This isn’t Seattle, but you could be forgiven for thinking so over the next few cool, cloudy days with frequent chances of drizzle and rain. At least the lack of freezing temps in much of the area means no wintry weather. Chances of seeing the “Long Night” full moon Saturday morning are pretty slim as that day shapes up to be the wettest day of the bunch.
Some models stretch the rains into Sunday with nearly two inches of rain! Early Christmas shoppers need to keep one hand free for the umbrella. While we may see few of them, the sunsets have reached their earliest point of the season, so light lovers take heart.
Today (Thursday): Clouds lose their strangle hold on the area briefly this morning as cooler drier air seeps in behind the cold front that pushed through last night. However, moisture streaming along that nearby front is likely to thicken afternoon clouds. Temperatures struggle to climb any higher than mid-to-upper 40s. Breezes are very light. Confidence: High
Tonight: A weak disturbance following along the frontal boundary could set off a few scattered showers (30% chance) in the middle of the night but amounts would be less than a tenth of an inch. Lows in the low-to-mid 30s are tolerable but early drivers well to the north and west of town be cautions about possible icy patches. Confidence: Medium-High

Tomorrow (Friday): The frontal boundary remains draped across the area and serves as a conduit for clouds as a storm takes shape in the Midwest. Moisture is still scant enough much of the day to keep shower chances low but, by late in the day, the probability grows to about 50%. Highs are held down by the sunless skies, with a range of mid-to-upper 40s. No wind chill worries as breezes are barely noticeable. Confidence: Medium-High
Tomorrow night: Clouds obscure the rising of the full moon and chances of light rain increase to 60% but do help to keep lows mainly in the lower 40s. Confidence: Medium-High
A LOOK AHEAD
Saturday is looking pretty soggy (80% chance of rain). While most models keep rain totals around a half inch some take the storm on a perfect path to give us an inch or more of rain. While shoppers are not likely to be amused, at least weekend yard workers get a solid excuse to relax. A southerly breeze ups temps a bit but highs are unlikely to do better than the upper 40s to lower 50s. Showers are likely to continue off and on through the night with lows in the mid-to-upper 30s. Confidence: Medium
Sunday is a tricky call as some models stall the shower system offshore and this keeps shower chances (40%) in place throughout the day. For now, look for a break in the afternoon for the Redskins game but no guarantees this far out. Highs only make the low-to-mid 40s. Clouds and a few showers remain possible through the night with lows in the mid-upper 30s. Confidence: Medium
Monday remains cloudy and continues to carry the risk of showers (30%). Highs do no better than low-to-mid 40s. Confidence: Medium
SNOW POTENTIAL INDEX
A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.
1/10 (→): Remote chance of coastal storm early next week, but probably not cold enough for snow if it forms.
