October 24 Colder Air Building In For The Weekend The Stormy Pattern And Melissa Update Into Next Week
Friday October 24 2025
The weather map is active and we have a lot expected over the next week.
The short version is that we are stuck in a colder pattern. Temps will remain below average and this may include expanded Frost Advisories tomorrow morning.
A busy storm pattern will set up and could bring us to hits of rain next week. The second one will be the bigger one. That will arrive Thursday and Halloween Friday with heavier rain and colder air.
That is also expected to take Melissa as a major hurricane out of the Caribbean and into the Central Atlantic, missing the US mainland.
The concern for Melissa on Jamaica is real! Later this weekend rapid development may push this to Category 4 or higher with a pounding of heavy rain on the island nation for many days. The rainfall total may be measured in a few feet.
Let’s take a look…

A lot of activity and dare I say a ‘winter look’?
The chilly air has expanded across the Eastern US.
Great Lakes instability will continue to provide clouds and locally heavy band of rain (this time).
A new storm is developing in the Southern Plains and will start the track of a few systems to the East Coast.

Drought Monitor Update
The need for rain has been highlighted and may be underrepresented in some spots.
We need rain.

SATURDAY
Morning Temperatures
The Frost and Freeze Alerts are expected to be expanded to more areas.

Afternoon Temperatures

Looking Ahead:
Storm Forecast: Sunday to Friday
This is the AI Version of the European Model. I highlight that because it does differ from the operational models, but has been performing best, so I will focus on this:
Here we see two systems. One tracking just south and then off the coast mid-week. The second will be with the upper-level cold-core Low. This may bring the rain on Thursday into Friday morning. It will kick Hurricane Melissa out of the Caribbean and into the Central Atlantic.

Friday October 31

Jet Stream: Friday, October 31

Tropical Outlook
Tropical Storm Melissa’s winds have decreased to 45 mph.
The light steering winds will allow a stall and crawl over very warm water. This will encourage rapid development to major hurricane intensity.
There is ample warm water that runs deep, so upwelling is not expected to be a factor for cooling. Essentially, there is plenty of energy for this to feed off.

More Detailed Look: Thanks to Tomer Burg
This is expected to become a Category 4 Hurricane later this weekend as it stalls or crawls to the south side of Jamaica.

Model Forecast Intensity

Computer Model Forecast Tracks
These all show the kick out into the Atlantic and close to Bermuda… but NOT a US mainland storm. Our local storm and push of colder air will protect us.

Rainfall Forecast: Only Out To 3 Days
Heavy rain may be enhanced even more over the mountains on these islands. The final total could easily be double or triple this over Jamaica and the Turks and Caicos.

7 Day Forecast
- Today: Cool Wind And Inland Clouds
- Frosty Mornings With Daytime Sun
- Temps REMAIN Below Average
- Sunday: Chilly For The Ravens Home Game
- Next Week: Pattern Change Brings Rain

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 can also 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
