Forecast: Not Bad for Much of Holiday Weekend

By Camden Walker

Warm & a bit humid through Memorial Day; Showers?

* BeachCast & Guide | NatCast | Traffic | Sun Safety: Don't Fry Day *

EXPRESS FORECAST

Today: Mostly sunny. Mid-80s. | Tonight: Partly cloudy. Low-to-mid 60s. | Tomorrow: Mostly sunny a.m. Partly sunny p.m., with isolated shower/storm? Mid-80s. | Sunday: Sun and clouds. 30-40% chance p.m. showers/storms. Low-to-mid 80s. | A Look Ahead

FORECAST IN DETAIL

As we head into the holiday weekend the pretty much perfect weather of the past few days will start to show some flaws. They'll be relatively minor -- in the form of higher humidity (but by no means oppressive) and low-range chances for showers and storms -- through Sunday. Monday may be more troublesome, though. All in all, highs near and above 80 should feel just right for the unofficial start of summer.

Today (Friday): Sunny and pretty darn delightful today with highs in the mid-80s and humidity a little higher, but still fairly low. Do you like this "broken record" of sunny days? Winds will be light out of the south/southwest. UV rays will be strong, likely in the "extreme" category around solar noon (1 p.m. EDT). Wear that sunscreen if you expect to be 15 or more minutes in the direct midday sun. Confidence: High

Tonight: Partly cloudy with somewhat mild low temperatures in the low-to-mid 60s. Overall, an uneventful evening. So head out with confidence that you can start your weekend without an umbrella! Confidence: High

Does this streak of amazing weather continue through Memorial Day? Keep reading for the forecast into early next week. Also, if you haven't already, join us on Facebook and follow us on Twitter.

Tomorrow (Saturday): We start out similar to Friday with mostly sunny skies and highs headed for the mid-80s again. But higher humidity -- edging toward the moderate range now -- could lead to increasing afternoon clouds and a chance of an isolated late-afternoon or early-evening shower or thunderstorm. Still, no reason to not move forward with any outoor plans you might have. Confidence: Medium-High

Tomorrow Night: Some batches of clouds could move through, but the rain threat (already rather slim) should dissipate after that chance of an isolated evening shower or storm. Lows should be in the mid-60s and feelin' a little muggy. Confidence: Medium

Sunday: Partly sunny with a little better chance (about 30-40%) of isolated to scattered showers and thunderstorms in the afternoon and evening. Temperatures will still feel warm -- highs in the low-to-mid 80s -- along with some mugginess. Confidence: Medium

Sunday Night: Evening shower/storm chances continue at around 30%. Overnight, lows should bottom in the 60s. Confidence: Medium

A LOOK AHEAD

The forecast for Memorial Day is still a bit up in the air. But as of now it may give us more trouble than Saturday and Sunday, with a fair amount of clouds and a 50/50 chance of an occasional shower or thunderstorm. Depending on how cloudy and showery we are, highs could be anywhere from the mid-70s to low 80s. Confidence: Low

The early outlook for Tuesday? ... much the same as Monday. So go ahead and re-read the paragraph above, but subtract a few degrees. Confidence: Low

BEACHCAST

Heading to the Delaware and Maryland beaches for the weekend? Looks good today and tomorrow with mostly sunny skies and highs mainly in the mid-70s. Sunday we're partly sunny with a late-day shower/t-storm chance (about 25%) and highs again around the mid-70s. Monday's forecast is not yet set in stone, but for now looks partly to maybe mostly cloudy with highs only near 70 and a chance of isolated to scattered showers.

Conditions look similar up at Cape May, N.J., but with highs in the low 70s through Memorial Day. Virginia Beach might escape the holiday weekend rain-free with mostly sunny skies throughout and highs near 80. And the Outer Banks may stay mostly sunny as well, though cooler with highs in the low-to-mid 70s through the long weekend. -Dan Stillman

What no mountain forecast for the three day weekend or a forecast for Berryville, VA? Your fellow blogger Dan Steinberg needs the forcast so he come out to the herding trials this weekend and lsoe his job!

Any hints about Blacksburg for Sunday? I'm doing a 100-mile mountainous bike ride. Wunderground is saying 30% change of afternoon thundershowers. I probably wouldn't mind a little bit of that action :)

Hi guys, for the Blue Ridge mountain/valley region overall, I would subtract 5 degrees in temperature and ADD 5 percentage points for showers chances.

I know it's totally out of your jurisdiction, but any thoughts on Boston weather Saturday and Sunday? We have an outdoor wedding to go to and I don't know which forecast to trust... Thanks!

Feels like those early morning 30s and 40s and daytime highs in the 50s finally are gone until fall...

Boston Weather Sat pm: Cloudy and cool, with a slight chance of showers. In the mid-60s. Becoming partly Sunday by Sunday afternoon, with temps reaching the mid-70s.

Nice area of scattered cirrus clouds this morning but not increasing as usually happens when a strong low pressure area is approaching. Tonight begins five days of evening dances and much of the rain is supposed to be scattered or isolated later in the weekend, but afternoon/evening storms do tend to occur when I'm trying to get dance transportation.

The system in the Gulf of Mexico is expected to feed moisture into the eastern U.S. eventually.

Has anyone seen any fireflies yet? I haven't but the earliest fireflies have generally appeared in May during or before Memorial Day weekend in years past. This year's wet spring should be good for the fireflies.

It's a fine start to the holiday weekend out there right now. Have a good one, whatever your plans may be.

I just saw my first firefly out on a walk this evening! There was only one, and he refused to be caught!

Beautiful evening. Not too humid out there at all.
