October 12 Isaias moves followed by a few hot days

Monday morning report October 12

Thanks for reading this article, don’t forget to subscribe!

The REMAINDERS of Isaias certainly exceeded their goals. Although we had our 5th consecutive soggy Sunday to validate the forecast, the rain totals exceeded our expectations. I realize that maps of rain totals differ significantly. Radar estimate is underestimated, while a Maryland Mesonet product resets at midnight. I will have an official final tally later this morning.

The latest cards are below.

Low pressure is off the coast and will bring with it morning rain, followed by gusty winds and clearing today.

The next few days will warm into the 80s, setting up a dramatic fall with the next cold front. The upcoming weekend will be very cold and could bring the first frosts to parts of central Maryland.

Let’s take a quick look.

Rain total maps

Radar estimate

(I know some places in central Maryland received 3-4 inches of rain).

Maryland Mesonet: SINCE MIDNIGHT

More than 2 inches of rain has fallen SINCE MIDNIGHT in parts of Cecil and Kent counties.

The low pressure that was once Hurricane Isaias is located off the coast. High pressure and a few warmer days will arrive.

REPRESENT MY MESSAGE ON DYSLEXIA

I am aware that there are some spelling and grammatical errors and other occasional issues. I take responsibility for my mistakes and even computer problems that I might 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 discovered it during my sophomore year at Cornell University. That didn’t stop me from getting my degree in Meteorology and being the first to get the AMS CBM in the Baltimore/Washington area. One of my teachers told me that I had come this far without knowing it and that I should not let this be a crutch for the future. It was Mark Wysocki, and he was absolutely right! I miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice and makes the situation worse. I can also make mistakes in the forecasts. No one is perfect at predicting the future. All maps and information are accurate. “Wordy” stuff can get sticky. No editor can check my work while writing and ready to send in a newsworthy schedule. Barbara Werner is a member of the web team who helps me maintain this site. She has taken it upon herself to edit typos when available. This could be AFTER reading this. I accept this and perhaps prove that what you read really comes from me… It’s part of my charm. #FITF
