There are quite a few raindrops in the foreseeable future, but as Camden noted yesterday, at least it won’t be mixed with any major chills in the air. After all that nice weather of recent, by the beginning or middle of next week, many may be wondering if the sun will ever return in full force. I wish I could say there was a light at the end of the tunnel but we’re still a little too close to the entrance to say that with much confidence.

Today (Saturday): If you’ve got some outdoor weekend plans, prepare to dodge a shower (50% chance), but I think we may actually end up having a fairly rain-free daytime after some potential morning activity. Still, raindrops want to surround the area, so certainly check radar before doing anything extended outside. There could be a thundershower late day as well. High temperatures are a bit tricky and dependent on how much clouds we see. More puts us in the upper 60s, less means well into the 70s. So, a good middle ground seems to be near 70. Confidence: Medium

Tonight: Skies remain mostly cloudy, and showers are probably a little more likely during the evening and night than during the day, about a 60% chance. Those dewpoints near or above 60 keep us muggy through the night and halt significant temperature falls. Look for lows near 60 into the mid-60s. Confidence: Medium

Keep reading for the forecast through the beginning of next week...

Tomorrow (Sunday): Winds from the south continue to pump in the warmth that mainly ends up limited by clouds and showers/thunderstorm chances. Coverage may be a bit more widespread than Saturday, but probably still pretty hit or miss. An isolated storm could be strong or severe. We should add a few degrees from Saturday, so mid-70s work for many. Confidence: Medium

Tomorrow night: It’s pretty cloudy again other than a few peeks of stars here and there. Showers are also possible, but they’re probably more isolated through the night. Did you enjoy the temperature forecast for tonight? You’ll like this one then too. Lows fall to near 60. Confidence: Medium


On Monday we’re mostly cloudy with a continued chance of scattered showers or thundershowers, probably focused on the late day. Who’d have guessed it? Highs again head toward the low-to-mid 70s. Confidence: Medium

Tuesday? The broken record plays on and on (for now) as highs should range from near 70 to the mid-70s. And of course, there’s that daily threat of scattered showers and thundershowers. As with previous days, some spots may stay dry, but probably not everyone. Confidence: Medium
