July 17 More Humid Today Severe Storms Monday Then Big Heat Wave Builds In

July 17 2022

Sunday Morning Update 

Before we get started, I want to say this is a very special day! Today is my wife Shannon’s Birthday. Not only is this important to our family, but it means we will be out in the building humidity with more possible storms. I may post an update or two, but my day is dedicated to spending time with her.

It is also really unique in the climate records… Which I highlighted below. 

Recapping The Rain

Saturday brought big rains to parts of our area, with the hardest hit in central Anne Arundel Couty.  Doppler radar has ‘estimated’ the amount of rain. It has been suggested that this is lower that what some have recorded, but does illustrate where the heavy led to flash flooding.

Anne Arundel County

This was due to a stalled boundary leading to repeating slow moving cells in the late afternoon and evening.

Between 3 and 5 Inches of rain fell around Crofton, Bowie, and Edgewater (top mark).

Annapolis had around 1 inch of rain as depicted here.

Mount Airy-Westminster

Storms in this area hit earlier in the day and erupted with plenty of lightning.

3 Inches Of Rain fell on the north side of Mount Airy.

This Morning

Satellite Loop 5:30 AM to 7:30 AM

More clouds and impulses to our west will be on the move. Expect more clouds to build and spark scattered storms today.

Afternoon Temperatures 

Radar Simulations

We are in the season with pop up storms that models can’t handle well. I mentioned this yesterday and we saw it play out.  Please take these maps as suggestions, but plan for more activity likely.

The track will be to the east..

NAM 3Km 4 PM to Midnight 

This model is later with the storm cluster for metro areas – tonight. 

As we have seen many times, this produce may be slow… meaning we could expect development and arrival earlier than suggested here.

It still looks like the better chance for showers and storms will be later in the day.
