90s back in the forecast

July 6, 2015 - 05:40 PM

Did you know June 23rd was the last time Reagan National Airport reached the 90 degree mark? Neither did I. It's hard to believe it's been that long as it's still been warm and humid and highs did reach 89 and 88 respectively on June 30th and July 1st.

D.C. already reached the 90 degree mark 19 times this year and that number is expected to increase this week with highs around 90 Tuesday through Thursday, and again Sunday through early next week. Our area typically reaches 90 degrees 36 times per year, though we got off easy in 2014 when we only reached 90 degrees 24 times. We're readily approaching that number.

**On a side note, the hottest time of the year in D.C. is July 7th through the 22nd, when the average high peaks at 89 degrees. With that being said, Reagan National reaching around 90 this week won't exactly be exceptionally warm.

Another number you're probably sick of is that of the area rainfall which was the second highest total on record for June and so far doesn't want to take a break with 2.20" recorded so far in July. The month averages 3.73" so we're already running quite above normal.

Precipitation forecast for the next 7 days from the WPC

Looking ahead, rain chances look to continue with the best chance this week coming Wednesday. Unfortunately in this pattern we've kept a chance for showers and storms in Wednesday through Tuesday of next week. Don't worry, a washout of a pattern isn't expected as Thursday through Sunday appear mainly dry with only isolated showers in the forecast.

The heaviest rain will be focused over the Central Plains and into the Midwest where numerous Flash Flood Watches are posted for the possibility of 2-6 inches of rain.

4th of July holiday weekend weather in D.C.

July 1, 2015 - 04:42 PM

We've been receiving plenty of questions already about the holiday weekend and if the weather will pan out for outdoor activities. At this point, we're watching a trough of low pressure and associated frontal boundary settling into the D.C. area to end the work week. This will lead to chance for rain and a few storms Thursday and an additional chance for scattered showers and storms Friday.

Precipitation forecast through Friday evening

While we're not forecasting a washout locally, very heavy rainfall will be expected just south of D.C. If the boundary drifts slightly farther north, heavier rain can be expected through late Friday. For now, we're forecasting a 60% chance for showers and isolated storms Thursday with the heaviest precipitation south. Friday will feature a 50% chance for showers and storms with the best chances south and west.

Fireworks forecast

The 4th of July will continue to have its own chances for showers and storms. The forecast is currently looking at the possibility of a few isolated storms by the afternoon with the best possibility south and west of town. Latest guidance depicts more clouds than sun and isolated showers in the morning hours with some clearing by the afternoon. Temperatures are expected to reach the low to mid 80s.

For the fireworks displays, be sure to keep your phone handy with our Stormwatch 7 App or check Live Doppler radar before heading out so you'll be sure to be dry. If any storms develop our team will be all over them and will let you know where they are, where they're headed and when they'll exit. Don't forget about us on facebook and twitter!

Beach forecast for the weekend

Headed to the beach this weekend? The forecast calls for isolated storms Saturday at the northern beaches and a better chance for rain and storms for Virginia Beach and points south into the Outer Banks. Temperatures should be comfortable in the low to mid 80s. Conditions appear like they will continue to be unsettled on Sunday with a chance for rain and potential storms along the Mid Atlantic coastline.
