Astring of picture-perfect autumn days will become a distant memory as the Rogue Valley transitions to rainy weather.
"It's pretty much the beginning of the end," said Brian Nieuwenhuis, meterologist with the National Weather Service in Medford. "The wet season begins."
On Sunday, a weak low-pressure system from the north blew out the high-pressure system that had dominated the valley for the past month.
Only 1/100 of an inch of rain fell at the Medford airport as the storm blew in and out quickly.
Temperatures that had hovered in the 70s during the day will give way to highs in the 50s and 60s through the week.
"On Friday night through Saturday, it should get a lot wetter and a lot windier," Nieuwenhuis said.
As of Sunday, the total rainfall for the season beginning Sept. 1 was 2.95 inches, or 1.5 inches more than normal.
However, October has been on the dry side. So far for the month, only .19 inches fell compared to the normal. .73 inches.
A storm system blew into the valley in September dumping more rain than normal. The last time it rained in the valley was Oct. 12.
For most of the time over the past month, the weather has been predictably cold in the morning and warm during the days.
"It got to the point where every day was the same," Nieuwenhuis said.
The rains expected by next weekend could dump a half-inch of rain in some areas during a six-hour period.
Snow levels could drop to 5,000 feet or lower, raising the potential of snow at some area passes.
Long-range trends indicate the area is in for a wetter pattern, which is normal for this time of year, Nieuwenhuis said. He said weather beyond seven days is difficult to predict accurately.
Until Friday, not much rain is expected in Southern Oregon except possibly along the coast.
