Our weather penance is almost paid, after potentially locally flooding rains remaining possible today. The weekend has drier air for us to enjoy, and sunny skies should help the ground dry out a bit too. Remain cautious today and do NOT drive through standing water. Turn around, don’t drown. You wouldn’t want to miss the upcoming glorious weekend, seriously.

Today (Friday): It’s still warm, humid, and mostly cloudy. Light south-southwest breezes under 10 mph offer little sweat reduction as high temperatures still manage to get into the 80-86 degree range. Morning rain chances (40%) increase by afternoon (near 80%) as a cold front marches west to east across the area. We may have a bad evening rush situation, hampered by rain. Over a quarter inch of rain is possible in heavier thunderstorms. Should a downpour stall, please be mindful of low-lying areas as we could have a localized flood risk develop quickly. Confidence: Medium-High

storm threat

Tonight: Heavy showers and storms linger (50-60% chance), so could our flooding threat. As we get to and through sunset showers and storms should wane with clearing and lower humidity being ushered in over night. We have at least a chance we glimpse the full Honey Moon. Low temperatures range from upper 50s in western areas to mid-60s downtown. Confidence: Medium-High

Tomorrow (Saturday): Rise & shine with the earliest sunrise of the year (5:42 a.m. downtown) under mainly clear skies. Get outside and enjoy the less humid, drier air with blue skies (remember sunscreen!) and slightly less heat. Refreshing northwesterly breezes feel great as they blow around 5-15 mph. High temperatures around 80 to mid-80s will feel much better than yesterday’s similar range. Confidence: High

Tomorrow night: Breezes should calm, skies remain fairly clear, and temperatures drop into a comfortable range. Even downtowners could open their windows? Low temperatures under this drier air mass could dip into the mid-to upper 50s, with lower 60s downtown. We’ll take it, right? Confidence: High

Sunday: This still holds up as a salvageable summer’s day with humidity remaining under control for the most part. We have plenty of sunshine and just a few afternoon clouds it looks like. Get outdoors, just consider a hat, sunglasses, and the usual sunscreen. High temperatures in the 82-89 range appear likely. Confidence: High

A LOOK AHEAD

Sunday night: I think clear skies and comfortable temperatures — for one last night! — warrant some dinner al fresco or even some last yard work chores. Low temperatures in the low-to-mid 60s may not beg for open windows, but you may be able to escape turning on the A/C. Confidence: High

Monday’s looking like we are back to summer for sure, with a ratcheting up of both heat and humidity. I guess if you are at the pool or beach you wouldn’t mind temperatures in the mid-80s to around 90. But that sun could beat down on us, unless a few thundershowers manage to cool us off (10-20% chance). Confidence: Medium

Tuesday’s shower and thunderstorm threat increases to about 40%, overall. Mostly sunny skies outside of some of the bubbling storm clouds that may percolate could feel a bit steamy with high temperatures popping up into the upper 80s to low 90s. I expect fairly high, muggy dewpoints around 70 or higher, so please drink that water and find some air conditioning. Confidence: Low-Medium
