The strong high pressure is pushing up the temperatures today from the Coast Range eastward. We are lucky here on this side of the Coast Range as we continue to see an onshore flow each afternoon that keeps our temperatures with the maritime influence, fancy way of saying, “cooler!”  Highs around our area will be in the mid to upper 70s with some of the protected areas reaching into the low 80s. As you proceed east, highs continue to climb. In the area where ODF is fighting the Cedar Butte fire, today’s highs will be in the mid and upper 90s, fortunately not much wind. The bad new is the Relative Humidity is going to be down around 30%.  As you continue east into the valley, their temperatures will be in the 100-105 range.

 There continues to be an Excessive Heat Warning for the Coast Range eastward until Saturday at 10pm. The usual associated cautions apply:  Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.  Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.
There is also another concern for those using our rivers and ocean for relief.  Be aware of surroundings and what the water looks like before you or your pets recreate in the water. Harmful algae blooms can increase in water bodies during hot weather, especially when the
water levels are low. The ocean temperature remains relatively low and as was experienced during the last hot period, this can result in loss of gross motor skills contributing to drownings, especially if you are caught in a rip current.
Tomorrow will be much like today but with the ridge shifting eastward, a little cooler with our highs in the low 70s, winds again westerly 4-8.  As for the weekend, the pattern will continue to shift as the ridge continues off to the east as an upper level trough of low pressure trough starts to move southeastward from the Gulf of Alaska, putting us under a southwesterly flow in the upper atmosphere, and gives us a stronger onshore flow down at the surface.  This spells a further drop in daytime high temperatures, both here and in the valley.  Weekend highs here around 70, 82-87 up near Cedar Butte and the upper 80 to low 90s in the valley.
As for next week, the trough moves across to our north Sunday giving the northern zones a slight chance of rain or showers into Monday thru Tuesday morning, otherwise, we may see some increased cloudiness here with highs warming from the upper 60s at the start of the week, into the low 70s by the middle of the week.
