GOES WATER VAPOR SATELLITE TRENDS SHOWED A MID-LEVEL SHORTWAVE
TROUGH MOVING THROUGH PORTIONS OF WESTERN KENTUCKY AND NORTHWEST
TENNESSEE LATE THIS MORNING. AS A RESULT, REGIONAL WSR-88D RADAR
TRENDS INDICATED ELEVATED SCATTERED SHOWERS AND THUNDERSTORMS
OCCURRING OVER PORTIONS OF WEST TENNESSEE NEAR THE TENNESSEE
RIVER. LATE MORNING TEMPERATURES RANGED FROM THE UPPER 60S TO
LOWER 70S NORTH OF I-40, AND MIDDLE 70S TO MIDDLE 80S SOUTH.
ABUNDANT CLOUD COVER AND NORTHEAST WINDS ALONG AND NORTH OF THIS
LINE WILL RESULT IN LOWER AFTERNOON TEMPERATURES THAN DEPICTED BY
THE NBM GUIDANCE. THUS, TEMPERATURES WERE SUBSEQUENTLY LOWERED TO
ACCOUNT FOR THESE TRENDS. SHORT TERM CAMS SUGGEST THIS ACTIVITY
WILL GRADUALLY WEAKEN AND DISSIPATE INTO THIS AFTERNOON AS THE
SHORTWAVE TROUGH PUSHES AWAY FROM THE REGION. COOLER AND DRIER
AIR WILL FILTER INTO THE AREA AS HIGH PRESSURE SETTLES IN FROM
ONTARIO AND QUEBEC. THIS WILL RESULT IN MORE COMFORTABLE NEAR
NORMAL TEMPERATURES ACROSS THE MID-SOUTH WITH HIGHS IN THE LOWER
TO MIDDLE 80S NORTH OF I-40, AND MIDDLE 80S TO AROUND 90 DEGREES
SOUTH, WITH LOWS IN THE UPPER 50S TO 60S.
LONG TERM ENSEMBLE MODEL SOLUTIONS SHOW THE MID-SOUTH REMAINING
WITHIN NORTHWEST FLOW ALOFT THROUGH THE END OF THE PERIOD WITH AN
UPPER-LEVEL TROUGH LOCATED ALONG THE EASTERN U.S. AND A RIDGE
OVER THE SOUTHERN PLAINS INTO WESTERN PORTIONS OF THE LOWER
MISSISSIPPI VALLEY. CONFIDENCE REMAINS MEDIUM TO HIGH FOR
TEMPERATURES RISING BACK ABOVE NORMAL FOR THE UPCOMING WEEKEND
INTO EARLY NEXT WEEK BUT WITHOUT THE ANOMALOUSLY HIGH
TEMPERATURES WE HAVE EXPERIENCED LATELY. BEYOND EARLY NEXT WEEK,
ENSEMBLE SOLUTIONS DAMPEN OUT THE RIDGE WITH TEMPERATURES
BECOMING MORE SEASONABLE NEAR NORMAL HIGHS FOR LATE SEPTEMBER.
