Good Wednesday morning to you, South Jersey, and Happy Hump Day to you as well! Last I checked, it was November 13th, but if you took a look at a thermometer, it feels like it should be January 13th. Yesterday's cold front has brought with it a strong surge of cold air that has taken hold of the entire Northeast, and while it won't last too long, its presence will be felt in earnest. Our overnight low of 25 degrees almost tied our current record low in EHT of 22 degrees, and we may have another repeat performance of these chilly temperatures tonight. In order to get there, we must first go through what is shaping up to be a cold day in South Jersey. Despite plenty of sunshine thanks to high pressure taking hold of the eastern seaboard, the prevailing northwesterly flow at the surface and further up in the atmosphere will keep things rather chilly down here. Air temperatures may reach the low 40s on the mainland and coast (With our average high for this time of year being 58 degrees), but when you factor in a northwest wind at 15 to 20mph, wind chills will make it feel like it is ten degrees cooler. Needlessly to say, please be sure to dress for the occasion if you're going outside. Our record low for Thursday is 15 degrees, and while I do think it will be just as cold tonight as it was last night, that record should remain safe for another year. Skies remain clear, winds calm down, and the air remains dry. As a result, temperatures will drop well into the 20s once again on the mainland and near 30 degrees on the coast. Winds will be out of the west at 5 to 15mph.
As I said earlier, this cold air pool will be short lived. High pressure begins to drift further to the east on Thursday, and as it does, we will gradually find ourselves on the warmer, western side of this core. Winds will shift from the cooler northwest to the warmer southwest direction over the next few days, and the jet stream will also lift up...allowing for this warmer air to come up from the Southeast and along the coast. From Thursday into and including Saturday, skies will remain partly to mostly sunny thanks to that core of high pressure. Highs will start in the low 50s on both the mainland and coast, but they'll gradually climb back into the upper 50s by Saturday on the mainland and mid to upper 50s on the coast. A stronger surge of warmer air comes into the picture on Sunday and goes right into the start of the work week. It does, however, come at the cost of our pleasant weather. Isolated showers are possible as a weak impulse moves in ahead of a cold front. Otherwise, we should see increasing clouds with highs pushing the 60 degree mark. We'll exceed that on Monday and possibly Tuesday, depending on the speed of this cold front. Either way, the low level jet stream will be strong, so winds may also be rather gusty on Monday and Tuesday as this front passes. Highs will easily reach the low to mid 60s for the start of the work week, but another deep pool of cold air moves in right behind this cold front. Again, timing is key here, and it may be massaged and tweaked over the next day or so.
Stay warm, and have a great day!
