Friday July 17 2020

It’s my wife’s Shannon’s birthday today. Now that I made sure to mention that, I should add that she is a beach girl and loves summer heat. To which I often remind her to be careful what she wishes for. Today is going to be our first taste of what’s to come and if you are not near water, you will want to be inside in air conditioning.

A few showers rolled through central Maryland this morning. That will add to the humidity and make the building heat more oppressive. I personally am not a fan of heat, but I resave that term ‘oppressive’ for when it gets close to 100ºF. It will feel like that for some today.  After a little break in humidity tomorrow, it all comes pouring back Sunday into next week.

Each day we could get some pop up showers and storms, but the next organized active weather, and break is expected to be Wednesday.

Morning Set Up

Radar Loop: 2 hours 25 minutes ending at 7 AM

Dew Points (at 7 AM)

With these numbers in the 70s, it is very uncomfortable for most people. That is the mark where moisture would condense out and the true measure of moisture in the air.

Saturday Afternoon Forecast

It will remain hot, but we may drop the humidity a little for a day. This will depend on the wind shifting.

Looking Ahead:

Rain Chances

There may be some showers later today, with the focus on southern Maryland. But then the heat dome takes hold this weekend with very little rain risk.

Storms are likely to return next Tuesday and Wednesday. This will provide some brief relief from the heat wave.



Heat Wave

This Bermuda High I keep mentioning is a common summer pattern. It’s been a while since we had one this strong, which may allow it to dominate the rest of the month.

We may get a brief break from it on Wednesday with a cold front and widespread storms. But the long range pattern shows it truing to rebuild. This animation shows us on the edge of the heat next week, so there is a chance the models are not doing justice for an intrusion from New England (back door). If the Bermuda High can rebuild, it will then last to the end of the month.



Temperature Outlook

July 21    104ºF in 1930
