Sunday Evening October 25 2020

This is the time of year for abrupt changes in weather. Baltimore was at 77ºF on Saturday (2 PM), then 24 hours later was sitting at 48ºF.  But we have something even more impressive to look at.

Developing Tropical Storm Zeta is expected to become a hurricane, and follow a path similar to what Hurricane Delta just made two weeks ago. This will get greeted by part of a snowstorm and send heavy rain our way. It may also reinforce a pattern for more storms in winter ahead.

Storm Set Up This Week

Snow and Hurricane Zeta will not completely collide, but some of the energy will merge and head our way.

October 25 Snow and Hurricane Zeta Forecast



I know this may seem early to talk snow, but it is happening today and will play a role in our upcoming weather. I assure you this is not click bait. Let’s take a look first at the snow, then Tropical Storm Zeta.

Record Snow Cover

This morning the analysis showed 19.2% of the US covered in snow. This is a record for the date.

More Snow Forecast

Here is the European ECMWF Model forecast for more snow this week.

Denver was getting snow today, and the local forecast for the city was up to 8 inches of new snow.  The mountains and places to the south into the Texas Panhandle will be in the 1 to 2 foot range, expanding the snow map.

Now, Tropical Storm Zeta

If you are not familiar with the Greek Alphabet, this is only 6 letters deep. There are plenty more before we run out of room.

The winds are up to 50 mph, but this is forecast to reach hurricane intensity before reaching Mexico. A Hurricane Warning is in place for Cozumel. Sound Familiar?

Familiar Track

This has been a year of atmospheric memory to the extreme. There have been 6 named storms that hit Louisiana, but two in particular stand out with a similar track.

Compare Hurricane Laura and Hurricane Delta’s path to what is forecast for Zeta.

National Hurricane Center Forecast 

Landfall is expected to be by Wednesday morning. While the forecast is expected to reach hurricane intensity, it may weaken a little before landfall on the Louisiana coast. This would be the 7th named storm they have this year!

Forecast Putting This Together

The energy from the snowstorm will bring wintery weather into north central Texas. The snow will NOT combine with Zeta, but the energy will feed into the back side. This will speed up the path our way and help dump out heavy rain.

The original Low may pass to our west, and fade over Ohio/West Virginia. But a classic transfer of energy to the coast could reform a new storm there. This would happen Thursday afternoon into Friday morning to enhance our rain.

Zeta Forecast Path (reminder)

The original Low should be to our west by Thursday afternoon. We will get moderate to heavy rain by then. Now compare to the GFS Model animation below.

Watch the bottom left side of the map for the Tuesday afternoon start time. The animation shows the push of the developing storm and new coastal Low near us late Thursday and Friday.




How Much Rain?

Here is a look at the ECMWF Model forecast through Friday evening.  Some of this includes rain we had today. But look for a 2 inch rain event is well within the possibility later this week.

My Thoughts

I believe we already have the pattern set to deliver many storms out of the Gulf of Mexico this winter. That would be a change form last year for sure.

Will that mean more snow? It depends on the track of the Low. I will explain this further in another report.  However, it gives us an active pattern with the potential should there be cold air in place. That will be the battle between a typical, La Nina (warm) and North Atlantic Blocking (cold).


If you have Faith in the Flakes, this keeps the hope for snow alive.  But I would NEVER promise anything this early.   I will be adding this to my overall Winter Outlook to be shared with you soon.
