Heavy rain overnight, severe storms possible Monday in D.C.

After a beautiful Saturday which featured our warmest temperature of the year so far at 84 degrees at Reagan National, it was much cooler Sunday. Easterly winds took over ahead of a warm front which kept highs in the 60s. Clouds were on the increase throughout Sunday approached from the southwest before finally getting to the D.C. Metro between 4pm and 7pm on Sunday evening.

Potential Rainfall Totals by Tuesday morning

Periods of rain continued overnight into Monday morning. Rain may be moderate to heavy at times with upwards of an inch possible by the time it exits the area during Monday mornings commute. A Flood Watch has been posted through Monday for the majority of the D.C. area. Winds were also breezy overnight, with gusts up to 30 mph.

Warmer air will filter into the region Monday ahead of the trailing cold front. Highs should reach the upper 70s to near 80 degrees Monday afternoon. This will elevate the instability levels across the region and the cold front will act as the lifting mechanism to create the chance for thunderstorms Monday evening. Winds aloft will be strong creating the chance for a few damaging wind gusts. This is why the Storm Prediction Center has placed the D.C. area and points south into a slight risk for severe storms.

The cold front will move east of the area Monday night into Tuesday morning and cooler temperatures are expected the remainder of the work week.

Stormy Afternoon and PM Rush

Don't be fooled by the cool, cloudy start today. A big change is coming.  A potent cold front that has a history of producing severe weather in the Midwest and Ohio Valley will arrive in D.C. Metro later today.  Be prepared for severe weather.  The most likely threat will be damaging winds.  

Severe Storm Impact

Hail around 1" in diameter is also possible in isolated storms along with heavy downpours. The threat of tornadoes is low.  The farther south you live, the greater your chances that storms will be strong. 

Severe Storm Risk Area

Any severe weather in D.C. would be isolated and short-lived.  Southern Maryland and Central Virginia has a 15% chance that a severe storm will come withing 25 miles of their home. The line of showers and thunderstorms should reach the I-81 corridor just after lunch time. 

Futurecast

By mid afternoon, it reaches the metro. 

Futurecast

By the late rush, it exits east of I-95 and then skies will clear out tonight.  This good news is that the severe threat is on the lower end of the scale today.  This same storm spawned a deadly tornado in Illinois last evening. Amazing video on You Tube you can watch here.  For us, be prepared to seek shelter indoors this afternoon.  Remember lightning can be deadly. Keep a close eye on conditions when the kids get home from the Bus Stop today.   The Stormwatch7 app here will help you stay informed with live radar updates and severe weather alerts on your phone. In addition, Chief Meteorologist Doug Hill will break into programming if necessary today if there are any warnings.  He starts team coverage with Steve Rudin starting at 4p on ABC7 News. Hang in there for the weekend!  It will be perfect with breezy conditions on Saturday. But sunshine and upper 60s to around 70 can be expected both days. Perfect for Cherry Blossom peak blooms!  Share your photos with me this weekend and early next week and I'll put them on the air during Good Morning, Washington!

Windy Saturday, Easter SUNday, Nationals Baseball is back!

Plenty of sunshine is expected this weekend but Easter Sunday still appears to be the better day of the two as windy conditions will prevail on Saturday.

Low pressure will continue to intensify as it moves into the Northeast tonight into Saturday morning. The resulting pressure gradient between the low and entering high pressure will make for windy northwesterly winds throughout the day. Winds may gust as high as 40 mph in the morning hours but winds should finally diminish Saturday evening. Temperatures will be cooler than Friday (which hit 71 degrees) with highs around 60 degrees.

Easter Sunday Hourly Forecast

Easter Sunday will start off rather chilly, with lows in the 30s in the outlying suburbs to near 40 degrees in town. Milder temperatures should enter by the afternoon with highs in the low to mid 60s. Winds may still be on the breezy side out of the southwest around 10-15 mph.

Nationals Baseball Forecast

Is anyone else excited for Nationals baseball? I am absolutely pumped for the season opener on Monday at 4:05pm. Weather conditions should be just about perfect for the game with temperatures in the mid to upper 60s throughout the day under partly cloudy skies.

Be sure to stay tuned to the latest forecast updates this weekend!
