November 21 Mild Day Rain Tonight Colder Tomorrow And Maybe Flurries Tuesday

Forecast

Sunday November 21

The main theme over the next week will be fast moving systems with reinforcing hits of cold air. Also the weather systems will be arriving late in the day and mostly overnight with rain.

Did you hear last week about a big Thanksgiving week storm? I stayed out of the conversation because I’ve seen a consistent error with modeling storms more than 1 week away.

However, there is a small chance for some excitement in the form of snow flurries on Tuesday. No travel impact locally. I’ll explain below. 

Morning Surface Weather

High Pressure is still in control. If you have morning sun, it will fade behind increasing clouds. Temps will be mild ahead of the next front, which will arrive tonight. 

Rain may sneak into western areas late in the day, but most of us get it overnight. 

 

 

Morning Temperatures

Chilly, but not as cold as yesterday.

 

What to wear?

If you have plans outside, wear layers to stay warm.  You might want gloves and a hat this morning, and a warm coat all day. 

 

Afternoon Temperatures

Afternoon Temperatures

 The high temperatures may be mid day, then falling in the afternoon. It will be cooler at the end of the day.

 

 

Tuesday:

This is a deep dive up high. We need to look at the jet stream to see if we can get Lake Effect snow to cross the mountains. 

Vorticity is a measure of spin around 18,000 Ft up. This can give added lift in the clouds to allow the clouds and showers survive over the mountains. 

Snapshot: 

A trough will wing through late morning to early afternoon. There will be some sort maxes marked with an ‘X’ pivoting through that could help produce some snow flurries across the region. 

 

 

Tracking Snow

This plot misses the precipitation that will not accumulate. So flurries are very possible even when not shown.
