LONG RANGE FORECAST THROUGH THE END OF JUNE - 6/17/2019
June is both the final part of spring and the beginning of summer. Summer begins this year on Friday, June 21st. This is the longest day of the year by daylight in the Northern Hemisphere. At the same time, it is the shortest day of the year, the first day of winter, in the Southern Hemisphere.
June typically is a very pleasant month. Average highs are in the 80s for for the valleys west of the Cascades. 70s do happen frequently, and 90s are common. Hitting 100 is also seen in warm years. 60 degrees would be a very cool day. East of the Cascades you mostly see 70s with some 80s thrown in. Days with temps in the 60s can happen. Days with temps in the 50s would be a very cold day. Especially later in the month. The highest June temp ever in Medford is 111 which happened in 1944. Average rainfall slides below an inch for the first time in the calendar year on average for Medford. Medford usually sees just over a half inch of rain. Most often that is the result of convective showers and thunderstorms.
Looking at what we can expect through month's end, both the temperature projections and precipitation projections are identical. Both indicate a high percentage chance of happening. In the case of temps, this would be cooler than average. And in the case of precipitation, wetter than average. This is tremendous news if you are sick of the smoke. If we do see what is projected, you can be sure we will NOT be seeing smoke in June that would be harmful to us in anyway. That is the great news. So the impacts here are going to mean where we should be enjoying a lot of 80s and even into the 90s west of the Cascades, be expecting to see more 70s and 80s. Still very pleasant. East of the Cascades this is going to likely mean mostly 70s. Could be seeing up around 80. And we could be seeing some 60 degree days too.
For precipitation, we are going into the dry months now through September. It truly does not take a whole lot of rain to get us above average. So, while we have higher percentage chances of seeing above average rainfall, do not take that to me serious rains causing major impacts. While I cannot totally rule that out right now, i think what will be far more likely is to see much more widespread and persistent shower activity than what would be normal. All in all, i think we are really going to like the rest of the month. No serious heat being seen anywhere at all. And, this is not a forecast that shows fires becoming an issue at all.
