Tuesday morning report

The moisture left over from yesterday’s rain and the unclear situation ahead of the next storm have caused the moisture to condense into thick fog. Imagine a mostly cloudy sky above but at ground level. Some places may not be bad, but in many places visibility is very poor, even close to zero.

This fog will last longer and keep our temperatures cooler.

The warm-up will come with rain overnight and then we will see the lower 60s with heavy rain for most of Wednesday.

While this could end with some snow inland, the focus will be on the heavy “necessary” rain and the subsequent falling temperatures.

NOTICE ABOUT THICK FOG

This lasts until midday in central Maryland. Visibility will be less than half a mile in many places throughout the morning.

It will end by 9am across much of the rest of the region, but poor visibility may last longer.

REPEATING MY MESSAGE ON THE TOPIC OF LEGEND

I understand that there are some spelling and grammatical errors, as well as occasional other errors. I take responsibility for my mistakes and even the computer errors I may miss. I’ve made a few public statements over the years, but if you’re new here you may have missed it: I have dyslexia and found out about it in my sophomore year at Cornell University. However, that didn’t stop me from getting my degree in meteorology and being the first to receive the AMS CBM in the Baltimore/Washington area.

One of my professors told me that I had made it this far without knowing it and that I shouldn’t let it be a crutch for the future. That was Mark Wysocki, and he was absolutely right! I miss my mistakes when proofreading myself. The automatic spell checker on my computer sometimes misses the mark and makes the problem worse. I can also make mistakes in forecasting. Nobody is perfect at predicting the future. All maps and information are correct. The “wordy” stuff can get sticky.

There was no editor to review my work when writing and have it ready to ship in a newsworthy time frame. Barbara Werner is a member of the web team that helps me maintain this website. She has made it her mission to correct typos when available. That could be AFTER you read this. I accept that and perhaps prove that what you read is really mine… It’s part of my charm. #FITF
