KEY MESSAGES

* Foggy conditions may reduce visibilities along roadways in Sierra valleys this morning.

* A slight chance of showers and isolated thunderstorms will reside across far NE California and NW Nevada this afternoon.

* Above normal temperatures prevail next week with cooler, unsettled weather possible next weekend.

DISCUSSION

Clearing skies and light surface winds should encourage fog formation early this morning across N Sierra valleys -- especially after a few days of humid, showery weather. Fog is most likely to develop in the Martis and Sierra valleys, with a lesser likelihood in/near the Tahoe Basin. Expect reduced visibilities in areas where fog is present, including the stretch of I-80 near Truckee.

Shower and storm potential has trended downward today, but there does seem to be enough instability to support low probabilities (10- 20%) of isolated showers and thunderstorms across far NE California into NW Nevada this afternoon. Shower/storm chances decrease further Sunday afternoon, although a PacNW low will maintain very low 5-10% odds along the higher Sierra terrain.

Temperatures warm to near average this weekend with daytime highs in the 60s and 70s. Further warming is expected next week, yielding well above normal temperatures by the middle of the week. The Tuesday through Thursday timeframe looks to be the warmest with highs flirting with 80F and 90F for Sierra communities and lower NE CA/W NV valleys, respectively. Ensembles are hinting at a pattern change late next week into next weekend, which may usher in cooler temperatures, gusty winds, and increased shower/storm chances. However, confidence is low being about a week out.

AVIATION

Fog and IFR/LIFR conditions at KTRK will be the primary concern through the morning, particularly between 10Z and 16Z. Shallow fog/BR may briefly develop at KTVL early this morning, but confidence is lower. Shower and thunderstorm activity will remain north of main terminals (15-20% odds at KSVE), but increasing low clouds may result in mountaintop obscuration this afternoon.
