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.

Snow plows/VDOT

After a snowless winter, it looks like Reston will finally be hit.

Forecasters are predicting several inches of snow for the area, with an outside chance of a foot or more, beginning tonight and continuing into Tuesday.

The National Weather Service has placed an area including Reston under a winter storm warning that is scheduled to begin at 7 p.m. Monday and last through 2 p.m. Tuesday. According to the alert, their official predictions include the following:

* PRECIPITATION TYPE…Snow…possibly mixed with sleet at times
Monday night.

* ACCUMULATIONS…Snow accumulation of 6 to 10 inches.

* TIMING…Snow will overspread the area Monday evening and
persist through Tuesday morning.

* IMPACTS…The heavy snow will create difficult travel
conditions and may produce scattered power outages.

* WINDS…Northeast 5 to 15 mph with gusts up to 30 mph.

* TEMPERATURES…In the lower 30s.

In preparation for the storm, the Virginia Department of Transportation began pre-treating roads Sunday. The department is encouraging drivers to adjust their schedules to be off roads before the evening rush hour Monday and overnight.

“This will help avoid being stuck on the roads when the storm begins, and to allow crews room to work more safely and efficiently,” VDOT said in a release.

In addition, VDOT asks that vehicles be parked in driveways, or that communities coordinate to all park on the same side of the road, to allow a larger path when plows begin to focus on neighborhood streets.

Such a significant snowfall would also have an impact on public transportation.

Metro will suspend its MetroAccess paratransit services at 4 p.m. today, and they will remain out of service through Tuesday. In addition, Metrobus service changes are possible and will be announced based on weather conditions and forecast.

Fairfax Connector is reminding users that service may be reduced, modified or suspended, on a route-by-route basis or systemwide. Riders are encouraged to monitor schedules online or call customer service (703-339-7200) for updates.

Heat index for July 14, 2106/Credit: NWS

Fairfax County is under a heat advisory for Thursday, July 14, which is expected to be the hottest day of the summer so far.

The National Weather Service (NWS)’s heat advisory will be in effect from from noon to 8 p.m. A heat advisory means that a period of high temperatures is expected.

Temperatures in the middle 90s combined with high humidity values will produce heat index values between 100 and 105 degrees. This combination of high temperatures and high humidity will create a situation in which heat illnesses are possible, says the Fairfax County Office of Emergency Information.

To reduce risk during outdoor work, the Occupational Safety and Health Administration (OSHA) recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.

You also may visit any of the county’s Cooling Centers, held at county facilities such as senior centers, RECenters, community centers and libraries, for temporary respite from the heat.
