Warmer Pattern Sets Up

Discussion: I’m seeing a lot of ridging (see above image) building over the NE US for the next few weeks. This spells a warm pattern that could carry through the first third to half of January 2023. At the lower levels, we’ll likely see a series of high-pressure centers track to the Bermuda area and drive SW flow into NJ. This should push most temps into the 50s for New Jersey and in some cases lower-60s. The first high does it over the next few days and the next high then likely does it Jan 1-4. In-between those periods, we’ll see return flow convergence combine with an approaching warm sector to generate a synoptic rain signal Dec 31 into Jan 1.  So mild and dry for a few days, rain NYE into NYD, then mild and dry for a few more days. It does look to step down cooler for Jan 5-6 but still above average…highs in the 40s/50s rather than lower-60s. Jan 7-8 is the next signal I am monitoring. It would be a thread-the-needle situation in an unfavorable pattern for snow. But hey, we just saw squat from a favorable snow pattern so why not. Looks like a weak trough could scoop up a surface low from the SE US with just enough cold from a high to the N. Other than that, I don’t see much snow possibility through at least Jan 10. But it does look like the cold returns behind whatever happens Jan 7-8.

Wednesday (Dec 28) high temperatures should reach the mid-to-upper 40s for most of New Jersey. Skies should be mixed with sun and clouds. Winds should be light out of the SW. Overnight lows should range from mid-20s to mid-30s from elevations to coasts.

Thursday (Dec 29) high temperatures should at least reach the upper-40s for most of New Jersey, maybe even low-to-mid 50s along the coastal plain. Skies should be mixed with sun and clouds. Winds should be light out of the SW. Overnight lows should range from upper-20s to upper-30s from elevations to coasts.

Friday (Dec 30) high temperatures should reach the low-to-mid 50s for most of New Jersey. Skies should be mixed with sun and clouds. Winds should be light out of the SW. Overnight lows should range from mid-30s to mid-40s from elevations to coasts.

Saturday (Dec 31) high temperatures should reach into the 50s for most areas. Some CNJ SNJ areas might flirt with 60. Clouds should build early and rain should eventually move in by afternoon-evening. Periods of rain are then expected during overnight hours which could impact events like the ball dropping/outdoor parties/etc. If that impacts you, then you might want to consider an indoor audible if possible. Winds should be light-to-breezy out of the S. Overnight lows should fall into the 40s as rain continues into 2023.

Sunday (Jan 1) high temperatures should generally range from 50-60 from elevations to coasts, maybe low 60s for SNJ. Skies should remain mostly cloudy with periods of rain ending sometime during AM hours. Should taper off by noon for all areas. Skies should then improve with a mild feel. It will probably feel like spring. Winds should be light-to-breezy out of the W. Overnight lows should fall into the low-to-mid 40s for most of New Jersey

The long-range look indicates temperatures staying above average for at least the first week of January 2023. Jan 1-4 looks like the warmest it will get (temps breaking 60 for many areas). Jan 5-6 looks like a step-down to just 40s/50s. Then Jan 7-8 is the next possible wintry storm signal I am casually monitoring. There are some more details in the above discussion but we are a long way away. I only recommend following it from this range if you’re a weather nerd like me. Otherwise, enjoy the milder weather and the break in energy utilities that goes along with it. I’ll check back in on Thursday or Friday if anything has changed for NYE/NYD rain. Be safe! JC
