Hot and Humid conditions. Very nice tomorrow. Rain chances Friday and Saturday with nice Sunday and Memorial Day!
Mostly cloudy today and warmer. Tomorrow will be hot and have a chance of strong to severe storms. The weekend starts wet but turns beautiful.. however, the temps will be very cold!
Apologize for my absence. Finally a break in the Heat with a front that is pushing through today. It only is bringing a little rain along with it. Maybe it will help wash a bit of pollen out of the air, but, unfortunately the outcome is less than ideal for the very dry conditions we are experiencing.

The dome of high pressure that WTOP.com (and CNN) are sharing is not uncommon, but the location has been less than ideal as it has kept us dry and our first heat for the summer 2021 season. I hate the heat, but fortunately, the winds and drier air made it a bit more tolerable. The heat did wake up the dormant Cicadas that had been slow to get their act together! But, officially, they are here! They sound like aliens in the trees. I have not seen too many in my backyard, but I am on old farmland. I hear them in the trees at Franklin Park and have heard plenty about it on Nextdoor as well as watched the increase in the Cicada Safari App. They still are not at peak, so I expect to hear more, and your ground may crunchy at this point. The Washington Post had a great article on the Cicadas, and Kevin Ambrose made a great plot of what was reported by readers.
As far as the week goes, we will be down, then up, then down. Rain today will be light, but keep us much cooler than this last weekend. We will heat up on Wednesday and could see some strong to severe storms in the afternoon. The Storm Prediction Center has outlined the area with a marginal risk for severe storms. A Marginal Risk means that we have a chance for an isolated, short-lived severe storm.
By Friday a front looks like it will sag through the area and end up stalling in the area! That is not good for the weekend sunny outlooks of BBQs and pool openings! We may FINALLY get a little more significant rains, but the exact location of where the most rain falls is still up in the air. There is a concern it could shift south. You can see the current 7-day outlook from the Weather Prediction Center that highlights more precip to the south, which makes sense because the front will be hung up to the south.
The Long Range
Looks like after the cooler conditions this coming weekend, warmer than normal temps will return, but maybe some better chances of rain, which we need!
Outlook from the Climate Prediction Center and Graphics by Pivotal Weather
3/8/2021 – Loudoun Weather Outlook has Warmer conditions through Friday and then some cooling. We likely will break 70 Thursday, but believe Wednesday and Friday may break 70 as well! With warmer weather… HERE COMES THE POLLEN! Tree pollen starts popping! I know Juniper and Maple are already up and by Friday Pollen levels will be Medium-high for trees! The cooler air next weekend MAY bring some interesting weather Sunday/Monday of the following week with some mixing. I will watch but feel it is unlikely. The longer-range is showing colder than normal temps with above-normal precipitation, which is a change from this dry stretch and the brief warm-up this week.
Pollen Outlook Via Pollen.com
First – A Wintry Period will persist for the next two weeks. This could include multiple winter weather threats as well as some super cold temperatures at times.CONCERNS: Thursday and Thursday night keep fluctuating between a more snowy look and a sleety look. If it turns to icy, we could see enough for a sizable ice storm. It is possible the ice is sleet and not freezing rain which would be better! But someone in Northern and Central Virginia could see a significant ice storm. Please keep posted. BUT, it would be a good idea to prepare for potential power losses.
It is super difficult to figure it out, but I would say the confidence through early Thursday is that we are going to see snow. Mid-day Thursday through Thursday Night could be a constant switching back and forth and could end up dominant one type versus the other. The current look at the models leads me to think that we will be competing more with Sleet and Snow than Sleet and Freezing rain.
Saturday is low confidence now, but has possibilities!
Tough week ahead!
