Area Forecast Discussion National Weather Service Reno NV 108 AM PDT Fri Apr 26 2024


SYNOPSIS

Cooler weather along with periods of showers and thunderstorms will persist through early Saturday. Potential thunderstorm risks include gusty outflow winds, dangerous lightning, and localized heavy rain and/or small hail. Drier weather and a slow warming trend are expected to return Sunday through the middle of next week.

DISCUSSION

Key Points:

* Cooler with showers through Saturday Morning: Widespread valley rain and mountain snow showers will be possible today through early Saturday morning. Sierra passes may see snow, but recent warmth will limit impacts. Today will be the coldest day of the week as temperatures back down below normal. Yay.

* Weekend Outlook: A few light lingering showers may stray by Saturday morning, but otherwise the trend will shift to warmer and drier conditions for much of the weekend. Plan on temperatures warming back up to near normal and then rising above normal by early to mid next week.

* It's gonna be May: There are still signals for additional storms to push through the region late next week. Enhanced breezes, cooler temperatures and showers are all possible for the first few days of May.

The main trough along with its cold front will drive through the Sierra and western Nevada today and kick off some more showers across the region as well as some brisk northwest breezes. There is 15-20% chance for a thunderstorm or two, so be prepared if you're outdoors for any rapid changes in the weather. Rain totals will be relatively meager, but a welcome bit of moisture for the May flowers. Chances for 0.5" of QPF are around 40% the Central Sierra and 30-40% for the Tahoe Basin and Eastern Sierra. Chances for over 0.1" of QPF are around 30-40% for far western Nevada and northeast California valleys, and 70-80% for the Basin & Range.
Keep an eye out for some light accumulations along the Sierra passes, especially through this morning.

Otherwise, the main trough migrates eastward across the Rockies on Saturday leaving behind drier conditions and a warming trend through Wednesday. Plan on typical afternoon breezes each day under the influence of zonal, westerly flow. Roughly 60% of the ensemble solutions signal for more active weather to return by late next week. So May is hedging toward a cooler and possibly wetter outlook for now.

AVIATION

* Light rain showers overnight will taper off for western Nevada terminals while Sierra showers will persist for much of the day as the cold front pushes through the region today. Heavier rain and high elevation (above 7000 ft) snow showers are expected to arrive around 19z for Sierra terminals and 21z for western Nevada terminals.

* FL100 winds will shift to NW and decrease after 21z. Surface wind gusts will be around 20-25 kts for most terminals, although gusty and erratic winds near thunderstorms will be possible (20% chance).

* Showers will dissipate rapidly after Sat 04z for all terminals.
Plan on VFR conditions with typical breezes Saturday and Sunday.
