LONG RANGE FORECAST THROUGH THE END OF NOVEMBER - 11/20/2017
November is usually the month where the rainfall starts coming in earnest. Average highs for November in Medford are in the 50s. 50s and 60s are very typical for November at the beginning of the month. By the time you reach the end of the month, 40s for highs are not uncommon at all. Frosts will have certainly occurred over all but the coastal areas. Average rainfall for Medford in November is at 3 inches. The coastal areas will typically see 5 - 7 inches of rain in November. November is also when the snowpacks start building in the mountains. Typically November will bring 2 - 3 feet of snow in the mountains above 4000 feet.
The Climatology Center is forecasting November to be near average for both temperatures and precipitation.
So what can we expect through the end of the month?
We are expecting to see above average temperatures. This means that we will likely be seeing highs in the 40s and 50s where we should see 40s west of the Cascades. East of the Cascades temps in the 30s and 40s are to be expected for highs. Typically highs would be locked in the 30s. The Coast will be closest to average with highs in the 50s to even the 60s. Overnight lows are looking to be above normal as well. We are not expecting to see an arctic air masses arriving so that should hold temps up at night.
Rainfall and snowfall is expected to be above normal to start the period in this week of Thanksgiving. But, as we hit the final days of the month, we are looking to see a decrease in moisture coming in. We are not expecting to see snow that causes widespread travel issues fo the rest of the month. It looks now like travel could be rough at times due to snow around Crater Lake and Diamond Lake, but not much of a problem elsewhere. Back to the moisture, the data is leaning to us being about 50 percent of average over the last seven days of the month. Not expecting us to be dry. But will see less than would be typical.
