DISCUSSION
CANADIAN HIGH PRESSURE WILL SLOWLY EXIT TOWARD THE ATLANTIC COAST
THROUGH TONIGHT. AT THE SAME TIME, A COLD FRONT IS EXPECTED TO
APPROACH FROM THE GREAT LAKES BEFORE CROSSING THE REGION EARLY
FRIDAY. A GRADUAL WARM UP ENSUES DURING THE MIDDLE TO LATTER
PORTIONS OF THE WEEK, WITH STORM CHANCES RETURNING BY THURSDAY.
HIGH PRESSURE CROSSES THE NORTHEASTERN U.S. ON SATURDAY BEFORE A
FRONTAL SYSTEM REMAINS NEARBY ON SUNDAY INTO EARLY NEXT WEEK. THIS
BRINGS INCREASING SHOWER CHANCES ACROSS THE AREA.
SPOTTY RAINFALL AMOUNTS OF A QUARTER TO HALF INCH ARE POSSIBLE
THROUGH THE END OF THE WEEK, THOUGH MANY AREAS MAY REMAIN DRY.
WINDS WILL REMAIN GENERALLY LESS THAN 20 MPH EXCEPT PERHAPS AT THE
HIGHEST ELEVATIONS OCCASIONALLY THROUGH FRIDAY, OUT OF THE SOUTH
BEFORE SHIFTING TO THE NORTHWEST AT THE END OF THE WEEK.
AFTERNOON RH VALUES WILL DROP INTO THE 50S AND 60S WITH OVERNIGHT
RECOVERIES OF 80 TO 100 PERCENT.
