Wednesday, August 21 2024

Morning Report

The core of the cool air with this air mass has settled in. Yesterday, Baltimore had a high temperature of only 75ºF, which was 11 degrees below average. We may have one or two more afternoons in the 70s ahead.

Sunny and dry weather will last into the weekend, with a warming trend to bring back the 90s.

Morning Temperatures 

Many areas in the 50s!

The 40s dominate from Frederick and WEST to the mountains. Some interior local valleys are in the 40s as well between northern Harford County and York in PA.

Morning Surface Weather

A large area of High Pressure will be taking over the Eastern US. This will bring cooler temperatures and keep us dry through the rest of the work week.

FORECAST Winds

2 PM Snapshot

Winds FROM the North may gust up to 25 mph. This will keep us cooler than average AND make it feel a little like Fall.

Afternoon Temperatures

Many areas remain in the 70s. It is possible that with additional clouds, the northern suburbs of Maryland and Pennsylvania may be in the upper 60s to near 70ºF again this afternoon.

The animation shows the 500mb heights. This is around 18,000 ft and represents the warm and cool air in the atmosphere that responds to how high it is measured.

Here, we can see the influx and established Cool Pattern relaxing to allow a warm-up this weekend.

Saturday Snapshot

A return to near summer temperatures this weekend.

7 Day Forecast

Temperatures will gradually modify back to near normal and then summer heat by the end of the weekend. We are NOT done with the 90s yet.

Note: It is common to get preseason cool spells followed by high heat and perhaps another record high to balance things out.

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
