Tomorrow (Sunday): The good news is that rain chances are lower tomorrow, but we won't be able to totally shake them due to the proximity of a front, just to our east. Most of day will be dry, with storm chances - most likely in the late afternoon or evening -- only around 20-30%. It will be partly sunny and a little less humid, with highs in the mid-80s. Confidence: Medium-High

Tomorrow Night: Partly cloudy skies during the evening may become mostly cloudy by morning, as a wave of low pressure forms a long the front stalled to our east. Lows should range from near 60 in the cooler suburbs to the mid-60s downtown. Confidence: Medium

A LOOK AHEAD

At one time, Monday and Tuesday looked so promising weather-wise. Refreshing, Canadian high pressure was to build in from the northwest, giving us dry (low humidity), sunny days and clear, cool nights. Unfortunately, there are now signs that the weekend's front may not push far enough offshore for us to be in the clear. Instead, waves of low pressure may move up the front, giving us a chance of rain -- especially Monday. Conditions may improve Tuesday though some showers can't be ruled out, especially east of town. Highs both days will be below average, in the 70s. Confidence: Low-Medium
