Area Forecast Discussion National Weather Service Reno NV 156 AM PDT Sun May 12 2024

SYNOPSIS

Above normal temperatures are expected today with chances of Sierra showers and storms in the afternoon. Steady warming continues through the week with afternoon showers and storms south of the Tahoe Basin possible on Monday and Tuesday. Cooler weather and increased shower chances are favored for next weekend.

DISCUSSION

An encore of overall pleasant weather is in store for Mother's Day, although there are a couple of items to keep in mind if you venture outdoors today!

1) Warm daytime temperatures beneath mostly sunny skies:

Daytime highs are expected to climb into the upper 60s to 70s for Sierra communities and upper 70s to mid 80s for much of western Nevada. While passing clouds will allow for a brief cooldown in some areas this afternoon, most areas will experience abundant sunshine so be sure to stay hydrated and wear sunscreen if spending extensive time outdoors. One final note: While the weather will be warm, area waterways are not so avoid plunging into creeks and streams!

2) Potential for afternoon Sierra showers and isolated storms:

Effective differential heating and a slight increase in moisture will promote a 15-25% chance of showers and isolated thunderstorms this afternoon in the Sierra. Best potential favors the higher terrain of Alpine and Mono County with a secondary maxima across Lassen and far northern Washoe counties. Timing of showers and storms may begin as early as 11 AM PDT and lasting as late 7 PM PDT, though the most likely timeframe will be between 2-5 PM PDT per latest HRRR and CAM guidance. Any developing thunderstorm will be capable of brief downpours, gusty winds, and occasional lightning.

The upcoming week will feature above normal temperatures with chances of showers and isolated thunderstorms Monday and Tuesday afternoon. Monday will be the most favorable day, especially in the Sierra from the Tahoe Basin southward and perhaps into far western Nevada south of US-50 where chances reach 30-40%. Potential declines a skosh to 20-30% on Tuesday and favors a similar area as Monday.

The remainder of the week will be dry and is trending towards a warmer scenario as latest ensemble guidance converge on the robust eastern Pacific high solution. Chances of KRNO reaching 90F now stand around 40-50% for Thursday and Friday per blended guidance.
Cooler weather with increasing chances of showers is favored for next weekend and beyond.

AVIATION

The main weather concern will be the potential for showers and isolated thunderstorms in the vicinity of KTRK/KTVL/KMMH this afternoon. Odds of a thunderstorm within 10 miles of these terminals are around 10-20% with potential impacts of gusty erratic winds, reduced CIGS/VIS, and occasional lightning. Otherwise, VFR conditions are expected to prevail.
