.SYNOPSIS
UPR LOW THAT BROT US CLOUDS AND RAINS TO US IS SPINNING OVR WRN-GA PER WV LOOP. FRONTAL BOUNDARY EXTENDS FROM KLEX TO KBNA TO KMSL. HERE IN W-TN OTHER THAN A FEW CLOUDS ROTATING THROUGH DECATUR AND HARDIN COUNTIES FROM THE UPR LOW, SKIES ARE CLEAR. TEMPS AT 09Z FROM REPORTING SITES ARE RANGING FROM 47 AT PHT TO 55 AT SNH. FOG HAS NOT BECOME A WIDESPREAD ISSUE AS OF 09Z UNLIKE IT WAS FROM 03Z-06Z. DEWPTS HAVE LOWER FROM MID 50S TO UPPER 40S DURING THAT TIME FRAME. 06Z SFC CHART HAD HIGH PRESSURE OVR NW AR. ANOTHER FRONT IS POSITONED FROM SRN WI INTO SRN KS.
.SHORT TERM [TODAY THROUGH SATURDAY]
LUKS LIKE MAIN CHALLENGE WILL BE TEMPS DURING THIS PERIOD AND SOME MID-LVL MOISURE WORKING INTO REGION ON SAT. UPR LOW IS TO SPIN INTO SRN GA AND OPEN UP TONIGHT THEN MOVE OFF THE COAST. MEANWHILE A TROF RAPIDLY DEVELOPS AND DIGS INTO THE WRN STATES THIS RESULTS IN PUMPING UP A RIDGE OVER THE EAST. A S/W WILL ROTATE THROUGH THE FLOW INTO AR AND MO BY SAT AM. IT IS EXPECTED TO DAMPEN OUT AS IT MOVES NE. MOISTURE FROM UPR TROF OFF SE COAST AND H70 HIGH OVR MID-ATL STATES WILL SHUNT SOME MOISTURE INTO THE TN VALLEY ROTATING AROUND THE HIGH INTO THE GRT. LAKES. WILL WATCH THE TRENDS ON THIS FOR NOW. WOULDN’T EXPECT TO SEE ANYTHING MORE THAT P/C SKIES FROM THIS ON SAT. BUT WILL STAY WITH A SUNNY/MOSUNNY FCST FOR NOW. MOS GUIDANCE LOOKS FINE AND WILL FOLLOW.
.LONG TERM [SATURDAY NIGHT THROUGH WEDNESDAY]
FLOW DE-AMPLIFIES DURING THIS PERIOD. RIDGE HOLDS STRONG THROUGH MONDAY AND THEN THE FLOW FLATTENS. IN THE PROCESS, TROF PUSHES A COLD FRONT INTO OUR AREA ON TUESDAY. GOMEX DOES NOT OPEN SIGNIFICANTLY TO MAKE THIS A BIG RAIN PRODUCER. MEX IS GOING WITH CHC POPS AND THAT MAY BE TOO GENEROUS. I WILL GO WILL SLGT CHC POPS ON TUES FOR NOW. HIGH PRESSURE WILL PREVAIL ON WED WITH DRY WEATHER. TEMPS SHOULD BE NEAR AVERAGE AFTER MONDAY.
