SURFACE TROUGHING TAKING SHAPE OVER THE EASTERN UNITED STATES IS
NUDGING THE WESTERN FLANK OF AN ATLANTIC RIDGE EAST AND
SOUTHEASTWARD TONIGHT. AS A RESULT, THE RIDGE AXIS WILL DRAW
CLOSER TO THE KEYS REGION RESULTING IN EAST TO SOUTHEASTERLY
BREEZES TRENDING DOWNWARDS. WITH THAT SAID, THE USUAL LATE EVENING
PICKUP IS EXPECTED OVER THE NEXT FEW HOURS, BUT IT WILL BE MODEST.
EXPECT WARM AND HUMID CONDITIONS WITH LOWS IN THE LOWER TO MID 80S
AND DEW POINTS REMAINING IN THE MID 70S.
DESPITE THE PREVIOUSLY MENTIONED TROUGHING, DEEP LAYERED RIDGING
WILL REMAIN AT PLAY ACROSS OUR AREA. THE SURFACE THROUGH LOWER
LEVEL RIDGE WILL REMAIN OVERHEAD, WHILE THE FLOW BECOMES NEBULOUS
AT 500 MB. THE RIDGING IS HELPING TO KEEP MOISTURE LIMITED. THIS
EVENINGS SOUNDING INDICATED PRECIPITABLE WATER UP SLIGHTLY, BUT
STILL BELOW NORMAL AT 1.27 INCHES. THERE WAS ALSO SOME LOWER LEVEL
INHIBITION. WHILE THE INHIBITION IS EXPECTED TO WEAKEN SOME
OVERNIGHT, SOME INHIBITION WILL LINGER. THIS, ALONG WITH A LACK OF
FORCING AND CONTINUED LACK OF DEEP LAYERED MOISTURE WILL KEEP RAIN
CHANCES SLIGHT AT BEST.
