Breezy Wednesday, a calm Thanksgiving, snow for Friday

11/24/2021

A quick update to start off to say thank you to my new Patreon monthly donors along with those who have contributed via VENMO. Looking at the tally through Tuesday, PTW is 70% funded for the year, for which I am most grateful. This is the third year that I have asked for donations to fund what I do here, and this is by far the best response, thanks to those who have stepped up. That said, I am short $900. If you have not contributed yet, please consider PTW with your annual holiday giving. You can click on the banner below or the DONATE page from the menu for details.

Thank you for your words of encouragement, and for passing along to others what I do.

A brisk Wednesday

Another breezy day means apparent (feels like) temperatures will be 5-10° cooler than actual thermometer readings. Any morning clouds over the mountains and north clear out by midday. High pressure settles in, the breeze slacks off and cold night is on tap ahead of the holiday.

I keep mentioning about snow tires. I've been saying periodically here that repair shops are booked solid. Since I am in the commercial vehicle end as my primary income, I talk to other repair facilities locally and in the northeast and they are booked solid, dealing with shortages on techs and parts. There are rumblings that when the first big snow hits that the new snow tire supply could evaporate quickly. The annual meeting of the summer tires club with the first widespread impactful storm could see several other gatherings over the course of the winter given the situation. For the procrastinators, it's time to get on the stick and book an appointment.

A quiet Thanksgiving

Wednesday 7 PM to Friday 1 AM - High pressure settles the wind and controls the holiday. The sky looks mainly clear. Temperatures warm up from the chill of the previous two days into the 40s and 50s. Our next storm organizes itself over the Great Lakes and approaches the region for Friday.

Snow for interior areas for Black Friday

Friday 1 AM to Saturday 1 PM - This loop provides an idea of 1-hour snowfall accumulations. The mountains and north appear to be the chief benefactors of the frozen precipitation, with the coast deals with rain. There could be some mixing of snow and rain over the coastal interior on up into the foothills. Snow appears to be of the heavy and wet variety during the day, then loses water content and becomes drier and accumulate more heading into Friday night and early Saturday.

The first call for snow amounts shows the interior areas receiving a manageable amount to start off. Where I may make an adjustment is over eastern areas as models keep toying with an idea of low pressure forming over the ocean along the front. Timing and intensity will dictate whether snow amounts may increase there, but the jury is out on that thought for now. I will monitor and update on that.

Spurts of cold and chances for precipitation
continue into early next week

Saturday 1 AM to Monday 7 AM - For those who caught my Monday afternoon Facebook post I noted on the graphic of the slip stream, and here you can see it in action. This is the 500mb level which is the steering pattern. The blues and greens indicate troughs and the yellow, orange and reds indicated ridges. There is some deep cold over northern Alaska, Yukon and Northwest Territories that will spill to the southeast and head our way. The troughs that form and their location of axis will dictate chances for precipitation for the region.

As the leading trough departs to the north Saturday into Sunday, another one tucks itself in underneath of it. A storm is expected to generate over the Mid-Atlantic region Sunday, then head out to sea Monday. It may be close enough to produce snow showers along the coast. If the trough is a bit weaker and further north, then that would increase precipitation chances further inland. Stay tuned for updates on that.

Ice and Snow, Take it Slow

Temperature outlook through Monday

After a warm Thursday, temperatures cool down heading into the weekend. With the forecast snow and cold temperatures, the ski hills will be able to make snow and start building the bases.
