DISCUSSION (Today through Sunday)

Key Points:

* Only minor impacts expected the next several days * Warm, above normal temperatures continue this week * Low pressure remains to our south through midweek - Isolated showers and thunderstorm chances continue today - Similar setup for Tuesday with isolated thunderstorms * Drying trend starts Wednesday

Further Details:

A closed low remains to our south and will maintain an east to northeast flow aloft. As we reach peak heating and convective temperatures, we should see showers and isolated thunderstorms this afternoon and early evening. This would be mainly for areas along and near the Cascades, westside areas south of the Umpqua divide, and northern California. We are not expected severe weather, but deep mixing and very dry low levels (inverted-v profiles) could lead to occasional gusts around 45 mph. This would be very isolated to the strongest storms today through peak heating. Lightning will be the other hazard. This closed low doesn't move much Tuesday, and we may see a very similar outcome with isolated thunderstorms over these same areas through peaking heating. Similar threats would be expected Tuesday with occasional strong gusts and lightning as the main threats.

High pressure aloft starts to nudge in Wednesday and will maintain dry conditions through the end of the week. Temperatures near 90 degrees will come to fruition Wed/Thurs. Slightly cooler temperatures expected on Fri/Sat, but temperature near 90 will be possible again on Sunday.

AVIATION

Areas of fog and low clouds are expected through today along the coast which the possibility of these low clouds spilling into the Umpqua basin. These areas could see IFR/MVFR conditions this morning and early afternoon with some improvement today for KRBG. However, KOTH will likely see these low clouds stick around throughout this cycle. Otherwise, isolated showers and thunderstorms are possible through peak heating, which could impact both KMFR and KLMT. At this time only went with vicinity as confidence is low given the isolated nature of showers today.
