FORECAST IN DETAIL

Although today’s weather may feel a bit chilly, it looks great for heading out to the polls to vote! Onto Wednesday, the much-discussed Nor’easter may end up just missing us. Even so, with clouds, unseasonably cold temperatures and a fading chance of rain and/or snow, it’s still probably the week’s worst day. Once the Nor’easter exits northeast on Thursday, high pressure builds in Friday with clearing conditions and warmer weather just in time for the weekend.

Today (Tuesday, Election Day!): Cold temperatures greet us this Election Day morning, with the thermometer reading upper 20s in the suburbs to low 30s closer to downtown. If you’re planning on voting early this morning, pack your coat and a warm beverage! High temperatures will mainly be in the upper 40s, with a slight chance of nearing 50 degrees closer to D.C. During the afternoon, winds from the northeast, though light, transport moisture and high clouds into the area from the low pressure system developing to the southeast. Confidence: High

Tonight: As clouds continue to increase overnight, temperatures will gradually dip into the mid-to-upper 30s across the area. The thickening clouds wil act like a blanket keeping temperatures from dipping below the 30 degree mark. Winds are 5-10 mph out of the northeast. Confidence: Medium-High

Tomorrow (Wednesday): Taking all details into account, the chance of significant rain and/or snow in the region Wednesday has fallen markedly. Still, it’s cloudy with a 20-30 chance of rain, highest odds east of town and most likely in the afternoon (if at all). If the precipitation works far enough west, it may mix with light snow. Temperatures will struggle to reach the mid-40s, while areas north and west may not crest 40. Winds are from the north, increasing to 10-15 mph. Confidence:Medium

Fun fact: these storm systems are called “Nor’easters” because they move northeast along the coast, and produce strong winds from the northeast that impact coastal areas; a suitable name indeed!

Tomorrow night: Any rain or snow (20-30 percent chance) will gradually taper off overnight as the storm exits northeast. Expect thick cloud cover, temperatures in the mid-upper 30s, and winds from the northwest at 10-15 mph. Confidence: Medium

A LOOK AHEAD

By Thursday morning all precipitation should be out of the area and clouds will decrease throughout the day. While Thursday looks dry, it will still be quite windy with winds from the northwest at15-25 mph and chilly with temperatures, from west to east, in the mid-to-upper 40s. Clear and cold Thursday night, with lows 26-33 (suburbs-city). Confidence: Medium

High pressure builds in by the end of the work week Friday bringing clearing skies, slightly warmer temperatures, and calmer winds. Temperatures should reach near 50 by Friday afternoon. Friday night is another clear and cold one, with lows 28-36 (suburbs-city). Confidence: Medium

After the cold, cloudy days during this week, the weekend weather looks fantastic. With high pressure firmly in place, expect clear and warmer days with temperatures in the mid-upper 50s on Saturday and possibly 60s on Sunday thanks to a shift to more southerly winds. Saturday night is clear but not as cold, with lows 30-38 (suburbs-city). Hang in there during the bleak days ahead, and look towards a lovely weekend! Confidence: Low-Medium
