Update: Lower storm threat tonight, repeat of Friday night unlikely; still hot Sunday

Thankfully, somewhat cooler and drier air trickled into the region behind Friday night’s violent storms. Although it’s still quite hot (mid-90s), the atmosphere is not as unstable as last night. Some thunderstorms may still develop (40 percent chance), but they should not be as intense or widespread as last night.

Derecho: Behind Washington, D.C.’s destructive thunderstorm outbreak, June 29, 2012

Between 9:30 and 11 p.m. Friday night, one of the most destructive complexes of thunderstorms in memory swept through the entire D.C. area. Packing wind gusts of 60-80 mph, the storm produced extensive damage, downing hundreds of trees, and leaving more than 1 million area-residents without power.

D.C. area forecast: Dangerous heat, power outages and more storms

With more than 1.5 million Maryland and Virginia homes and businesses losing power in last night’s severe weather, the one thing we don’t want is another super hot day filled with a significant storm threat. Unfortunately, we’ve got it. This heat is bad enough on its own, but given the sizeable outages and likely lengthy period to restore, extra caution must be taken by those “in the dark.”

Vulnerable to extreme temperatures: CWG helped one charity help the homeless

During a hot time of year, it is important to remember that homeless members of our population are just as vulnerable as in cold times of the year. Please remember to call 1-800-535-7252 if you see someone in distress during the upcoming heat wave.

Colorado wildfires: is lack of spring snow the smoking gun behind the blazes?

When we discussed the role of weather yesterday in Colorado’s wildfires, we mentioned the historic, sweltering temperatures, the state-wide drought, low humidity, and gusty winds. But we neglected perhaps the key environmental contributor: the profound lack of spring snowpack across the state.

Tomorrow’s temperatures are still mainly bearable, even if turning hot. But by Friday -- when excessive heat watches are already up -- you’ll probably feel like limiting your time outdoors.

Summer sizzle is on its way back. But at least it’s nice enough to allow us a gradual transition. The warm-up starts today, but we probably don’t break 90 until tomorrow, and the humidity shows some restraint until Friday. Starting Friday, though, the heat and humidity team up for a one-two punch straight through the weekend. Any chance of a cooling thunderstorm?...

Today’s weather was tough to beat. Sure it was breezy at times, but the abundance of sunshine and absence of humidity made it a pleasure to be outdoors. A lovely night lies ahead - it’s almost fall-like with crisp morning temps. Wednesday’s not at all bad considering the low humidity but, by afternoon, temperatures turn a bit toasty.

The atmosphere had all the fuel it needed to trigger some severe thunderstorms. It did that, and damaging winds, torrential rain, and hail raked a narrow area that spanned from Bethesda, Md. through northern Washington, D.C into Landover, Md.

Temperatures are still going to be rather warm, but humidity is down compared to recently and that alone should make for a noticeable difference. Now that we’re in summer by all measures, it could be much worse! Plus, there’s a cool-down in the not-to-distant future.

Highs that have made it into the mid-and-upper 90s (likely just shy of a record 99 at National) are of course well above normal for the date, if not particularly unheard of for this area. If you aren’t a fan of it, you might want to lock yourself in an air conditioned building at least through tomorrow. Unfortunately, we’ve got more heat advisories and potentially unhealthy conditions to deal with.

Department of Labor urges heat safety for outdoor workers; heat advisory thru Thurs.

The heat advisory for the Washington D.C. and Baltimore regions has been extended to cover the overnight hours tonight and Thursday through 10 p.m. On Thursday, another scorcher is expected, with afternoon temperatures in the upper 90s to near 100 and heat indicates around 105. Hot day time temperatures represent a particular hazard for outdoor workers. In response, the Department of Labor has launched a campaign to confront the risks posed by extreme heat.

Washington, D.C.: hottest spot in the East

Once again, Washington, D.C. finds itself at the epi-center of a heat blast torching the eastern U.S. At noon, D.C.’s 93 degrees was at least 5 degrees warmer than southern cities like Miami, Atlanta, Raleigh, New Orleans and Houston.

An alternative “temperature-based” definition of summer and the seasons

For most of the mainland United States the meteorological seasons, agree more with temperatures than the astronomical seasons. But I came up with a more precise way to define seasons based on temperatures.

Summer solstice 2012: Longest day of year - how does daylight compare around the world?

If you’ve enjoyed these bright, sun-filled evenings for an outdoor barbecue or a neighborhood stroll, the summer solstice tonight marks the culmination of our long-lasting daylight. At 7:09 p.m. (EDT) today, the sun will shine directly overhead at the Tropic of Cancer while the North Pole reaches its maximum tilt towards the sun. For the northern hemisphere, this marks the official start of summer and the longest day of the year.

D.C. area forecast: Two days of extreme heat with heat index near 100-105

After yesterday’s half-court attack, summer puts on a full-court press today and tomorrow with an intense dose of record-challenging heat and rather high humidity, too. If you have to be outside during the afternoons, make sure it’s not for an extended period of time unless you’re in the water or in the shade. The heat steps back to more typical summer levels Friday through the weekend with a few thunderstorms possible along the way.

