Abundant clouds, periods of rain, and winds off the ocean have all helped keep us much cooler than normal for mid-July around here. Humidity has only slightly abated, but when it’s in the 70s, we can’t expect too much more. Fortunately after last night, most of today’s rain has been spotty and not terribly intense.

Through Tonight: Periods of showers with isolated thunderstorms remain likely (60% chance) through the night, though the risk should diminish overall as we get into the pre-dawn hours, if not prior. Some heavy rain is still possible, but a repeat of last night seems unlikely. Lows mostly range from the upper 60s to low 70s, which isn’t much cooler than our rain-cooled daytime temps!

More sun than today on Saturday, but plenty of clouds as well. We should remain under enough influence of cloudiness, rain threats (50% chance) and an east wind (around 10 mph) to keep temperatures from soaring. Any rain that falls may be heavy at times. Highs are generally in the 82-87 range. Dew points are back near and above 70, so any slight humidity hiatus is over. Winds are light from the southeast.

By Sunday, the heat starts ticking back up as a ridge of high pressure builds in more strongly. Skies are partly to mostly sunny, with just a slight risk of an afternoon shower or storm. Plan on highs reaching the upper 80s to low 90s. Humid, too.

Typhoon Soulik: Taiwan is ground zero for Typhoon Soulik’s first landfall. From there it is expected to hit mainland China in a weakened form. The storm made landfall in mid-afternoon EDT across far northern Taiwan with winds around 100 mph. Torrential rains have inundated large parts of the region. Check out two images of the storm on approach:


Pollen update: The most recent pollen count was washed out by rain. Mold spores should continue to remain high, perhaps moderating if we dry out this weekend.
