Summer’s official start won’t send us the perfect weekend we’ve gotten used to of late, but it could be much worse. Consistent showers that moved into parts of the area last night should try to evacuate south and east before too long today, yet we could see additional isolated to scattered activity afterward, or not (simple, right?). Temperatures that are cooler today warm back up a bit on Sunday, though humidity stays fairly low.

Today (Saturday): Tricky down to the wire. Showers are around the region, but seemingly not in seriously impactful fashion locally. That said, with a front draped just south and moisture passing by, the risk is certainly there at times, and most consistently so in southern parts of the area. The period with the most numerous showers should be early morning, or into the first half of the day. After that, more isolated in nature. Cooler than normal temperatures are on tap, with highs mainly in the 73-78 range. Temps across the area nearer 80 are possible if we are on the dry side for the day and get into consistent afternoon sunshine. Confidence: Medium

Tonight: Look for clouds to want to continue to break at times through the night, but we may never do much better than partly cloudy. The slight chance of a passing shower or two can’t be dismissed either. Light northeast winds should keep us mixed up enough at the surface to hold drizzle at bay, but subject to change. Lows are in the upper 50s to mid-60s. Confidence: Medium

Tomorrow (Sunday): Clouds could linger into the morning, but the day trends toward mostly sunny as we go. With air filtering in from the north and northeast, temperatures are rather kind as well. Highs in the near 80 to mid-80s zone should feel pretty swell. The day wants to stay dry, but showers or thunderstorms over the mountains maybe send a few raindrops late, especially west. Let’s go ahead and issue a Nice Day stamp watch on this one. Confidence: Medium-High

Tomorrow night: Skies are mostly clear and temperatures plus humidity are still squarely in the comfortable zone. Definitely try to spend some time outdoors in the evening if you can! Like tonight, lows are again mainly in the upper 50s to mid-60s despite a slight increase in low-level moisture. Confidence: Medium

A LOOK AHEAD

On Monday high pressure is mostly in control of our weather, so plan on partly to mostly sunny skies. With all that sun, plus the continued push of warmer air from southerly winds, highs should again be a little warmer. Mainly low-to-mid 80s seems about right. I don’t presently anticipate much in the way of storm threat, but a random pop up is possible, especially nearest the mountains. Confidence: Medium

Tuesday brings summer back in more typical fashion. Humidity is up and so are temperatures, with highs reaching the mid-and-upper 80s across the area. Thanks to increased moisture levels, late day showers and storms are more likely than Monday. Maybe a 30% chance or so from here. Nothing to cancel plans over! Confidence: Medium
