.DISCUSSION...

UNDER THE INFLUENCE OF HIGH PRESSURE RIDGE ALOFT AND SURFACE HIGH
PRESSURE...COOL TEMPERATURES CONTINUED TO PREVAIL OVER THE FOUR
STATE REGION THIS MORNING. THE COOL TEMPERATURES AND LIGHT WINDS
ALONG WITH A WET GROUND FROM RECENT RAINS WILL PROVIDE THE AREA WITH
PATCHY FOG THAT WILL GRADUALLY ERODE INTO THE EARLY TO MID MORNING
HOURS. SOME AREAS WILL SEE MORE DENSE PATCHES THAN OTHERS AND
EARLY MORNING TRAVELERS DURING THE MORNING COMMUTE MORNING MAY
WANT TO USE CAUTION DUE THE VISIBILITY RESTRICTIONS. THIS MORNING
THE UPPER RIDGE WAS CENTERED OVER THE EASTERN SECTIONS OF NEW
MEXICO AND THE WESTERN PAN HANDLE REGION OF TEXAS WHILE TO THE EAST
AN UPPER LEVEL LOW WAS CENTERED OVER NORTHERN ALABAMA. DRIER AIR
MOVING SOUTH BETWEEN THE TWO SYSTEMS WILL PROVIDE DRY WEATHER INTO
LATE TUESDAY. THE UPPER LOW WILL RETROGRADE INTO SOUTHERN MISSISSIPPI
BY LATE TUESDAY WHILE THE RIDGE OF HIGH PRESSURE CENTER SHIFTS
INTO CO. MOISTURE MOVING IN FROM THE GULF OF MEXICO WITH
DISTURBANCES MOVING AROUND THE UPPER LOW WILL PROVIDE THE SOUTHERN
ZONES WITH A SLIGHT CHANCE OF RAIN. BY WEDNESDAY THE UPPER LOW
CONTINUES IT DRIFT ACROSS SOUTHERN LOUISIANA KEEPING RAIN CHANCES
FOR THE SOUTH WHILE AN UPPER LEVEL TROUGH DROPPING SOUTHWEST FROM
THE GREAT LAKES...MOVES AROUND THE NORTHEAST SIDE OF THE UPPER
LEVEL RIDGE OVER THE ROCKIES PROVIDING SHOWERS AND THUNDERSTORMS
OVER THE NORTHERN ZONES. FOR THURSDAY AS THE UPPER LOW MOVES DOWN
THE TEXAS COAST AND INTO THE NORTHWEST GULF OF MEXICO...THE TROUGH
SHIFTING EAST ACROSS THE TENNESSEE VALLEY AND LOWER MISSISSIPPI
VALLEY SHIFTS A COLD FRONT INTO NORTHEAST TEXAS AND ALONG THE
THE LOUISIANA AND ARKANSAS BORDER REGION. CLOUD COVER AND RAIN
WILL PROVIDE COOLER TEMPERATURES FOR MUCH OF THE FORECAST AREA.
THE FRONT WILL BECOME NEARLY STATIONARY ACROSS NORTHEAST TEXAS
AND INTO NORTHEAST LOUISIANA AND START TO LIFT BACK NORTHEAST
ON FRIDAY WITH RAIN CHANCES SHIFTING NORTH WITH THE BOUNDARY FOR
FRIDAY NIGHT. FOR THE WEEKEND THE UPPER LEVEL RIDGE OF HIGH
PRESSURE EXPANDS EAST ACROSS THE FOUR STATE REGION KEEPING THE
AREA MOSTLY DRY WITH TEMPERATURES WARMING WELL BACK INTO THE
NINETIES FOR DAYTIME HIGHS. ANOTHER TROUGH OF LOW PRESSURE
AMPLIFIES SOUTH AS IT MOVES AROUND THE EASTERN PERIPHERY OF THE
UPPER RIDGE FOR THE LATER PART OF THE WEEKEND PROVIDING THE EASTERN
