PM Update: Enjoy the Clear Sky While it Lasts

By Ian Livingston

Cloudier and unsettled pattern returns Wednesday

* What Weather Features Interest You? | Wx History: Snow in 1990 *

A cold morning became a cool afternoon today. But on the bright side, lots of sunshine was on display. Just a few high clouds are spreading across the area this afternoon as temperatures top out in the upper 40s. Winds that were blowing from the north this morning have lessened in intensity this afternoon and become variable. We'll see fair conditions continue through the evening as temperatures fall through the 40s and into the 30s.

Tonight: A near-repeat of last night is scheduled tonight, with temperatures perhaps a smidge warmer. Lows should range from the upper 20s in the colder suburbs to right around freezing downtown. Mostly clear skies early will transition cloudier by morning as winds remain light.

Tomorrow (Wednesday): Wednesday will feature more and more clouds after a partly sunny start. It will once again be cool, with temperatures rising to around 50. By late afternoon or evening, some light showers may be approaching from the west, but most of the rainfall should hold off till the overnight hours.

Alaskan Volcano: Alaska's Mount Redoubt awoke this weekend and has erupted six times so far, with more expected over the coming weeks and months. National Geographic shares some imagery from the event, including pictures of a spectacular mud flow caused by melting snow and a satellite shot showing where ash has fallen in the Alaskan wilderness. Past volcanic eruptions in Alaska have produced spectacular sunsets throughout the northern hemisphere. As Redoubt continues to erupt, it's something worth watching for.

BWI and Dulles missed by 1°, but National hit 50°. Sub-30° lows tonight will be a real stretch with the clouds moving in and a more southerly wind component.

Near-term precipitation outlook per Crown Weather Services: Up to 0.50" Thursday, and possibly up to 0.10" Friday. Triple-point passage near here during the weekend still looks on schedule. Expect showery rain, possible thunderstorms, and possible severe weather in favored areas with the weekend storm. Favored area most likely to be south and east of the District.

Still too cold for late March. Brrrr.

@sock-pupet: Considering it's 2:53 and I'm at 36.3 here in Rockville, I would think you're right.

Temperatures fell into the upper 20s in many spots last night despite the clouds.

Last night's lows: DCA-34, IAD-27, BWI-25. I'd say Ian's forecast was pretty close to spot on, unless you want to quibble with plus or minus 2 degrees.

You want nit-picking? Here's world-class nit-picking:

Hey Steve,

Fyi ... I went with "partly to sometimes mostly cloudy" in my forecast for tomorrow based on a lot of BK and OV in the MOS guidance, easterly flow, and decent 850 RH and VV. I saw you went mostly sunny and I do see that MOS has worked some SC into the picture and it's not clear whether it will be due easterly flow or more southeasterly like today. Though there's still a good bit of BK and OV in the MOS guidance and decent 850 RH. Anyway, just wanted to explain my rationale in case you decide you want to scale back from mostly sunny (maybe partly sunny?). I'll let you decide if you want to change as I don't have enough confidence in the forecast or models right now to warrant making the change myself.

Thanks for letting us know about tomorrow. Enjoy the meeting.
