Very Cold Night Ahead Warmer By Sunday Next Weather System Rhymes With Last One
Cold and windy on a November day and we struggled to get back to 40 degrees for an afternoon high. The average high this time of year in NYC is 57 and in Philadelphia it is 59 so we are talking about a solid 15 degrees below average. Seasonally adjusted it is as if we had an average day in late December. Now we get set for a cold night ahead and the last urban area not to see 32 is NYC where a freeze warning is in effect. Lows are headed down into the low and mid 20s by morning everywhere. We have some patchcy clouds on the satellite picture and we should go mostly clear once we pass sunset.
Saturday will be a cold day with sunshine but with less wind and highs reaching into the lower 40s in most places. Warm air will begin to arrive aloft so some high clouds will likely develop at some point during the day. That should keep temperatures higher Saturday night with most lows in the upper 20s to mid 30s by Sunday morning.
Sunday temperatures should bounce higher on a southwest wind with highs in the upper 40s well inland and north to the low an mid 50s everywhere else. Temperatures have to reflexively rebound back toward seasonal averages between air masses but we will still be below average
The next arctic boundary begins its approach on Monday which will put us in clouds and some breaks of sun with highs in the 50s. Weather models were struggling with whether the wave goes by first or does the cold air come and then the wave goes by bringing an early season snowfall.
This system rhymes with the one that came through yesterday where the precipitation arrives first and then leaves as the next shot of arctic air arrives. Snow lovers could have guessed this would be the outcome. Rain arrives late Monday night and then ends Tuesday afternoon. This system might have some more punch to it regarding snow for Upstate NY and for Central and Northern New England. I suppose you can argue that there could be a brief cheap thrill for snow lovers when the rain ends Tuesday afternoon.
Then we are back into the November ice box. The map above is preliminary look at the forecast lows for Wednesday morning. Lows will be in the teens inland and low to mid 20s along the coast. Highs Wednesday afternoon will likely not get much above the low and middle 30s! Cold air will remain with us into Thursday and with the next high likely going out or north, the recovery will be a bit slower. Also late next week sees a low coming out of the Gulf of Mexico and heading northeastward for late next week or next weekend but by then the cold air will be long gone.
