PM Update: Heat and humidity clobber region

Posted this a few minutes ago in morning update but will ask question re: it here.

Now that it appears that the front passing thru on Friday is gonna hang up just to our south, keeping us in clouds, showers and an easterly wind into Saturday, when will we see an improvement in the weather?

Could this linger into Sunday too?

Ian,

Looking at the latest GFS and NAM runs, it appears that the stormy weather may hold off until after sunset tomorrow evening. Is this a fair assessment or is there something else that leads one to believe that the storms up north will make it into our area before the sun sets? Gotta cut two lawns before they are too wet or else wait until Sunday when they dry out and are too long. UGH!

any idea on timing of tomorrow night's t-storms? are we talking early or late evening? thanks in advance!

In terms of overall morning mugginess here, what's the worst that it can get? Temp + dewpoint (or humidity) please. I usually walk to my metro station about 7:30 am and need to either 1) take the bus or 2) run to it in my shorts and take a shower at work. Thanks.

pjdunn1, I would tend to lean toward later evening or into the early overnight... maybe 6-11 (or centered somewhere around sunset)? But something could sneak in before that. I'm still not totally sold we'll get a lot of action but given the instability etc whatever does make it in could be fairly strong.

As usual, thanks a bunch Ian! Always can count on you and the gang.

jojo2008, Once you get into the upper 60s or around 70 for a dew point I don't think there are many who would argue it's not that humid... so you're nearing as muggy as it typically gets. I think we'll end up staying a bit below the "oppresive" level (which in my head is about 70+ for dews) but not far. That said, those types of readings are fairly common during the summer here. It's more rare once you get into the 75-80 range for dew points. So, tomorrow morning should not be too much different than your normal summer morning.

Highs: DCA, 90.. IAD, 87.. BWI, 91. Southern New England was roasting. Bradley airport near Hartford hit 99.. highest May temp (tied) on record.

Ian,
Thanks. Yesterday morning wasn't that bad in terms of walking. Lunchtime was. I walked to Union Sta. and my back was drenched. Just wanted to know what to look for.

Two items in off the weather board...

1) There's talk of "very large hail" with tomorrow's severe weather...1" to 2" was mentioned. Largest hail I've seen here was golf-ball size, on two occasions, both in August.

2) Discussion of a severe heat wave in Pakistan...one site had 53.5 Celsius, [128+ Fahrenheit], fifth hottest temperature recorded worldwide. For everyone's information, the site is Mohenjo-Daro, one of the major historic sites of ruins from the mysterious, and still little-known Indus Valley civilization...we may surmise that a prime reason for the complete disappearance of the Indus Valley civilization involved intense heat waves and drought, perhaps climate change, Mr. Q.
