Forecast: Bumpy Transition to Spring Continues

By Matt Ross

Spring becomes a bit more tangible this week as cold air masses continue to lose their punch. Nevertheless, jackets and umbrellas will be still be handy to have around as our seasonal transition comes at a price. Try to enjoy the typical late March weather. Before we know it, we will be lamenting the onset of heat and humidity.

TODAY

Sunny, seasonably cool. Mid to upper 50s. Today will be your standard issue late March day. Look for sunny skies with a freshening southerly breeze in the afternoon. Afternoon high temperatures will be near normal in the mid to upper 50s.

Overnight, skies will become cloudy as a weak storm system moves well to our north. A passing shower cannot be ruled out (20%), especially well to the north and west. Low temperatures will be in the upper 30s to around 40.

TOMORROW

Mix of sun and clouds. 60-65. Some morning cloudiness will partially clear during the afternoon. A mild westerly breeze will help afternoon high temperatures rise to the low to mid 60s.

Overnight, a few showers are possible (40%) as a pulse of weak, disorganized energy moves in from the west along a slow, northward moving warm front. Low temperatures will drop to the low 40s.

Keep reading for the forecast through the weekend ...

THURSDAY

Mostly cloudy, a.m. showers possible. Mid to upper 50s. Morning showers are possible Thursday (40% chance), possibly continuing into the afternoon to the north and west. Highs will be in the mid to upper 50s -- possibly higher south, especially if the sun comes out in the afternoon.

Partly cloudy skies overnight with a slight (20%) chance of showers. Lows should be in the mid 40s.

A LOOK AHEAD

The weekend looks a bit unsettled toward the beginning, before a drier, cooler air mass moves in for Sunday. There will be a chance of showers on both Friday and Saturday (40%) with highs in the low 60s, though neither day should be a total washout. Sunday should be moisture free and cooler with temperatures in the mid to upper 50s. Dry and chilly weather is on tap for the Nationals home opener Sunday evening.

Pretty chilly here in downtown DC among all the "circles"... low of 35 degrees at Scott Circle (16th&N, NW)

yes, the heat and humidity isn't far behind. I will take Matt's advice and enjoy this weather for the timebeing. oh yes.

....I actually like the heat (and humidity), but I'm one of those crazy people who is cold all the time.

A glorious crisp morning! Bright blue, sunny skies, birds singing, daffodils, forsythia, camelias, cherries all blooming. This area is so beautiful in the spring.

I recorded 18 degrees at 7 am this morning!

A good example of radiational cooling.

It has soared to 28 at 9:30.

Canadian lightning data for North America: Nothing, except for isolated activity in the Atlantic way offshore Delmarva. [The reason I prefer the Canadian data over other cloud-ground lightning detection sources is that it covers the ENTIRE North American continent north of Mexico, not just the U.S.!] (Other sources have more detailed data for the USA but tend to stop at our borders. StrikeStar is stilll a very good source, but recently HazardPredictor.com has gone to requiring payment or restricted access for its lightning data.) (In addition I'm looking through the WMO site for other foreign sources of lightning data. The Czech Republic has a very good source covering both the Czech Republic and Slovakia as well as nearby areas in Europe. That area, comprising the High Tatra Mountains and the rest of the Carpathian chain appears to be the "New Mexico of Europe" having the highest number of thunderstorm days of any area on the continent. The Slovak National Anthem begins "Lightning and thunder [Hrom a blesko] clash over the High Tatras". In addition the song "Hej Slovane" the call to Slavic brotherhood, contains the phrase "Hell and thunder [Hrom a peklo] will not deter us from achieving our goal!" Incidentally the Slavic text evokes the word "pogrom", which infers that the frequent anti-Semitic persecutions in many areas of Eastern Europe during the days of the Czarist regime descended upon the Jewish populace with a suddenness "like [nearby]thunder" ["po grom"].)

Looks as though my DanceCast is relatively dry. However I'm not sure about the extended rainy forecast for the rest of the week. Frankly I'm not too keen on these fronts which "hang up" just south of us and rain on us for a week or so!
