D.C. area forecast: Murky March weather pattern next few days

1 p.m. Update: Not much rain around so far today, even less than the not-terribly-rainy forecast below. Still, don’t be surprised if a few showers pop up during the afternoon. Some breaks in the clouds have helped highs warmer than forecast as well, well into the 50s in many spots. Not bad at all.

FORECAST IN DETAIL


If you like warm March sun and clear-cut weather forecasts, well you may not want to read any further. A generally unsettled pattern sets up shop for the next few days with plenty of clouds and occasional showers. Yet, much of the time rain may be light and spotty. Some snow or sleet might mix in Sunday night into Monday morning, but it looks too light to cause much trouble except far north and west of D.C.

Today (Saturday): The threat of light showers is with us through the day, as are mostly cloudy skies. Showers look to be steadier in the morning than the afternoon, when rain may be spotty with dry breaks as well and highs in the upper 40s to near 50. Hopefully Rock’n’Roll marathoners don’t get too soaked out there. Rain totals are probably around 0.25” or less. Confidence: Medium

Tonight: Any showers should exit by mid-evening. Partly to mostly cloudy skies linger through the night as lows range through the 30s. Confidence: Medium-High

Tomorrow (St. Patrick’s Day): Fingers crossed we get the luck of the Irish and stay dry through much of the day. The morning at least has a good chance, as our next rain threat only slowly edges closer from the west. We’ll bump the chance of light showers to 20-30% for the afternoon just in case. Highs aim for the mid-40s under partly to mostly cloudy skies. Confidence: Medium

Tomorrow night: Precipitation chances increase to around 50%, and that could mean a mix of rain, sleet and snow as lows dip back into the 30s. But even if we do see precipitation of the wintry variety, it’s likely to be light and mostly inconsequential. Confidence: Low-Medium

A LOOK AHEAD

Monday shower chances rise to 60%, with mostly cloudy skies holding highs to the 40s. A bit of snow or sleet may mix in during the morning especially north and west of D.C., but you probably have to get pretty far north and west (i.e., northern Frederick, western Loudoun and points north/west) for any impact. Precipitation is mainly light and perhaps intermittent, until a cold front tries to drag through a heavier line of showers Monday evening into overnight, as temperatures stay mainly steady in the 40s. Confidence: Low-Medium

Tuesday is wait-and-see at this point. That is, can’t say yet if the cold front and rain chances are outta here by the time we wake up and head out the door, or if they linger into or through the morning. By afternoon we’re breezy, but sunshine should increase and help boost highs well into the 50s. Confidence: Low-Medium
