The cloudy skies, raindrops and lightning strikes that Rogue Valley residents experienced this morning are just a precursor to a bigger system moving north through Southern Oregon today, the National Weather Service reports.

Currently the weather system is moving across the Mendocino Coast in Northern California, and is expected to arrive in Southern Oregon this afternoon. According to the National Weather Service, clear weather is expected after the first wave of thunderstorms this morning, but the clear skies will allow heating to help generate another round of thunderstorms as evening approaches.

Scattered showers and thunderstorms are expected into the evening, said Megan Woodhead of the National Weather Service. The storm could produce small hail and gusty winds, but most of the precipitation is expected in the mountains, with only a 25 percent chance of rain in Medford, Woodhead said (This figure has been corrected).

A red flag warning, alerting people to the potential for "explosive fire growth" because of lightning and little rain, is in effect across the region until 11 p.m.

The storms are expected to start across southwestern Siskiyou County and move north to northeast into Southern Oregon. By Thursday, the system will have moved through the Rogue Valley with some rain expected on the east side of the mountains in Klamath and Lake counties, Woodhead said. Normal summer highs near 95 degrees are expected Thursday.
