERATURES SHOULD BE A BIT SLOWER TO HEAT UP...AND THIS
HAS BEEN ACCOUNTED FOR IN THE LATEST FORECAST UPDATE. FURTHER TO THE
NORTH...ESPECIALLY NORTH AND EAST OF JACKSON...MOSTLY SUNNY SKIES
WILL ALLOW FOR A MORE RAPID INCREASE IN TEMPERATURES...AND THIS IS
WHERE THE WARMEST HIGHS SHOULD BE FOR TODAY. A SIGNIFICANT COLD FRONT
FOR THIS TIME OF YEAR IS APPROACHING NORTHERN MISSISSIPPI AND THIS
SHOULD PROVIDE AMPLE FORCING FOR SCATTERED TO PERHAPS WIDESPREAD
CONVECTION FOR WFO JAN NORTHERN ZONES...PARTICULARLY NORTH OF HIGHWAY
82. HOURLY TEMP GRIDS WERE ADJUSTED DOWNWARD SLIGHTLY TO ACCOUNT FOR
THE INCREASED CLOUD COVER AND RAIN EXPECTED. POPS WERE ALSO RAISED IN
THE NORTHERN ZONES IN RESPONSE TO THE APPROACHING FRONT AND
EXPECTED CONVECTION ASSOCIATED WITH IT. LITTLE IN THE WAY OF CHANGES
WERE WARRANTED ELSEWHERE.

&&

.AVIATION...
VFR CONDITIONS SHOULD PREVAIL AT ALL LOCATIONS THROUGH AT LEAST 20Z
TODAY. AFTERNOON CONVECTION WILL BE POSSIBLE AFTER 20Z...WITH THE
GREATEST COVERAGE EXPECTED FOR GTR...GWO...AND GLH. CONDITIONS MAY
BRIEFLY BECOME IFR IN AND AROUND THUNDERSTORMS...BUT THE MAJORITY OF
THE DAY SHOULD BE VFR. VISIBILITIES SHOULD REMAIN AT OR ABOVE 10
MILES OUTSIDE OF THUNDERSTORMS.
