DISCUSSION
KEY MESSAGE #1: STRATUS AND FOG SPREADING ACROSS THE REGION
THROUGH THE EARLY MORNING.
SATELLITE IMAGERY AND OBSERVATIONS INDICATE THAT A GENERAL RINSE
AND REPEAT OF THE PAST COUPLE OF NIGHTS IS OCCURRING. AT THIS
TIME, A STRATUS DECK CONTINUES TO SPREAD WESTWARD ACROSS THE
FORECAST AREA, WITH SOME EMBEDDED FOG IN THE EASTERN PORTIONS.
SOME PATCHY DENSE FOG IS BEING REPORTED JUST EAST OF THE AREA.
EXPECT THE STRATUS AND FOG TO CONTINUE SPREADING WESTWARD INTO
THE EARLY MORNING HOURS. SOME LOCALIZED DENSE FOG REMAINS
POSSIBLE FOR THE EASTERN PORTIONS OF THE FORECAST AREA AS WE
PROGRESS THROUGH THE NIGHT. AT THIS TIME, IT DOES NOT LOOK LIKE
IT WILL BE WIDESPREAD, SO NOT ANTICIPATING A DENSE FOG ADVISORY.
KEY MESSAGE #2: TEMPERATURES CONTINUE TO BE WELL ABOVE NORMAL
THROUGH AT LEAST THE MID WEEK NEXT WEEK.
THE STRONG MID TO UPPER RIDGE SITTING OVER THE REGION IS
FORECAST TO REMAIN OVER THE SOUTHEAST FOR THE NEXT SEVERAL DAYS.
HOWEVER, GUIDANCE SUGGESTS THAT THE TROUGH CURRENTLY OVER THE
GREAT PLAINS MOVES EASTWARD TODAY INTO SUNDAY, TEMPORARILY
FLATTENING THE RIDGE OUT SOMEWHAT. MEANWHILE, THE SOUTHERN
PORTION OF THE AFOREMENTIONED TROUGH IS FORECAST TO BECOME A
CLOSED LOW AND DRIFT OVER BAJA CALIFORNIA. EVENTUALLY, THIS
FEATURE IS EXPECTED TO EJECT EASTWARD, ALLOWING THE RIDGE OVER
THE SOUTHEAST TO RESTRENGTHEN. DESPITE THE FLATTENING OF THE
RIDGE THE NEXT COUPLE OF DAYS, GEOPOTENTIAL HEIGHTS ARE STILL
FORECAST TO BE ANOMALOUSLY HIGH OVER THE REGION. THEREFORE, THE
TEMPERATURES ARE FORECAST TO REMAIN WELL ABOVE NORMAL. WITH THE
RIDGE RESTRENGTHENING LATER IN THE FORECAST PERIOD, TEMPERATURES
BUMP UP EVEN HIGHER FORE MIDWEEK AHEAD OF THE NEXT POTENTIAL
TROUGH. ENSEMBLE SPREADS THROUGH MIDWEEK REMAIN RATHER SMALL,
LEADING TO A HIGHER CONFIDENCE IN THESE HIGH TEMPS. THE SPREAD
INCREASES QUITE A BIT LATE IN THE WEEK, LEADING TO MORE
UNCERTAINTY.
KEY MESSAGE #3: CHANCE OF DIURNAL SHOWERS INTO NEXT WEEK.
ALTHOUGH THE RIDGE IS FORECAST TO BEGIN FLATTENING SOME TODAY,
THE WESTERN PERIPHERY IS EXPECTED TO STAY JUST TO OUR WEST.
THEREFORE, THE BEST CHANCES FOR ANY SHOWERS (AND POSSIBLY A
THUNDERSTORM) THIS AFTERNOON ARE IN THE WESTERN PORTIONS OF THE
FORECAST AREA. THE TROUGH MENTIONED IN KEY MESSAGE #2 IS
EXPECTED TO PUSH A FRONT TOWARD THE AREA FOR SUNDAY, BUT IT IS
FORECAST TO BECOME WASHED OUT TO SOME EXTENT. THAT SAID, THERE
SHOULD BE ENOUGH FORCING IN THE AREA TO PRODUCE MORE COVERAGE OF
SHOWERS AND STORMS THAN SATURDAY. THE THREAT FOR SEVERE WEATHER
REMAINS LOW AS THE BEST DYNAMICS ARE EXPECTED TO BE NORTH OF THE
AREA. HOWEVER, A STRONGER STORM CANNOT BE RULED OUT, ESPECIALLY
NEAR THE CHARLOTTE METRO INTO THE PEEDEE REGION. WITH THE
RESIDUAL HEAT AND MOISTURE, CHANCES FOR DIURNAL SHOWERS
CONTINUES INTO THE EARLY PART OF THE WEEK. DUE TO THE LACK OF A
FORCING MECHANISM, COVERAGE IS ANTICIPATED TO BE ISOLATED,
HOWEVER. A FRONTAL BOUNDARY LATE IN THE WEEK COULD BRING HIGHER
CHANCES FOR RAINFALL TO THE AREA.
AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
RESTRICTIONS EXPECTED TO CONTINUE EARLY THIS MORNING, BUT RETURN TO
VFR AFTER SUNRISE.
GIVEN THE OVERALL PATTERN HAS NOT CHANGED MUCH FROM THE LAST
COUPLE OF NIGHTS, IT'D BE FOOLISH TO THINK THE SENSIBLE WEATHER
WOULD VARY CONSIDERABLY. A PROMINENT STRATUS DECK CONTINUES TO
DEVELOP AND ADVECT INLAND GIVEN ABUNDANT LOW LEVEL MOISTURE. SOME
PATCHY FOG AND VSBY RESTRICTIONS ARE ALSO POSSIBLE, BUT OVERALL IFR
TO LIFR CIGS WILL DOMINATE THROUGH AN HOUR OR TWO AFTER SUNRISE.
CIGS ARE EXPECTED TO SCATTER OUT AND LIFT BY MID TO LATE MORNING,
GIVING WAY TO VFR CONDITIONS BY AFTERNOON UNDER PARTLY CLOUDY SKIES.
SCATTERED CONVECTION IS POSSIBLE ONCE AGAIN IN THIS WARM AND HUMID
AIRMASS, BUT CHANCES ARE NOT HIGH ENOUGH TO INCLUDE IN THE TAFS AT
THIS TIME. SFC WINDS GENERALLY SOUTHERLY, LESS THAN 12 KTS.
EXTENDED AVIATION OUTLOOK...PATCHY MORNING FOG REMAINS POSSIBLE EACH
DAY. INCREASED SHOWER AND STORM CHANCES EXPECTED STARTING SUNDAY,
LASTING INTO NEXT WEEK.
