July 9 Forecast

The high pressure ridge that brought the excessive heat to our area over the weekend will start to shift back to the east over the next several days.  We’ll be a few degrees cooler today, but still well above normal.  Along the coast expect winds to pick up by the afternoon and stay strong for the next several days as a cut-off low approaches the coast.  The marine layer will produce fog along the coast for the next couple of days and the Umpqua Basin may see early morning fog for he next couple of days as well. 

While thunderstorms stayed north of the area yesterday, the chance for isolated thunderstorms continues this afternoon east of the Cascades, with the biggest threat in north Lake and Klamath counties.  Today marks the best bet for storms over the next couple of days, but if we’re able to get some middle level moisture brought in by the western monsoon we’ll have the chance for thunderstorms again later this week and through the weekend.  For now I’m keeping the forecast hot and dry, but that may need to change as we approach the weekend.

The cut-off low that will move into Oregon in the middle of the week will return hot temperatures to the area.  Ushering in heat from the Mexican Plateau, the Gulf of Mexico and the Southwest.  We’ll see upper-90s return to the Valleys and Northern California which is about ten degrees above normal for this time of the year.  Depeding on the strength of the cut-off low and the duration of time it spends over Oregon determines how hot we’ll get this weekend.  We could see some triple-digits in the forecast if this system is strong enough.  For now I’m keeping highs in the upper-90s, but that may be altered over the next couple of days as confidence increases.

Thanks for logging on and have a great Monday!
