.KEY MESSAGES...

* Warming temperatures the first half of the week with renewed
  snowmelt and increases on rivers and streams, however, no flooding
  is expected.

* Shower and thunderstorm chances increase through the week, with
  the highest coverage anticipated Wednesday and Thursday.

* Cooler temperatures Thursday into Friday, with falling snow
  levels. This will be short-lived with warmer and drier conditions
  as we head into Easter Weekend.

.DISCUSSION...

* Warmer temperatures will be on tap through Wednesday with highs
  reaching into the 70s, possibly 80, for lower elevation valleys
  and about 10 degrees cooler than that for Sierra Valleys. With the
  warmth, we`ll see renewed snowmelt on area rivers and streams. At
  this point, the only river reaching monitor stage is the West Fork
  of the Carson at Woodfords, but all area waterways will see an
  increase in volume. Remember that rivers are extremely cold (water
  temp in the 40s to near 50) and shock will quickly set in if you
  jump in.

* Rather interesting set up this week as an area of low pressure
  approaches the west coast with multiple vorticies rotating
  inland. This will set the stage for cumulus development and a
  10% chance for showers and thunderstorms over the Sierra
  near/south of Tahoe by Monday afternoon, increasing in coverage
  and probability by Tuesday and Wednesday as that initial low
  shifts inland. Simultaneously, another low originating from
  Canada will drop south on Thursday. As the associated jet dives
  into the area on the backside of this low, it will bring the
  dynamics to help organize shower and storm development Thursday
  afternoon and evening. We are also likely to see pellet showers
  from this system as well.

* While ensembles are in much better agreement on this feature,
  the smaller scale details still need resolving and these details
  will determine where the location of heaviest precipitation
  and/or best thunderstorm coverage will occur. These type of
  "bowling ball" systems are notoriously tricky as they close off
  from the main flow, and are quite common this time of the year.
  As the low continues to dive south, deformation bands of
  precipitation on the north side of the low will bring continued
  shower chances to the region on Friday, primarily from US-50
  south.

* Snow levels will rapidly fall with this system on Thursday,
  dropping as low as 4500-5500 feet, per latest ensemble guidance.
  Admittedly, there is still quite a bit of spread, but that
  appears to be more timing related. Coldest conditions could come
  as early as Thursday afternoon, or as late as Friday morning. As
  far as travel concerns -- we`ll need to watch how the smaller
  scale details evolve, but for now, plan for potential minor
  concerns in the Sierra.

* This storm will also bring gusty north winds to the region
  Thursday, turning northeast on Friday. Minor recreation and
  travel impacts are possible, but there are no signs currently
  that this will be a "damaging" (i.e. gusts 60+ mph) wind event.

* Warmer conditions will return as we head into Easter Weekend, so
  outdoor activities look good at this point, unlike the snowy
  Easters of the past couple of years. -Dawn

.AVIATION...

* Overall northeast-east flow across the region, with generally
  light winds surface and aloft. A few locations are seeing gusts
  up to 15 kts due to terrain influences, such as KCXP. Light
  south-southeast flow to continue aloft through Tuesday.

* Look for cumulus development over the Sierra near/south of KTVL on
  Monday afternoon, with a 10% chance for showers and/or
  thunderstorms. Storm chances and coverage will increase into mid-
  week with periods of lower ceilings and terrain obscuration
  possible. -Dawn
