Well, this morning we wake up and it is not nearly as Windy at the surface. However it is quite windy just above the surface where winds are easily gusting to 50-55 mph about 2-5000 feet up.
Now with winds busy aloft and not at the surface as much there now is the possibility that some of the snow streamers coming off of Lake Erie and Ontario could make it further south and east towards the Delaware Valley. They are already or have already visited the Lehigh Valley this morning
If and when any snow showers or light rain showers does visit your area again like I said yesterday they can tap into the 50mph wind aloft and bring them to the surface and also the colder air towards the surface to keep any precipitation today mainly snow if and where it occurs today.
The band I have circled in red has the best chance of holding together as it moves east-southeast this morning. This band could produce a quick burst of snow but it should not stay in any one place for long. I am not expecting accumulations for the most part just a reminder that it is February 25th.
I would give this band a 60% shot of holding together Reading to Willow Grove
I would give this band a 40% shot of holding together Coatesville Chester County to Radnor Delaware County
Points Elkton Md to Philadelphia south and east about a 30% shot of having that band in red holding together
If you do get hit with that band it could look impressive for about 10-15 minutes especially points north and west.
It's snowing moderate to heavy in Gwynedd, PA right now and the snow is sticking to just about everything. The sun will probably be out in about one-half hour. Enjoy because it's probably one of the last times we'll see snow this season.
I am growing more and more confident that the Lake Effect Snow Band that extends from Pittsburgh over to Reading to about Trenton NJ will most likely make it through most of the area between now and say 1PM.
Looking over things here there is most definitely things going for this band:
1. Lapse rates look pretty good.
2. There most certainly looks like there is a boundary with this
3. Winds aloft and stronger than at the surface which should diminish evaporation rates
4. Cold air aloft will keep this all snow no doubt!
What to expect:
Very Strong Gusty winds to near or just past 50mph
Brief Heavy Snow and blowing snow
A small accumulation at this time cannot be ruled out
YOU GOTTA TREAT THIS LAKE EFFECT SNOW STREAMER ALMOST AS IF IT IS A LINE OF THUNDERSTORMS ON A BOUNDARY IN LATE SPRING OR SUMMER TIME
