Forecast: Sweltering Heat Continues

A few strong storms could pop this afternoon/evening

*Heat Advisory in effect until 11 p.m. Monday*

By Brian Jackson

The worst alliteration in a meteorologist's arsenal will be with us for the next few days: hazy, hot and humid. Temperatures will be approaching 100 degrees and humidity levels will be high. Sunny skies may feel overbearing for those of you outside for an extended period today and tomorrow, so drink plenty of water. By midweek, we'll experience some minor relief after a cold front passes through the area late Tuesday.

TODAY (SUNDAY)

Oppressive heat and humidity. Late day t'storm? 95-100. The heat is on again today. A hot sun will once again raise the mercury to near the century mark. Dew points near 70 will raise the heat index to 100-105. Winds won't be providing much relief, blowing from the west-southwest at under 10 mph. With such high surface heat and moisture creating loads of instability, we could see a few late afternoon and evening thunderstorms with heavy rain, dangerous lightning and strong winds.

Overnight, it stays muggy. Lows will only drop into the mid 70s under mostly clear skies. Some of our urban areas may only cool to the 80-degree mark. It will be very sticky out and this could create some areas of fog toward morning. Winds will blow lightly from the west.

Confidence: High

Keep reading for the forecast into early next week. See NatCast for the blazing hot outlook for today's game.

TOMORROW (MONDAY)

Hot again. 95-100. We'll get no reprieve from the hot weather to start the work week. Watch out for some areas of fog on your morning commute, but that will quickly burn off as the sun rises. Once again we'll approach triple digits with plenty of sun and an afternoon high in the mid to upper 90s. I'll mention the threat of thunderstorms, but they should be mostly confined to the higher terrain to the west.

Monday night will be another humid one. Clear skies again will cool us to the dew point, the mid 70s, and as a result we could again see areas of thick fog develop, especially if light winds from the west (at around 5 mph) eventually go calm.

A LOOK AHEAD

On Tuesday we'll stay hot, but not quite as oppressively as Sunday and Monday. A cold front begins to approach from the west raising our chances for afternoon thundershowers to around 30%. Even in areas that don't see the rain, we should see some cumulus develop, holding temperatures to only the lower 90s. Confidence: Medium-High

Wednesday, we'll have another shot to crack the 90-degree mark but most should only see the upper 80s. Skies will be mostly sunny in the a.m. hours, but by afternoon clouds should build and we'll again see the chance (40%) for afternoon thunderstorms. Confidence: Medium-High

Last night's thunderstorms resulted in an inch of rain in a short time. So far this month, we've received about 4.3 inches. Like May, June is turing out to be a wet month.

What are the chances that next weekend will be more bearable? The Alexandria Waterfront Festival takes place then, and it would be great if the volunteers didn't have to roast.

When you guys switched over to the Post you mentioned that you were working on something where people could post their own photos like before. What happened to that?

No fog, but it looks like some clouds are moving in.

I predict a 50% chance that DCPS closes school Monday for excessive heat. Plenty of schools have no A/C, and DCPS didn't have a snow day, 2 hour delay, or early dismissal all year. Who's with me?

Oopsie, one of you guys forgot to close off one of the "bold" HTML tags. :P

I love the picture that Ian took!

It's 87° already at 10:57 AM. That's sickening. Oh well, nothin' you can do about it.

We have the A/C on and the Fla-Vor-Ice pops are frozen solid in the freezer, so I'm ready. I wouldn't mind another storm today though. The lightning and thunder last night was amazing.

Glad to have power back on here in Sterling. It went out at around 3 in the afternoon yesterday, and came back on at around six. Then, storms moved through, and the power went out again at 8, and came back on at 2 in the morning. Quite a night... I was very nervous about my refrigerator. Everything survived, though. :-)

What a lightning show last night! I spent much time sitting on the porch watching it. Lots of sheet lightning, and flashed from the clouds. Funny, though, no thunder. I guess it was very far to the east?

Anyway, pending power, I'll be checking CWG today in case of a repeat performance.

While out running errands (no choice, no food in the house), I realized how darn hot it really is. This got me wondering, does DC and the surrounding areas have a plan in place for checking on the elderly during heat waves? I remember several years ago hundreds died in Chicago during a heat wave. They couldn't afford to turn on the a/c, so they died from the heat.

If you have an elderly neighbor, or anyone you think might be having trouble in this heat, please check on them.

I don't think DC has a plan for checking out the elderly during heat waves. It's similiar to their failed plan at curbing the tide of killings in the city and accepting a former "druggie" mayor to run for City Council over and over again.

@JT
The post has recently implemented a site wide feature where users can upload their own photos, and we are working with the post to bring this sort of functionality locally to the blog. This will allow us to provide upload, storage, and slideshow capabilities right from the blog.

Doesn't anyone find it alarming that weather systems are collapsing all over the globe? You still think global warming isn't real? It's an extinction level event. Write your representative to have Project Medea declassified. Cheney was SECDEF when he buried it, gee I wonder why? Cuz he's in the pocket of big energy? Look on the bright side. There won't be an obsesity problem when we're starving to death. I understand human flesh is actually quite tasty.
