Most of us had very mild and comfortable conditions on Thursday afternoon, but low pressure to our North has brought some showers and thunderstorms to areas of Siskiyou and Modoc Counties today. Skies have been sunny to mostly sunny for most areas with the exceptoin of higher elevations closest to the Oregon border. Clouds will be increasing in our Northern zones this evening. Temperatures have mostly topped out in the low 80's in the valley, in the 60's to low 70's in the foothills, and in the 60's in the mountains .Winds have been out of the Southwest to around 10mph this afternoon, and humidity values have stayed above 25 percent. We'll see the chance for some scattered showers in the Northern Sierra this evening, and a very slight threat of showers popping up in the North valley.
Low pressure will be centered to our East on Friday and that will result in slightly cooler temperatures and gusty North winds. The gusty winds and low humidity will elevate fire danger in our region on Friday. Sustained winds will be out of the North to around 25mph, and we'll have the potential for gusts up to 35mph. Humidity is projected to drop into the 10 to 20 percent range by Friday afternoon. Fire danger will be in the moderate to high range, but would have been even higher if we didn't have the wet weather earlier this week. Temperatures will start out in the 40's to 50's in the valley on Friday morning and will end up in the mid to high 70's in the afternoon. Foothill areas will also start out in the 40's to 50's, but will only top out in the 60's to low 70's. Higher elevations will dip into the 30's to 40's overnight and will top out in the 60's to low 70's on Friday afternoon .
Low pressure moves off to the East as we head into your Memorial Day Weekend and high pressure will be building through our region through the remainder of your 7 day forecast. Valley areas are projected to climb into the mid 80's on Saturday and into the low 90's on Sunday. Foothill and mountain areas are projected to climb into the 70's on Saturday and then into the 80's on Sunday.
We'll be staying dry and getting even hotter as we head into your Memorial Day on Monday. Valley areas are currently projected to end up in the mid to high 90's on Monday and then high 90's to low triple digits from Tuesday through Thursday of next week. Overnight low temperatures are only expected to fall into the 60's for the middle of next week, so it does not appear we'll see much relief from the heat even at night. Foothill and mountain areas are expected to top out in the mid to high 80's on Memorial Day and then in the high 80's to low 90's from Tuesday through Thursday of next week. Please make sure to plan ahead to stay safe with the hotter weather on the way. Sensitive groups may be susceptable to heat related illness. Dress for the heat, stay hydrated, limit your time outdoors, and make sure to wear sunscreen if you do need to be out and about.
