December 15 Still Cold With Less Wind Then Warming Ahead Of Rain Later This Week

Monday Morning December 15, 2025

Today starts off cold, with areas of black ice forming due to blowing snow and refreezing overnight. While there is a breeze and wind chill to contend with, the winds will ease, and eventually we will warm up during the week.  This will be ahead of the next storm to bring rain Thursday night and Friday morning.

Note: I posted the final snow report last night, but there was an error in my map, which didn’t account for the snow in Southern Maryland and Delmarva. That has been corrected below and in my report.

HEADLINES

• Very cold morning with wind chills in the single digits and lower teens

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
