July 15 Hot and Humid With More Storms Tonight And Sunday

July 15, 2023

Saturday Update

There is an old cold front that has stalled and is fading across our region this morning. We remain warm and humid but have very ambiguous triggers to ignite storms today.

We are still in a drought, with parts of Maryland missing out on the recent round of rain, and a severe drought remains in parts of Carroll and Frederick Counties. So any rain will help.

We will get some pop-up showers this afternoon, then more numerous storms tonight into Sunday morning. That will set up areas of fog and more humidity to give us a more active Sunday.

Morning Surface Weather

The old front that is dissipating is located right over central Maryland. The next influence for more widespread rain will come from a weather system in the Ohio Valley… Arriving on Sunday.

Afternoon Temperatures

Another hot day with humidity resulting in a slightly higher Heat Index.

Radar Simulation 2 PM to 10 PM

SUGGESTION: I DO NOT TRUST the short-range modeling.

The idea here is that there will be some pop-up showers. It is impossible to pinpoint specifics in this setup. Just keep an eye out for anything near you.

The mountains will help develop more late day storms, which will carry east into metro areas this evening and tonight.

10 PM Snapshot Suggestions

An increased chance for more rain this evening and overnight.

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 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.
