LONG RANGE FORECAST THROUGH THE MIDDLE OF JULY - 7/5/2018
July is when we usually see summer come on with full force. There will be days and days of uninterrupted sunshine even in years with normal rainfall. Temps will begin to soar and hitting 100 west of the Cascades, with 90s east of them is very common. The average high in Medford for the month is just under 90 at 89. 70 would be a very cool day, and as for heat........well the all time highest temperature ever in Medford happened on July 20th, 1946 when it hit 116 at the OSU Agricultural Station which was south of Medford, and 115 at the National Weather Service office in Medford. Rainfall even in a normal year in Medford is just 3 tenths of an inch. Most of that, if not all of that, is usually the result of thunderstorm activity. Many years, even in wet ones, July can be bone dry..
Looking ahead to what we can expect through the middle of July we see what looks like hot temps coming beginning next week. Considering that averages at this time of the year will be in the 80s to near 90 west of the Cascades, and into the lower 80s east of them, it looks like we are going to be seeing 90s and possibly into the low 100s for the valleys of Jackson, Josephine, and Western Siskiyou Counties. The coastal areas also look as though they will be warmer than average. Could even see heat making it there. Especially the Curry County coast when Chetco Effects get going. For the mountains and east of the Cascades, expect very warm to hot temps as well with plenty of 80 degree readings. And, 90s should happen based on what the data is saying. Rainfall is expected to be sparse. What it looks like right now is a situation where we could see very isolated to very widely scattered showers and storms developing as the result of cutoff lows coming in. Mind you all of this could change. But right now the data and the trending seem very aligned in pointing us towards very warm to hot temps and little in the way of rain.
