October 16 Frost Advisory In Place And Remaining Chilly After Snow Fell In The Nearby Mountains

October 16, 2024

Wednesday Morning Report

While the chilly winds have brought Fall into full force this week, they also opened up snow showers over the higher mountains to our west. As the winds settled down overnight, the Frost Advisory was expanded into more of Central Maryland just outside of Baltimore.

We may have one more repeat into tomorrow morning as the core of this cold air is overhead. Then we will get the rebound bounce to warm us into the 70s this weekend.

Snow Yesterday

Snowshoe, WV

There was more snow and stickage at 4,848 FT.

Deep Creek Lake

My friend Kim Smith captured a brief heavy burst in Western Maryland.

FIRST FROST

Here are the average dates across Maryland, which line up on schedule with the advisory in place this morning.

Frost Advisory In Place

Morning Temperatures

Morning Surface Weather

A large area of High Pressure is expanding to the entire Eastern US. There are a few upper level disturbances bringing some additional clouds and showers across the Great Lakes, North Carolina, and into northern Florida. Those disturbances are reinforcing the cold, and we will get in on that today.

The return flow on the Western Side of the High will warm up the atmosphere and shift our way this weekend.

Morning Temperatures: Eastern US

Cloud Forecast 8 AM to 8 PM

The clouds will build up quickly this morning and dominate the day especially in the western and northern hills. This breaks up across central Maryland and to the Eastern Shore to a partly cloudy sky.

Snapshot at 4 PM

Winds at 4 PM

Gusts up to 25 mph.

Afternoon Temperatures

A chilly day with most areas remaining in the 50s.

CLIMATE DATA: Baltimore

TODAY October 16

Sunrise at 7:18 AM

Sunset at 6:26 PM

Normal Low in Baltimore:  46ºF

Record 30ºF in 1876

Normal High in Baltimore: 68ºF

Record 90ºF 1897

THURSDAY OCTOBER 17

Morning Low

I expect a repeat of the Frost Advisory, which may include even more counties.

Afternoon High

Surface Weather Wednesday to Saturday

Snapshot Thursday

Low Pressure will rapidly develop off the east coast from this cold air mass forcing a spin along the cold front. This will help to increase the wind from FROM the North and reinforce the chill.

Looking Ahead: Jet Stream: Wednesday to Saturday

The core of the cold air will swing off the coast and allow a warm up to shift our way into the weekend.

Tropical Outlook

Over the next 7 days, there is a 50% chance for something to develop in the open Atlantic. This is a region that is favorable this late in the season, but also more likely to clip the Caribbean and then stay off the East Coast.

There is a another area with a lower chance in the far western Caribbean but not a threat to the US.

7 Day Forecast

Temperatures remain cooler than average for a couple of more days. There is a chance for frost one more time tomorrow.

This weekend looks like a nice warm up again back to the 70s with sunshine.

RESTATING MY MESSAGE ABOUT DYSLEXIA

I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region.

One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. 

There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
