ANOTHER DAY OF WELL ABOVE NORMAL TEMPERATURES IS IN STORE AS SOME
WAA CONTINUES. REMNANTS OF "ISAIAS" WILL CONTINUE SLOWLY NORTH
THROUGH THE DAY AND EVENTUALLY MORE NORTHEAST TONIGHT INTO SUNDAY.
BANDS OF CIRRUS WILL WORK ACROSS THE AREA, GENERALLY THIN IN NATURE
UNTIL THE CIRCULATION EDGES CLOSER. SCATTERED SHOWERS MAY QUICKLY
MOVE NORTH ACROSS MUCH OF THE AREA NEAR/AFTER 3Z SUN THEN STEADIER
PRECIP ARRIVING AFTER 6Z AND LINGERING ALONG AND EAST OF INTERSTATE
69. QPF IS SOMEWHAT LOWER THAN PAST DAYS WITH AMOUNTS POSSIBLY AT
MOST LESS THAN ONE HALF INCH. MODEL BLENDS STILL KEEPING SOME SLGT
CHC POPS FOR THUNDER. LAPSE RATES NOT OVERLY IMPRESSIVE, BUT SOME
ELEVATED INSTABILITY IS NOTED (NEGATIVE SHOWALTERS). WILL LEAVE IN
FOR THE TIME BEING.
WITH REGARDS TO TEMPS ON SUNDAY, SOME GUIDANCE SUGGESTS HIGH TEMPS
COULD BE SEVERAL DEGREES COOLER (MAINLY EAST) WHICH COULD HAVE SOME
VALIDITY WITH THE EXTENSIVE CLOUD COVER AND PRECIP. THESE TEMPS SEEM
TO BE IN THE LOWER PERCENTILE RANGE, SO HAVE LEFT PREVIOUS HIGHS
ALONE AND PASS ONTO THE NEXT SHIFT.
LULL IN PRECIP CHANCES ARRIVES SUNDAY NIGHT INTO MONDAY, BEFORE A
SERIES OF WEAK WAVES AND FRONTS ARRIVE FOR MID WEEK. THEREAFTER, MED
RANGE MODELS HAVE SORT OF DIVERGED SOME ON THE DEGREE OF PHASING OF
A WEAKER NORTHERN AND STRONGER SOUTHERN STREAM WAVE. POPS REMAIN IN
PLACE WITH SIGNS STILL POINTING TOWARDS COOLING FOR THE WEEKEND, BUT
THE DEGREE OF COOLING AND AMOUNT OF PRECIP IS IN QUESTION WITH THESE
VARIATIONS.
