It bubbles up over point A, pours itself out, and never moves on. What we’ve been in in the last few weeks is incredibly high levels of humidity, and like Florida in the summer, there’s nothing to push the storm from point A to point B. “What causes that is how much moisture the atmosphere contains. The last two to three weeks, we’ve essentially had Florida weather, when it’s raining on one side of the street like crazy but not raining on other. We’ve had a lot of those incredibly high-impact but small-scale events. “A week ago Sunday, it literally rained at my house in the Logan/Shaw neighborhood, but it never rained at National Airport or in Bethesda. “In the last two weeks, we’ve had some unusual events,” Bell says. We all may simply be noticing the weather more, because so much of our new normal depends on planning socially distant outdoor gatherings or eating at a sidewalk restaurant table.Īs for getting caught this week in a freak storm that seems to come out of nowhere? You can’t blame Covid-19 for that. But that’s still an incredibly accurate forecast.”īell does insist that despite the decrease in data, he has not noticed any drop-off in NBC4’s forecast accuracy. By way of example, if a forecast may have been inaccurate once a month before, Bell says, and now, as a result of the decreased data, the forecast could be off twice a month, “now you’re missing it twice as often. “We can be right 99 times out of 100, but the one time you go out and walk your dog and get rained on, that one time is the one time you remember,” he says. When you give up that kind of density, it has to have an impact.”īell says that because modern satellites have made forecasting so much more accurate than it was in the past, viewers seem to notice more when a forecast is wrong. Every modern jet is essentially a flying weather station, constantly sending back data-here is the altitude I’m at, and here is the temperature, the humidity. In fact, 85% of the observations that feed our global weather forecast model comes from polar-orbiting satellites.”Ĭhuck Bell, a meteorologist with WRC-TV, does say, “I think there has been a slight degradation. Automated weather reports from commercial aircraft provide exceptionally valuable data for forecast models, but we also collect billions of Earth observations from other sources that feed into our models, such as weather balloons, our surface weather observation network, radar, satellites and buoys. We have not seen any noticeable reduction in model accuracy. Look for the WBAY First Alert Weather App in the Apple app store and Google Play ( click here on your mobile device).A statement from the National Oceanic and Atmospheric Administration sent to Washingtonian said they have not, in fact, seen any deterioration in forecasts: “Despite the reduction of commercial passenger flights, we still receive valuable aircraft data from the passenger flights that are ongoing and from flights by cargo carriers.

With that said there is the potential for some flooding as well, so KEEP INFORMED! It is quite dry in most areas, so hopefully most rain will soak in. 1-3 inch totals are looking likely, and some areas could see locally higher amounts. As long as the front is nearby, rounds of showers and storms will continue Sunday and Sunday night.Īny storms tonight all the way into Sunday night could put down some very heavy rainfall and pack gusty winds. This front will move VERY slowly (and even stall at times) across the region, not fully exiting until early Monday. There is a SMALL CHANCE of storms by this evening, but the best chances for showers and storms will arrive tonight as a cold front approaches the area. Heat index’s as a result of the high heat and humidity will top out in the middle to upper 90s! After some sun in the morning, more clouds will start to arrive. Very sticky 70 degree dew points will be in place Saturday along with plenty of heat, with most areas warming into the upper 80s to low 90s. It’s a quiet start to the morning, but we’re starting off steamy already.
