.SYNOPSIS...

Cooler weather along with periods of showers and thunderstorms

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.
