VARIABLE CLOUD COVER ALONG WITH MAINLY DRY WEATHER AND ABOVE NORMAL TEMPERATURES WILL BE THE RULE INTO MONDAY AS HIGH PRESSURE REMAINS THE DOMINANT FEATURE OVER THE NORTHEAST.

WITH THE WEAK WINDS UNDER THE SURFACE RIDGE EXPECT GOOD RADIATIONAL COOLING TO PERSIST OVERNIGHT DROPPING TEMPS INTO THE UPPER 30S TO LOW 40S SIMILAR TO THE PREVIOUS LINE OF THINKING. NO SIGNIFICANT CHANCES TO THE FORECAST. PREVIOUS DISCUSSION AS OF 1037 PM FRIDAY...TRANQUIL CONDITIONS EXPECTED THROUGH THE REMAINDER OF THE OVERNIGHT PERIOD. THE ISOLD LIGHT RAIN SHOWER ACTIVITY ACROSS THE ST. LAWRENCE VALLEY AROUND 23Z GRADUALLY DISSIPATED AS IT MOVED SOUTHWARD COINCIDENT WITH LOSS OF DAYTIME HEATING.

AS OF 340 PM EDT FRIDAY...DURING SATURDAY OVERALL PATTERN WILL CHANGE SLIGHTLY TO ONE OF MORE CONTINENTAL CHARACTER WITH LOW TO MID LEVEL FLOW TRENDING MORE WESTERLY AND ANTICYCLONIC OVER TIME. THIS WILL LEAD TO A MODEST WARMING OF OUR AIRMASS WITH NO PRECIPITATION EXPECTED. 850 MB TEMPS CLIMB TO AROUND +6C SATURDAY AFTERNOON...WHICH COUPLED WITH AT LEAST PARTIAL SUN WILL ALLOW FOR MAX TEMPS IN THE VALLEYS IN THE LOWER 70S. MORE OF THE SAME FOR THE REST OF THE SHORT TERM PERIOD WITH CLEAR TO PARTLY CLOUDY SKIES ALONG WITH A CONTINUED WARMING TREND. SATURDAY NIGHT WILL FEATURE LOWS IN THE UPPER 30S TO MID 40S...BUT THEN ON SUNDAY WE CAN LOOK FORWARD TO HIGHS IN THE MID TO PERHAPS UPPER 70S. ONE SMALL CAVEAT FOR SUNDAY AFTERNOON.
