May 24 Weather Last Warm Day As Cooler Air Then Rain Arrives This Weekend

May 24, 2023

Wednesday Morning Update

Today will be the last warm day for a while. We still have a smokey haze in our sky, that will get moved out tomorrow.

To our north is a cooler air mass that may arrive with showers to the north this evening. Then to the south is a storm that will bring rain over the holiday weekend.

Temperatures at 6 AM

A cool start to the day, but it will end up warmer this afternoon.

Morning Surface Weather

The smokey haze is still overhead and will dim the sun again. But it will be getting pushed out of here tomorrow. A cool front along the Canadian border will bring in showers from the north this evening and a fresh, cooler air mass tomorrow.

That will be important to watch as it may slow down the arrival of the developing storm in the Southeast US.

We do expect to have that storm arrive with rain by Sunday.

Afternoon Temperatures

This will be our last warm day for a while.

Radar Simulation 4 PM to Midnight

The cold front will arrive from the North by this evening and tonight.

Snapshot at 8 PM

The line of rain and perhaps some lightning will slide into southern PA. This may include York and Lancaster.

Snapshot at 10 PM

The line of rain will reach the Baltimore Beltway, however it will fall apart after sunset.

Smoke Forecast: Animation Through Thursday

The hazy sky will continue today, then clear out with the new air mass tomorrow and Friday.

Wet Holiday Weekend?

Friday to Sunday

The coastal storm forming in the Southeast US will be slowly moving up the coast. Strong High Pressure from the North will suppress that storm.

This will do two things:

• Increase our cooler wind from the East
• Delay the rain arrival until Sunday

Snapshot Saturday

High Pressure may hold longer and help to slow down the arrival of the rain. It will still increase our East wind. The result will be cooler air… especially at the beaches (60s).

Snapshot Sunday

The chance of rain is expected to finally move in. This will be a chilly and soggy time at the beaches and not good pool time inland.

7 Day Forecast

The cooler air will clear out the smoke, allowing for a few dry days. The coastal storm will affect us this weekend, with the rain more likely Sunday and Monday.

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 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 predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.  There has been no editor that can check my work when I needed it and 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 able. 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.
