FORECAST IN DETAIL


We close Washington, D.C.’s warmest year on record (2012) with temperatures close to average but open 2013 with slightly cooler than normal temps on balance through its first weekend. We may see some spotty rain/snow showers New Year’s Day, but nothing of consequence. Then, despite highs in the 30s starting Wednesday, moisture is in short supply, shutting down snow chances.

Today (Monday): We begin the day with some sunshine and cold 20s. As the day wears on, we’ll see a slow increase in cloud cover but with a light wind coming in from the southwest (at 5-10 mph), highs reach the low-to-mid 40s. Confidence: Medium-High

Tonight: A cold front moves into the region, but generates only cloud cover with little threat of any precipitation. As we ring in the New Year, temperatures are in the mid-to-upper 30s with mostly cloudy skies. If there’s any precipitation overnight, it’s towards morning when there’s 20 percent of snow flurries or showers. Lows are in the low-to-mid 30s (suburbs to city). Confidence: Medium

Tomorrow (Tuesday): The proximity of a cold front and a bit of moisture streaming towards the region from south offers a slight (20-30 percent) chance of light snow and/or rain showers (rain most likely in the afternoon and even in the morning along and east of I-95). No snow accumulation is expected. Otherwise, it’s cloudy and seasonably chilly with highs in the low 40s. Confidence: Medium

Tomorrow night: Cloudy skies in the evening partially clear and it turns chilly as winds become out of the north and northwest. Lows range from 25-30 (suburbs-city). Confidence: Medium-High

A LOOK AHEAD

Wednesday’s partly to mostly sunny and tranquil, but cold, with highs 35-40. Some increasing clouds at night, with lows 24-28 (suburbs-city). Confidence: Medium-High

We’ll carefully watch a disturbance passing to our south Thursday, but current indications are that it remains far enough south that its only local effect is some cloud cover. It’s another chilly day with highs again 35-40. Partly cloudy Thursday night, with lows 21-27 (suburbs-city). Confidence: Medium

Friday through the weekend is partly to mostly sunny and cold with highs generally 35-40 and lows in the 20s. A pretty monotonous winter weather pattern...at least from this vantage point! Confidence: Medium
