Warm October Weather, With Rain Ahead in Some Regions

Forecasts call for a warm start to October across Philadelphia, Omaha, Phoenix and southern Idaho, with varying rain prospects. Philadelphia is expected to stay sunny and warm through Saturday before a wetter system brings rain Sunday, linked to moisture from Tropical Storm Isaias. Omaha should remain warmer than average into the weekend, with strong winds Saturday and possible rounds of rain and cooler temperatures next week. Phoenix is forecast to be sunny and breezy, with highs in the mid-90s rising to the upper 90s next week; southern Idaho is expected to stay unusually warm and mostly dry, with lingering smoke. Broader outlooks suggest rain could become more likely around midmonth.
