Monday Morning Update
Do you remember the record high temperature on Friday? Baltimore’s BWI tied the mark of 96ºF set in 1939. Well, this morning BWI dropped to 52ºF, tying the mark set in 2005. Not as long standing, but once again resetting the clock.
There have been quite a few times spanning the record books when we get extreme high and low temps within a few days of each other.
Low Temperatures Monday Morning
Record Low: 52ºF at Baltimore’s BWI also set in 2005
Today is the Juneteenth Federal Holiday and the weather will feel more seasonable for us. There will be more clouds, especially on our west side, which is a hint of what is on the way…
Yesterday I mentioned the mid week heat wave was in question. It now appears very likely that the heat dome will remain to our west while we get in on rain, storms, and a maritime patter into the second half of the week.
Morning Surface Weather
We can see a band of rain from the Great Lakes reaching the mountains of western Maryland.
Metro areas are on the edge of the high clouds, while the beaches area safely dry (for now).
This banding of rain is something to watch for as the next wave should shift over metro areas on Wednesday when we get our pattern change.

The question has been answered…
The GFS Model I mentioned in yesterday’s report was on to something. The heat dome will remain in the southern and central US, and WILL NOT REACH US.
We will watch another cluster of rain and storms on Wednesday, then a Maritime Air Mass will move westward and reach us. The result will increase our humidity and daily storms. In that patter, temperatures will be more stable in a smaller range… but also feel muggy.

GFS Model: Tuesday Afternoon to Thursday Afternoon

Based on the evidence and trend, that heat wave will not reach us. Rather, the maritime air mass will push our way and enhance the chance of daily thunderstorms. That pattern is uniform, meaning similar temps expected each day. However the daily storm locations and timing may vary.

*Disclaimer due to frequent questions:
I am aware there are some spelling and grammar typos. 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 at my second year at Cornell. I didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region.
I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse.
All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline.
I accept this and perhaps proves what you read is really from me…
It’s part of my charm.
