May 4 2020

The only way to do this is to give it straight! May the 4th be with you today, but May The Flakes be with some on Wednesday. It’s going to get cold enough this week for snow in western Maryland, more rain for most of us, and some possibly inland frost next weekend. So if you didn’t plant your garden yet, you made the right move.

Jet Stream Pattern

This is a look at the upper air pattern mid week, and it will look like this through mid month. Here is a weather pattern that we expected in winter, and if that happened we would have had epic snow. To have it in May just delays spring. See this animation and the outlook below.


Back To Today’s Weather

On its face, today will be nice. Blue sky and sunshine, with temps in the mid to upper 60s. But a cool breeze will build up to 30 mph this afternoon. This will be the nicest weather day of the week.

Rain On The Way

Tuesday will bring rain across mountains that will try to spread our way by afternoon. Some mixed precipitation in the highest mountains, but wait…

Wednesday brings in the colder air and more rain. This is the day that we will really feel the cold pattern establish itself.

Snow is likely in the western Maryland, VA, and WV mountains, with some stickage above 2,000 Ft elevation. Some flakes may also fly over the northern Catoctin Ridge near Thurmont Maryland and Liberty Mountain in PA.

A chilly rain for the rest of us.


Wednesday Temperatures

Much of our region will be in the 10 to 20 degrees cooler than normal. That translate to upper 40s and lower 50s. But closer to 30 degrees below normal in western Maryland with the snow risk.


Rain Animation Through Mothers Day

Rain Day: Wednesday.

Some afternoon rain showers possible this weekend. Notice the snow in northern PA and central New York. There will be places with accumulation.


Chilly Weather Pattern

This weekend, colder air is expected. This is the temperature departure on Saturday Afternoon. This is a colder push that on Wednesday!  While we will notice it most during the day, it will be both weekend mornings we need to watch for possible inland frost and record cold temps.

Jet Stream Through Mid May

This animation shows the cold (blue) pattern continuing through May 16. That is the weekend after Mother’s Day.


Temperature Outlook

Here is the BLEND of models. Often when we get an extreme pattern, the models have trouble identifying how cold (or warm) in the longer range. That is why the potential for more frost with colder air next weekend is possible.
