DISCUSSION...

TONIGHT THROUGH WEDNESDAY NIGHT...

EVIDENCE OF THE REINFORCING COLD FRONT IS SEEN IN VISIBLE
SATELLITE IMAGERY AND SFC OBS WITH STRATOCUMULUS DECK ROUGHLY ALONG
THE HIGHWAY 82 CORRIDOR ASSOCIATED WITH WEAK FRONTAL CONVERGENCE AND
LOWER TEMPS/DEWPOINTS MIXING IN BEHIND THE FRONT ACROSS NORTH MS.

EXPECT DRY CONDITIONS WITH SEASONABLY CHILLY NIGHTS AND MILD
AFTERNOON TEMPERATURES AS WE GO THROUGH MID WEEK. GIVEN SURFACE HIGH
PRESSURE RIDGING SOUTHWARD OVER THE ARKLAMISS AND CLEAR SKIES/LIGHT
WINDS ALONG WITH DRY SOIL CONDITIONS...TEMPERATURES COULD FALL
QUICKLY WEDNESDAY NIGHT. SOME OF THE GUIDANCE POINTS TO THE POTENTIAL
FOR TEMPERATURES TO GET DOWN TO NEAR 37F OVER EASTERN MS...BUT
PROBABLY NOT QUITE COLD ENOUGH TO WORRY ABOUT FROST. /EC/

THURSDAY THROUGH NEXT TUESDAY...A FAIRLY QUIET FORECAST IS SET TO
PREVAIL ACROSS THE FORECAST AREA THROUGH THE LONG TERM PORTION OF THE
FORECAST. TEMPERATURES WILL MODERATE UP A COUPLE OF DEGREES EACH DAY
FROM THE LOW TO MID 70S TO START THE PERIOD THURSDAY...TO AROUND 80
TO END THE FORECAST PERIOD NEXT TUESDAY. THE SAME GOES FOR
LOWS...WHICH WILL BEGIN THE PERIOD THURSDAY NIGHT IN THE LOW TO MID
40S AND WARM INTO THE MID 50S BY NEXT MONDAY NIGHT. A BOUNDARY
SWINGING THROUGH LATE FRIDAY COULD BRING SOME HIGH CLOUDS TO MAINLY
NORTHERN PORTIONS OF THE CWA. THEN TUESDAY AFTERNOON INTO TUESDAY
NIGHT...A WEAKENING COLD FRONT COULD BRING SOME LIGHT RAIN TO THE
REGION. /19/
