FORECAST IN DETAIL

The dreary weather of the past several days is coming to a close just in time for St. Patty's Day. Don't let the morning clouds fool you as the sun will be making intermittent appearances (dancing around like a leprechaun) by afternoon. Our best day of this week though is still Wednesday when we should see excellent sunshine and highs around 70. This is the spring of weather discontent though, and another cold front arrives on Thursday to make sure we start the weekend on the cool side once again.

Today (St. Patrick's Day): Slow warming and slow cloud diminishing is anticipated today with highs in the low 50s. Look for that sun to peek through this afternoon more often than not. Confidence: High

Tonight: Clearing skies will allow temperatures to dip a bit more. Look for lows in the upper 30s to low 40s mostly, but outer areas could surprise us to the colder side yet. Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Just like last week, Wednesday is our peak day of the week with regard to warmth. We should again see a brief appearance of near 70-degree weather throughout the area and the mostly sunny skies will keep us longing for better spring weather in April perhaps. Confidence: Medium-High

Tomorrow Night: Clouds will increase most likely with temperatures in the middle 40s. Confidence: Medium

A LOOK AHEAD

Thursday will mark the approach of another cold front. We should still see warm 60s for highs, but clouds and late day showers and maybe thunderstorms ahead of the front. We could use the rain, but it doesn't look like much with this system. Confidence: Medium

Friday is a colder day again as strong flow from the north ushers in Canadian cool air. Sun and clouds will be mixed together. We could see highs struggle to break 50 with morning lows in the upper 30s and temperatures Friday night into Saturday morning threatening the freezing mark (especially outside the Beltway). Confidence: Medium

The weekend starts on the cool side once more, but less cloudy/dreary compared to this past weekend at least. Highs are expected to be in the 50s on Saturday and then low 60s on Sunday. Lows should continue to be in the 30s though. Dry weather and mostly sunny skies should prevail. Confidence: Low-Medium

Current temp. in Burke: 39.6 and overcast.

HAPPY ST. PATRICK'S DAY!!!!

Hope everyone is wearing green today! (I am) Too bad it's not in the 70's today, because I'm actually wearing shorts for the first time in several months.

Spring is starting on Friday!

Rain potential next few days...up to a tenth of an inch Thursday. Thereafter, precipitation may be scarce through next Tuesday as sprawling high pressure builds in for the weekend and then some.

Warmer air could move in next week. The coming weekend looks like a keeper! High fifties to mid-sixties look like a good bet. Perhaps 70 next Tuesday/Wednesday.
