The National Weather Service has issued a severe thunderstorm watch for the entire region that will be in effect until 9 p.m. Friday.

According to the alert, isolated hail up to the size of a ping-pong ball is possible, as are scattered wind gusts up to 70 mph. In addition, frequent lighting is possible.

The watch extends from Virginia all the way up the East Coast to Connecticut.

Locally, the Washington Post’s Capital Weather Gang says they “expect that there will be a few severe thunderstorm warnings,” and to “anticipate scattered power outages from downed limbs.”

A heat advisory from the National Weather Service will be in effect from 11 a.m. to 8 p.m. Friday, as temperatures soar into the 90s.

From the alert:

…HEAT ADVISORY IN EFFECT FROM 11 AM THIS MORNING TO 8 PM EDT
THIS EVENING…

The National Weather Service in Baltimore MD/Washington has
issued a Heat Advisory, which is in effect from 11 AM this
morning to 8 PM EDT this evening.

* HEAT INDEX VALUES…Around 105 degrees due to temperatures in
the lower 90s and dewpoints in the mid to upper 70s.

* IMPACTS…The heat and humidity may cause heat stress during
outdoor exertion or extended exposure.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Heat Advisory means that a period of high temperatures is
expected. The combination of high temperatures and high humidity
will create a situation in which heat illnesses are possible.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency — call 911.

The National Weather Service says strong thunderstorms are possible this afternoon as well, with frequent lightning, damaging winds and large hail possible.

Drivers are asked to exercise caution this morning as the National Weather Service has issued a dense fog advisory that will be in effect until 9 a.m.

According to the NWS advisory:

…DENSE FOG ADVISORY IN EFFECT UNTIL 9 AM EDT WEDNESDAY…

The National Weather Service in Baltimore MD/Washington has
issued a Dense Fog Advisory, which is in effect until 9 AM EDT
Wednesday.

* VISIBILITIES…One quarter mile or less at times.

* IMPACTS…Areas of dense fog will cause sudden reductions in
visibility and rapidly changing conditions, making travel
difficult.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Dense Fog Advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving, slow down, use
your headlights, and leave plenty of distance ahead of you.

Fairfax County Fire and Rescue has shared a number of fog safety tips for drivers who will be out in the hazardous conditions this morning.

  • Slow down and allow extra time to reach your destination.
  • Make your vehicle visible to others both ahead of you and behind you by using your low-beam headlights since this means your taillights will also be on. Use fog lights if you have them.
  • Never use your high-beam lights. Using high beam lights causes glare, making it more difficult for you to see what’s ahead of you on the road.
  • Leave plenty of distance between you and the vehicle in front of you to account for sudden stops or changes in the traffic pattern.
  • To ensure you are staying in the proper lane, follow the lines on the road with your eyes.
  • In extremely dense fog where visibility is near zero, the best course of action is to first turn on your hazard lights, then simply pull into a safe location such as a parking lot of a local business and stop.

Heavy rains are being predicted for the entire region the next two days, and emergency agencies are warning that may mean flash flooding.

A flash-flood watch has been issued for the area, to be in effect Friday afternoon through Saturday afternoon. According to the National Weather Service, a stationary low pressure cell may bring torrential rains.

Low pressure is going to develop over the Mid-Atlantic Friday and remain nearly stationary this weekend. This will have the potential to bring 3 inches or more of rain to the region through Saturday afternoon. Thunderstorms could cause locally higher rainfall amounts.

Heavy rainfall may result in rapid rises in streams and creeks. This could quickly result in flooding… especially in low lying and poor drainage areas.

Precautionary/preparedness actions… a flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.

The Washington Post’s Capital Weather Gang says this storm’s structure is similar to that of a winter storm. They say some pockets within the storm may see upward of 7 inches of rain.

“Heavy storms may line up along a corridor and hit the same areas repeatedly — a worrisome phenomenon known as training,” the CWG says. “Areas that experience training will be most prone to flooding.”

Fairfax County offers some of the following tips of how to stay safe if flash flooding occurs or has the potential to occur:

  • Move immediately to higher ground. Do not wait for instructions to move.
  • Always stay away from floodwaters.
  • If you must walk in water, walk where water is not moving; use a stick to check the ground.
  • Be aware of streams, drainage channels and other areas known to flood suddenly. Flash floods can occur in these areas with or without such typical warnings as rain clouds or heavy rain.
  • Keep your children inside and away from streams and creeks.
  • Stay away from downed power lines to avoid the risk of electric shock or electrocution.
  • Keep your vehicle parked in your garage or on the driveway away from low-lying areas and large drains.

Residents are also reminded not to drive on flooded roads:

  • Stop and take an alternate route. The depth, current and condition of the road are all unknowns and can be deadly.
  • If your vehicle stalls on a flooded road and water is rising, get out of the car, call 9-1-1 and move to higher ground.
  • Be especially cautious during periods of limited visibility or nighttime when it is extremely difficult to see and judge conditions — state law requires headlights when wipers are on.