As we move forward through the end of June, much of the Northeast will get a couple more shots at the 90s during an otherwise average to cooler-than-average regime, while places in the mid-continent will continue to roast, and perhaps accumulate 100-degree days much earlier than usual.

After yesterday’s radically cool result (Dulles stayed below 70), we are sitting in the way of a high powered heat train, delivering the hottest weather of the year so far. The heat hits its peak on Thursday with upper 90s and some scattered 100s possible. Moderate-to-high humidity means the heat index exceeds 100. A cool front by Friday starts to derail the heat.

Persistent clouds and showers that largely tapered off after the morning have kept us quite cool this afternoon.

An approaching cold front is working to tap vast moisture in the Southern U.S., sending some heavier downpours our way into this evening. While we need rain, the occasionally inclement conditions hinder transportation and other outdoor activities. After that, high pressure builds to our north and sits there through at least Sunday. This “Tortoise” high keeps temperatures near normal and conditions mostly dry.

Dew points are a bit higher today, but they’re still low enough to make highs in the low-to-mid 90s a tolerable heat.

I wish I could say the weekend will be exactly the same, but we’re staring down a run at 90-degree readings and increasing humidity levels. Still, it’s June, and it could be worse.

Water diet for the garden, watching your waste

We know too well that warmer days are ahead and rains will be erratic. Methinks it’s a good time to look at some ways to maximize the moisture we get during the course of the summer.

Is that a tornado? Wall, scud, shelf and other scary looking clouds

During last Friday’s thunderstorm outbreak, a number of images were passed around as tornadoes that were clearly not tornadoes. Let’s examine a few of the most common scary looking clouds that sometimes are mistakenly called tornadoes.

Forecast: Pleasant end to workweek as warmth builds

Ready to start sweating again? After today’s increased warmth, we crank up the heat back to summer levels again. We also won’t have a chance at truly more organized rain/thunder/showers again until Tuesday, but a lucky few of you over the coming days still may squelch your 90+ degree readings with one. Get to the pool or shore, and lather on that sunscreen please!

Today marks the return to normal temperatures...for exactly one day. Yes, summer lovers, here you go. I would not be surprised to see some stray 90 degree readings by Saturday and a whole bunch of them by Sunday. The saving grace is humidity levels will be very slow to increase.

PM Update: More pleasant times to come, along with a slight rain risk

Our cooler than average start to June brought us another pretty fantastic one today. Highs reaching into the low and mid 70s, off lows in the 50s, are really quite a treat. We’ve still got some of that cold air aloft helping to create clouds as well, but they’ve generally been fewer than yesterday. The outside risk of a quick shower or t’shower prior to sunset remains low enough to not cause any widespread worries.

Is a high false alarm rate for tornadoes cause for alarm?

Published research tell us for every four tornado warnings issued in the U.S., only about one actual tornado touches down. During Friday’s severe weather outbreak in the Washington/Baltimore region, there were more than a few false alarms, prompting questions about whether the barrage of storms was overwarned and overhyped and, if so, what to do about it.

June is off to a cool start in Washington, D.C. and much of the Northeast this year. As forecast last week, a big dip in the jet stream has released cold air out of Canada. Today will be Washington, D.C.’s third consecutive day with highs only in the spring-like 70s.

Transit of Venus 2012: Celestial spectacle, clouds notwithstanding (PHOTOS)

In many parts of the United States, clouds interfered with the historic transit of Venus. But for some patient skywatchers, there were enough gaps to capture this rare event. That’s a good thing, because the next transit won’t occur for 105 years.

PM Update: Clouds to mostly obscure transit of Venus, remaining cool

Our snap of cool June weather reached its maximum intensity today as temperatures struggled to reach 70 degrees. It was the coolest June day since June 5, 2009 when the high was 63. Mostly cloudy skies had a lot to do with the cool temps and they will also compromise viewing prospects for the transit of Venus beginning at 6:04 p.m. EDT. More cool, cloudy weather is on tap for Wednesday along with the chance of showers.

Forecast: Cool pattern continues; 80s and more sun featured this weekend

A large dominating dip in the jet stream (known as a “trough”) is keeping us quite cool with just enough upper level instability to trigger shower risks, especially in the afternoons. This feature starts to ease out of our area just in time for Friday and the weekend, which should allow us to pop back into the 80s and feel a bit more like summer (and it looks mostly dry too!).

Forecast: Spring-like 70s, PM shower chances through Thursday

A big dip in the jet stream over the East assures a cooler than normal start to the work week. In addition, little waves in the atmosphere cycling through the region may ignite some afternoon and evening showers and thundershowers through Thursday. It’s more of an April-like pattern, but headed into the weekend, we dry out and more of a June-like pattern settles in.

The upper-level low lingers through the first half of the week, keeping us in a pattern of variably cloudy skies with afternoon shower chances.

Stay alert today for potentially a few batches of storms, possibly severe this evening and overnight. Some of the storms late today look like they’ll be severe, and that can include damaging winds, large hail, and perhaps even tornadoes. Once we get this cold front through the region, we have a serene Saturday and salvageable Sunday. Next week stays fairly seasonable in the mid-70s to low 80s, though perhaps not completely dry.
