AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 405 AM CST TUE DEC 7 2004 .SHORT TERM... FOR TODAY THROUGH THURSDAY NIGHT... BEEN A BUSY NIGHT. CURRENT WATER VAPOR IMAGERY SHOWS A POTENT NEGATIVE TILTED SHORT WAVE LIFTING OUT OF THE SOUTHERN PLAINS TRIGGERING THE STRONG CONVECTION ACROSS THE LOWER MISSISSIPPI VALLEY. THE DISTURBANCE IS ACTUALLY A LITTLE STRONGER THAN EARLIER MODELS HAD PREDICTED AT THIS POINT. EXPECT THE SURFACE REFLECTION (SURFACE LOW) TO MOVE RAPIDLY NORTHEAST THROUGH THE GREAT LAKES REGION AS THE LAST OF THE STRONG CONVECTION EXITS THE REGION BY MID MORNING. THE RAIN WILL EXIT THE EAST AND SOUTH BY MIDDAY. PARTLY CLOUDY SKIES AND CONTINUED WARM CONDITIONS WILL BE BUILDING BACK IN. HOWEVER...IT NOW LOOKS LIKE THE PLEASANT WEATHER WILL NOT LAST TOO LONG AS ANOTHER DISTURBANCE WILL TAKE SHAPE AND APPROACH WEDNESDAY. THIS FEATURE WILL BEGIN TO RETURN THE FRONTAL BOUNDARY NORTH WITH ISENTROPICLY LIFTED MOISTURE PROMPTING INCREASING CLOUDS...AND EVENTUALLY PRECIP...BY WEDNESDAY NIGHT GOING INTO THURSDAY. LOOKS LIKE SOME DECENT RAINFALL AMOUNTS WITH THIS SYSTEM WITH A THATAE RIDGE OF ABOUT 330...PCP WATER AROUND 1.8 INCHES...WITH RAINFALL AMOUNTS OF 1 TO 3 INCHES ALONG WITH SOME UPPER DIVERGENCE OF A 115 KNOT JET.

THE GFS/ETA EXTENDED/UKMET ON FRIDAY A LARGE UPPER TROUGH WITH A 530 CLOSED LOW WILL BE OVER THE EASTERN HALF OF THE NATION.

ON MONDAY ANOTHER SHORT WAVE RESHAPES THE UPPER TROUGH OVER THE EASTERN HALF OF THE NATION. THIS WILL KEEP THE REGION UNDER DRY NORTHWEST FLOW. SO WILL KEEP DRY WEATHER FOR THE LONG TERM AND MAKE MINOR CHANGES TO TEMPS. && PRELIMINARY TEMP/POPS JACKSON 71 46 71 56 / 20 10 10 50 MERIDIAN 73 46 72 56 / 60 10 10 50 && .JAN WATCHES/WARNINGS/ADVISORIES... .MS...NONE .LA...NONE. .AR...NONE. && 17