Fairfax County offers these pieces of advice for people to help avoid heat-related illness and other calamities:

  • Never leave children or pets alone in a closed vehicle.
  • Take extra precautions if you work or spend time outside.
  • When possible, reschedule strenuous activities to early morning or evening.
  • Wear lightweight and loose-fitting clothing when possible and drink plenty of water.
  • Drink plenty of fluids: Drink two to four glasses of cool fluids each hour. Your body needs water to keep cool. Drink water even if you don’t feel thirsty. Do not drink caffeinated or alcoholic beverages because they dehydrate the body.

The county suggests that residents without access to air conditioning should consider spending the warmest part of the day in public buildings such as movie theaters, shopping malls and other community facilities, or visit one of Fairfax County’s Cooling Centers.

If you ever had that fantasy of cracking an egg on the sidewalk and watching it sizzle to perfection, this week may be your chance to make that a reality.

Today, the National Weather Service issued a hazardous weather outlook for Fairfax County and other Northern Virginia areas. This outlook applies to the coming days as well. In the next few days, the mercury will be way up on the thermometer — even nearing the triple-digit zone.

While your instinct may be to throw some “floaties” in the pool and stock up on bottles of rosé for the fridge, you may want to keep an eye out for symptoms of heat stroke or heat exhaustion.

According to the National Weather Service, symptoms of heat exhaustion include feeling faint or dizzy, sweating excessively, cool, pale or clammy skin, nausea or vomiting, a rapid, weak pulse, and muscle cramps. It is recommended that anyone experiencing those symptoms should go indoors to a cool place, drink water, and take cool showers or use cold compresses.

Signs of heat stroke include throbbing headaches; the absence of sweating; a body temperature above 103 degrees; red, hot, dry skin; nausea or vomiting; a rapid, strong pulse; and the potential to lose consciousness. Should a person encounter this scenario, they must call 911 immediately.

For those who do not have air conditioning in their house, Fairfax County recommends going to the movies, visiting shopping centers or going to one of the county’s designated cooling centers — including Reston Regional Library and the Southgate Community Center.

The county also recommends that citizens:

  • Drink plenty of fluids even if you do not feel thirsty.
  • Take several breaks from the heat, especially midday when the sun is hottest.
  • Wear loose, lightweight, light-colored clothing, and sunscreen. Remember that you should reapply sunscreen every three to four hours.
  • Take cool showers or baths to cool down.
  • Check on friends or neighbors during extremely hot days and have someone do the same for you.
  • Never leave children or pets in cars.

Cornerstones, a nonprofit organization in Reston, offers short-term emergency financial assistance to people who need help with their cooling bills.

So, keep cool and carry on.

You’ve undoubtedly noticed, it’s a wet and rainy morning around Reston. Will the rain let up today?

According to the National Weather Service, there’s a chance, but not a big one.

Rain and the chance of thunderstorms is likely until at least 2 p.m. Friday, with the added likelihood of “gusty winds.” Temperatures will mostly remain in the 60s, with a possible high of 73 degrees.

Around mid-afternoon, there is a chance the rain will finally stop between 2 to 4 p.m. Then, the chance of showers tonight goes down to around a 30-percent likelihood. Temperatures tonight will hover in the 50s.

For the weekend, sporadic rain is highly likely. The chance of rain is 70 percent between 11 a.m. to 2 p.m. on Saturday, with a mostly clear mid-day leading to a 30-percent chance of rain returning around 8 p.m. Temperatures will linger in the 50s with a high near 64.

Thankfully, it looks like Restonians may be able to enjoy a dry Sunday. There is only a 20-percent chance of showers around 8 a.m. However dry, though, it will likely be an overcast and windy day, with temperatures in the 50s and wind gusts of up to 24 miles per hour.

Summer isn’t here to stay just yet, say the folks at Capital Weather Gang.

There’s a 40 to 60-percent chance of thunderstorms today, starting around 6 p.m.–and we’d agree that the chance is likely given the gray clouds hanging over the Reston area right now, and how the winds started picking up around lunchtime.

Though Reston saw temps in the high 80s to lower 90s this past weekend, with abundant sunshine, the forecast is trending cooler through the rest of the week and even into the weekend, making it feel more like March, say the Gang.

Tuesday and Wednesday are looking to be the week’s  sole bright spots, with temps approaching the low 80s. Winds are likely to be rather gusty though, hitting 25mph at some points throughout the day Tuesday.

Expect it to be significantly chillier Tuesday night, when the lows will barely be in the 50s, but the sun is expected to return Wednesday morning, amid clear skies and temperatures in the breezy 70s for the rest of the day. Lows in the 50s will return Wednesday night, the Gang predicts.
