DISCUSSION
HIGH PRESSURE WILL REMAIN ANCHORED OFFSHORE THROUGH WEDNESDAY
WHILE A FRONTAL SYSTEM STALLED OVER THE GREAT LAKES AND INTERIOR
NORTHEAST STARTS A SLOW SOUTHEASTWARD DRIFT. THIS WILL RESULT IN
NEAR RECORD TEMPERATURES. EVEN THOUGH DEW POINTS WILL ALSO BE
RISING, THE LARGE SPREAD WITH THE TEMPERATURES WILL RESULT IN
AFTERNOON RH IN THE 40S. SOUTHWESTERLY WINDS WILL ALSO
REMAIN GUSTY. REGIONAL OBSERVATIONS SHOW GUSTS AROUND 20 TO 30
MPH. HOWEVER, FORESTED AREAS OR SLOPES SHELTERED TO THE SOUTHWESTERLY
FLOW MAY ONLY SEE GUSTS TO AROUND 15 MPH AS SEEN AT THE NEARBY RAWS.
WHILE CUMULUS CLOUDS ARE BUBBLING UP, SHOWERS HAVE YET TO FORM,
AND WHILE A POP-UP CAN'T TOTALLY BE RULED OUT THROUGH THE END OF
THE AFTERNOON, IT IS UNLIKELY ONE AFFECTS THE BURN SITE.
THE FRONT WILL DROP SOUTHWARD WEDNESDAY, THEN STALL NEARBY OR
OVERHEAD THURSDAY, INCREASING THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS. WINDS SHOULD BE A LITTLE LIGHTER ON WEDNESDAY, ALTHOUGH
THE RELATIVE HUMIDITY MAY ALSO BE A LITTLE HIGHER.
