Most of Saturday is satisfactory
6:20 p.m. rainbow alert: Until the sun sets, watch for rainbows after any showers pass your location as you look east (with your back to the sun).

From 4 p.m.: Clouds have rushed in this afternoon ahead of a fast moving disturbance which will generate scattered showers and thunderstorms into the evening. Then we catch a break through Saturday afternoon when temps reach the 70s. That’s before more hit or miss showers into Saturday evening.
Through Tonight: Scattered showers and storms pass through the region late this afternoon into this evening - a few could contain gusty winds and/or small hail. Odds are about 30% you get wet, with the best chance (40 percent) of rain in the southern suburbs. After 10 p.m., any showers and storms should have moved away with partial clearing overnight. Lows range from the upper 40s in the cooler suburbs to the mid-50s downtown.
Tomorrow (Saturday): The bulk of the day really looks quite nice. We should awake to mostly sunny skies with some high and mid-level clouds holding off until the afternoon. By around 5 p.m., we’ll have a 30-40% chance of showers and storms returning. Before that, highs reach the very pleasant low-to-mid 70s.
Saturday night and Sunday: Showers are possible especially Saturday evening and Sunday afternoon. Despite these showers chances (at around 30-40 percent), it’s dry more often than not. Mother’s Day, while mostly cloudy, may include a few partly sunny intervals, with highs in the upper 60s to around 70.
Pollen update: Walter Reed says trees are HIGH at 470 grains/cubic meters and grass is moderate (for the region) at 3.5 grains/cubic meter.
