FORECAST IN DETAIL

March can be a muddled meteorological mess with frequent flips in the weather from day-to-day. This week certainly demonstrates that theme as we go from the flurries yesterday (or accumulating snow, if you are well south/west of DC) to potential warm, near 70-degree weather by Thursday. But just when you think spring has sprung, we get smacked by another cold front- this next one just in time for Saturday.

Snow Potential Index: 0 (↓) - Cooler Friday night and Saturday again, but I don't see any accompanying moisture.

Today (Tuesday): Cold Canadian high pressure passes right overhead today and locks in some below-normal temperatures. Highs should range from the middle 40s to maybe near 50 in spots under mostly sunny skies. Light winds come from the northwest in the morning and then switch to come from the south in the afternoon. Confidence: High

Tonight: Mostly clear and still on the colder side with lows ranging from the mid-to-upper 20s in the outer suburbs to the mid-upper 30s in the urban heat island of the city. Confidence: High

Tomorrow (Wednesday): High pressure off the East Coast offers nice clockwise, “return” flow that pumps in warmer air, while still keeping the skies sunny. Highs should range in the upper 50s to low 60s with winds from the south and southwest at 10-15 mph. Confidence: High

Tomorrow night: A few clouds are possible, but the sustained flow of air from the southwest helps to buoy low temperatures in the warmer upper 30s to middle 40s. Confidence: Medium-High

A LOOK AHEAD

Thursday was the nicest day last week, and I believe we get a neat repeat this week with highs in the middle 60s to around 70 under partly sunny skies. Thursday night finds more clouds edging into our region with a chance (35%) of overnight showers too. Lows in the 40s to around 50. Confidence: Medium

Friday features another cold front just in time to cool the weekend - at least the first half. Showers and possibly some briefly heavier rain are favored in the morning up to around midday, with some clearing chances in the afternoon. Highs should range from the upper 50s and low 60s, but much will depend on how much cloud cover lingers into the early afternoon. Friday night trends colder and breezier with lows dropping down into the 30s under partly cloudy sky conditions. Confidence: Low-Medium

The weekend is trending colder at the start (sorry) with more likely below normal temperatures on Saturday (upper 40s to low 50s) under partly sunny skies and still breezy conditions. Saturday night sees another chance for a freeze with lows in the middle 20s in the outer ‘burbs to low-to-mid 30s in the city under mostly clear skies. Sunday shoves that high pressure offshore again, allowing for milder winds from the south and southwest. But only a slow warming is seen with upper 50s to near 60 favored. Confidence: Low-Medium
