Tired of warmth? Now for many kinds of weather, each completly different!

The chill in the air today seemed more normal.  But today’s temperatures in the 40s were still ten degrees above normal.

Sunday’s weather will remind us of summer again, but Tuesday morning we’ll have to be ready for frozen precipitation before the morning rush.

First the hot news… from the National Weather Service forecast discussion about the possibility of a new round of record setting temperatures on Sunday…

ANOMALOUSLY WARM AIR WILL ADVECT INTO THE REGION UNDER A INCREASING SW WIND. THIS ALONE WILL HELP DRIVE TEMPERATURES TO NEW HIGH TEMPERATURE RECORDS FOR 27 DECEMBER. SEE CLIMATE SECTION BELOW FOR CURRENT RECORDS FOR THIS DATE. WITH THE SW FLOW OFF THE RELATIVELY COOLER OCEAN…TEMPERATURES NEAR THE COAST WILL STRUGGLE TO RISE MUCH ABOVE THE LOWER 60S. NEAR THE NYC/NJ METRO…READINGS SHOULD APPROACH 70 DEGREES. INLAND LOCATIONS SHOULD REACH THE LOWER AND MIDDLE 60S. IF THERE ARE MORE BREAKS IN THE CLOUDS…READINGS COULD BE EVEN WARMER. IT SHOULD BE NOTED THAT THE 12Z MAV GUIDANCE FORECAST THIS WARMER SCENARIO WITH TEMPERATURES AT EWR REACHING 75 DEGREES. DID NOT GO THIS HIGH DUE TO THE EXPECTED CLOUD COVER…BUT IT IS NOT OUT OF THE QUESTION TO SEE TEMPERATURES WARMER THAN CURRENTLY FORECAST.

Then a real Canadian high pressure system will push into our area on Monday with the first day of the month at Central Park with below normal temperatures.  The cold air hangs on long enough to have some snow and other frozen precipitation Tuesday morning.

WITH THIS IN MIND…FOR INLAND SECTIONS HAVE FORECAST MAINLY SNOW/SLEET AT THE ONSET MON NIGHT…CHANGING TO FREEZING RAIN/SLEET WELL NORTH/WEST OF NYC…AND THEN RAIN BY LATE MORNING OR MIDDAY ON MON. AREAS CLOSER TO THE COAST SHOULD SEE MORE IN THE WAY OF RAIN…BUT BEGINNING AS A PERIOD OF MIXED PRECIPITATION. MOST LIKELY SCENARIO IS FOR ABOUT AN INCH OF SNOW/SLEET ACCUMULATION WELL INLAND…TO A COATING OF ACCUMULATION FOR AREAS JUST NORTH/WEST OF NYC AND ALONG THE CT COAST…TO NO ACCUMULATION FOR NYC/LONG ISLAND. AREAS WELL INLAND MAY ALSO SEE UP TO A TENTH OF AN INCH ICE ACCUMULATION…MOSTLY ALONG THE I-84 CORRIDOR AND ALSO IN NORTHERN REACHES OF NEW LONDON COUNTY CT.

Well north of NYC may see an inch of icy stuff, which may wash away before the morning rush, so check for updates on Monday on the timing of the slippery stuff.

Then we get a brief period of fair weather on Wednesday, followed by more wet weather later Wednesday into New Years’ Eve.  Drier and colder New Years’ Day. Maybe then we’ll have some better weather for astronomy!
