Summer Heat Wave Thru Saturday

High pressure will push inland tonight and the hot, sunny and dry weather will continue through Saturday with highs remaining 10 to 15 degrees above normal. While highs will not be quite as hot as they were today, the difference will be hard to notice.  A low pressure system in the Southwest will push north on Thursday and may provide enough instability and moisture for isolated afternoon thunderstorms along and east of the Cascades into Friday. Moisture will be the limiting factor with this disturbance but the potential is there.

This low will kick out of the area Saturday and sunny and dry conditions return. Sunday a long-wave trough will begin ushering in disturbance and thus a chance for showers and thunderstorms. The timing and strength of the disturbances is uncertain at this time, for now it’s worth a mention and we will continue to monitor this system into the weekend. What is certain is that temperatures will be significantly cooler, instead of the 10 to 15 degrees above normal we’ve been this week, we’ll be about 5 degrees below normal!

Thanks for logging on and have a great evening!
