.KEY MESSAGES... * Dry front pushes through the region late today and early Friday. Gusty winds/low RH on Thursday bring elevated fire weather concerns east of the Cascades. There is a low chance (5%) of thunderstorms across eastern Siskiyou, Modoc and southern Lake counties late this afternoon and this evening.

* A low pressure moves over the area and brings chances for showers on Saturday, highest north of OR/CA border and along/west of Cascades. 15-25% for thunderstorms from the coast to the Southern Oregon Cascades. Strong, gusty winds east of Cascades possible.

* Significantly cooler Saturday and Sunday, high temperatures around 15-20 degrees below normal.

* Dry conditions return Sunday with continued cool temperatures. Gradual warming trend Monday through Wednesday.

A shortwave trough centered to the north will bring a dry front into the area late today and early Friday. This pattern will result in slightly lower temperatures, breezy to gusty afternoon/evening winds, and some cumulus build ups. Temperatures will trend 2-5 degrees cooler today but will still remain above normal across inland areas. The combination of gusty winds and dry afternoon humidities will bring elevated fire weather conditions to areas east of the Cascades. Additionally models are indicating more mid level moisture moving up from the south this afternoon and evening, which combined with instability will bring some cumulus build ups and a low chance (5%) for thunderstorms, mainly across eastern Siskiyou, Modoc and southern Lake Counties. Gusty outflows may accompany any buildups or thunderstorms.

High temperatures trend 7 to 10 degrees cooler on Friday as the base of a broad trough remains over the region. Breezy to gusty winds are likely again Friday afternoon, especially east of the Cascades.

A stronger low drops south Friday night and moves over the area on Saturday. This will bring much cooler conditions on the weekend. High temperatures are expected to be 15-20 degrees below normal on Saturday! Model guidance and ensembles continue to shower chances for showers on Saturday, especially along/west of the Cascades and north of the OR/CA border. Amounts won't be nearly as much as the most recent system, but generally 0.15"-0.25" for the coast, from the Rogue/Umpqua Divide north (Douglas County) and into the Southern Oregon Cascades. Across Josephine and Jackson counties, expect lower amounts of a few hundreths to a tenth of an inch in showers. Instability with this low will bring a chance (15-25%) for thunderstorms on Saturday, mainly from the coast inland to the Southern Oregon Cascades. East of the Cascades, there are lower chances for showers (10-40%). Northern California will be drier with very low (5-20%) chance for showers.

This low quickly shifts east of the area on Sunday. So, expect dry weather with lingering cooler than normal temperatures. Morning lows may dip down to near or below freezing for areas east of the Cascades early Sunday morning. Then, early next week, expect a gradual warming trend Monday through Wednesday with temperatures likely to return to near or slightly above normal by Tuesday.
