FORECAST IN DETAIL

Another excellent day graces our region today with sunshine and warmer-than-normal temperatures. Clouds creep back into the picture tonight and tomorrow along with light snow or rain. Thursday and Friday go back to fairly nice conditions with just-above normal temperatures, but a series of disturbances and cold fronts push us into real winter this weekend. We have a shot at flurries/sprinkles on Saturday, while Sunday could get much colder.

Snow Potential Index: 4 (↑) - Chances for light snow have increased Wed - small margin for error, maybe flurries Saturday.

Today (Tuesday): The nice air mass that brought temperatures into the low-to-mid 50s yesterday should continue to moderate today with additional sunshine. That means we are able to safely add a few more degrees and expect mostly middle 50s and maybe a few upper readings today. Mostly sunny skies and light breezes at about 5-10 mph from the west and northwest prevail. I believe this is the nicest day of our week. Confidence: High

Tonight: Clouds roll back over our area, which helps low temperatures hold a bit warmer. Minimum readings in the upper 20s out in the outer suburbs contrast with low-to-mid 30s in the city. The District probably doesn’t see the freezing mark tonight. Confidence: Medium-High

Tomorrow (Wednesday): A disturbance moves through and offers the chance of light snow or rain. Snow is favored from the District and points north and west with a rain/snow mix or just rain more likely south and east of town. A little accumulation is possible, mainly in the colder north and west suburbs (in places like Leesburg and Frederick). The margin for error is small here, and if the disturbance jogs north a bit, we’ll see mostly just light rain. Clouds dominate as the sun takes a “time-out”. Highs are just 35-40. Light winds. Confidence: Medium-High

Tomorrow night: A few snow showers may linger into the early evening; otherwise, gradual clearing overnight as low temperatures drop a bit farther into the mid-20s in the outer suburbs to low 30s in the city. Confidence: Medium-High

A LOOK AHEAD

Thursday returns high pressure to the region, but the air mass is a touch colder than before, so we probably only get to the upper 40s to around 50 (hey, it’s still slightly above normal for this time of year). Mostly sunny skies are back in action. Mostly clear and cold Thursday night with lows in the mid 20s to low 30s again. Confidence: Medium-High

Friday finds us in the same air mass with mostly sunny skies again and slightly warmer temperatures- probably low 50s in most spots. Friday night features increasing clouds, but low temperatures should still manage to reach down into the 20s outside of the Beltway to lower 30s in the city (risk is warmer if cloud cover moves in faster). Confidence: Medium

The weekend is tricky yet again. The safest thing we can say is that it turns colder. Saturday should see highs in the 40s with partly cloudy skies. A disturbance moving through the area could trigger some showers that could be another rain/snow mix story- but precipitation stays light again. Partly cloudy skies Saturday night with lows in the 20s to low 30s. Sunday may find us getting scraped by a much colder air mass that passes through the Great Lakes and Northeast. Some guidance suggests we only get highs in the 30s under partly cloudy skies (maybe another flurry chance?). Sunday night could see a harder freeze with temperatures dropping into at least the teens. Finally, we still can’t rule out the possibility of a coastal storm, but indicators aren’t strong. Confidence: Low-Medium
