September 25 Cool And Wet Again Today The Rain From Helene Friday

Wednesday September 25, 2024

Morning Report

This wet weather pattern continues. The roads are likely wet, and the fields are damp or soggy for after-school sports. There will be more steady rain today, with a mix of drizzle and fog. There will again be heavier thunderstorms in the mountains.

Tomorrow should give us a break with a brief warm-up, and then more rain arrives on Friday. This will be from Helene after making landfall in Florida, but we will remain very far away from that storm. It will help influence more showers each day into next week.

Much of the Eastern US is under the influence of low clouds, drizzle, and showers. The steadier rain and thunderstorms will be more active in the mountains and try to spread east later today.

This morning, winds were 65 mph, and it was located near Cozumel and Cancun in Mexico. Once entering the Gulf of Mexico, it is expected to become a hurricane later today. Then, it is expected to rapidly develop into a Category 3 before landfall in Florida tomorrow night.

Thursday Through Saturday

Here is a wide-view look at what is expected to be Major Hurricane Helene hitting Florida tomorrow night with winds of over 110 mph. The upper-level system I mentioned yesterday will help pull the Low North and Northwest into the Ohio Valley.

While the main storm will miss us, the surge of a plume of rain will arrive in the Mid-Atlantic by Friday afternoon. Then, a stalled pattern will keep an East Wind with showers in place for many days to follow.

SNAPSHOTS

Friday Afternoon 

The rain from Helene that pushes up the East Coast will reach Maryland. It is important to note that the remnant Low of Helene will be somewhere in the Ohio River Valley.

Saturday Morning

The remnant Low of Helene will be stuck in the Midwest, and we will remain with an unsettled, damp pattern. Showers and an easterly wind will continue for a few days.

Rainfall Potential Through Sunday

There may be more rain in addition to this into early next week.

7 Day Forecast

One warmer day near 80ºF on Thursday, then we need to pay close attention to some tropical rain showers that may arrive Friday into Saturday.

A sustained cloudy, cool, and wet pattern with ‘showers’, not steady rain, is expected to last into next week.

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
