PM Update: Clouds and Showers Replaced by Cold

By Ian Livingston

Partly sunny, chilly and breezy on Tuesday

* Do Solar Storms Threaten Life as We Know It? *

Showers and thundershowers of this morning have all pushed east this afternoon and we are now left with some breaks in the clouds and a few more showers along the cold front now moving to the east of D.C. Abundant breaks of sun earlier will temporarily be replaced by mostly cloudy skies again for a period this afternoon into evening, but an overall clearing trend should continue overnight. Highs that reached into the low-and-mid 60s today are warmest we'll see for a few days.

Tonight: Skies will slowly clear out overnight and temperature will be quite cold. Lows should tumble to the mid 30s in the suburbs to around 40 in D.C. Winds will also pick up from the northwest adding a wind chill to the air throughout much of the night.

Tomorrow (Tuesday): We will see plenty of sunshine along with rather chilly temperatures on Tuesday. Cold air aloft will allow for some cloudiness to form during the warmer part of the day, and periods of more clouds than sun are possible. Highs look to only reach into the upper 40s to lower 50s. A gusty wind from the northwest will continue making it feel colder than it is.

Where Have All the 80s Gone? Though temperatures last month ranged only from near-normal to slightly below, no 80 degree readings have occurred at National Airport this year. Over the past 60 years, the median date for the first 80 degree reading is right around April 4. Over that time period, the earliest occurrence was March 1 in 1976 and the latest was May 14 one year prior, in 1975. Last year, our first 80+ (82F) came on April 11. With no 80+ degree readings easily seen -- though growing more likely -- on the horizon, when do you think National will get there?

I'm guessing Tue, April 28.

No 80-degree days yet this year? Gee, Al Gore won't like that.

Latest from Channel 9: Nothing but fifties or lower through Easter.

Still uncertain how much rain falls Friday/Saturday. It's supposed to be a swing dance night w. Natty Beaux @ Chevy Chase despite the fact it's Good Friday.

I'll say May 1st for the first 80F day.

After a high today of 63F here on the Blue Ridge east of Front Royal, we are down to 42F currently. It will be interesting to see if any snow showers develop around 4 or 5 am. With the ground warm, I am skeptical of any accumulation.

I'm thinking we gotta kick this pattern sometime in the next two weeks, so I'll go with the 20th of April on my guess.

Current temp. in Burke: 46 exactly and overcast.

I'm just going to give a wild guess:

April 28

Oh, whoops!

Someone already guessed that date.

Well, I'm going with April 30.

Based on 50 years of data, the chance of a high temperature of 80°+ on any given day in April is less than 13%.

Bedtime update: 37F on the Blue Ridge east of Front Royal. Sue Palka just mentioned 3-5" lake effect snow further west on the upslope mtns.

If anyone has a day off, it could be a good time for last minute xc skiing at Whitegrass.
