Starting out with the satellite this evening, we remain in a flat and zonal weather pattern , with a strong upper level low in the Gulf of Alaska forcing a strong Pacific jet stream into the US so our flow is west to east across the whole country with no amplification what so ever , kind of like last year around this time.
You can also see we have a coastal storm, it was a close call but with the zonal pattern in place its being kicked due east out to sea
This pattern is expected to remain in place through Friday so it’s a pretty simple weather forecast this week, dry and seasonable
From now Through Thanksgiving Thursday temperatures will be pretty uniform, and not change really much at all . This coastal low will linger there and keep us in more of a Northeast flow , which means we will not see much of the warm Pacific air that is flooding the country
Highs each day will be in the mid 40s NE PA to low 50s along the coast, lows in the upper 20s NE PA to mid 30s to low 40s along the coastal plain
Friday a cold front will drop southeast from the Midwest, we will warm up ahead of this cold front as winds change more west and southwest, very briefly we will warm to above normal levels, highs in the low 50s NE PA to mid to upper 50s along the coastal plain
By Saturday morning the cold front is coming through, you can see very cold air behind this front
So on Saturday look for highs in the low 40s NE PA to upper 40s along the coast , the real cold air drops in Saturday night with lows in the lower 20s NE PA to upper 20s and low 30s along the coast and Sunday everyone will struggle to touch 40 , even along the immediate coast , highs in the low to mid 30s NE PA to upper 30s to low 40s along the coast with lows again in the 20s area wide , highest elevations of NE PA could drop to the upper 10s
Looking in the longer range, this cold shot will be very transient and we will begin to warm up again by Monday
You can see we still have that upper level low in the Gulf of Alaska ao our pattern will remain zonal and progressive so next week we will warm up again to seasonable to even above seasonable temperatures.
There are signs of this pattern changing to a more amplified pattern , but it looks like if it does happen , it’s going to take quite some time, so for the foreseeable future expect quiet weather conditions and overall averaging seasonably cool through the end of November and into early December. I’m not going to start hyping up this big pattern change and fall into the same trap I did last year when it never happened
