July 19 Weather: Morning Rain Has Improved The Air Quality

July 19, 2023

Wednesday Morning Update

The good news is the improved air quality today. We can thank a few bands of rain overnight and a shift of winds to help push the smoke away. These showers are along a stalled frontal boundary. This will remain close and may ignite more this evening and rain on Thursday night.

More good news: This weekend is looking dry and less humid.

Morning Radar Recap

A band of rain, including thunder crossed metro Baltimore between 3:30 AM and 5 PM.

6 AM Snapshot

More rain setting up behind the early band will be near and mainly south of metro Baltimore into southern Maryland and Delmarva.

Morning Surface Weather

The morning storms have been along this cold front. That may continue to send impulses this morning. Mid-day may improve with some sunshine, but we could watch this cold front stall and provide more pop-up showers late afternoon and evening.

Radar Simulation 8 AM to 8 PM

The morning rain will move out and fade.

We should be dry before lunchtime. Then we will watch for pop-up showers from mid-afternoon to evening.

I need to restate: I do not trust the precision of these short range models!

Got Plans? Keep A Cautious Eye

I have an evening group bike ride planned between 6 PM and 8 PM. Comparing these two models below and we can see a notable difference in projections for evening storms. Neither is perfect, simply a suggestion.

8 PM Snapshot NAM 3 Km

This model shows a couple of spotty light showers.

8 PM Snapshot HRRR Model

This shows stronger thundershowers across metro 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 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.
