April 21 Chilly Sunday With Rain South And Frost Inland Overnight

Sunday, April 21

Morning Report

Today there is a storm system passing off the coast of South Carolina. This will clip Maryland with rain mainly south of Annapolis. However, this will keep the clouds and chilly air in place. 

Local folklore says to hold off on planting until after Mother’s Day. Despite the warm April so far, we will experience a below-average pattern for the week ahead. This will include inland frost overnight and perhaps again during the week.

Morning Temperatures 

Chilly start with cloud cover and a storm passing to our south… we will remain chilly today. 

Morning Surface Weather

Low Pressure is tracking off the South Carolina coast, spreading light rain north into the mid-Atlantic. It is expected to reach as close as Anne Arundel County midday, perhaps near Annapolis. The better chance for rain will be farther south, with dry weather near and north of Baltimore.

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
