Latest update from DWP shows the Winter of 1969 record up on Mammoth Pass broken with 88.00 inches of water through March 29th, eclipsing the old record of 86.5 inches….Although this past storm that dropped light amounts has not been tallied yet, the record has already been broken….

The Manuel Survey will be taken possibly today or this weekend, will be released to the public, possibly later next week.

Congrats to everyone that survived the Great Winter of 2017…the biggest water year through April 1st in at least 77 years.

My records on Mammoth Pass go back to 1940.

Northwest slider to bring wind light snow and cold temperatures to the eastern sierra.

High Wind Warning Thursday through 8:00PM tonight.

A typical spring storm is in process today Thursday. It will bring 10 feet of wind and 1 to 3 inches of snowfall. Highlights are the winds, as initially, the upper jet moves into Northern CA Wednesday night with west wind, then backs strongly from the Northwest Thursday as the system digs SE to the Eastern Sierra. Although there is not much moisture with the system, the front is pretty energetic. It is expected to bring a quick burst of moderate snowfall to Mammoth Lakes with the front itself Late this morning and into early this afternoon

The upper jet will drive down through the Owens Valley tonight as a classic High Wind event that extends from Mono County today through most of Eastern CA to the Colorado River Valley by this afternoon.  Antecedent conditions will make for quite the gradient as Bishop reached 80 degrees on Wednesday. A 500MB-1000Mb thickness pool of 540DM will drive through eastern slopes of the sierra late tonight and remain over the central and southern Great Basin Friday morning and into the afternoon. This will make for an unseasonably cool Friday with gusty NE winds over the crest.

Weekend Outlook: 

Expect light breezy weather, not windy Saturday and Sunday with most breeze over the crest diminishing during the day Saturday. Over all, it looks like a fair weekend with a warm up! The next weather system approaches Northern CA Sunday with winds on the increase again Sunday night. Snow showers possible Sunday night and Monday with cooler temps.  Warmer weather with increasing clouds are  expected toward the middle of next week.

Longer Range:

Major Long Wave trough setting up in the Gulf of Alaska during the 6th/ 7th with the possibility of several larger storms during the 2nd half of next week. I will have more detail in my next WX letter. At the Moment we may be influenced by an Atmospheric River that is mainly focused upon Northern CA the next weekend.

High Temperatures the next few days will be in the low 40s climbing to the mid 50s for Saturday and Sunday.

Nighttime lows will be in the teens and 20s.
