CONCERNING...SEVERE THUNDERSTORM WATCH 527...
VALID 172034Z - 172200Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 527
CONTINUES.
SQUALL LINE ARCING FROM SERN MO ACROSS THE LOWER OH VALLEY CONTINUES
DEVELOPING SWD LATE THIS AFTERNOON. WIND GUSTS ACCOMPANYING THE
TSTMS AND WIND SHIFT HAVE GENERALLY BEEN IN THE RANGE OF 20-25KT
WITH A RECENT DOWNWARD TREND IN LIGHTNING AND REFLECTIVITY ALONG THE
ERN EXTENT OF THE BOWING LINE...GENERALLY EAST OF THE MS RIVER. VERY
WARM AND UNSTABLE AIR MASS ACROSS THE MO BOOTHEEL AREA...AND OUTFLOW
BOUNDARY INTERSECTION MOVING INTO THIS AREA...WILL LIKELY SUSTAIN
SEVERE STORM POTENTIAL ACROSS THIS PORTION OF THE WATCH. WHILE AIR
MASS IS LESS UNSTABLE FARTHER EAST...MESOSCALE FORCING FOR ASCENT
ALONG THE OUTFLOW COULD STILL RESULT IN A FEW MORE ROBUST STORMS
ACROSS THE SRN PORTIONS OF WATCH 527 INTO EARLY EVENING.
