Discussion: First let’s talk about tonight. Temps should hold on the milder side and fail to dip below 45 or so. The primary low will generally track along/just NW of the Appalachian Mountains across parts of SE Ohio, W PA, and NY State between now (Thursday afternoon) and Friday afternoon. This should whiten up the E Great lakes but bring rain to all areas SE of such. Most rain for NJ will fall late tonight (Thursday night) through Friday morning and likely as a thinner strip of rain than you would think (like a thunderstorm line). You might see enough convection for boomers with it. But again, that’ll be overnight tonight and likely before Friday morning’s rush hour. The rest of the weekend is colder, breezier, and dry as N/NW winds move in behind the departing primary low. NJ wasn’t that far from a coastal snow storm this weekend. There’s now strong support for a secondary low to occlude off the boundary and develop just out to sea Sunday. As you can see on the below European model, NJ would be about 200-250 miles W of a cold conveyor belt (CCB)-driven snow band.
Looking down the road, we’re in for more above-average temperatures. There are no signs of a wintry pattern returning until about ~Jan 24 at the earliest. We might see some transient cold shots behind events that bring rain or miss (the thread the needle failures) but the milder snow lover’s drought will likely continue until at least then. NAO and AO tellies are expected to go negative around that time frame which will try to back and block up the jet stream from Greenland-upstream. But we’ll still need the E Pacific/W US area (EPO/PNA region) to cooperate with a W US ridge to bring anything snowstorm-wise to fruition on the east coast. That’s what I’ll be looking at over the next few weeks and will report accordingly. For this weekend, we have a rain event tonight into tomorrow and a few cold and dry days after (a transient cold shot) until we return to the milder pattern next week.
Friday (Jan 13) high temperatures should reach the mid-to-upper 50s. Rain should end by mid-to-late morning with improving conditions by afternoon. Winds should be breezy at times out of the W. Overnight lows should fall to near-30 for most areas as winds become NW.
Saturday (Jan 14) high temperatures should max in the upper-30s for most areas. Skies should be mixed with sun and clouds. Winds should be breezy out of the N/NW. Overnight lows should fall into the 20s statewide.
Sunday (Jan 15) high temperatures should reach near-40 for most areas. Skies should be mostly sunny. Winds should relax some out of the N/NW but still light-to-breezy at times. Overnight lows should range from teens to 20s from elevations to coasts.
An early look at next week indicates milder (for January) temps returning. 40s/50s during the day and 20s/30s at night. There are a few long-range indicators and signals for a more wintry pattern returning in the last week of January. But from now until then we’ll probably stay in a snow lover’s drought as above-average temperatures continue outside of a few transient cold shots behind missed/rainstorms. It is what it is. Have a great weekend and please be safe! JC
