DISCUSSION
CANADIAN HIGH PRESSURE WILL SLOWLY PULL AWAY FROM THE ATLANTIC
COAST TODAY. AT THE SAME TIME, A STALLED FRONT IS EXPECTED TO
APPROACH FROM THE GREAT LAKES BEFORE CROSSING THE REGION AS A COLD
FRONT BY EARLY FRIDAY. THIS WILL COME WITH INCREASING STORM
CHANCES ALONG WITH A BRIEF PERIOD OF WARM TEMPERATURES AND
INCREASED HUMIDITY. 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 ALONG WITH A MARKED COOLING TREND STARTING MONDAY.
