DISCUSSION
DRY AND WINDY TODAY. EXPECT AFTERNOON RH IN THE MID-20S. AROUND A
25% CHANCE OF SEEING RH FALL BELOW 20% IN THE AFTERNOON, BUT IF THIS
HAPPENS IT WILL ONLY BE BRIEF.
DAY SHIFT BRIEFED ME THAT 25MPH IS A CRITICAL THRESHOLD FOR YOUR
OPERATIONS, SO...CURRENTLY EXPECT A WINDOW IN THE MORNING, BETWEEN
0900 AND 1200, DURING WHICH GUSTS COULD INDEED GET TO 25-27MPH, THOUGH
ONLY SPORADICALLY, AS A COLD FRONT CROSSES OVERHEAD. CRITICALLY,
**THIS WINDOW WILL BE AT THE SAME TIME AS THE WIND DIRECTION SHIFTING
FROM THE W TO THE NNW**...SO ONCE YOU SEE THE PREVAILING WIND STAY
RELIABLY OUT OF THE NNW, THE PERIOD OF MAX GUSTS IS LIKELY OVER, AND
THE 25MPH THRESHOLD IS UNLIKELY TO BE MET THEREAFTER.
IN CASE THIS 25MPH THRESHOLD REQUIRES OVERLAP WITH LOW RH, IT CURRENTLY
LOOKS VERY UNLIKELY THAT RH WILL FALL BELOW 40% DURING THE PERIOD WHEN
GUSTS MAY REACH 25MPH.
IF YOU'D LIKE CLARIFICATION ON THIS, OR WANT A REAL-TIME UPDATE AS THE
DAY PROGRESSES, CALL THE OFFICE AND THE METS THERE CAN HELP.
DURING THE AFTERNOON, GUSTS ARE ONLY EXPECTED IN THE 15-20MPH RANGE,
WHILE WINDS WILL STAY OUT OF THE N/NW. IT IS DURING THE MID TO LATE
AFTERNOON, LIKELY AFTER 3PM, WHEN RH IS MOST LIKELY TO CRATER TO VALUES
BELOW 30%.
WON'T DWELL TOO MUCH ON TUESDAY. EXPECT EVEN DRIER RH, BUT LIGHER WINDS,
WITH SPORADIC GUSTS EXPECTED TO REMAIN BELOW 20MPH.
