Cold Friday Saturday Warmer Sunday Another Cold Air Mass Next Week
We hit bottom in the mid 20s inland and lower 30s along the coast Friday morning. We are looking ahead to sunshine today with some patchy fair weather clouds. Gusty winds will make it feel like it is in the 20s today while actual air temperatures struggle back to the 40 degree mark. Yesterday’s cold front is offshore. Radars will be nice and quiet day and over the weekend. This is the first of two shots of cold air heading here for the next 5 days. The second shot will be colder than the first.
There are still a couple of odd spots that have not gone below 32 degrees yet mainly around warmer urban centers. That will be taken care of tonight with clear skies. Most lows will be in the 20s with teens inland cold spots north and west of the coast.
Saturday we will start with sunshine but as the core of the cold air moves offshore, high clouds will begin to arrive as warm air moves in aloft. That will hold temperatures down a bit with highs in the upper 30s to lower 40s. We are transitioning to a warmer set up for Sunday with a southwest wind and some sunshine. Highs will reach into the 50s on Sunday.
The next arctic boundary makes its approach on Monday and weakly moves through. To the west another arctic high is moving southeastward into the Plains. This is going to be another situation where a front is approaching with cold air and a developing wave or waves (there might be more than one). The question is whether the wave goes by first with some rain (like last night) and then the cold air arrives after the precipitation is long over with. Or will it be the other way around this time that some cold air comes in ahead of the wave and then the bulk of the cold air comes in behind it.
Weather models overnight were rather uniform now in the idea that the wave goes by first with rain and that any snow would be in Western Pennsylvania to interior Upstate NY and Interior New England. The system also right now looks rather “flat” like yesterday and not a big precipitation producer. We still think the jury is out and would like to wait another day or so to see if there could be some more adjustments. Either way, this doesn’t appear to be a big deal weather wise be it rain or snow and it does turn sharply colder behind the wave regardless.
Longer term this early visit of cold weather (relative to average) with a strong flow from Northwest Canada might relax a bit going forward as we head into late month as we see the atmosphere move around a few of the chess pieces that drive the weather pattern which would be perfectly normal in the scope of things.
