A Vibrant Sunset Warning is in effect for the DMV region until 8:25pm local time.

At 7:32pm local time high clouds were sitting over much of northern VA, Maryland as well as DC. Vibrant oranges and pinks followed by reds can be expect in the warned area, especially between 7:59pm and 8:14pm. Use extra caution when driving to avoid getting to accidents as a result of being distracted by the sunset.

UPDATE: The Vibrant Sunset Warning that was in effect for the DMV region has been cancelled. The previous "forecaster" carelessly didn't account for the additional high clouds currently over Ohio that would lead to a much shorter period of sunshine shining underneath the high clouds over the region. This "forecaster" does not represent the real forecasters out there that alert the public about cool or potentially dangerous weather events. A Vibrant Sunset Warning should've never been issued. An advisory would have sufficed.

Looks like 2, maybe 3 days of 80s this week depending on timing of the cold front, then we cool to more typical temps for the weekend. Guidance has another upper ridge building over the east next week, which would again boost temps to above average- into the 80s, maybe a 90 at DCA as currently depicted by the GFS.

There is always payback for having some abnormal temps.  Last weeks chill replaced by more summer like heat.  80s tho.

Cool morning which will give way to warmth.  Full moon was sweet to look at driving in.

Hope the late week rain juices up. Want all the rain I can get going into the heat of summer.

We’re moving on Friday so I’m hoping for dry weather (or the rain holds off until the afternoon when the movers should be done).  GFS doesn’t give me much hope there though.

Hoping we keep the rainfall under 1.5". Don't want a big flood right during the spawn season for bass on the Potomac.

The trend, as you know, has been to decrease rainfall chances late week.  Will look to dry up as the week progresses as well. Rather low chances of anything meaningful as the sunlight lenght of day increases.  I expect the ramp up in ocean surf zone temps to pick up this week.

Lots of rain now might help a reservoir or deep water tables but it ain’t gonna help grass in July or August. The top foot of soil can dry out quickly in the summer sun.

I expect grass will brown and die sometime during the summer. But want well established roots for all my trees and perennials.

Those deep roots can help grass as well. The key, I’ve read, is deep watering, not shallow. Shallow water, shallow roots for grass. If that’s true I would think frequent small rain events in spring probably hurt grass come summer heat.

For all the warmth the next couple days this morning was pretty chilly

Yeap. Today's temperature range is going to be huge in spots that are currently cooler ( up to 40+F).

I'm looking forward to the AN temperatures.  Average high at DCA is now 71 so we'll be pulling +10 to +15 these next few days.

[Baltimorewx]

Perfect day today...I know itll be warmer this afternoon than some desire but dewpoints are low. This is what I was hoping for the weekend before last down OC lol. Oh well, will probably be back down in a few weeks

[Rvarookie]

So nice to be at ball fields tonight with temps in high 70s

[mappy]

absolutely beautiful outside

[H2O]

86° and sitting outside enjoying the warmth

[WinterWxLuvr]

LOL we don’t do anything gracefully. Couldn’t we do a couple of weeks in the low 70’s?

[Mrs.J]

Beautiful out! 85 with a light breeze. Younger Miss J is having her first after 5 lesson tonight. Nice weather and longer sun light is key.

We skip from  days and days of 58-62 straight to 85.

I’m already tired of the heat LOL

Went from heater to AC in a matter of 48 hours.

Its not bad this morning, nice temps.  But after being able to not run the a/c yesterday I'm gonna give up the fight today.  House will be too warm if temps are 85+

And the sun is where?

High Wind event possibly on the way - 

 

National Weather Service Mount Holly NJ
513 AM EDT Wed Apr 28 2021

In the wake of the front, a secondary vorticity lobe (stronger than
previously expected) is forecast to dive quickly south across the
region. This will be accompanied by a low-level surge in cold air
advection as the surface pressure gradient continues to tighten
behind the departing and intensifying low. West to northwesterly
winds will increase substantially as a result, especially into the
evening hours, as mid-level height falls and cold advection will
support efficient mixing to the 850-900 mb levels. Models indicate
winds speeds in these levels during this time increasing to 40-45+
kts. Expect sustained winds of 20-25 mph with gusts of 30-40 mph by
the afternoon hours, with gusts potentially increasing to the 45-50+
mph range during the evening hours. At this point, a Wind Advisory
seems probable for at least some if not most of the area, but given
the major shift in the forecast, confidence is not particularly high
on the details of this strong wind threat at this time. We will
continue to monitor this threat.

I think the forecast for sunny conditions today needs to be changed to cloudy conditions. Looks like thick clouds back to Ohio. I'm ok with not having a sunny 90 degree day anyway.
