DISCUSSION
DRY CONDITIONS AND LIGHT WINDS ARE EXPECTED TODAY. IT IS NOT
COMPLETELY OUT OF THE QUESTION THAT THERE IS AN ISOLATED SHOWER,
BUT THAT ACTIVITY IS MORE LIKELY TO STAY OFF TO THE SOUTH AND EAST.
MORE DRY CONDITIONS ARE LIKELY TUESDAY AND THE MIXING HEIGHT SHOULD
INCREASE TO ABOVE 7,000 FEET BY LATE MORNING. A SHOWER IS POSSIBLE
IN THE EVENING (MOST LIKELY AFTER 5 PM), BUT MOST PLACES SHOULD END
UP DRY.
