Next Few Hours
Extended Outlook
Chilly, unsettled weather to open the new month of November Saturday.
Saturday Upper Air Flow
A “pool of very cool air aloft” will be present nearly right over us. This pocket of cooler than normal air higher in the atmosphere resides 10,000 to 20,000 feet above sea level. It’s likely this will increase instability and contribute to the development of scattered showers at times on Saturday.
Saturday Model Snapshot 4 p.m.
Showers will be present but scattered. This graphic depicts the scattered nature of the showers likely to come and go on Saturday along with varying sky conditions.
