KEY MESSAGES

* Showers and isolated thunderstorms continue through Saturday afternoon, followed by dry weather Sunday into next week.

* A warming trend will return temperatures to seasonal averages this weekend before becoming above normal much of next week.

DISCUSSION

A band of remnant showers originating from yesterday's thunderstorm activity in Oregon and Idaho is being directed into northern California as noted on early morning radar. This band should mostly stay west of the Sierra with light rain sneaking into E Modoc and Lassen counties. Shower coverage will extend eastward into NW Nevada as the morning progresses, providing light rain to areas north of Reno. Shower activity decreases in the afternoon and becomes more spotty. Isolated thunderstorms will be possible in a couple areas this afternoon: 1) far eastern portions of Pershing and Churchill counties (15-20% odds), and 2) near the Oregon border (15% odds or less). Showers and thunderstorms return Saturday afternoon, but will continue to be isolated and confined to far NE California and near the Oregon border. A few higher resolution guidance sources leave open the potential for a couple of storms popping up in the Reno-Tahoe region or west central NV, but confidence is lower for storm activity extending this far south.

While it won't be too noticeable today, temperatures will warm to some extent each day through the middle of next week as our stubborn low pressure finally departs to the east. Today's highs will only be a few degrees warmer compared to yesterday, but will return to the mid-upper 60s and 70s over the weekend. Nighttime lows will also gradually warm, but will remain chilly in colder Sierra valleys into the weekend as temperatures fall to near freezing. Additional warming is expected through midweek, when highs will be flirting with 80F and 90F for Sierra communities and lower NE CA/W NV valleys, respectively. These daytime highs will support a widespread minor (1 out of 4) HeatRisk with moderate (2 out of 4) HeatRisk developing in lowest W Nevada valleys Wednesday and Thursday. Make plans accordingly, and be sure to practice your heat safety precautions if your plans do take you outside this upcoming week!

AVIATION

Isolated showers are expected through the afternoon, resulting in periods of mountain obscuration and CIGS/VIS reductions. Showers and thunderstorms return Saturday afternoon, but even the best chances are only 10-20% and will favor KTRK-KRNO-KCXP-KMEV. Showers may develop south of these terminals (i.e. KTVL-KMMH) but odds are 10% or less.
