Meteorologist Melissa Frey’s Forecast Discussion:

You may have noticed the weather looks a bit different today! No clear blue skies, some are seeing light rain and the temperature is slow to climb. The rainfall totals as of 11 a.m. are shown to the right. (Click on the image for a full screen image.)Thundershowers developed over southern Oregon this morning and moved into Douglas County just before sunrise. Over 300 lightning strikes were reported over the southern Oregon Cascades as of 3:00 this morning. A few places saw light rain, but still nothing in Eugene. The day’s not over though.

The picture to the left shows the radar map along with lightning strikes in the past hour. (this was at 11:45 a.m.). Most of the rain shown here is evaporating before it makes it to the ground.

An area of low pressure is moving through Northern California from the Pacific. This has brought in enough moisture and dynamics to spark these thunderstorms over southern Oregon and across the Cascades and in central Oregon. This storm will very slowly move north this week, eventually moving into northern Oregon by Sunday. This means the thundershower threat will continue through the weekend. Highs will drop to the mid 80s today and low 80s by Friday.

The strongest storms will likely occur on Friday. This is also when the valley has the best chances for seeing thunderstorms here as well. Most of the week the valley will just see what’s left over from the storms, so clouds and possible light rain, but not much lightning.

Stay tuned to KEZI 9 News and the Stormtraker 9 team for the latest on these developing stories.

Have a great day!
