FORECAST IN DETAIL

As hot as it's been over the last several weeks, it's hard to believe that today is just the first official day of summer. And if the week ahead is any indication, it's going to be a loooong summer. Every day (this week), chances are good we reach 90 or higher, with 95+ possible midweek. Hit-or-miss late day storms, entering the picture starting tomorrow, offer little relief, as the heat just keeps reloading after any temporary breaks.

Today (Monday): Kind of like yesterday, it's going to be hot but moderate humidity levels keep it tolerable. It's probably even a few degrees cooler than yesterday (which hit 95) with prevailing winds from the north instead of the west. Most spots experience highs in the low 90s under mostly sunny skies. Confidence: High

Tonight: With clear skies and humidity levels remaining moderate, it's actually a pretty comfortable evening. Lows fall into the 60s in most of the suburbs but closer to 70 downtown. Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Tuesday): As winds come around to out of the south, it starts getting sticky. Under partly sunny skies, highs head up into the low 90s but feel like the mid-to-upper 90s. With the added moisture around, a few thunderstorms could begin popping late in the afternoon (20% chance), especially west. Confidence: Medium-High

Tomorrow Night: Evening thunderstorms are possible (20-30% chance) followed by partly cloudy skies and mugginess. Lows are only around 70 in the suburbs with mid-70s downtown. Confidence: Medium-High

A LOOK AHEAD

The heat and humidity border on the oppressive Wednesday and Thursday. Highs probably reach the mid-90s both days but feel more like 100. These highs will depend on the amount of cloud cover which will be variable. If we get more sun, upper 90s are possible; less sun and we may just see the low 90s. Scattered showers and storms are possible both days (30-40%), a few of which could be strong. The overnight periods see fading storm chances with lows mostly in the 70s. Confidence: Medium

The oppressive heat and humidity (and thunderstorm chances) may take a breather on Friday behind a weak cold front, but it's still probably hotter than average. Highs head up to around 90. Mostly clear at night with lows in the mid-60s to near 70 (suburbs to city). Confidence: Medium

It's shaping up to be another hot weekend. Highs both days should be in the low-to-mid 90s with increasing humidity. The best chance of thunderstorms looks to be Sunday but activity should be scattered. Confidence: Medium

gee, where are all of those commenters who were endlessly griping about the cold back in February...lol.....happy now? I know, you are all to busy outside dancing in the streets to comment how wonderful it is to finally be able to spend so much time outside, and not worrying about your high heating bills, right? You guys are more than welcome to come over and water my lawn, you supply the water of course...lol.

I am griping about how little rain we have squeezed out of Spring 2010. Now we are heading to the hot dry summer period behind the curve. I am praying for a tropical storm to come up the coast and deluge us.

Thanks guys for the regular humidity forecasts along with the temps - as I always tell newcomers to the region, it's not the temps that get you, it's the dewpoints...

ftwash, if you had saved your snow in an extra large pile you could use it to water your lawn right now!

ftwash - I love it! I freaking hate summer...I have a burned lawn, you can't breathe outside, and you sweat from going to get your paper on the driveway every morning.

In my book, February is better than anything offered from June through August.

Happy Solstice everyone. Stay cool.

I second the Happy Solstice! Remember, all, we live in a place that has close to four seasons. It is summer -- and last night was a lovely night after the sun went down, not much humidity. (My perspective is Houston). Finally, I will say again, please don't pray for tropical deluges or other deluges ....Floods are not good things.

Several models keying in on tropical development now with new invest in the Caribbean. The Euro, which is generally a great model, has a pretty big hurricane hitting the northern Gulf about a week out.

ftwash: I love summer! and yes, i havent been posting all day here because i'm too busy getting out and enjoying the long, beautiful days. as hot as it gets, it still beats February when it gets dark at 4.30 and everybody's hunkered down and ticked off. I'm meeting neighbors I never knew I had. and grilling delicious LOCAL vegetables. and attending all the local festivals that DON'T occur in Feb for a reason. Ok, that's it.

so hot today - feels like august!

...And I'm griping about the folks like rocotton above, who seem to DELIGHT in dumping downpours on me at inappropriate times such as 8:10 tomorrow evening when I need to get to the Clarendon Ballroom for the weekly Tuesday night swing dance...we have rain threats on 50% of the extended outlook, including tomorrow evening...let's hope we can get that 30% chance of thunderstorms out of the Clarendon Ballroom outlook tomorrow. Hardly a dry summer forecast.

@Ian 10:36 am -- "big hurricane" -- big as in size, or big as in strong?

Posted by: Murre | June 21, 2010 2:57 PM | Report abuse

Big as in strong. But alas, it is much weaker and further west on the new run.. models have trouble when there is no real circulation for them to base their forecast off of. It does appear there will be something to watch though.

Posted by: Ian-CapitalWeatherGang | June 21, 2010 3:03 PM | Report abuse

Thanks, Ian, weaker and to the west is better for the northern Gulf.
