A new month begins with a mix of seasons continuing across the U.S. The East is locked in late summer while autumn tries to take hold elsewhere.

The WeatherRadar shows two systems causing trouble today. The biggest one is rolling into the West Coast, where heavy rain will soak northern California, Oregon and Washington, including Portland and Seattle. The highest elevations of the Cascades, seen with the pink hues on the WeatherRadar, will have to contend with snow from this system. Afternoon highs will only be in the 40s and low 50s.

Meanwhile, a cold front moving out of the Ohio and Mississippi valleys will become stationary from the Texas Gulf Coast northeastward into the central Appalachians. This will produce a few scattered showers and even a rumble of thunder early in the day before the showers become more widely scattered later in the day. A few could make it into the Mid-Atlantic and southern New England later today as the front edges through.

It still feels like summer across the East and South. The TemperatureRadar shows highs in the 80s will be found in the South, Southeast and up the Atlantic Seaboard into the Mid-Atlantic. Washington, D.C., Baltimore, and New York City could hit 80 degrees this afternoon before the front arrives. Even Boston will be in the upper 70s under a mostly sunny sky.

Autumn is locked in the western U.S. Even with abundant sunshine across the Rockies, Southwest and southern California, afternoon highs will only be in the 50s, with parts of the Southwest reaching the 60s and low 70s.

The main tropical development zones remain quiet, but a broad low-pressure system in the western Caribbean needs to be monitored. It has been watched all week and there is still a chance something develops this weekend.

No other tropical development is expected over the next several days.

It's never too early to prepare for the winter season! Is your blizzard kit in order?
