Saturday October 23

The cool temperatures this weekend is just a reality check. Thermometers will be close to average for a few days.  Meanwhile a disturbance may bring some showers this afternoon, and also limit how chilly it may get Sunday morning. So my call for possible frost will not be as widespread.

What will impact all of us will be the track of massive Pacific storms that reach us later this week.  This is a pattern changer and will bring us cold rain.

Morning Surface Weather

A quick moving system is tracking to the Northeast. The better chance for showers will be in the afternoon west and north of Baltimore. But some stray showers may pop up in other areas.

Radar Simulation: Noon to 8 PM

Most of the day will be dry, but there will be showers this afternoon. I will track any developments on the Live Updates page.

Afternoon Temperatures 

These numbers will be close to seasonal averages for this date.

Temperatures Sunday

Morning

Frost may still develop, but it will more likely be farther inland and not as close as I earlier had suggested. We will get there soon enough. 

Afternoon

We will get a little push of milder air…

Looking Ahead

A series of very strong storms is moving off of the Pacific Ocean into the western US. These are monster Bombs with waves over 30 Ft, surfaces winds on the coast over 80 mph, rainfall 5 to 10 inches, and feet of mountain snow.

The track of these systems will reach us next week. That will bring us a few rain events, along with cooler temps.

The most prominent will be at the end of the work week.

This is when we should get the hit from that west coast storm, and possibly with for redevelopment on the coast.

Thursday through Saturday 

A complex pattern of Low Pressures will be worth extra attention during the week. This may redevelop a coastal Nor’easter into next weekend.

7 Day Forecast

The coverage and intensity of the rain/wind at the end of the week will be subject to change with more scrutiny as we get closer.
