Forecast: Weekend Storms, But When?

By Camden Walker

Best chance of rain is late Saturday into Sunday

* NatCast | PreaknessCast | For Parents, Weekend Rain is a Pain *

EXPRESS FORECAST

Today: Partly sunny. A passing a.m. shower? 40% chance p.m. showers/storms. Upper 70s to near 80. | Tonight: A shower or storm early? Mid-60s. | Tomorrow: A shower or two, then 60% chance of late-day showers/storms. Low 80s. | Sunday: Gray with showers. 60s. | A Look Ahead

FORECAST IN DETAIL

The good news is a good part of Saturday and the latter part of Sunday may turn out mostly dry. But everyone from backyard bbq chefs to those attending the Preakness may have to dodge periods of showers and storms late Saturday afternoon through midday Sunday. Some storms Saturday evening and overnight could produce heavy rain, high winds and hail. Wouldn't ya know it?... pleasant weather returns early next week.

Today (Friday): A foggy start to the day for many of us. After that, partly sunny skies and filtered sunshine is about all we can hope for between a few isolated showers. The moist atmosphere will make highs in the upper 70s feel somewhat muggy. The chance of isolated to scattered showers and thunderstorms increases for the afternoon and evening to around 40%. Hopefully those riding home for Bike to Work Day can dodge any wetness. Check radar before you head out just in case. Confidence: Medium

Tonight: The 40% chance of isolated to scattered showers and storms around dinnertime should decrease overnight. Mostly cloudy skies will keep lows fairly uniform throughout the region -- in the mid-60s. Confidence: Medium

Tomorrow (Saturday): Southerly breezes bring in even more humid air as highs warm into the low 80s. Partly to mostly cloudy skies could yield a shower or two but much of the day should be fairly dry. It's more the late afternoon when milky sunshine could fuel showers and storms (60% chance) into the evening. Some storms could turn severe with heavy rain, gusty winds and perhaps some hail. Confidence: Medium

Tomorrow Night: More showers and storms are likely, perhaps a washout. Temperatures drop into the 60s. Winds, outside of gusty thunderstorms, should be fairly light out of the southwest, keeping us somewhat muggy. Confidence: Medium

Sunday: A good chance (60-70%) of showers, but perhaps no storms? We can only hope. Highs will probably only get into the 60s. In the wake of a cold front passing through, increasingly breezy winds out of the northwest or north may begin to dry us out during the afternoon. Confidence: Low-Medium

Weekend rainfall totals could be in the range of 0.5-1", with locally heavier amounts possible.

A LOOK AHEAD

For Sunday night, breezes out of the north continue to dry things out and put a real chill on temperatures. Lows are likely to be in the 40s area-wide under clearing skies. Confidence: Medium

A lot of sun on Monday but, yes, a little cool. Highs in the mid-to-upper 60s. Confidence: Medium

More sun on Tuesday. And highs should increase to a more May-like lower 70s. Good weather for getting outside, and for drying out soil saturated over the weekend. Confidence: Medium

How's it looking for Ocean City this weekend?

I'm not a hard-core bike commuter, but I try to ride my 7.5 mile one-way commute from Annandale to Tysons Corner 2 or 3 times a week. I'll wimp out if the weather looks bad. Saw lots of riders taking advantage of Bike to Work day on the way in. Some of them were a little bit wobbly, but that's OK :)

Hey wiredog, OC looks pretty good; just keep an eye to the west at dinner time and... even later in the evening is when storms from the DC Metro Area may roll toward OC. Yet I think the ocean proximity will keep storms from being severe by the time they reach OC. Get out and enjoy the beach by midday just to play it safe!

Camden,
The best surf is in the morning, before 10 or so... Then the wind picks up. I'm usually off the beach by 3.

I go down every weekend...

Very muggy in the wake of last night's rain.

Biggest rain threat may be late tomorrow with the cold front. Sterling mentions a possible severe weather threat and isolated tornadoes to our north and west at that time. There could be an airmass shower/thunderstorm at any time through Sunday noon. Later Sunday, the biggest threat seems to be south and east of the area while areas to our north and west tend to clear.

We're planning to grill out tonight. I figure it won't rain for hours if it does rain here.
